Not too sure if i'm in the right section but my friend has a problem with his Galaxy S and i was wondering if anyone has came across it before and found a fix.
Basically his phone started to vibrate whilst he was on a call and when he hung up his phone crashed. After he switched it off/on, he found that the phone had gone back to its default settings, he lost the internet (although can still use wifi), can't receive calls but can make them and lost the ability to set a screen lock. Also when he powers off, it no longer gives the options of flight mode, silent etc.
He does however still have all his apps and contacts.
I did get him to check the firmware version, its 2.2 which i believe is froyo and not too sure this is helpful but I also got him to check the APN (2 options general.t-mobile.uk (selected) and goto.virginmobile.uk (not selected)). This matched the settings on my HTC so im guessing this is ok.
His phone isnt rooted or anything and he's had it about a year now.
I did find this which is very similiar to what's happening but no definite solutionhttp://samsunggalaxysforum.com/showthread.php/5021-Diagnose-me-apps-crashed-overnight-now-can-t-receive-calls-or-lock-screen
My initial thought was to update the firmware. If he were to update the firmware will he lose everything? (I'll get him to back up anyways)
Any help would be greatly appreciated.
