Facial recognition It is one of the characteristics that, today, we can find in any mobile device that is current. In addition, it has become one of those functionalities that users use the most to be able to easily unlock terminals without having to enter any kind of password. And that’s not all, since it can be used when we wear the mask, but you have to configure it in the correct way.
Despite being one of the methods that most facilitate the daily use of our smartphone, it continues to give different problems that, to more than one user, is a real headache. Since it is quite common that it stops working for no apparent reason or that it does not even detect our face well. For this reason, we will show you all those most common errors and the possible solutions that will put an end to these annoying errors.
Errors when unlocking the mobile with the face
There is no doubt that one of the most comfortable functionalities that we find in our terminals to be able to unlock the mobile is facial recognition. One of those options that we find in practically all terminals for a while.
However, many of the smartphones, whether of one brand or another, have various problems recognizing our face, causing us to resort to entering a pattern or a pin. Even without working, losing even more time than we expected. down the road a long time. So that this does not happen to you, we are going to give you all the keys.
Unlock does not detect face
On many occasions, this method to unlock our terminal stops working for a simple safety measure. So we will have to use another alternative, either by unlocking with PIN, Pattern or password.
But, if after doing it with that alternative we still have this same error, we can try the following. We will have to take the mobile and put it firmly, in a vertical position in front of our face, approximately 20 centimeters away. In order to fit as tightly as possible so that it unlocks easily.
Dirty or damaged sensor
Another aspect that we must take into account is that, in the front camera or sensor that is used for said facial recognition, there may be some dirt. Something very simple, but that can be a key factor that prevents its correct operation since, if this sensor is dirty, it may continually see the user’s face when entering.
So we will have to check if this is our case, well it will be necessary to clean it, so that it works normally again. However, if we clean it and it continues to fail, the problem may be that the sensor that handles this is completely damaged. It could have been from a fall, since the blow will have damaged it in such a way that it is impossible for it to perform its function. So we will have no choice but to take it to a technical service so that it can be repaired.
It does not allow to configure it
One of the most important aspects when configuring this functionality is that the simple fact of having a certain screen saver could be making it difficult for us to definitively carry out said configuration. So the solution will be simple, since we will only have to remove said protector from the mobile panel.
Or even, when placing it, we could have completely covered said sensor, so we will have to make sure that it is well placed and that it is also compatible with our mobile. In addition, when putting the facial unlocking, it is most recommended that, if we wear glasses on a regular basis, we would have to do it with this element on.
Methods to fix facial recognition
Although with the passage of time and the evolution of technology we have been changing fingerprint readers for this type of unlocking and its great continuous improvement. This system is not perfect, although it offers us a quick unlock, it can fail in different ways. Luckily, there are different ways to solve various problems that this method can cause us.
Update the terminal
There is no doubt that our devices have great technology, but sometimes if we go a long time without updating it, it could cause some kind of error to appear. And it is that an update is usually in charge of introducing new functions in our phone, with which we can also solve those errors that arise from one day to the next, as is the case that we present today.
So if facial recognition stops working or you have different problems, the easiest solution is to update your mobile device. Since, surely, it is the easiest way to fix it. In the event that you do not have any type of update, you will have another manual solution, which fixes many problems. We refer to restarting your mobile device. Therefore, it is possible that when it has started again you will be able to unlock the phone with your face again.
Try other lighting
One of the ways to solve the fact of unlocking the phone using our face, will be to have a light that is correct. Since for the terminal sensor to be able to recognize you well, it will need a certain illumination. That is, if we are in a too dark place or your face is not seen properly, it will be practically impossible for the device to be unlocked using this functionality. Therefore, make sure the lighting is adequate when using this method.
Restore your mobile
In the event that the above methods do not work for you, we will have to suspect that the failure for which facial recognition it does not work is from the smartphone itself. Also, it could be a software failure, so resetting the terminal is something that could help us solve this common error.
Therefore, if none of the previous solutions has worked for you, you can make the mobile device return to its original factory state. Although, we must bear in mind that it is one of the last methods that we will have to try. Likewise, we recommend that you make a backup copy so that you do not lose anything from the terminal. The steps to accomplish this are as follows:
- Open Settings> System. Although in some layers of customization you will have to enter the Security section.
- Go to Reset> Reset phone and click on that button.
- It will ask you for the security key that you usually use and then click on confirm.
How to improve it on your mobile
One of the first options that you could have in your terminal, since each brand offers different ones, will be to see if in our mobile we have a function that allows us to have a faster recognition. And it is based on artificial intelligence in order to take much less time to accept or reject access.
The best of this option allows us a higher speed to unlock our terminal. However, it must be clear that we will also have somewhat less security. But, if this does not matter to you, you can activate it if you have it. Otherwise, nothing will happen if you have to wait a few more tenths of a second.
Another feature that we can have in our terminal, and that helps us make this functionality go better, is to temporarily increase the brightness of the screen when we are going to use this function. This effect will occur whenever we are in low light situations, at which time many mobile devices fail to recognize us. Therefore, with the help of the automatic brightness of the smartphone screen, we will get enough information from our face to make it work.
