my htc one x(from at&t) about 2/3 days ago first started acting up. Someone tried calling but my screen was black only the little icons at the bottom were lite. the next day my screen wouldnt turn on for a few minutes several times through out the day. so id reset my phone and that night turned my phone off. that next day was fine no problems. now today everything was fine and good and then my screen times out and i go to turn it back on and it wont. its been 2/3 hours the touch screen works and from what i know i turned off my phone then turned it back one but nothing happened. Right now i have it off and charging. Please if you can help it would be greatly appreciated !
