Look no further than stock Android! I know a lot of people like stock Android for whatever reason, but I have always hated it. To me, it feels immature and cartoonish. And let’s not even talk about all that wasted white space! I am forever hoping Google will take some aesthetic cues from the like of MIUI.

I know it is depends on personal taste, but I absolutely cannot stand the stock Android UI. Unfortunately, there are no other options if you care about security, quick updates and devices supported for long. Also, since other UIs (MIUI, EMUI etc) are not supported by Google, the apps seem very different from the OS — i.e. there is no continuity.
