Android 7.1.2 started rolling out a few days ago with bug fixes and cryptic “enhancements” for Pixels and Nexuses. One of the more visible changes you’ll notice if you own a Nexus 5X is a new option under Settings -> Moves. There’s a new Swipe for notifications toggle that enables you to swipe down on the fingerprint sensor on the back of the 5X to drop down the notifications. It’s a nice gesture that lets you check notifications without removing your index from the back of the phone or trying to reach the top of the display with your thumb.
