Hello community,
example from

Device Administrator library

Starting from Android 2.2 (api level 8), Android allows application to be registered as administrators. Administrator apps have the following special features: - Manually lock the screen - Set the minimum password length and quality - Wipe the entire device - Set the maximum allowed time before...

works nicely. I need it only for device locking, so ignoring other errors.
It is able to lock a device. However, when pressing power button, I can not use a biometric to unlock a device. Is it a library limit, like library doen't support this, or is it a bug, or am I missing something?
Device: samsung flip 7
Android: 16

Thank you for your time.

you need to configure your device to use biometric for unlocking by yourself.
The library can not change any android settings beside this

- Manually lock the screen
- Set the minimum password length and quality
- Wipe the entire device
- Set the maximum allowed time before the device locks
- Request the user to change password
- Manually set a new password
- Disable the camera
- Track password changes
- Some other security features as described here.
