Google has officially announced the next Android version, Android 4.4 KitKat, but the release date and features of Android 4.4 KitKat are not yet revealed by Google. If German KitKat Facebook page comment and Google's Easter egg are believed to be true, then Android 4.4 KitKat is confirmed to arrive in October, most probably on 7th Oct or on 14th Oct, as per the rumours.
Coming to Google's Easter egg, the video of that alleged Nexus 5 found in a bar running on Android 4.4 KitKat speculated that Google is eliminating the blue Holo theme from the OS, and is planning to replace it with a white/grey colour scheme. And, now a picture from the updated Google Korean keyboard IME app reveals more information about Android 4.4 changes.
The official image is now taken down, but thanks to Android Police for the mirror. As you can see in the image (below), the app was running on a tablet with Android 4.4 installed, because the status bar has light grey icons and clock font, rather than ligh blue icons and font, as seen on current Android version. The same colour icons and font was found on leaked Nexus 5 video.
In addition, the debug icon in Jelly Bean is a little Android Jelly Bean, and the debug icon on this screenshot is a piece of Android Key Lime Pie, so this screenshot was probably taken on a device that still had the decoy Key Lime Pie ID. We knew Google was keeping things under wraps with regard to the KitKat naming, and it looks like designers are still working on getting the Android 4.4 graphics updated.
Also, if anyone believes that manufacturers drop clues about launch dates in the time that clocks are set to on an unreleased device, then you might see the 10:07 time set on the picture of the Android 4.4 debug icon to be a clue pointing to an October 7th release.
