The Camera app on Pixel handsets, also known as the Google Camera app, is getting an update to version 8.6. We can immediately say that the update will not add great new camera features. This update is more about the look of the Pixel Camera app when it opens. The update adds some Material You features and other tweaks to the user interface.
At this point, it appears that the update has not yet been widely distributed and has not been made widely available through the Google Play Store. You can check your Pixel to see when the update comes in by opening the Google Play Store. Once the Android app marketplace opens, tap the profile picture in the top right corner and tap Manage apps and devices. The screen will show if you have any apps that have received an update.

Click “view details” to see a list of the pending updates and search for Google Camera. When you see the app in the list, tap the word “Update” in the pane on the right. And that should get you to Google Camera 8.6.
Google has removed “Frequent Faces” as we noted above, but plans to bring it back in a future update. Google has not stated a specific date for the feature’s return.
