Causes of problems

Talking about the appearance of a sensor problem, you can identify some cases that are conducive to problems. The main part relates to the settings inside the phone.

  • The sensor function is disabled;
  • Activation of unnecessary options;
  • Incorrect film or protective glass. Operation may be impaired if there is no special hole on the glass or film for the conversation speaker or the front camera. In such a situation, you just need to change the protective material.
  • Incorrect operation of the device itself. Only in this case it will be necessary to calibrate the sensor.

Now let’s deal with each case separately.

If Calibration Doesn’t Help

There are times when calibration doesn’t help. The reasons may be as follows:

  • Problems with the firmware, to fix which it is worth reflashing the device
  • Perhaps after the repair, the display was replaced with a non-original one.
  • A banal marriage. in this case, you need to go to the service center or to the seller

For clarity, we recommend that you look

The proximity (light) sensor on Xiaomi is responsible for automatically adjusting the brightness, as well as turning off the display during a call. Failure to work can cause a lot of inconvenience, for example, the display may stop turning off during calls, which will lead to accidental presses, as well as increased battery consumption. The issue can be resolved by calibrating the proximity sensor.

The reasons for the crashes can be different, so the first thing to do is to restart Xiaomi. If this does not help, then let’s look at the options for solving the problem from the simplest to the most complex:

Where is the proximity sensor on Xiaomi

Many users of Xiaomi smartphones are faced with various malfunctions in its operation. One of these is a malfunction of the proximity sensor, which suddenly ceased to function normally. Namely, the proximity sensor does not work. At the same time, this situation can be, both in old and in new devices, in the same Xiaomi Redmi Note 7. To perform any actions with this element, you need to know where it is.

Typically, the proximity sensor on Xiaomi is located at the top of the phone, above the screen. Accordingly, when the device is brought to the ear, the access of light to it is blocked, which is why it turns off the backlight of the screen. The phone itself continues to work normally. When the luminous flux again falls on it in normal mode, the backlight turns on again.

Considering that this is an additional element, different breakdowns are inherent in it. Quite possibly:

Mechanical damage as a result of falling or other careless actions.

Software glitch, for example, after incorrect updates, but, as a rule, they do not touch the proximity sensor.

After unsuccessfully making changes to the settings by inexperienced users.

The problem would be unimportant if the sensor was not activated even when typing an SMS message. This most likely indicates incorrect settings or excessive sensitivity. First you need to convince whether the sensor is working or not. If it is turned on and does not react to obstacles in any way, then it probably needs to be physically replaced. You can activate it in the smartphone settings in the “Calls” item. But do not forget to turn off the lock function in the. because when they are both activated, failures often occur.

If the sensor on Xiaomi is turned on and works randomly, or does not work at all, then you should try to configure it. This can be done in a special service menu, which can only be accessed by rebooting the phone. Accordingly, you need to turn it off and turn it on by pressing the volume up and power buttons. In the menu that opens, select the “PCBA test” item. To start it, you need to click on the “Calibration” button. It is important to place the smartphone on a perfectly flat surface, and so that the sensor does not cover anything, blocking the sun’s rays.

When the quality of the pixels is determined, and among them it was possible to find “burnt out”, you can start looking for applications that will correct the situation:

  • JScreenFix is ​​easy to use, you need to use the Fix Stuck Pixels button to get started. The developer promises 30 minutes to complete this operation, but the service center masters recommend leaving the devices. Not less than 10-12 hours for a more complete check;
  • Pixel Fixer: Another program similar to JScreenFix. To restore pixels, you also need to click on the green button;
  • Dead Pixel Treatment: The platform does more than test a mobile phone for dead pixels. And then “heals” them, but at the same time reveals other defects in the display.

When using applications, it is recommended that during the “treatment” the device does not disconnect it from the chargers. The smartphone is always on during pixel processing, so the charging may not be enough.

Microcracks of the screen are fraught with a break in the power circuit. If this happens, then you will have to change the screen. Fortunately, in China, they are several times cheaper.

It happens, and the malfunction lies in the incorrect installation of the SIM card or flash drive. Try to take them out and check what will happen.

A map with problems can be repaired by restoring broken clusters using a PC.

If shaken, a poorly positioned plug from the display may fall out. What will entail the disconnection of the image transmission module, or partial disconnection.

Remove the cover of the device, and plug the ribbon cable into the socket. If it is inserted, take it out and insert it. In this case, do not forget to disconnect the power cable from the battery.

Proximity sensor problem in Xiaomi phones is spreading

Recently, the problems that have arisen in Xiaomi terminals have given many reasons for conversation, among other things, by discovering software errors that MIUI 12.5 is trying to solve in the best possible way. However, there is a problem that even the latest version of the layer cannot solve, and this is the proximity sensor.

