Black Border and Having to "Double-Tap" on apps
I just got a new iPod, and I noticed that you have to tap a little harder than the 4th gen. I figured I would get used to it, but sometimes it doesn't even recognize me tapping the screen. I also noticed for these two apps: Battlefield Bad Company 2 and Call of Duty Black Ops Zombies, that there is a black border around the app and I have to double tap the right of the screen to hold the shoot button down.
iPod touch, iOS 7.1.2, 5th Generation
