With Google locking down Android are there any viable mobile OSs, not based on Android, usable as a daily driver besides #SailfishOS?
I haven't used any of the other mobile Linux OSs besides #Sxmo for a short while.
And "viable" is of course very subjective but minimally one should be able to make and receive calls without any issues, SMS, mobile data up to 5G amd VoLTE, run a Signal client and browser.
