I have had this happen a couple of times now after I have used my iPad in landscape mode for a long period of time (gaming, movies), and was wondering if this is a glitch worthy of taking it in to the apple store or if it's just something that happens? Each time I just reboot the iPad and it returns to normal, but it's still a nuisance. Also, before anyone asks, no I do not have orientation lock on. Anyone else having this issue or have had it in the past? Suggestions? Thanks!
