Google has started rolling out the Android 4.4.1 update for Nexus 5, Nexus 4 and Nexus 7 LTE (2013) devices earlier today. The update is now being released over-the-air and will continue over the next few days.
As you know, all updates are rolled-out in phases, so, have patience as not everyone will get the update right-away. If you don’t want to wait for the update, download the update for your Nexus device using the relevant links given below and use this guide to update your device.
Google has also revealed that Android 4.4.1 update brings several camera improvements for Nexus 5 including 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.
The update isn’t so big for other Nexus devices like 4 or 7 LTE and mainly includes bug-fixes.
