Hi, my friend is running Stock 4.3 MK2 with no root and has a weird issue with the stock messaging app. Whenever she receives a MMS group message and she replies back, a message is sent, then that same message is received back to her on the thread. (See Photo) I uninstalled all other SMS apps, but the problem still persists. Anyone have any troubleshooting tips? Would a Modem flash resolve this issue?
