Facial recognition is one of the features that, nowadays, we can find in any current mobile device. In addition, it has become one of those features that most users use to easily unlock the phones without having to enter any password. And that’s not all, since it can be used when we wear the mask, but it must be configured correctly.
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, it is a real headache. Since it is quite common to stop working for no apparent reason or even not detect our face well. For this reason, we will show you all the most common errors and possible solutions that will put an end to these annoying failures.
Errors when unlocking the smartphone with face
There is no doubt that one of the most convenient features that we find in our phones to unlock the mobile is facial recognition. One of those options that we find in virtually all phones for some time.
However, many smartphones, whether of one brand or another, have various problems recognizing our faces, causing us to have to resort to entering a pattern or a pin. Even, without actually working, wasting even more time than we expected. along the way a lot of time. So that this does not happen to you we are going to give you all the keys.
Unlocking does not detect the face
On many occasions, this method to unlock our phone stops working for a simple security 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. Adjust it as much 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 used for such facial recognition, there may be some dirt. Something very simple, but that can be a key factor that prevents its proper functioning since, if this sensor is dirty, it may continue when internal see the user’s face.
So we will have to check if this is our case, as it will be necessary to clean it so that it returns to work normally again. However, if we clean it and it continues to fail, the problem may be that the sensor that is responsible for this is completely damaged. It could have been caused by a fall since with the blow it will have been damaged in such a way that it can’t perform its function. So we will have no choice but to take it to a technical service for repair.
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 hindering that we can perform this configuration definitively. So the solution will be simple since we will only have to remove the screen saver from the mobile panel.
Or even, when placing it, we could have completely covered the 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 placing the facial unlocking, the most advisable thing is that, if we wear glasses regularly, we would have to do it with this element on.
How to fix facial recognition problems?
Although with the passage of time and the evolution of technology we have been changing the fingerprint readers for this type of unlocking and its great continuous improvement. This system is not perfect, although it offers a fast unlocking, it can fail in different ways. Fortunately, there are different ways to solve various problems that this method can cause us.
Update the phone
There is no doubt that our devices have great technology, but sometimes if we spend a long time without updating it, it could cause some kind of error to appear. And is that an update is usually responsible for introducing new features on our phone, with which we can also solve those errors that arise from one day to another, as is the case that we present today.
So, if the facial recognition stops working or has different problems, the simplest solution is to update the mobile device. Since, surely, it is the easiest way to fix it. In case you do not have any kind of update, you will have another manual solution, which fixes many problems. We are referring to restarting your mobile device. So, it is possible that when it has started up again you will be able to unlock the phone with your face again.
Try another lighting
One of the ways to solve the problem of unlocking the phone using your face is to have the right lighting. For the sensor of the phone to be able to recognize you well, it will need a certain illumination. That is if we are in a place too dark or your face is not seen in the right way, it will be practically impossible to unlock the device using this feature. Therefore, make sure that the light is adequate at the time of using this method.
Restore your phone
If you do not get to work with the above methods, we will have to suspect that the fault by which the facial recognition does not work is the smartphone itself. In addition, it could be a software failure, so resetting the phone is something that could help us to solve this common error.
Therefore, if none of the previous solutions have worked, you can return the mobile device to its original factory state. However, it should be noted that this is one of the last methods to try. Likewise, we recommend you make a backup copy so that you do not lose anything from the phone. The steps to do this are as follows:
- Open Settings > System. Although in some customization layers 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 facial recognition and get best results on your mobile?
One of the first options that you could have in your phone 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 to take much less time to accept or reject access.
The best thing about this option allows us greater speed to unlock our phones. However, it should be clear that we will also have somewhat less security. But, if you do not mind this, you can activate it if you have it. Otherwise, nothing will happen by having to wait a few more tenths of a second.
Another feature that we can get to have in our phone, and that will help us to make this functionality go better, is to increase the brightness of the screen temporarily when we are going to use this function. This effect will occur whenever we are in low-light situations when many mobile devices fail to recognize us. So, with the help of the automatic brightness of the smartphone screen, we will get enough information about our face to make it work.
