Android Question Detect activity of a user: screen on (and unlock if presents)

Have you tried PhoneEvents? I think that it will work as long as your app is running. You cannot intercept this event if your app isn't running.

PhoneEvents ineed work, thanks, Erel.

So the way is as usual: foreground service that starts PhoneEvents to listen for
<action android:name="android.intent.action.SCREEN_ON"/> - optionally
<action android:name="android.intent.action.USER_PRESENT"/> - it must
?

With newer versions of Android, all of these events require your app to be running.
