As a fellow Android developer, I feel the same way. Things you mentioned don't interest me either. And now they are (again) pushing large screens, but I'm not convinced Android has any future there (that boat has shipped).

Meanwhile, things that are important to me are not addressed. For example, improving the Play Store relations & process, improving Java (desugaring?) or even just JUnit 5 support....

When I use my phone, I have one basic desire: keep the battery from degrading, so I don't have to buy another device. Yet, Google's 'Adaptive Battery' stuff is not flexible for even the most basic scenarios. And if you're developing, the phone will be plugged in 100% of the time and charged to 100%. I just want to stop charging at 80%, why does this have to be so hard?

So when Google showcases their A/R filter of highly rated chocolates during the keynote, I am not impressed, the phone can't even charge my battery the way I want (and lets not go into Photos app curated "best memories").
