Looks like a new version of Android has come rather quickly, though it wont be a evolution but just a fix. Android 4.4.1, still KitKat is now live for Nexus 5, Nexus 4 and Nexus 7 LTE. The camera enhancement is the major aspect that Nexus 5’s update seems to be focused on as it has shown a considerably better performance. The camera app launch times are improved by a second and shorter shutter timings gives faster capture speeds. Increasing the camera’s frame rate also allows auto-focus to work faster, eliminating some of the issues from the current firmware. Also in the HDR+ mode there is now a progress indicator to give users a better idea of the overall process. The photos taken with the new camera software are less washed out than before, with more vibrant colors and more contrast, as well as more accurate white balance. You might check out the images below to see the difference in the picture quality after the update (courtesy of GSMArena).

Now for the Nexus 4 and Nexus 7 the update isn’t a game changer but it surely does offer numerous fixes that the users complained to have since they updated their devices to Android 4.4 KitKat. If you wish to make the update land to you more quickly than ever the you can follow the download links below.
