Bitti09, this was second time?!
When I answer calling, the device was no response few seconds after.
I had to re-power on by pressing power over 20 seconds.
Could you help?
P.S. The cm-12...
Ambient display is not working
Some times after boot up it says no network and if you check you'll see 'unknown IMEI'. normal reboot doesnt solve the issue, you have to reboot to recovery and then need to do a reboot system.
