I have been having this issue ever since I upgraded to jelly bean. If i go to a site like allsp.ch or 1channel.ch, I can play videos in the original mode on the webpage with ads all around without my phone locking, but if i make the video full screen, my phone will lock after 30 seconds of inactivity which is what i have it setup to lock at. This is the opposite of what it did in ICS, which is lock after 30 seconds of inactivity with a small video, but stay on during full screen playback, which is what i want it to do. I can play youtube videos or videos on my media server in fullscreen with no problems, it only seems to be with videos on the internet, like it doesnt recognize that its in fullscreen. Is anyone else experiencing this issue or have any ideas on how to fix it? Thanks!
