After i updated to Android 10 the fingerprint button don't appears with the screen off, only on lock screen and other apps...
I see other users with the same problem so here is how to make the button appears with screen off again!
This doesn't fix for completely the problem but the fingerprint button will works with screen off again.
First of all you need to check if the "show fingerprint icon when the screen is off" option is turned on.
For that you need to go on settings/security/fingerprint and check that.
After that go to settings/display/advanced/lock screen display and turn on "new notifications"
That is it!
Now with the screen off just do a double tap on the screen to appear the fingerprint icon.
I hope that can help you.
Please comment below if that works for you.
