The UI can be annoying, but really that's not an Android problem specifically, but rather a mobile OS problem. Apple's iOS UI isn't any better; it's pretty much the same as a good Android UI. I get the impression that you want a more 'desktop' like UI on a mobile device. Me too. But we are in the vast minority there and therefore won't get it. Hell, even the open source/free projects out there don't care for our tastes (see Ubuntu Touch when it was a thing).
