I updated Z1 with 4.3,after the update for some reason Z1 restarts while unlocking to the main menu it happens after every 3 or 4 hour its annoying and fustrating,i've tried few methods suggested on another forum by a moderator.Now the problem still exsists.
I have tried Sony repaire service,i have tried hard,factory,hold press down volume as well now i'm not sure if i should go ahead and keep repairing it unless the phone dies it self.
Is there any geniun solution to this problem?help?
