Face ID. what is it, how it works

What is Face ID? It is a secure authentication system that is able to unlock the device and pay for purchases by recognizing the owner’s face.

Provide this capability with TrueDepth cameras, which work together to scan, perceive, and recognize a structural map of your face. A few words about the components of the system:

  • Point Projector. about 30,000 invisible points are projected onto your face, creating an individual map taking into account all the outlines of your face;
  • Infrared camera. is responsible for the process of reading information about the dot structure, creates an image in the infrared spectrum and transfers the data to the Secure Enclave module, which is built into the A11 Bionic processor (at this stage, the conformity and comparison of the face and the set early dot structure of the owner’s face are checked) ;
  • IR emitter. emitting an invisible beam of infrared light that allows iPhone X to recognize your face even in the dark.

iphone, face, working

Face ID is a powerful security system that cannot be tricked by photos. To unlock the iPhone X, you need to look specifically at your smartphone. with closed eyes or looking at the floor, it will not work to wake up the smartphone. over, the system works even at night. Fans of experiments with appearance should not worry: Face ID will react to you, even if you grow a beard, put on glasses, paint or put on a winter hat and scarf.

When creating a 3D model of a face, the Face ID system is more compromise and easy to use, which cannot be said about the iris scanner from Samsung, where unlocking a smartphone requires clarity and dexterity. matching your eyes and scanners while walking, you must agree, is more difficult.

Face ID. unlock your smartphone using your face

It’s not news that Apple creates revolutionary things that later become the benchmark for the smartphone business. This was the case with Touch ID, which appeared in the iPhone 5s and has become a musthave element for modern devices. This time, Apple has prepared Face ID technology, which, as expected, other smartphone companies will try to copy and use, because it is hard to deny that this is truly a breakthrough innovation. In this article, we will go through this technology in detail, consider its main advantages and disadvantages, and draw our conclusion.

Face ID versus Touch ID

It is no wonder that Apple lovers will be divided into two camps: adherents of the Face ID innovation and seasoned oldfags, lovers of Touch ID. It’s hard to say which is better, we have only facts. For example, for a fingerprint scanner, the chances of unlocking an incorrect fingerprint are 1:50 000. But unlocking with Face ID allows several times fewer errors. 1: 1 000 000. Of course, it is quite difficult to compare the speed of the two systems, but hypothetically Taking into account all the owner’s movements aimed at activating the smartphone, Face ID will remain simpler, more convenient and faster. unlocking occurs with just one movement. it’s like looking in a mirror. But the twins with the iPhone 10 will have to get nervous. most likely, the system will not find the differences between you and your sister or brother, and fingerprints, after all, are a unique sign.

How to turn off Face ID on iPhone X?

Not everyone uses the fingerprint scanner, which means that Face ID will be bypassed by many. Perhaps you played around with this technology and now you can’t get rid of the annoying face unlock? To disable Face ID on iPhone X, do the following:

  • We go to “Settings”. “Face ID and Password”. click “Disable”.
  • Restarting iPhone 10.
  • Making 5 unsuccessful attempts to unlock iPhone 10.

How to set up Face ID on iPhone 10. instructions

Not everything is new. complex. Face ID, like Touch ID, uses the registration of user data (in our case, a face), after which the function can be safely used. Now in more detail:

  • Let’s say your iPhone X is already on and pretty much all set up. We take the phone, go to the “Settings” menu. “Face ID and password”, click “Save”. Now your iPhone 10 will briefly notify you of your actions on the screen, press the blue “Start” button. The front camera will turn on and you will need to wait a couple of seconds until a circle appears with white marks around it. Registration software will overlay 3D markings on the display to show your line of eyes and face.
  • Now you need to slowly roll your head in a circle in any direction until all the marks from white to green. Click “Continue”, and then turn your head in a circle again until progress is made. After a successful scan, the iPhone X will create a 3D model of your face, by which, in fact, it will recognize you.

How to set up Face ID on iPhone X?

