On Android 7.1.1, latest Avast anti-theft 4.2.0.8278 . Mobile data is off (out of range).
If I send a text message from another mobile to my mobile to locate it, I get a text message back saying that this was successful and that my location has been reported to my predefined trusted number. However, if my mobile was locked, with the screen off, I do not get the position text message back as well.
If I go to the mobile I am trying to locate and simply turn on the screen with a single button press, without unlocking it, the location text message gets sent and received by the first friend (predefined) mobile.
It is as if the mobile I am trying to locate wants to tell me that the first message has been received and is waiting for an acknowledgement. This is clearly not what I need to happen. I need the phone to be located whatever state it is in (provided it is on).
Last time I tested this I didn't have any problem, but I'm not sure if the screen was off and locked at the time.
Help!
