Okay, I have a similar issue ! MY friend and I are both on Sprint network. She has a rumor touch and mine is HTC Evo 3D. She sent me a video MMS once and an Audio MMS recently both of which are not more than 1 MB and they have a file format .QCP when I look at them. But I cant play/open them. I tried to save the file so that I can tranfer it my computer and probably install a software to play that but still I cannot. The phone says "file saved successfully" but I cant find them in the downloads folder or in the gallery. Can anybody help ? I know QCP is just a generic file format. I tried installing a few players from android market like real player/vlc/quicktime but none of them allow me to play the message on my phone too. Its getting annoying now !
