I have a GS2 sch-r760 and it is only 2 months old. For some reason the ring tone keeps changing to different songs on my memory card. Any one else ever have this happen? Don't know if it is a virus or what. I have look out and it doesn't say anything is wrong. When I get the emails from them it just says "you successfully changed your ring tone." like I went in and did it my self.
