UI- there should be three screens. First one for home screen. Second for tile screen and the last for applications list. For the home screen there should only be a plain wallpaper with some basic tiles like call, message etc and the icons should be customized to the bottom so that the wallpaper will be visible. Now by swiping left, here we get the tile screen. The home screen wallpaper will be dimmed and the tiles will be arranged completely as our wish and looks like floating on the home screen wallpaper.Again by swiping left we get application list. If we want to go for tile screen when we are in the application list screen, we can get out by simply reading the windows symbol button one time, If we want the home screen then double time.if we are in the tile screen, we can go to home screen by swiping right or by single taping the windows symbol button.if we are in the home screen and we want to go directly to the application list then by simply clicking the arrow mark in the bottom right side corner. How is it guys. Hope you may like it please comment on it
