When coming off wifi, my S21 cell network is grayed out and I cannot get online or make any calls or texts without turning airplane mode on then immediately off. This happens very seldom but unless you're looking you wouldn't know it unless you're using the phone. I'm on the Verizon network. Is this a common issue? It seemed to start after updating to One UI 6. Is it just happening on the S21?
My old LG model had an auto feature I think if I remember correctly that said something about using Data connection when there is no wifi under the Settings/Network Comnectuons some place that I had to disable I believe becuz of something very similar but mine would constantly turn the network off period or like urs I guess but mine was constantly trying to switch between these causing no connection I mean but disabling it resolved it so just a suggestion
