I took a video with my phone and it displays the error when I try to play it back: "File cannot be displayed or played." Is there anyway to get the video to work? It seems like a get the error when ever I take a video over 20ish seconds, when I do the below steps, I can take video but it isn't long before I'll take a video and get the error again. It's really annoying. pull the battery and put it back in. hold the home button, and power up the phone. when the little android guy pops up on the screen, hit the search button. go down to "clear cache" using the volume button, and select it with the camera button, then go down and select yes.
