I'm having two frustrations with my iPod Touch. 1) When playing music the screen goes to sleep after a few moments of disuse. That's fine. When I hit the power button or the home button to wake it up, it will do one of three things. It will either a) show the album artwork and the name of the current track, b) show the artwork, track name, and controls for play/pause and volume, or c) show nothing about the music at all and have the default background and unlock screen. Why on Earth is this behavior so inconsistent, and how can I force the iPod to always display the play/pause and volume controls? 2) Also, when waking up the iPod after the display goes to sleep sometimes it takes 5-8 seconds for the iPod to respond after moving the slider from left to right. It just hangs there with the slider to the right for several seconds before unlocking the interface. This usually only happens when playing music, and has only started hapenning since updating the iPod to iOS 5. Does this happen to other people? Is it a known issue or is there something the matter with my iPod?
