Hello, I'm new to android having recently left my iphone for the S3, and I'm hoping to get some help from the hive mind. I have an AT&T S3 (U.S) When someone sends me a picture it comes through as anonymous sender and in the message itself "message not found". This happens whether its from an iphone user or an android user.. I have already unregistered my old iphone, tried sms apps (they freeze or crash) and compared my settings to my husbands s3 (He rarely has this happen) none have fixed the issue. (I would post a screenshot, but its not allowing it since I'm new.) Any ideas/suggestions before I give up and just reset the phone, start from scratch and pray it works? Thanks!
