Clearly none of those, I suppose, since it seems that your question was loaded in a way that the answer to each is "no". I do not delve into the curtain behind the UI.
No one was stopping you from adding to the list with your own observations. I did mention the UI though.
I do not delve into the curtain behind the UI. Nor I care to. What I find ridiculous and dumb is that people don't see the obvious similarities in the two OS, with regards to the UI look and feel.
The UI look and feel ? Of Android and iOS. Did you read my previous post about that. Let me quote you the appropriate paragraphs :
BTW, this is Android 1.0 :
This is Ice Cream Sandwich, Android 4.0 :
Both are pretty much the same. Widgets, application launchers that can be positionned anywhere on screen according to user input. The UI didn't change much, except for its theming and styling. The core of it has remained the same. The core of it is also quite different from iOS' UI. Here for reference :
Rigid icon grid, no way to move things around as the icons place themselves linearly, completing existing rows and pages before creating new ones. This is minimalist, it is recognizable from one device to the other.
The design goals with both these UIs are quite different. Andy and Google went with user customization in mind, making the device the users device'. Apple went with a different approach, a strict UI that is unbending to a user' will so that any user that picks up any iOS device will instantly recognize how to use it efficiently.
Both approaches have merit, both target different audiences. To claim one is a copy of the other or vice versa is inane. It's ignorant of every aspect of the design of both and it ignores the fundamental differences between the systems.
After reading this, can you still sit there and claim the UIs are "copied" from each other ? The underlying design paradigms of both UIs, the goals that their respective designers wanted to attain, all seems pretty different with me. And it's obvious to anyone using either devices. They are both different in their feel and use.
From the beginning, Android was positioned to be an iPhone-killer/alternative, especially in the WAY the OS behaves and how you navigate it (multi-touch pinch, swipe, zoom, app-driven platform, general OS design, etc.), but in a much more customizable way.
Wait, app-driven platform ? You mean like Symbian before it ? Windows Mobile 6.5 ? J2ME runtimes on dumbphones ?
Newsflash, that's what the smartphone market was before the iPhone and after the iPhone. App driven devices. In fact, Apple missed the boat on that in 2007, by announcing loudly and proudly that developers were to make "Webapps" for iPhone. Only after people clamored for a native SDK to match what was out there for other platforms did they release one.
I remember writing software using Sony Ericsson's SDK with a phone emulator and all, back in 2003 for my T610.
As for navigation, I have never seen Android positionned with any kind of such rigid navigation paradigms. Quite the contrary, in 2008, the first Android phone shipped without multi-touch enabled and with a hardware keyboard. Touch was not being touted as a killer feature at all. In fact, even the Nexus One didn't enable multi-touch until 2010 in the US, when it was ascerted that Apple didn't hold the patents they said they did (no one can't patent the whole of multi-touch, the concept has waaaaay too much prior art at this point) :

So on this I think you're just confused and seeing what you want to see.
I've seen what Android was before, and after the iPhone were introduced, and they're wildly different. It is a common perception that Android offers an experience similar to iOS, albeit not identical. Granted, as releases and updates come out, I see that gap grow further apart.
Go back and read my entire post. (click the arrow next to my name on the previous quote of my own post). Android has not changed from before and after the iPhone. Android is still the same it was. A hardware agnostic platform that can run on many form factors. You're repeating stuff I've provided evidence against. I can't argue if you ignore what I posted earlier, that's just impossible. Provide counter arguments if you want, don't just repeat things as mantras after you've been shown they are not the case.
Win Phone 7/8 would be an example of something actually different, in look and feel.
Because it uses tiles instead of icons ?

Tiles to me look pretty much like icons. You know what they say about Roses by any other name...
The plain fact is Windows Phone is different, Android is different, iOS is different. None of the OSes look alike or have conflicting design goals.
So, ridiculous and dumb it is. You keep your perception, and I'll keep mine. Cool?
Sure, if you want to have no basis for your perception, I guess it's cool. I'm just trying to understand on what basis you're forming your perception from. It seems even you can't properly explain it, which to me means you maybe should reevaluate it ?
I have provided plenty of meat on which I base mine.
