It's a hardware issue. Just went thru this with my wifes phone. It would open apps, send texts, do random stuff, etc. This was a phone that was never dropped, never got wet, and was kept in a purse. Apple store wanted 120 bucks to fix it, luckily I had a square trade warranty on it. We tried everything, several wipes of the phone, disabling features, etc..
