I just purchased the Samsung Galaxy SII a week ago and have noticed that while watching videos from Youtube or other sites and/or apps, the videos will begin on a blacked-out screen. It happens on a large majority of the videos I click on. The video screen will be completely blacked out but I can still hear the audio just fine. The problem seems to also freeze up the controls a bit, as well. What makes the whole thing worse is that since the video controls are located on the video screen, I cannot turn the video off, pause it or even mute it...so I'm stuck listening to a video I cannot see. Anybody experiencing the same problem? Know how to fix it?
