Hi, I noticed for past few weeks, my tablet is not playing any video files. I downloaded some you tube trailers via tubemate which were working fine previously. Now if I play then, I get a blank screen. No error , no video / audio. Just a blank screen with video player. Some times it shows loading circle, but it never completes. VLC player was working fine on it. I watched couple of movies it. Now VLC will also not play anything. Same issue, blank screen. I tried ES Video player also, same issue. Anyone knows what is the issue and how to fix it ? IdeaTab A2107A-F. Details are -Build No. - A2107A-F_S486_130221 Android - 4.0.3 I haven't tried factory reset yet. If thats the only solution, I may try it over the weekend. But I wanted to avoid it TIA, Jab.
