I'm using C6603 on 434 rom and found an issue is the phone would auto restart in standby peroid. When I wake up the phone, there is 'mobile data is disabled' on the notification area that means the OS has been restart ( correct me if I'm wrong), then I check the 'Up-time' in status, it is not the real standby time, any one also has this problem? Any clues? Thanks

do you have stamina mode on? if you do that's the reason why the data its off

Thanks for reply. The stamina mode was off, no huge softwares installed just like whatsapp, no system level software, no firewall, no anti-virus, no security software..but still got randomly auto-restart, I mean sometimes when I wake up my phone I found the 'up-time' is re-counting. This is my second xperia Z so I never consider it as a hardware issue. Any more suggestions? Much appreciate.

you could try to repair your phone with SUS or PCC and see if that does it

I did it in both US and flashtool to re-flash the ROM, the issue still occurred.

that's quite odd, how about if you repair your phone or re-flash your phone > do not install any app, uninstall mcafee > do NOT restore any settings (using the backup & restore app) and check if the problem persist, if it doesnt then its an app acting up, if it does, you have to take it to a Sony repair center.

Yes now testing on a pure system with wifi connectivity, no settings restored, mcafee uninstalled. Added a google account for contacts sync. Thanks for your swift reply.:smileylaugh:
