I've been trying to squash an annoying situation where the full screen mobile template messes up on Firefox on Android. I found another game that's set up basically as mine: http://gamepyong.com/ints/ints.php It has the same problem. I'm having this issue in both 2.04 and 2.05. SO - what's the issue? Well, the javascript seems to think the game, or the webpage is/should be larger than the game's height. So it pushes the game down 10/20 pixels, and then if you touch that area you can scroll down. Since you then can scroll down, the page is never stationary; you can touch and drag the page which ruins many games basically. I'm seeing this problem on a Samsung Galaxy Tab, SM-T310 Android 4.2.2 Any idea on where to start to troubleshoot this? Pic of the problem, notice the black bar under the nav bar, it should not be there:
