In my reviews, I frequently abuse and pick apart TouchWiz, Sense, and MotoBlur. I point out flaws, say "that's stupid," and wonder what the heck was going on when someone approved whatever half-baked change they've come up with. A lot of the UIs shipping on phones today are bad.
But it's not just the 3rd-party skins. Stock Android isn't perfect either, and that's what we're here to talk about today. Jelly Bean has all sorts of confusing user interfaces, weird bugs, things that don't make any sense, and things that desperately need polishing.
I criticize because I care - that goes for Sense, TouchWiz, and MotoBlur too.
