Android. Google doesnt invest anything in AOSP it seems, GrapheneOS is the only really well made Distro.
Androids security model is a joke as every phone is bloated with malware that has full access over everything.
Banking apps need Google, map apps need Google.
There is no split screen in AOSP since forever.
No tools on the lockscreen. I am not talking about crazy ios like tools that are basically a seperate OS, its still a lockscreen. But camera and torch?
So many restrictions. RootlessJamesDSP is a good example of crazy workarounds that still dont work in the end. No FOSS appstore with autoupdates is also a pain.
