Did it work before? Mine not working since Oreo 8.1, Pie 9.0 until now Android 10 Q. So it is the limit in the hardware itself. I am using Redmi note 5 Whyred, custom ROM Havoc 3.0 Android 10 Q.

If you have root at your current device, you can use trigger Command output

Code: Select all

logcat -c; logcat -v time *:D
Try this first in terminal emulator, and then touch the fingerprint to see what event it trigger. Use it as the filter. Example, at mine, everytime fingerprint is touched, it is

Code: Select all

: report_input_event - Reporting trigger_code=65537, event type: 1, code: 96, value:1

It seems certain fingerprint sensor doesn't give all the event to the OS, hence not detected by Automagic. Mine is fpc brand. Maybe yours also the same. You can look at it at the logcat, after you plug to the PC, use adb shell logcat.

If the trigger not working and you have no root, then you need to wait for AM 1.38, where we got permission read log without having to root the phone.
