Face unlock not working? Here’s how to fix it

It was quite a long time before fingerprint scanners appeared on the low-end market. But it didn’t take long for the face unlock feature to hit the budget phone market, with phones like the Vivo V7 Plus, which costs $ 300, and others like the Huawei Honor 7X and Honor 9 Lite, soon to be. via an OTA update.

This means that you don’t have to shell out $ 1000 to buy the Samsung Galaxy Note 8 or even half of it for the OnePlus 5T in order to enjoy the beauty of facial recognition. Given the price differences between, say, Honor 9 Lite and Samsung Galaxy Note 8, the face unlock feature on the former isn’t nearly as impressive as the one you get on the latter. As a result, you may encounter some problems along the way, but this is not to say that those who use Apple’s Note 8, OnePlus 5T, or even iPhone X, will not encounter problems of their own.

So what should you do if face unlock is not working on your Android phone?

The basics

Those sensors surely need a cleaning (intentionally overdone, by the way!)

First, let’s get to the basics. In most cases, you will find that the reason why face unlock is not working on your Android phone is your own fault. So, to make sure it’s not you, make sure of that:

  • The front camera, which is used for facial recognition, is not covered by anything, be it a screen protector, a case, or even dirt (if you bought a new screen protector recently and run into problems after applying it, then this could be the case).
  • Since the face unlock function works by scanning your face (eyes, nose and mouth), make sure it is visible to the front camera.
  • Although the face unlock feature of almost all phones is designed to work in almost all conditions, even when wearing glasses or in dimly lit rooms, there are some sunglasses that block light and therefore can prevent that the face unlock function works properly. Also, try to use the function in well-lit environments for the best results. – Taking off the glasses always helps to unlock the face.
  • Speaking of which, when you are outside on a sunny day, make sure you hold your phone so that the sun and the scanner are not in direct contact.
  • To get the best out of face release, make sure the phone is in the portrait orientation. As mentioned above, also make sure to face the camera and keep the phone closer to your face, perhaps an arm’s length away.
