Has your device been exposed to moisture (been dropped in water, or such).

no it hasn't..just started doin that

Have you popped the battery out for 30 seconds and then put it back in the device to see if that helps at all?

i did that a number of times hey,the problem is still there

Sounds like a hardware issue. I'd recommend contacting your carrier to see if it's still covered under warranty.
