Ok this is going to sound a little confusing. My ipad i use mnainly for reading epub books in the evening before bed. I have the auto lock turned on so that the screen will simply sleep after 2 min NOw when ive finished a chapter and want to sellp i leave the ipad alone, no interaction and let it sleep. Recently i havenoticed that the screen will dim and then brighten as if i had touched it. It will then dim again and then fall asleep. In this order: Dim - Brighten without interaction - Dim - Sleep Im confused that this happens when i let it sleep while leaving the ibooks app open so i can simply resume where i left off. Is there something wrong with my ipad or am i worrying too much. I this a bug from the ibook app? Any thoughts and insight would really help me. Its still new maybe only a month at the most old. It was brought to me from the UK as a birthday present. I think it was on standby for the time it spent in transit from Manchester to Bangkok. I little profesional opinion would be greatly appreciated.
