Nice. How does it work compared to Android? Do all apps work (bank, government, shops and so on)?

Not /e/OS user, but it is Android - just degoogled. Uses microG as a replacement for Google services if I’m not mistaken.

As for apps, I recommend checking out an app called Plexus on Fdroid - it’s an app where people report how apps work on alternative ROMs with either microG or fully degoogled. It’s pretty neat.

Surely without Google services it’s AOSP. Android trademarked by Google.

/e/ (also known as /e/ OS and /e/OS, formerly Eelo) is a fork of LineageOS, an Android-based mobile operating system,
