Google Pixel 2 owners with the Android Oreo 8.1 update received access to Google’s AR Stickers last December. Using Google’s ARCore technology, the Pixel 2 lets users insert R2-D2, Stranger Things characters and other animated characters directly into their surroundings. Now, through Google's free Motion Stills app, any Android phone with a built-in gyroscope and running Android 5.1 or higher will have access to similar AR tech—it just doesn’t use ARCore.
