Back Tap
Android 12 will bring a new feature where a compatible phone can recognize when you double-tap it on the back to complete an action like taking a screenshot, opening notifications, or summoning Google Assistant. Where have I heard that before? Oh right, just last year when Apple introduced the exact same feature in iOS 14.
Although it seems that Android will have more customizable features, like requiring harder taps, the iPhone’s double and triple taps seem to have more actions available, albeit it doesn’t work as great as it should.
