If you have were as unlucky as me and found: Settings>General>Accessibility>Switch Control, I can help you turn it off. It took me about an hour to figure it out. "Switch Control allows you to use your i[Product] by sequentially highlighting items on the screen that can be activated through an adaptive accessory." There are options for switches, and other tweaks. I don't know what accessory a person would use with this, but it was an hour of hell haha. I tried to take screen shots, but the magic blue/purple rectangle is invisible to screen shots. Any ideas what this is for?
