Fingerprint-On-Display (FOD) is an on-screen fingerprint scanner that captures, registers, and verifies your fingerprints. You can use it to unlock your phone.
You need to first register your fingerprints by going to Settings > Security & lock screen > Fingerprint and follow the instructions.
To use it, wake the screen by quickly clicking the power button and place your registered finger on the indicator (fingerprint icon) to unlock your phone.
Note: If you want to use a screen protector, make sure it is an authorized and compatible screen protector. Use it when you register your fingerprints to ensure successful fingerprint recognition to unlock your phone.
