mrdarkfusion, May 30, 2019 : MMS messages work fine on my OP7 Pro; I can receive and send with no issues. The problem is when the incoming messages are not displaying who is sending them at all. To workaround the bug, I had to manually click on each message to view the sender details. I have since ditched the stock messaging app, and opted to use Android Messages from the Play Store. Has anyone else experienced this problem?
