Some, not all MMS messages will not stay open.

Hi, A few of the MMS messages I try to open, open for a second and then close automatically. 99% open and allow me to respond but a few simply close immediately upon opening.

Hi Michael and welcome to WPCentral. What device do you have? What carrier do you have? What type of MMS are they: pictures, videos? How big are the pictures or videos? Do your friends have the same carriers as you? Do you know what kinds of phones your friends are using?
