Fairphone 4 locking because of too many fingerprint attempts while picking up the phone
- /e/ version:
- Device model(s):
- Device rooted: yes/no
Summary
Often Fairphone 4 , scans too many times quickly and shows "Too many attempts. Try again later" When the fingerprint sensor is touched , for example while picking up the phone.
The problem
Steps to reproduce
I found that the easiest way to reproduce is, to touch the fingerprint sensor to the middle of your palm. Otherwise when using non recorded fingers, not every time the multiple scans are done.
What is the current behavior?
Phone scans quickly many times when the sensor is touched.
What is the expected correct behavior?
Fingerprint sensor should not scan multiple times quickly. There needs to be a delay between scan attempts.
