The iPt 5th gen. ULAK case I got for the 6th gen. touch fits perfectly, but its window fits too exactly the dimensions for the display, which makes it very difficult to drag icons from screen to screen, and to display the Control Center by swiping up from the bottom of the screen. The case's beveled frame prevents your finger from going to the edge of the screen the way the iPod expects. You can drag icons and display the Control Center, but it takes patience. After googling the problem, I learned that it had occurred with the 5th gen. touches too. Unless Apple adds some leeway to make swipe detection more forgiving, there are a lot of cases that will be more of a hindrance than help. I found a workaround that's clumsy but works well enough that I'm keeping the ULAK case: under Settings, click General > Accessibility > Accessibility Shortcut and select AssistiveTouch. Now you can display the Control Center by pressing the Home button three times and clicking on the Assistive Touch button that appears.
