Oh there's a ton more missing than that if we're talking the gritty take on 15 years. There's Android 4.4's FUSE migration which setup a generation of Android devices to just randomly turn to crap over time, the iOS-ification of the OS by blocking things like log access behind non-standard permissions, there was Doze marking the official start to "important things can live in closed source Google Play Services", there's the death of the AOSP apps so now there's not even a maintained calculator app for Android proper, there's SAF bungled launch with 11 that made I/O for apps 10x slower (not sure they ever even fixed that) I owe a lot to Android in some ways, my early career was putting together embedded Android deployments, and eventually I even lead a team that launched an Android based consumer product, but my phone is an iPhone, and that's not changing any time soon for a reason.
