1- A new animation to show users how to unlock and answer a call
2- Multi-colour LED notifications from the Start button light
3- Interactive Live Tiles (e.g. for music). Tapping on the centre will open the app, while tapping on the sides will expose the controls. Reserving this for especially large tiles would be an elegant solution to the issue of the screen getting cluttered by too small widgets.

easy to switch between 1 or 3 row
easy to arrange actions
easy to add/remove action
new actions
on tap to on of off
double tap to opened it
tap and hold to delete or move
5- An improved store with a 2 or 3 columns option and apps arranged in a “my apps” list.
6- An improved Messaging notification which uses a draw-down toast.
7- vertical controller option in bottom to improve one-handed use.
8- real split-screen multitasking with new features with drag and drop.
9- A new Lumia Share app to make WIFI Direct and other local sharing service easier.