Full description of Face ID technology

With the release of the iPhone 5S, the fingerprint scanner, referred to as Touch ID, debuted, and for 5 years now this technology has served faithfully not only to owners of iPhones of different generations, but also to users of Android smartphones. 2017 was marked as the year of frameless devices, so all manufacturers began to install a fingerprint scanner on the back. the majority do not like such a decision, what is there to hide. Before the release of the iPhone X, many argued about where Apple would place the Touch ID: some said that it would be located inside the display, the latter stood for the fact that, like everyone else. behind, others predicted Touch ID on the side like Sony smartphones, but the latter were skeptical at all, allegedly they would cut out fingerprinting altogether. Who was right? That’s right, skeptics, however, Touch ID was removed for a reason, it was replaced with advanced technology that will not appear in competitors’ devices for the next year and a half. Face ID.

Face ID. this is another way to protect personal data (the CIA just collected all the prints from you, now it’s time to know everyone in person) from unwanted viewing by third parties. If even a child can already set up the fingerprint scanner, then with Face ID it is somewhat more difficult, since the technology is new. Let’s figure it out.

Why Face ID may not work on iPhone

The security system may not work in different cases. First of all, you need to make sure that the user’s phone or tablet supports this function. After that, you should follow the steps below and after each of them check if the problem is resolved:

  • Check for updates. Make sure your iPhone or iPad is up to date with the latest possible iOS version.
  • Check your Face ID system settings. To do this, go to the main menu of the device, find the “Settings” icon there, select the “Face ID and Passcode” section. Make sure the system is configured correctly and the function the person is trying to use is enabled.
  • Make sure the camera taking the picture is not covered or stained by anything. If it is covered with a cover or low-quality protective film, the system will not be able to recognize the owner’s face. If this is true, then when trying to set up Face ID, the user will be prompted with a message stating that the camera is obscured, an arrow will appear pointing to the camera itself.
  • Make sure that the user’s face is not covered by anything. It is necessary to check whether the nose and mouth are completely visible to the camera. The technology allows you to work with the camera and with sunglasses, but sometimes the latter have a special coating that blocks the infrared color used by the camera. If this is the case, then you need to use Face ID without sunglasses.
  • Make sure the user’s gaze is directed exactly towards the camera. Face ID only works if the gadget is in portrait orientation and the person is looking directly at the camera.
  • Set up an alternate view. Since people can change over time and the protection system does not recognize them, you can set Face ID to an “alternative view” so that it can recognize a person’s face.
  • Try to reset Face ID settings. If none of the above helped, then you need to reset the parameters. To do this, go to the “Face ID and Passcode Settings” and click on the “Reset Face ID” button. After that, the system needs to be configured again by clicking “Configure Face ID”.

Important! There are many reasons for the incorrect operation of the system. It is necessary to check them all step by step and correct them if possible.

All sensors are located on a special panel

Verifying TrueDepth Camera Operation

Before setting the function, make sure that no foreign objects are blocking the view of the camera. You can check the camera in the same settings as in the previous paragraph. If it is closed or smeared with something, the system will notify the user about it. To start the test, you need to place the phone in front of you in portrait orientation at arm’s length or 25-50 centimeters from your face and look directly into the lens.

Note! A breakdown could occur if a non-original (fake) phone was purchased or the gadget fell.

An alternate look is also included with the main settings menu

Face ID not working on iPhone X. what to do

Modern gadgets have gone far ahead of their predecessors, push-button phones. They have better cameras, more internal and RAM memory, a clear and high-quality display. They are being improved not only in terms of general functionality for entertainment and convenience, but also in security measures. Apple not so long ago announced its development of Face ID, which replaced the fingerprint scanner and the “Home” button completely. This article will explain what Face ID is and why Face ID sometimes doesn’t work on iPhone 10.

Checking Face ID settings on iPhone

One of the most common problems is system misconfiguration. Face ID may simply not be configured on the user’s iPhone or iPad. If so, then:

  • You need to go to “Settings”.
  • Select the “Face ID and Passcode” section.
  • Click on “Set up Face ID”.
  • Make sure that the device is in vertical projection, place it in front of your face and click “Proceed”.
  • Place the face in the frame and make circular movements with it according to the instructions so that the sensors can fix it from all sides and take a 3D picture.
  • Click “Next” and follow the same procedure.
  • Complete the procedure.

If a regular password has not been set, you can specify it in the next step. To select features that use Face ID, you must return to the “Face ID and Passcode” section.

