I purchased the Revvl 6 Pro 5G a few months ago, and everything for the most part has been working great until the last few weeks after taking the recent November 2022 security update. Ever since that update my phone will randomly drop all cellular service (it shows signal, but no data, no speed, just full bars. No 5G, 5GUW, 4GLTE, etc) This also means I lose all data and voice service during this time. I cannot place calls, cannot send or get SMS or MMS messages.
when I reboot my phone, I’ll get service back for 10 minutes or so and then it drops again, After a few reboots it’ll come back for a few days, but then randomly, service is gone again.
I’ve tried a factory reset of my device and setting it back up from my Google account backups, but that still doesn’t seem to help.
I have a brand new SIM card that was installed the same day I purchased the device, so I doubt my SIM is failing.
Is there any menus I can access that have diagnostic features? has anyone else encountered this? I know with recent android you can’t roll back an update anymore once you have a faulty one.
