You have VoiceOver turned on.

If VoiceOver is on and you want to turn it off from the device instead of from iTunes, remember that a double-tap acts like a single tap and you need to use three fingers to scroll when VoiceOver is on:

Press Home.

Tap Settings. Then double-tap Settings.

Tap General. Then double-tap General.

Use three fingers on the screen to scroll to Accessibility.

Tap Accessibility. Then double-tap Accessibility.

Tap VoiceOver. Then double-tap VoiceOver.

Tap "On" next to VoiceOver. Then double-tap "On" to turn it off.
