I have been facing troubles with my Lumia 920. Since 2 days ago it's randomly getting stuck on resuming while trying to unlock the screen.
When this happens, I cannot do anything on the phone. None of the buttons works, and the phone only responds when I do a soft reset, yet the
problem keeps appearing like twice per day and I have have to soft reset again. To me it seems like kind of a virus, but do not really know.
Have any of you guys seen this problem before ? Any idea of could be causing it and how I can solve it?
I was thinking in restore the phone, but there comes up another question. The reason for which I have not done this restore process yet is because
my Lumia 920 is an AT&T SIM unlocked phone (unlocked by code I guess), and of course, I am not an AT&T customer nor live in USA :straight:, so I do not have
any idea if after restoring the device it will get SIM locked again. Anybody in here knows if this could happen ?
This the firmware revision number I have: 1232.5962.1314.0001
Help please!!
