Galaxy S7 sometimes doesn't get any reception after disconnecting from Wifi
Sometimes if I disconnect from Wifi, I don't have any data or proper reception. It'll show I have full bars but of like Emergency only. I can't receive texts or make phone calls, until sometimes several minutes later, I may get 3g but it'll never get back to LTE unless I restart the phone.
I've tried going into developer mode and leaving the Data connection live even on wifi but it doesn't fix the issue.
