often times when i click on one text message, it brings me to another one. im trying to text sarah back, and when i touch her text message, a series of text that i had with dan will come up from a few days earlier. also the phone calls people randomly. at least once a week ill be driving with phone on my lab and all of a sudden i hear someone on my phone shoulting my name. ive got up to dave avg antivirus on my phone. my girlfriends phone does the same thing and she doenst have an antivirus. does this happen to anyone else?
