Pad lock icon everytime. How to unlock?
Hi!
Now i've turned on (wake up) my iPad 3. Slided to unlock. Lock screen has disappeared... BUT.. there is padlock icon at the center of status bar (where must be time). It is NOT rotation lock icon! It is like on the lock screen.
And iPad does not offer me "turn off" after 5 seconds holding sleep/turn off button. And i can't see settings. When I tap settings - application is starting, i see usual background of settings app, but there aren't any settings or even text... Also Wi-Fi is not connected (despite i'm sure there is wi-fi network and my iPad knows this network). All other applications work as usual...
And iPad locks and unlocks by pressing appropriate button.
So, does anybody knows this situation and what does it mean? Is it normal behavior of iPad or is it some glitch?
P.S. Problem was solved only by hard turning off (hold Sleep and Home buttons together for 10 seconds).
iPad (3rd gen) Wi-Fi + Cellular, iOS 5.1.1
