This is wajeeh here and I am here to help those people who want a change in android ui
I am gonna tell you how to theme your galaxy nexus like window phone
So let's start:
First is the list of app needed for theming
A.i. type keyboard(free)
Photo safari(laggy) (free + paid)
Soft keyz with busy box installed(paid)
Install launcher 8
Move ,change or shrink the tiles
When satisfied download all wp7 apps stated above (available on play store)
When you will press any tile it will ask for the apps, link the downloaded apps with their respective tiles
Install ai keyboard and select windows 8 theme
To make it look more realistic you must enable notification from launcher 8 and disable the notification bar from the desktop and to add more spice try omnirom as it offers cool scroll animation.
If you want you can download icon 7 and you can change the icons on the drawer list by going into settings of launcher 8
You can install soft keys and download the windows 8 soft keys from the net(it requires root)
I don't recommend photo safari as it is very laggy.
If you want more than you call add boot animation of windows 8 [http://forum.xda-developers.com/show...php?t=1936278]
REMEMBER THAT LAUNCHER 8 WILL ADD THAT SWEET ANIMATION OF WINDOWS PHONE.
Support and buy the premiums apps of the respective owners I don't claim any app they belong to their respective owners
