I have an S6 phone that no longer has service but I still use it to play games. It powered off because I haven't charged it in a while. Now when it powers on, I need to do the pattern lock, but I've forgotten what it was. It also needs it to turn off and to get to the settings. Does anyone have any tips or resolutions?
If you connected to wifi or temporary put your sim card into the phone you might be able to use find my phone to unlock your device remotely. I believe Samsung and Google offer this service so if you have one of these accounts on that phone this might help.
