The Google Camera app for the Google Pixel lineup of phones has a new update rolling out that brings some UI changes as well as some new features. The update is version 5.2 for those keeping score at home and has been released to the Play Store. You should see the update over the course of the next few days.
From a UI perspective, the top menu bar has been cleaned up with the grid control settings moved to the menu in the app as a setting. Given that the grid view is normally something you set and forget, this makes sense and makes the upper bar in the app a bit less cluttered.
Feature wise, users can now control the double-tap setting in Google Camera. By default, it is set to zoom on the main camera but you can set it up to switch between the main camera and the selfie camera with a double-tap. This is found under Settings>Gestures in the app.
The next big change in the app is a new notification when the lens of your camera is dirty. This feature is turned off by default but can be enabled under Settings>Advanced. For those of you who have Pixel 2 phones, you will see this new feature added to the same page where the HDR+ settings are located.
As mentioned, the update to the app has been released to the Play Store and should be hitting devices via an OTA update over the course of the next few days.