What is Face ID on iPhone

Face ID is a technology that helps you securely unlock your iPhone or iPad, confirm online purchases, sign in to apps, and more with just one glance at the front camera.

Face ID lets you scan your face to log into your iPhone securely

The system compares the user’s face with the photo that the iPhone owner originally entered when setting it up and decides whether to allow him to control the phone or not. The photos themselves are taken with an iPhone 10 using a special camera called the True Depth Camera.

Many were indignant when they saw the area on the new gadget, which is located on the upper front panel, because it does not allow the screen to be fully expanded. This was done for a reason. This area is just teeming with various sensors and scanners. In addition to the usual front-facing camera, microphone, speaker, light and proximity sensors, it manages to fit the backlight system and infrared system.

It is from the latter that the very camera that takes pictures of the face consists. The functionality allows you to photograph a person in 3D, and when checking this image to compare with a person’s face. Infrared illumination is needed in order to take the clearest pictures even in low light conditions.

Important! The sensor directs about 30 thousand invisible points to the face, based on their location and determines whether a person’s face is suitable.

There are times when Face ID does not work on iPhone X. Why this happens and how to fix the problem will be described in the sections below.

Correct phone and face positioning for Face ID to work correctly on iPhone

In order for the system to capture and store a high-quality image, it is necessary to select a suitable room with good lighting. Don’t rely entirely on the infrared sensor to help you take photos in dim light. To create a correct snapshot, you need to:

  • Set the phone to scan the owner’s face.
  • Place your face straight and towards the light source.
  • Place the gadget vertically, that is, the way it is usually held in the hand when surfing the Internet.
  • Shooting should be done at arm’s length (ideal range 25 to 50 centimeters).
  • The eyes should be looking at the camera at all times. This concerns not only the settings, but also subsequent unlocks.

Keep your phone straight or it may stop scanning your face

How to reset Face ID on iPhone

Sometimes you need to completely reset your Face ID settings. This is necessary when the system for some reason does not work correctly, does not identify a person under any pretext, or a person wants to give a phone to his friend for a while. In this case, the parameters are reset. To do this, you must adhere to the following step-by-step instructions:

  • Go to the main menu of the phone.
  • Find the “Settings” icon and select it.
  • Click on the item “Face ID and passcode”.
  • Select “Reset”.

It is necessary to change the system settings as a last resort

The article covered what to do if Face ID stopped working on iPhone X and how it should be configured correctly. There are many reasons why the system may not work. You should go through the list and try all possible settings before replacing the device under warranty or buying a new one.

What to do if Face ID isn’t working?

If Face ID does not work, and the iPhone displays a system message about a problem with Face ID, it is most likely that the reasons for this lie in a hardware malfunction of the TrueDepth camera or sensors responsible for recognizing the user’s face.

The reasons for the hardware malfunction, in turn, may be damage to the sensors or the camera when dropped or other mechanical impact, or due to moisture getting inside the phone.

Face ID doesn’t work on iPhone X, iPhone XS, or iPhone XR. What to do?

Face ID takes iPhone security to the next level, introduced with the iPhone X. Future models. iPhone XS, iPhone XS Max, and iPhone XR. were also equipped with the wearer’s face recognition technology, which works even more quickly. Face ID facial recognition works smoothly and provides the highest level of data security. However, over time, some users may face the fact that Face ID does not work on their phone, or it does not work correctly. Let’s understand the problem in more detail.

Why Face ID doesn’t work?

If Face ID does not work on your iPhone, the reasons for this may be different and by no means always contacting a service center is required to solve them. Let’s take a look at the top reasons why Face ID might not work and how to fix the problem yourself.

  • If iPhone doesn’t recognize your face, check for dirt on the top of the device. where the TrueDepth camera and infrared sensors are located, which are responsible for scanning the face. Thoroughly clean the glass surface and test Face ID afterwards.
  • Try turning off the Attention Alert feature. The essence of its work boils down to the fact that the phone will not be unlocked if you do not look at it with emphasis directly. You can disable the function in the phone settings (Settings. General. Accessibility. Attention recognition). It should be noted that disabling this feature can reduce the security of Face ID. to unlock the phone, it will be enough to bring it to your face (even, for example, when you are sleeping).
  • Reset Face ID settings. You can also do this through the phone menu (Settings. Face ID and passcode. Reset Face ID). After performing the reset, you will need to re-scan the face and set up Face ID step by step.
  • Hard reset your iPhone. You can read about how to do this on devices without a physical Home button in the article “What to do if the iPhone X is frozen and does not respond to anything.”.

