You are having the same problem as I am. My phone now vibrates all the time and there is no missed alert and it aslo shuts down for no reason by itself.My first 2 the screen turned white and had a black spot in the middle. My 3rd one got all fuzzy and then turned the screen just went white. This is my 4th rumor and just last night it stopped charging, I tried changing batteries, chargers everything. So i have come to the conculsion these phones are garbage, get rid of it as soon as possible. Im getting rid of mine tomorrow and getting a blackberry curve.
