Fingerprint sensor

Is anybody having problems scanning their fingerprints on S21? Mine keeps telling me to make sure finger covers sensor

Hi Risky, removed plastic film and factory protector when I got a new screen protector

Hi Steve, I cleaned the screen & trying to register fingerprint whilst indoor

Glass screen protectors do not work with under screen fingerprint sensors. You will need to use a plastic flimsy type.

Husband has a plastic one and it won't work on his either 😒

Oh, that is odd! Think your only option is to take it back to where you purchased the phone from.

I will contact them & see what they say 😏

Did you try it before removing the factory fit screen protector? It sounds to me like your screen protectors are disrupting it. Light has no relevance as the sensor uses ultrasonic waves to register its impression.

[CazGall]

Yes

If you go to the Samsung members app and click get help, phone care, run the interactive checks and click fingerprints. Does it not register there? If it fails to register, you will need to get the unit repaired or replaced.

Thanks, I'll try that 👍👍
