The update roll-out begins after Dave Burke, Google's director of engineering for Android, revealed that the Android Team is working on the latest iteration of Android KitKat version 4.4.1. The new update, which is designed to fix the bug issues of the Nexus 5 camera, would roll out over the next few days.

Following this, Google confirmed Android 4.4.1 KitKat update for the Nexus 5.

"All of this gets a boost with an update to Android 4.4.1 rolling out to Nexus 5. It improves the camera with faster focusing, especially in low light, faster white balancing, for truer colors, the ability to pinch-zoom the viewfinder in HDR+ mode and less shutter lag," explains Google.
