I have a SamsungSGH - T159 that I got in June and it's started to turn off randomly even though it's full battery. It turns off when it's closed in my pocket, sitting on a table, during calls, really anytime so I know it's not because I'm jostling it. Also I never got any liquids spilled or dropped it.
My service provider is WIND and to get it checked out and fixed at the warranty store you have to give an $80 deposit and then get a replacement phone for $10 non refundable, or else have nothing for the 2-4 weeks it takes to have it fixed.
This sounds like a pain so I'm seeing if there's an easier solution first! Thanks.
