Sprint Samsung Epic 4G (besides having issues receiving emails which has been an ongoing issue) has now stopped opening pictures that are texted to me. I receive the following error: mms transaction is failed. I do not see an error number - just these words flash across the top of the phone when I try to download the photo. When I try again, I eventually get a message that download failed. I looked at similar topics on forums - tried going into Settings/Applications to clear data or cache but these items were greyed out. Any ideas would be appreciated.