In everyday use of the iPhone, there are times when Face ID does not work. he shouldn’t work. The official Apple website provides several options in which this can happen.

  • The device was just turned on or rebooted.
  • than 48 hours have passed since the device was last unlocked.
  • Six and a half days have passed since the last time you unlocked your device with a password, and 4 hours have passed since the last time you used Face ID.
  • The device received a command to block from a remote user.
  • Five unsuccessful attempts were made to recognize the face.
  • The process of turning off the device / starting the “Emergency SOS” function has started (holding one of the volume buttons and the side button at the same time for 2 seconds).
  • If the battery charge is below 10%.

In such cases, you may need to enter the passcode set on the device to unlock your phone, or you may need to unlock your iPhone with your Apple ID.

The firmware has also undergone changes. After all, the “home” button is gone, and the screen has changed dramatically. It has become larger, therefore, there is more space for content too.

The internal interface of the iPhone has changed, but it is done in such a way that some changes are not noticeable at all. And you can immediately get used to most of them due to their convenience.

The only inconvenience is the language switching button. Located under the keyboard at the bottom and you can overlook it at once.

Although it is not very convenient to press, but after a week you can get used to it. But the keyboard “Tens” has become more beautiful and more convenient.

IPhone energy

The capacity of the “dozens” battery is 2716 mAh. 2 hours of operation for the iPhone 7:

  • when listening to audio. 60 hours;
  • watching video. the battery will last for 13 hours;
  • with continuous talk, the battery will last up to 21 hours;
  • those who like to climb on the net have less. 12 hours, which, in principle, is quite a lot.

Also, the iPhone X supports fast charging. Half the charge is gaining in half an hour! Of course, the iPhone can charge wirelessly using the Qi docking station.

iPhone is afraid of water?

iPhone X is dust and water resistant. If you put it in water in working order and turn on the music, then it will continue to work and sing as if nothing had happened. iPhone is IP67 protected.

We do not recommend or encourage you to check your iPhone in this way. The phone is needed to make calls, not to swim.

Apple iPhone X. birthday and price

  • The first episode was released on November 3rd
  • The most expensive smartphone in its segment
  • comes in 256GB and 64GB options

for a model with 256 GB, and for 64 GB you need to pay 79,000 rubles. But Apple connoisseurs are eager to buy these models.


The six-core processor of the A11 Bionic version is 25% more powerful than the previous versions. It is capable of processing billions of operations per second! iPhone 10 does not always use not all 6 cores, but only 4, for everyday tasks. The other two are connected when the smartphone is under heavy load. This technology allows you to handle most operations with negligible energy consumption.

The iPhone X chip makes the application and games look realistic. A new level of smoothness and color depth allows you to fully enjoy it.

According to the tests carried out, the tenth iPhone became the leader in terms of data processing speed and performance:

Geekbench 4. testing in the single-core segment.

BaseMark OS 2.0 test. the gap with androids is already smaller, but still the iPhone is in the first position.

Also, do not forget that most Androids have little memory of their own. They support cards, but apps are mostly installed in system memory. Lack of space causes braking. The iPhone, especially in the 256 GB configuration, does not have this problem.

The Face ID scanner has replaced Touch ID. Using this function in the tenth iPhone, you can unlock, verify your identity in Apple services.

Face ID consists of an infrared camera, emitter and point projector. Thanks to these elements, Face ID works extremely accurately and without errors.

Protection against accidental and fraudulent unlocks has been implemented. Masks and photos are not recognized by iPhone. The owner must look directly at the camera. Only then will the lock be lifted.
What’s cool is that if the owner’s appearance changes, the iPhone will recognize him. Thanks to machine learning technology. If you get older, fatter, or vice versa, the device recognizes you.

One drawback. you still have to touch the iPhone with your hand and slide your finger up from the bottom of the screen.
Face ID makes it incredibly easy to buy and download apps from Apple services. Previously, you had to enter a password or poke your finger to make a purchase and start downloading a file. Now you don’t need to do anything. The face scanner takes care of this.

