That’s just not true, the latest pixels are officially supported. LineageOS is by far the Android custom ROM with the largest compatibility set.

It means 3/4 of the apps you use aren’t free software which is not an issue with F-Droid.

GrapheneOS only supports modern pixels though. LineageOS is the one with the largest compatibility with both modern and older devices.

I made a website to help finding well-maintained F-Droid apps through Github/Gitlab metrics here: https://dbeley.github.io/fdroid-insights/
