My google app has suddenly become a gorilla wearing an army helmet. It is not very pleasant to look at. What happened? Where did this creature come from. How did it get its face on my google app. I did not put it there. I am serious. This is scary.
First reaction was to laugh and ask, "which army is that and what rank?" But that's not nice. To be more serious:
If an app is causing problems, regenerate it by pressing the Home button twice to show all recently used apps on the bottom line. Press on the offending app until it starts to wiggle (they all will) then press the red minus sign to close the crook app (you won't lose it) then restart your iPad and slide the restart button back to On.
If still no good, reset your iPad by holding down your on/off button and Home button at the same time until the Apple logo appears. Let go the buttons and the iPad will reboot. (Could take a minute or so)
If OK let's know how you got on, which could help others.
