I suddently noticed that I need 2-3 attempts to unlock phone with fingerprint reader. It happens after phone is idle for 1+ hours.
I created finger scans from scratch but this did not resovled the issue.
I entered service mode: *#0*# - then SENSORS - Finger print reader - run the test
These are test restults: https://imgur.com/a/gXX1dMd - same each time i press and hold finger for 5 secons
What is odd, I run test on S8 and S7 with even worsed results
What are your test results?
