Google has updated the Camera app to version to 3.1.021 for devices running on Android 6.0 Marshmallow. The updated app brings additional features and a brand new user interface (UI).

Google first released the Camera app on the Play Store in April 2014. Google updated the Camera app with a new UI and it was available by default on the Nexus 6P and the Nexus 5X smartphones. Now the updated UI will be available to all devices running on Android 6.0 Marshmallow.

The updated Camera app will allow easy switch between still mode and video mode just by flicking the screen right and left. Previously, this was not allowed and flicking right and left opened the user's gallery. The button that switches from rear-facing to front-facing camera is also now located next to the shutter button.

The updated camera also introduces the Auto HDR+ feature to the Google Nexus 6. The Auto HDR+ adjusts the exposure in the picture to provide consistency.

"Use the HDR+ (High Dynamic Range + Low Light) setting to improve images captured in low light, and backlit scenes," per the Play Store.

Android 6.0 Marshmallow device owners can now re-focus the scene while taking a video by tapping on the screen, instead of capturing a still image in the previous version. 

The upgraded app also brings a fix for the Nexus 6P's Smart Burst issue, which did not allow users to take burst images at all when it was disabled. 

Google is rolling out the Camera app update to users in phases and owners should get a notification when the update is available for download.

Customers who have an Android device running on previous version will not see any changes to the Camera app. Android 6.0 Marshmallow is available only for a few smartphones, which means currently only a limited number of customers will be able to experience the new UI and features of the app.

The Camera app is available for free to all Android devices running Android 4.4 KitKat or above from the Google Play Store.