Why Face ID doesn’t work on iPhone X, XS, XR. reasons and what to do?

Many owners of Apple smartphones are sometimes worried about why Face ID does not work on the Iphone X, and how can this be fixed? The presented function is a new stage of protection. The technology is considered unique, and Apple is the first company to use Face ID in phones. The described function is not used in all iPhone models, it is built only in X, XS, XS Max, XR. Let’s consider what problems can arise when using the program for face recognition, and how to solve the problems.

Why Face ID doesn’t work on iPhone X

The presented function may not function for various reasons, including mechanical damage and system failures. To determine the correct solution to fix the problem, you need to know the cause of the problem. The following factors are known today:

  • iPhone Refuses to Recognize Face? Check the TrueDepth camera for dirt first. Perhaps the infrared sensors are covered with dirt, and since they act as a face scan, the function simply will not work. Wipe the screen with a napkin and check if the program works.
  • The second reason is a system failure. The built-in technology is imperfect and in some situations a malfunction may pop up.
  • Mechanical damage. The user could drop the phone, which subsequently landed unsuccessfully, and the sensors and other technical components were damaged.

Also, the system may not function for the following reasons:

  • you have just launched your smartphone;
  • the phone received a special lock command from the old owner. Contact him, because you will need to provide your Apple ID;
  • charging on the phone is less than 10 percent;
  • for seven days you have not touched your smartphone or removed the lock from the screen. Unlock the gadget by entering the password;
  • you made five unsuccessful attempts and the device was unable to recognize your face.

What to do if Face ID doesn’t work on iPhone 10

If Face ID Iphone X stopped working, then try creating a second face. Go to the settings and find the FACE ID section, where you need to select a tab that allows you to re-update the previously added face or add a second one. It is recommended to adjust in a bright room, without dark glasses, loose facial hair, strong makeup, headgear. This will ensure the best possible performance of the technology.

The second way you can fix the problem is to turn off the Attention Awareness feature. The service in question includes several useful phone protection options.

For example, it has a setting that requires you to look directly at the camera without looking away. If the user does not direct his gaze to the sensors and does not raise the camera evenly enough, the smartphone will not be unlocked. To disable this parameter, you need to go to the Face ID settings on the iPhone and deactivate the item “Demand attention”.

Updating the iOS system can help fix the problem with Face ID. If you have not installed new versions of iOS for a long time, then most likely the reason for the failure of the recognition program lies precisely in this. Especially, this criterion applies to the tenth iPhone, where users had problems using the function on the 11th version of iOS. Upgrade the system to the 12th version of the operating system and most bugs will no longer be disturbed.

The next solution is to reset your phone. The option will bring the desired result if the malfunction was associated with a failure of system parameters. At the same time, restoring from a copy will not guarantee the disappearance of errors. It is recommended to perform a full reset and self-configuration of the device from scratch. Go to the phone settings and in the appropriate section click the reset button.

If the problem is related to damage to parts, what could happen after the unsuccessful fall of the smartphone. The sensors and sensors built in for the operation of Face ID are quite fragile and can stop functioning at the slightest impact. In this case, you should contact a mobile device repair service, where specialists will replace the necessary parts.

Incorrect display replacement

Has FaceID stopped working on iPhone X, XS, XR after a recent visit to the service with it? The function was probably damaged by the technician during the repair. Often this is due to fixing the camera, replacing secondary sensors or display. To avoid such breakdowns, the repair of these parts must be carried out separately from the replacement of FaceID components. But from time to time the masters neglect this rule for one reason or another.

Why FaceID doesn’t work on iPhone

There are several possible options for what could have happened to the phone and the function, and not all of them lead to a repairman. The Apple website has published a list of cases where face recognition works and should not:

  • the device was last unlocked with a password more than six and a half days ago;
  • FaceID was last used more than 4 hours ago;
  • blocked by remote access;
  • unsuccessfully used this feature five times in a row;
  • the device is currently shutting down or initiating an “Emergency SOS” call;
  • low battery power (less than 10%);
  • the device was not active for 2 days.

If Face ID does not work for the reason from the list above. use a passcode or Apple ID.

