I dropped my evo 3d, not too bad, it has an otterbox so I didn't think anything of it, but shortly after it restarted on it's own, it would work for a little bit and then restart again and then it just degraded from there. Tried taking the battery and memory card out and then restarting, nothing. Took it to the store where I bought it and they reset it all the way back to it's original state, still no good. The clerk thought maybe it jammed up the accelerometer....... Any ideas?
