iPhone 4 regularly crashing
Hi,
2 year old Iphone 4 crashed around 6 weeks ago and since then has been crashing on a regular basis. When it does this it will not switch straigh back on and can be hours before it will. Was doing this on iOS5 and after installing iOS 6 so don't think this is a software issue. I have done several restores, both from backups and as new phone, but still doing it. No installed apps at the moment and STILL doing it. Went to Genius bar but all they did was yet another restore as new, that was over a week ago and has since crashed 5 times. I at my wits end with this as I can't use the phone for any apps and now even using WiFi and Safari is crashing it - only seems to work ok for calls and SMS. Have checked diagnostics and there are currently 4 x awdd logs, 2 x log-aggregated logs and 3 reset counters, all with date stamps.
Can anyone shed any light on this? Is this a processor fault, battery fault etc etc?
Can send copies of los if needed.
Thanks
iPhone 4, iOS 6