How to Enable or Disable Proximity Sensor in Redmi Note 7 Pro(MIUI 11.0)?

Several high and mid-range Xiaomi terminals have been affected by this glitch, and even Xiaomi itself does not know how to solve it. Complaints on social networks and in various forums do not stop appearing, and decisions on this matter are not taken. In other cases, we saw similar glitches with the proximity sensor from other manufacturers and models, but they did not last long.

What is happening and which mobile phones are affected?

A glitch that occurs, for example, when it is necessary to resort to the proximity sensor during calls, causes the screen not to turn off or to constantly turn on and off while we put the mobile phone on our ear. It also appears when we carry a mobile phone in our. as well as when using sound, for example, using WhatsApp voice memos, where the proximity sensor goes crazy and constantly turns off the screen.

Although Xiaomi has not yet recognized this issue directly, it did so indirectly and in an attempt to find a solution, compiled a list of possible affected mobile phones with the following mobile models: Xiaomi Mi 10T, Mi 10T Pro, Mi Note 10 Lite Redman Note 10 and Redmi Note 10 Pro But based on our own experience and complaints that we have seen on the net, we can expand the list with several Redmi Note 9 and Redmi Note 8.

Finding Proximity Sensor Solution in Xiaomi

After the company has seen so many complaints, the list of Xiaomi mobile phones with sensor issues that the company has prepared includes a link to a survey in which it tries to find out in more detail what is happening with their devices. We can access the survey, that is, in English, and fill it out by answering questions such as, for example, at what time did we experience sensor failures. But something very curious that we can see in the review itself is that this sensor is constantly called “ultrasonic sensor”, which gives reason to many experts who have already confirmed that the mentioned models do not have a proximity sensor as such, and that’s where inconvenience.

Xiaomi has combined software with an accelerometer and an ultrasound-based sensor to achieve an imitation of a proximity sensor. We do not know if a solution will be found with this survey and some updates, but the truth is that despite this strange change made by Xiaomi, with the methods of fixing failures with the Xiaomi proximity sensor in some cases this is the case. You were able to calibrate the “sensor” and the problem disappeared. What we really hope is that in future modules this problem will go away if you change the technology used or optimize it properly.

Proximity sensor problems on Xiaomi: how to fix it

Our mobile phones are full of sensors that allow us to use them in almost everything, some of them are more important than others, but necessary in one way or another. Proximity sensor glitches on several Xiaomi phones that prevent us from talking on the phone normally.

Luckily for us, MIUI has options for everything we need, and we’ll have to resort to them if we want these mistakes to never happen again. This is not a specific model or only the Redmi brand and it means that many users have been affected, although from now on the error will not be repeated.

Problems with calls on Xiaomi

These problems are due to poor configuration, which does not fit by default in Xiaomi models. This causes the proximity sensor of our mobile located on top of the mobile phone to not perform its function. When making a call or receiving calls and bringing the phone to our ear, we will find that we hang up or accept some options without making sense.

It may take some time to find the error, as it will be very difficult for us to know if the screen is locked when we go to our ear. The best way to find out. make a test call to a relative or friend and use your palm to bring him closer to the top of the device while we are talking. In case the smartphone is not locked, we will have to follow the steps that we will show you.

Fix Proximity Sensor Error Using MIUI

In order to find the Proximity sensor error in Xiaomi that we are in the sections, we only need to go to the settings of our Xiaomi mobile, access the applications section and then touch the system applications. Among the options we will select “call settings”, and inside we select “incoming call settings”.

Once inside, we can find the option to activate or deactivate the proximity sensor, an option that has been fixed in recent MIUI 11 models but continues to cause problems on many devices. If we have the option, all we have to do is turn it off and then reboot the cell phone. Then we repeat the steps and activate it to make it work again.

Calibrate the sensor using the secret menu

In case that was not enough or the option did not appear in our model, we will have to resort to the secret of MIUI settings. To do this, go to the original Xiaomi phone application and type the following code without errors: # # #

Once inside, we move on to option 7 called Proximity Sensor Test. From here, we’re going to test the sensor by simply covering the sensor and checking how it changes based on light and distance changes with our hands. It is likely that we will not find any crashes, and in any case, it is recommended to report the error and fly back.

Now we need to touch the three dots in the upper right corner and click “Calibrate Proximity Sensor” to calibrate the mobile proximity sensor automatically. After the process is complete, we restart the mobile phone, and when we use it again, we must not find it annoying failure in Xiaomi that makes us miss calls.
