Hey guys, I just wanted to put this out there. I was encountering many bugs in iOS 7. I was at the point where I was about to downgrade back to iOS 6 when one of my friends told me to do a fresh restore in iTunes. This cleared literally all of the problems I was having! All you have to do is open iTunes, create a backup, restore your iDevice, and then restore from the backup. Apparently updating OTA can cause some problems, so a full restore in iTunes is the fix. Hope this helps someone!
