Today while dialing a number I got notification that HTC Phone has stopped working. Then I dialed again and same error came up. Then the phone rebooted and got stuck between HTC white screen and T- Mobile screen. Both screens are displayed alternatively in a loop and nothing else happens. I am not much experienced with android and just bought this used phone so please advise what should i do. I don't have a backup of my data but i understand that it will probably be lost but I'm hoping this OS issue can be resolved. A bit of history: I was having internal storage issues so I used the android-sdk to select the default location of apps to sd card but still the storage issue was there even though apps were being installed on sd card. Before this problem, I updated a few apps like Google maps and the storage was low so maybe this issue is related to internal memory. But 1the last I checked Google maps had successfully updated. One or two apps might have been updating during this happened. Please advise how to solve this. Thanks!
