I thik it's need an update.it is still in android version 9.
Why are you on Android 9?
But I have same issue on 11. It works awful. Maybe something wrong with my fingers?
If it's happening on both A9 and A11, it might be the sensor itself. Have you tried taking it in to be inspected?
I periodically wipe the sensor from dirt and dust. This helps it to work correctly.
Is anyone knows the code for factory tests? There is calibration tool should be there. Maybe that's the solution.
How you do that?
You mean bring it to service?
Unfortunately I have no any authorized in my region(
