I just switched from an iPhone 4 to a MotoX with Android. When people try and send me MMS messages with both text and a picture in the same message, the picture shows up as a white square with a play button on it, like a video. When I click play, the screen just changes to all white with the text at the top, but the picture will not show up. When the same message is sent as just a picture, with no text, it works fine.
