Since yesterday I have running Mobian stable on the L5. toooo short for an really good report.
But GPS, BT, Camera are working and calls can be received and made. All packages installed via apt-get and flatpak are working and have actual versions
- Geary
- Authenticator
- Evolution
- Telegram
- Flare
work as expected and Calendar + Contacs get their data from in background running evolution from my Groupware server via Carddav/Caldav.
So far so good 
More to come
