I saw this before from my brother-in-law. He would send me picks of his dog high importance, when I ask him why he says he isn?t doing it. The next time I see him I asked him if I could see his phone I want to check it out. He has a Sanyo cell phone from sprint and in text messaging there is a setting to mark all text messages as high priority. I think he must have turned it on by accident, I turned it off gave him his phone back and that solved it for me. Don?t know if this will help
