You can now enable Fingerprint Gestures in the likes of the Pixel Devices. After activating it in the menu under Settings -> moves you can use your finger to swipe up and down on the sensor to show or hide the noticiations. It’s just simplyfing the day a little bit, since you always have a finger on the back of the phone. So if you have the Nexus 5X go check it out and tell us how it works.
