If I set my brightness on the iPad all the way down with auto adjust turned off and subsequently go into the iBooks app the brightness goes back to full. This persists even after I close iBooks and go to the settings. The brightness "slider" still shows the lowest setting possible but the brightness is at max. A slight wiggle of the slider corrects the issue, but of course if I open iBooks again the problem re-occurs. Is anyone else experiencing this issue or is it simply a bug in the new iBooks update they just released? Thanks.
