Whenever I try to watch a video in a web browser on my Nexus 7, I always have problems. Sometimes the video doesn't play, sometimes it's very choppy, sometimes the playback controls (which are awful by the way) are placed randomly on the screen, and sometimes videos won't go full screen. I thought that maybe Chrome was the problem, but Dolphin Browser is just as bad, only with slightly better controls. Is there a anything I can do to improve this? iOS users I know don't have problems with this, so why does Android?
