How to unlock the phone if I forgot the password through an emergency call

A modern smartphone has an advanced protection system that avoids access to it from third parties. Such protection includes various locking methods that cannot be removed without a password knowledge. The same password can become a significant obstacle for conscientious users who bought a phone on the flea market, and later faced with blocking the screen of the acquired gadget. Different ways will help to do this. In the article, consider how to unlock your mobile phone, if you suddenly forgot the password, through the function of an emergency call.

If you put the screen lock on your phone, then on the screen of the PIN code (graphic key) in the lower part of the screen, the emergency call button is usually displayed. This button allows anyone to take the phone to dial 911 in the case of an emergency, without the need to enter a pin code or a graphic key.

On most Android devices, the Emergency Call button (Emergency Call) opens only the panel for recruiting. However, on many old phones and early versions of the Android OS, when this button is pressed, there is an automatically a call to 911, or just number 911 will automatically appear in the list of rooms for calling.

Social methods for unlocking a mobile device

In addition to purely technical, there are other ways to find out or overcome the PIN code, or graphic code (pattern) of the screen lock. In some cases, social methods can be more effective than technical solutions and help in unlocking devices before which existing technical developments are grazed.

This section will describe the methods of unlocking the screen of the mobile device that do not require (or require only limited, partial) the use of technical means. To perform social attacks, you need to study the psychology of the owner of a blocked device as deeply as possible, to understand by what principles it generates and retains passwords or graphic patterns. The researcher will also need a drop of luck.

When using methods related to the selection of password, it should be borne in mind that:

  • With the introduction of ten incorrect passwords on Apple mobile devices, user data can be erased. It depends on the safety settings that the user installed;
  • On mobile devices running the Android operating system, Root of Trust technology can be used, which will lead to the fact that after the introduction of 30 incorrect passwords, the user data will either be unavailable or erased.

Re.ask password

This will seem strange, but the unlock password can be found out by just asking the owner of the device. As statistics show, approximately 70% of mobile devices willingly report the password. Especially if this reduces the time of research and, accordingly, the owner will receive his device faster back. If there is no way to ask the owner’s password (for example, the owner of the device died) or he refuses to open it. the password can be recognized from his close relatives. As a rule, relatives know the password or can tell you possible options.

Protection recommendation: Password from your phone is a universal key to all data, including payment. Speak, transmit, write it in messengers is a bad idea.

Look at the password

The password can be spied at the moment when the owner uses the device. Even if you remember the password (symbolic or graphic) only partially. this will significantly reduce the number of possible options, which will allow you to quickly choose it.

A variant of this method is the use of video surveillance chambers on which the owner is captured, unlocking the device using a graphic password [2]. Described in the work “Cracking Android Lock In Five Attempts” [2] The algorithm, by analyzing videos, suggests a graphic password and unlock the device for several attempts (as a rule, you need to make no more than five attempts). According to the authors, “the more complicated the graphic password, the easier it is to choose it”.

Protection recommendation: Using a graphic key is not the best idea. It is very difficult to peep in a digital-letter password.

Find the password

The password can be found in the recordings of the owner of the device (files on the computer, in the diary, on fragments of paper lying in the documents). If a person uses several different mobile devices and there are different passwords on them, then sometimes in the battery compartment of these devices or in the space between the smartphone housing and the case you can find shreds of paper with recorded passwords:

Protection recommendation: no “Notepad” with passwords should be kept. This is a bad idea, except when all these passwords are obviously false in order to reduce the number of attempts to unlock.

Smudge Attack)

This method allows you to identify sweat traces of the hands on the device display. You can see them by processing the device of the device with light dactyloscopic powder (instead of a special forensic powder, you can use a baby powder or other chemically inactive fine powder of white or light gray color) or looking at the device’s screen in the shining rays of light. Analyzing the mutual arrangement of traces of the hands and having additional information about the owner of the device (for example, knowing his year of birth), you can try to choose a text or graphic password. This is what the sweaty layering looks like a smartphone display in the form of a stylized letter Z:

Protection recommendation: as we said, the graphic password is not the best idea, like glass with a bad oleophobic coating.

Artificial finger

If the device can be unlocked by fingerprint, and the researcher has samples of the hands of the owner of the device, then on the 3D printer you can make a three-dimensional copy of the owner’s finger and use it to unlock the device [3]:

For a more complete imitation of a life of a living person-for example, when the sensor of the fingerprint of the smartphone still detect heat-the 3D model is worn (leaned) to the finger of a living person.

