How do you apply a glass screen protector with a fingerprint scanner under the screen?
Compatible with fingerprint scanner
Not all screen protectors work well together with a fingerprint scanner. Due to the material and the thickness of a screen protector, you might not be able to unlock your smartphone with your fingerprint. This is often the case with glass screen protectors. In the specifications on the product page of your screen protector, you can see if it's compatible with a fingerprint scanner. If that's not the case, the steps in this article sadly won't work. That's why you should always check if a screen protector is compatible with a fingerprint scanner when you're looking for one.
