Thank you a lot! Have you tried LineageOS? I assume that this could fix your issue with connectivity.

Thanks for the info! Wondering how it will work with my carrier. How is the battery life? Do you use stock or LineageOS?

PP about two years, PPP about six months. Yes, there is a small crack with the keyboard case with PPP.

I use ArchLinux with Plasma Mobile. Battery life is bad, but I bought the Pine keyboard which makes the battery life normal.

Not anymore, I have both and call and alarms from sleep works :)
