I rooted my Samsung-sm-g930a (Galaxy s7 AT&T)
And after I did, the VOLTE showed up... I thought nothing of it because it is Voice Over LTE but a week after I did that when i tried to open an app it closed the app 2 seconds later (almost immediately) and if I restart my phone it gets stuck at the AT&T logo I can boot it into recovery and reset the device, this fixes it temporarily then 3 days later it does it Agian. Any idea how to fix this?
