Mine is still typing whatever it wants. Happened after I switched otter boxes. The first one I had on it since the day it was bought, it had the semi-thick piece of plastic connected to the case to protect the screen. This new case does not. That could be my problem. It also does some weird stuff if it's to windy. It is impossible for me to type in front of a fan. It'll go all satanic on me and type whatever letters it wants lol, so idk if it's the heat that causes these issues. I doubt it. I just turn mine off and back on. I'm talking to an apple tech tonight. I can't afford a new phone. This just sucks because I really like Apple products, but I might go windows next time :/ :(
