Recently the latest build of Android 4.4 KitKat screenshots were leaked on the web, and a new video has popped up which shows off the Nexus 5 and Android 4.4 in detail, quite a bit of detail actually as the video is Full HD and 7 minutes long. The build of KitKat inside the video is older than the one leaked by TuttoAndroid. And the Nexus 5 inside the video is a early prototype, considering there's no Nexus branding on the back.
The video shows the Nexus 5 in every possible angle, and details Android 4.4. Comparing this build of KitKat with TuttoAndroid leaked images, it is clear that this build is a bit old, as it's missing some key elements, like transparent notification bar in the launcher, camera shortcut on the lockscreen corner, revamped dialler, changed app drawer & icons and Tap & Pay feature, and more.
The thing missing on the phone is the big Nexus logo, which we've seen repeatedly in previous leaks on the rear of the phone. The rest of the hardware is the same, which include, volume rocker on the left side, the headphone jack and microphone on top, power button and SIM tray on the right, and two stereo speakers with micro-USB plug on the bottom. There also seems to be a circular speaker on the top front center of the device.
In related to the news, according to Android Police, the stock launcher in Android 4.4 is being bumped to version 3.0 and may come with a new name - Google Experience. The report revealed that the launcher now has com.android.launcher3 as it's new package name, earlier it was com.android.launcher2, which is a significant change, as Android has been working with Launcher 2 since 2009.
Additionally, there are some items which refer to the launcher as com.google.android.gel, where the thinking is that GEL stands for Google Experience Launcher. The same can be found in this video at 1:05. There's something called GEL Stub, which undoubtedly refers to Google Experience Launcher Stub.
