Some of the changes with the Android 4.4 KitKat (according to the tipster) includes flat icons, semitransparent navigation and status bar, redesigned phone app, and many more. The photo above shows the homescreen with some icons that are really flat.
It is also said that the notification bar color and the small icons on it (battery, signal and wireless) are dynamically changing colors depending on the application in focus. Blending!
Yes, these photos are intriguing. We are not sure of their authenticity but we are not saying that they’re fake. Let’s just wait for more details coming out soon. [Source]
