My s5 received a sms message from my cousin, in a brand new thread, and It would not download the message. I was connected to both mobile data and wifi. after receiving that message I received other messages from other family members, with no issues, who had received the original picture message. after a few minutes, the message popped up with a note that it had expired and was no longer available, and the thread deleted and I was not able to view the picture. I sent a text to my sister who then forwarded the picture to me and I received it with no issues. WHY!!!!!
