This isn’t the LTE issue some are experiencing. My phone will randomly lose WiFi and go back to LTE, even when WiFi strength is good and I haven’t moved. It’ll sometimes rejoin the network on its own, and sometimes not until I go into settings. This happens at home and elsewhere, so I know it’s not my network. Also, my X never did this. I didn’t pay attention the first while with the phone, so I don’t know if it happened before this week, but now that I’ve noticed, I’m seeing it happen multiple times per hour! I’m going to contact Apple, but I was curious if I was alone here.
