How are you finding Manjaro for dev work? I set up Ubuntu 18 on a desktop build last year, it's decent but it's still finicky to be my daily driver, so I still use my MBP for work.
I think for a phone I may just drop back to a Nokia 3210 and buy a camera for family pictures. Whatsapp will be a loss, but hey, maybe it'll be nice to not have my phone as a distraction during the day.
There are only 3 distros worth using. Fedora KDE Plasma upgrading after stabl-er point releases, Arch and openSUSE Tumbleweed.
Everything else is very unprofessional or full of technical or human issues. I'm not trying to gatekeep newbies, like, if you use elementaryOS or Linux Mint you're still using Linux. No elitism intended I'm just giving you my opinion.
For exploration or self inflicted harm you can also use NixOS or weird small distros. Although I like Nix' concepts I don't like their implementation or approach to users.
It works well so far. Android Studio works just fine, and Emacs (doom-emacs in Evil mode) is obviously well supported in Linux. My professional development work still happens on a MacBook Pro, as my employer drives that choice.
