I upgraded to the iOS 7 and now I have a moving blue box jumping around my screen that I can't get rid of. How do I make it go away?

Same here! I have been searching for two days and cannot find a fix. Hope they fix it soon as it drains my battery fast.

Settings>General>Accessibility>Switches>Switch Source

Turn it off! 😀

That does not work!!! The only thing that did was to wipe out the operating system and re-install it! Back up your unit first... Unless you have troubleshooted this issue and have seen it for yourself, there is NO point or help in replying!

Also, in my particular situation, switch control was OFF!
