You know, with this phone, if its not one thing, its another. None of my videos will play since the latest update..I get sound but just a static picture.
My TB did the same thing so I restarted it and they work now, except youtube it still freezes up but just after restarting it worked ok. This doesn't bother me because I don't watch youtube much.
I got GB when it was first available a month ago then the patch last week. All vid formats have worked throughout: mp4, wmv, youtube, etc. Stock everything.
