Fingerprint always pop up "No match"

[User101]

This problem was there from the day I have bought this phone(Galaxy M21), I couldn't fix it because of lockdown. Whenever I press power button to turn on the phone, it always pop up No match statement in the bottom. It automatically keeps checking for the fingerprint even i haven't put my finger on the sensor. Later on if I do not open phone then it will start giving me timer that try after 30 seconds too many attempts. User experience is getting very annoying due to this.

If someone have faced similar problem or fixed it then please help me out.

screen protector is there on the screen but there is nothing near to fingerprint sensor

Try removing the screen protector and use it , if the problem persists then reach out the service centre..

Ur an **bleep**, m21 does not have In display finger print sensor, it's a physical one at the back of the phone, what is screen protector or any other guard got to do with it, stop giving wrong /bad advise
