We found the Nexus 5's camera was laggy in our recent review. A new 

Google has released an updated Android 4.4.1 "Kitkat" to address the issues facing the device's camera. According to the official Nexus announcement, today's update aims for "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."

In our review of the Nexus 5, Peter M. Ferenczi took note of the phone's slow capture time:

[The Nexus 5] exhibits close to a half-second of shutter lag when prefocused. For landscapes and even posed portraits this isn’t such a big deal, but for candids and actions shots, it’s enough to be frustrating.

If you miss the shot, you can’t take another one right away. The very fastest shot-to-shot time you’ll see is about half-a-second, not bad though far from instantaneous. However, that speed is variable and sometimes runs closer to a second. The bottom line is that if you hit the shutter immediately after taking a picture, the camera will usually ignore the input. By itself, this wouldn’t be a terrible state of affairs, but in the Nexus 5’s case it contributes to the overall laggy feel of the camera.

We will download the Android update and take a look at its effect on the Nexus 5, sharing our results as soon as we can.

If you have a Nexus 5, you should receive a notification asking you to download Android 4.4.1. Android users can always check for system updates by going to Settings->About Phone->System Update.
