My grandmother got her iPad somehow in this state where it seems to be in language setup, but taps dont work as expected, rather they activate unusual boxes on the screen:
How can I fix this? Holding down the power and home button for 10 seconds restarted the iPad but the same screen was there. No interaction seems to be doing anything to advance the setup, the boxes that pop up seem to be interfering. The box in the image appears after tapping.
