I am on Android 10 and honestly I wish I didn't update. The update bricked by phone until I went in the bootloader to reset it to delete my data. Was it great to have it on day 1 (essential ph-1)? Maybe 5 years ago I would say yes, but now no. It wasted 2 hours of my time. Next time I will buy a phone with a good camera instead.
My experience with Android 9 was similar, but didn't break anything. The UI changes were just not good. I personally know the reason (worked with some of them) - all (unfortunately really all, no idea why this wasn't fixed) designers at Google are Apple users and have a bit if Apple envy. Apple can change the UX for everyone and make users get used to it (even if it is less efficient for everyone, which it is). Why wouldn't Google be able to do it? So Android had the best app switcher, but converged to the iOSish variant. I wish Google would just ignore Apple like Microsoft does it in their Windows.
In a similar way, most journalists are Apple users and there is one "right" way to do things. So we get this nonsense in articles and blogs.