Dropped into the water

If the phone gets into water, parts are damaged by moisture. In the future, the problem may arise both because of this, and due to improper disassembly and assembly of the phone. All elements of the True Depth camera, especially the loop, are very sensitive and can cause a short circuit if they get wet. In this case, with each attempt to save information about a new person, a message about a breakdown will be displayed.

OS update

Do not forget to regularly update the operating system, if an error occurs, check if updates have been released. This can be done:

  • go to the “Settings” item;
  • go to the “Basic” tab;
  • scroll down and select the item “Software update”;
  • download and install all the necessary updates.

Apple often fixes various bugs in updates.

Film problem

One of the possible causes of the problem is closed sensors. A protective film protects them from dirt, dust and scratches. The screen needs to be cleaned regularly, and it is better to use the film with a cutout so that the sensors responsible for FaceID are always open, since you can make mistakes during the installation process.

A fall

If the iPhone is unsuccessfully dropped or bumped, it is possible that the True Depth functionality of the system may be damaged. It consists of very fragile parts, namely a point projector, an infrared camera and an infrared emitter, and it is impossible to predict what exactly will break upon impact. In addition, True Depth and the rear lower camera lens are closely related to each other, so if you damage it or its elements, FaceID is also disabled.

Poor repair

One of the conditions for FaceID to work is a native camera, therefore, if it is replaced, FaceID stops working and cannot be restored.

If all else fails, how to reset Face ID?

If the iPhone has become very often mistaken when recognizing a face, requires entering a digital password and practically does not recognize you, you need to try the graying:

How to make Face ID work better on iPhone?

There are several recommendations from both Apple employees and power users that can seriously improve the scanner’s performance.

Don’t use cheap screen protectors and glass

In most cases, any protection covering the front of the smartphone will not affect the operation of Face ID at first.

After a certain time, inexpensive films and glasses can peel off, peel off or slightly detach from the screen. This can lead to distortion of the infrared signal from the sensors and poor sensor performance.

Wipe down the front of your iPhone periodically

A banal advice, but it is the correct cleaning of the front panel that is the key to good work of both the Face ID scanner and the front camera of the device.

Hold iPhone 30 to 50 cm away from your face

It is this range that is recommended to use for the fastest possible sensor response. Do not bring the device closer to your face or move it to a fully extended arm.

Take off glasses or other accessories

Some users face Face ID issues when trying to unlock their device with glasses. The problem lies in UV protection. Certain models may not transmit infrared radiation, as a result, the iPhone does not find some important points on the user’s face and does not unlock.

Sometimes scarves, neckerchiefs and bandanas that cover part of the face interfere with the operation.

Change the angle of your iPhone

It is not necessary to painfully wait until the scanner makes several unsuccessful readings and you have to manually enter the unlock password. Gradually raise the iPhone DO eye level and align it parallel to the plane of the face.

Changes its position relative to light sources so that as little direct light rays as possible fall on the front surface of the smartphone.

Disable attention recognition

You can customize your iPhone so that it does not require the user’s direct attention to the screen to unlock. It is enough to show your face to the scanner, but not to look at the gadget to trigger the sensor.

Of course, this slightly reduces protection, allowing, for example, friends to unlock the gadget using the sleeping owner. In practice, this disabling reduces trigger lag and minimizes Face ID errors.

Face ID has a number of limitations

First, you should remember the limitations of this unlocking method and its features.

First. Face ID only works in portrait orientation

Only the new iPad Pro tablets are able to recognize the user’s face in both vertical and horizontal orientation of the gadget. To trigger the sensor on the iPhone, you need to keep it as level as possible. Minimal lateral deviations are possible, but with strong ones the sensor may not work.

This also applies to unlocking the iPhone lying on the table. The device needs to be raised, directing the screen towards you, and not trying to look from above, exposing the chin and lower part of the face.

Second. Face ID sensor doesn’t work when hit by light

Strong lighting or direct sunlight striking the sensor from behind the user’s head may prevent the scanner from correctly recognizing a face. This is possible when light hits the screen at a certain angle.

Third. Face ID can sometimes just turn off

This happens for security reasons in a number of predefined scenarios. For example, if the face is incorrectly read five times in a row, when you restart your smartphone or activate SOS mode.

