I have a HTC Desire X, I was watching YouTube perfectly fine, went on NBA Gametime which worked and then crashed, after this i went back to youtube to find out it wasn't playing videos. I went to open a video I recorded on the phone which wouldn't even play! No videos play on any app or website... 'Cannot play video, Sorry, This video cannot be played' It comes up with a second of audio and the first frame of the video but then has the error message. I uninstalled NBA GameTime which has done nothing, rebooted, still nothing. No modifications,only bought a month ago. I'm new to androids so very confused and annoyed. Please help.
