My phone started acting weirdly. I was trying to scroll through contracts and it was just resetting to the one I had been to. Then I turned it off and on again. Managed to get first number of pin in then tried 2nd number and it was registering as another number. So I turned it off took battery out and now won't register anything. only had it a couple of month. Tried the hard reset thing that didnt work tried without sim card without sd and nothing seems to be working. How do I get it back working again?
