For some time I have had a random issue with a contact in my list. I hear the text come in from him but when I go to read it and answer it, it's not in my list of incoming text. I keep my incoming list trimmed down so text don't get lost. In order to see what this person wrote, I have to start a new one to him, send it and then I can see what he said along with past texts. It is only this one person this happens with. Any help would be greatly appreciated. My phone is a droid razr on verizon.