If the iPhone has been left unlocked for too long or Lost Mode has been activated on it, the scanner will also be turned off.

Face ID will work immediately after unlocking iPhone with a password.

Fourth. The scanner needs to see the user’s eyes, nose and mouth

It is on these main points that a complex lita mask is built, which serves as a key for unlocking. All kinds of accessories can cause the gadget to work poorly.

Reconfiguring Face ID

Go to Settings. Face ID and passcode, enter the unlock code for the gadget and disable the scanner using the Reset Face ID option. We turn it on again and rebuild the sensor.

iPhone X Face ID Not Working Repair | Move iPhone a Little Lower/Higher

Sometimes re-tuning solves problems with frequent sensor failure.

Adding an Alternate Appearance

As users previously added multiple fingerprints for one finger to Touch ID, you can add a second portrait to Face ID.

Just open the Settings section. Face ID and passcode. Alternative appearance and scan your face again.

It is better to ask a couple of faces with all possible differences: with glasses and without, before and after piercing, clean-shaven and with a thick beard.

Why Face ID won’t work and how to fix it

One of the most technologically advanced features in modern iPhones is the TrueDepth module. This is the same “monobrow” above the display, into which the camera, light and proximity sensors, an IR emitter, a similar sensor and a dot projector were placed.

Together, all this stuffing is the most advanced face scanner in a mobile device. None of Apple’s competitors have come close to this solution so far.

Unfortunately, the module does not always work correctly and may crash. Now let’s figure out how to fix the situation.

Why Face ID failed

So, how did my iPhone come to such a life that it doesn’t want to see me now? Everything to the point of being banal is simple. this morning I was fed up with a ladder. Sorry, but another word is hardly suitable here. At the same time, the phone was in the right of his pants.

I landed successfully on the stairs but without fractures. I got off with a couple of solid bruises below the elbow and above the knee well, Face ID ordered to live long.

Apparently, during the 2-second flight, the iPhone hit the stairs, which slid out from under me. Although there is no damage on it, and in the case I always had it.

But the result is still sad. now every time I want to set up Face ID, the message “Face ID is not available Try to set up Face ID later” appears on the iPhone screen.

What conclusion can we make? If you unsuccessfully drop or hit your iPhone X, there’s a good chance Face ID will simply stop working. Why this happens. we will discuss below.

Physical malfunction of Face ID

What exactly could go wrong with Face ID? And here is already HZ. To create a three-dimensional model of your face, the TrueDepth system is used, which consists of sensors and emitters (point projector, IR camera, IR emitter). It is difficult to say what exactly failed on impact.

I’ve searched through many forums and articles about Face ID not working on iPhone X, but I haven’t found a concrete answer yet.

It was possible to find only scraps of information that hint in which direction to dig at all. It turns out the TrueDepth camera is somehow connected to the telephoto lens (the one on the bottom) of the rear camera.

Apple even updated its Face ID troubleshooting routine for Genius Bar employees, where it clearly stated “The first step in troubleshooting Face ID is to try to replace the rear camera module.” If this does not help, the iPhone is replaced with a new one. Even Apple gives up.

From my personal observations of my iPhone X with a faulty Face ID, I can note the following:

  • Camera apps take 3-4 times longer to load than usual
  • The rear camera works seamlessly. And both lenses. All functions (portrait, slow-mo, etc.) work.
  • The front camera works, but Portrait mode no longer blurs the background. Apparently Face ID sensors are involved in determining the contour of your body.
  • During a FaceTime call, the front camera does not turn on and the message “Camera is being used by another application” appears on the screen.
  • The flashlight (the one built into the rear camera module) now lives its own life. In most cases, it will not turn on when asked. But it can make an exception and light up

The above makes me think that perhaps the problem really lies in the rear camera module. Maybe the plume has moved away slightly, or something has broken off inside the camera itself.

All other phone functions are working properly.

Face ID software problems

If you did not drop or chop nuts with your iPhone, then the problem may be related to the software. We all know that software is designed to freeze and fail. If this is your case (and even if not yours) try the following steps:

  • STEP 1. Go to Settings. Face ID & Passcode. Reset Face ID
  • STEP 2. Hard restart your iPhone by pressing Volume down one by one. Volume. then press and hold the Side button until the screen turns off.

