The new Google Camera app delivers a handful of interface changes as well as a Motion Photos and Face Retouching.
It’s said that the more advanced features like AR Stickers, Motion Photos, and Face Retouching may not work properly and Portrait Mode is not operable on account of requiring a dual camera sensor. However availability seems to be dependent on your device and APK version installed.
If you'd like to try this for yourself, you can head to the Google Camera source link below and download the APK.
