@epifn I have but not on the PinePhone, only on a Nexus 5 and OnePlus One. Atm, Ubuntu Touch is more useful for end-users, but I personally don't really like it.

It's too far off a regular Linux distro, for example it has a read-only file system and you can't update with `apt-get`. Also, way too many apps are in fact Electron apps which I absolutely hate.

I prefer SailfishOS really, but that has the problem of being a proprietary hell.