After your device restarts, try setting up Face ID.

If Face ID became unavailable after installing an iOS update, most likely the firmware is “crooked”. The most correct solution would be to connect your phone to your computer and restore it via iTunes with the latest version of iOS installed. If you need instructions, see here.

Unfortunately, in my case, these manipulations did not help, as well as Reset All Settings and Soft Restart. But it should be clear to a hedgehog that after the fall / impact, something inside the iPhone is out of order.

What to do when Face ID is not available

Contact the Apple Store for warranty. And this, in my opinion, is the best way out of this situation. Unfortunately, it is only suitable for iPhones that are still under warranty (usually 1 year). You can check the duration of the warranty by the serial number of the iPhone here on this page.

If your city does not have an official Apple Store or an authorized Apple service representative, the iPhone can always be sent by mail. To do this, you need to contact support (by phone or via chat) and agree to send the device.

What’s more, Apple will provide you with packaging materials and pay for round trip shipping (this should work in most civilized countries).

This is exactly what I did with my iPhone X, which stopped working with Face ID. A friend of mine helped me get in touch with people who provide services for the delivery of defective iPhones from Ukraine to Warsaw. Because the phone is still on the way, I don’t know how it will end. As soon as something becomes clear, I will definitely update the information in this article.

Contact your local workshop. This is a lottery. The problem with unavailable Face ID is not yet well understood. All that general craftsmen can do is check the cables and all internal connectors. If they start swapping modules or individual Face ID sensors, things could get worse. This is usually the case.

Chinese craftsmen have found that the main components of Face ID (IR camera, dot projector and IR emitter) are unique to each iPhone, because tied to a specific motherboard.

From this it follows that the usual repair on the knee is unlikely to work here.

Dropped iPhone X. Face ID is no longer available [Solution]

For a long time I was trying to write an article where I would describe possible problems with Face ID on the iPhone X, XS, XR and their possible solutions. But somehow everyone lacked the experience and desire to seek information. And today, without expecting it, I faced this problem “face to face”. Surprisingly, this word turn has a double meaning here.

Today for the first time I saw on the screen of my iPhone the following message “Failed to activate Face ID on this iPhone”, and when I tried to re-configure everything. “The Face ID function is not available”. It’s a shame, damn it! But let’s talk about everything in order

Face ID not available still!

Of course, without Face ID, the iPhone X does not “turn into a pumpkin”, but it is no longer so convenient to use it. Every time you pick up your iPhone, you have to enter a numeric password. And in the online banking application, you also have to remember passwords. But remember. THIS IS NOT THE BIGGEST PROBLEM IN LIFE!

You can still use such a device. Alternatively, you can sell this iPhone at a “sweet price” and buy yourself a new XS.

I, in turn, thank God for taking money, not health. The main thing is that the arms and legs are intact.

Write in the comments what led to the breakdown of Face ID in your situation. Share your repair experience, even if it was unsuccessful. I hope that soon an UPDATE will be added to the article with the result of repairing my iPhone X.

UPDATE My phone was delivered to Warsaw Apple Store. This is done by people who make money on it. The price of the issue is about 30-40. The most important thing at this point is that the iPhone has been successfully adopted by a tech worker. Apple support. This means that back I have to get a fully working iPhone.

At the same time, I want to remind you that I did NOT send either a check or a box with the phone. Actually, I never had a check. A little more than a month has passed since the dispatch.

UPDATE According to the latest data, the phone has been replaced with a new one. So Apple could not fix the problem with Face ID.

UPDATE After 2 months, I received a completely new iPhone X with exactly the same parameters as the previous device (the iPhone serial number naturally changed). The phone came in a film, wrapped in a soft envelope, without any accessories. The phone had a paper from iSpot (Apple’s official distributor in Poland).

Finally, I’m back with the iPhone. I won’t say that 2 months with the Galaxy Note 8 was a torment, but the iPhone is somehow more pleasant to use.

The experience gained above suggests that sometimes even Apple cannot fix a problem with Face ID, namely the state of the phone when “Face ID is not available”. This is why they just change your broken phone to a new device.

If you find yourself in a similar situation, contact an authorized Apple representative and if everything is OK, your device will also be replaced.
