It's my only phone. I gets hard when somebody tries to force an Android app on me. Waydroid works but takes a lot of disk space and is not very convenient (Purism promised usability updates though); the battery life is only enough for a day with light usage (but you can replace the battery without tools); js-heavy websites are slow (but NoScript fixes that). Calls, texts, taking pictures and video recording work. I never tried MMS, but some people made it work, too.
I'm very happy with the desktop Firefox (with Ublock Origin!), full terminal, all Debian packages and the full desktop mode. Also with lifetime updates and independence from the megacorps.
