I have Roomie set to auto-dim, but not shut off. If a dialog window is open, or a pop up (like volume slider) is open when the screen dims, it won’t come back up to full brightness when touched. It just ‘sticks’ on the dim setting.
Additionally, when dimmed, if the first touch is on a popup dialog like the Volume slider, the screen won’t re-brighten either.
I have to cycle the iPad off, then back on to get it back up to normal brightness.
I swear I’ve seen this bug in other apps in iOS5 and iOS6, so not sure if this is an Apple problem or a Roomie problem.
This is on an iPad 3 with iOS6.
