Linux phones are entirely impractical for most people. I live in India, and there are several apps I need to use to access government services that only work on iOS and Android. Some services aren't even available over the Web.

We're at a point where any successful mobile OS will at least need to support running Android apps, preferably directly from the Play Store. I suspect this is one of the reasons Microsoft is adding Android support to Windows 11.

I like the idea of an entirely FOSS phone, but sadly that ship sailed years ago.