The owner of the device, even forgetting the password of the screen lock, can unlock the device itself using the imprint of his finger. This can be used in certain cases when the owner cannot report the password, but, nevertheless, is ready to help the researcher to unlock his device.

The researcher should remember about the generations of sensors used in various models of mobile devices. Old models of sensors can work almost on the touch of any finger that does not necessarily belong to the owner of the device. Modern ultrasonic sensors, on the contrary, scan very deeply and clearly. In addition, a number of modern sub-screen sensors are just a CMOS photocamers that cannot scan the depth of the image, which is why deceiving them is much easier.

Protection recommendation: if a finger, then only an ultrasonic sensor. But do not forget that applying a finger against your will is much easier than a face.

“Verily” (Mug Attack)

This method is described by British police [4]. It consists in hidden surveillance for the suspect. At the moment when the suspect unlocks his phone, the agent in civilian clothes pulls him out of the owner’s hands and does not allow the device to be blocked again until the experts are transferred to it.

Authorization during the call

Another way to remove the request for confirmation of the Google account is to tie another account directly during the incoming call to the phone. You can do this in a couple of minutes. faster than to go through the IMEI restoration procedure. To get around the request, the user will need:

Important: at the stage of creating an account or entry into an existing call, you can complete by pressing a “reset” on the smartphone from which it was carried out.

The third way to remove the graphic key in the incapaciter is to reset the settings

Here, first, there may be difficulties with the selection of the correct combination of keys for entering the menu.

Turn off the phone, and then click simultaneously click the buttons “Nutrition” and “Sound” and “Main button”.

If you enter the menu, so does not work out other options, there are some of them. Power button and enlarge (sometimes reduce) sound (without a homemade button). In a word, you should see the menu as below.

Then the button to reduce the volume move to the “Wipe Data/Factory Reset” item and click the “VKL” button.

Confirmation will appear. we move to the “Yes” and also press “.

Now the last step is rebooting. She is at the first paragraph. This is “Reboot System Now”.

Choose it with a power button. All. The device will reboot. Device like from the head. Rejoice. Congratulations.

Now you can completely turn off the graphics key or put another.

This method of hacking a bad defense is only that the data is lost, but if the phone is blocked, then which one is a good.

This is the first, and the second, if everything would be simple, then why would you need the protection of the phone as an incinerator with a graphic key? Success.

Forgot the password from the phone. What to do

If the opportunity to use the smartphone unlock through the Find My Mobile and Find My Device for some reason is not, you can use a standard reset tool. He, like the search service for a lost smartphone, involves a complete rollback to factory settings with a concomitant password discharge, so in both cases the result will be the same. you will lose all the data, but you can establish a new password.

You can drop the password with regular tools directly from the settings

  • In the window that opens, find the section of reset and restoration of backup copies;
  • Select a complete discharge of data and confirm the rollback to the factory settings.

A year ago, it was difficult to think that many well.known foreign services would temporarily leave Russia. If this happened 7-8 years ago, then for users it would probably have turned out to be a disaster: there were no domestic analogues or they were not developed as well as now. Fortunately, in 2022, almost any application from Google, Microsoft and other well.known software suppliers can be replaced by a Russian counterpart. These services have been tested by time, convenient and have been working well in Russia for several years: they also have their advantages, and getting used to them will not be difficult. We understand how to replace Google services and other applications that no longer work in Russia.

Despite the fact that due to the fall in the ruble in Russia there are almost no truly cheap smartphones, something else can be chosen. If you open the website of any trading network, you will see that there are still devices for 10-15-20 thousand. At worst, you can go to Aliexpress and buy something inexpensive on the site that does not pay VAT and does not have additional expenses at all, except for direct shipping. But you should not rely on the availability of smartphones, because it can turn into big problems for you. And the brand as such here is almost no.

The function of tracking the location in the smartphone has long become the subject of a large discussion. With the introduction of the function of a mandatory request for resolving access to geolocation in certain applications, users increasingly began to ask the question: is it worth it to include it at all? Here, the owners of smartphones were divided into two large categories: some completely turn off all such functionality, others simply do not pay attention to tracking. Today I propose to figure out which of them is right and once and for all put an end to this issue.
