GNU/Linux is not aimed at people who want the most features. It’s made for people who value freedom above everything else.
I would love to see something like Proton but for .apks instead of Windows executables. If it were as easy to install and run android apps on a mobile Linux OS as it is now to install and play Windows games on Linux, we would be in a great place to see a proper Linux phone.
You mean Waydroid? I’ve read that it works pretty well.
