When Snapchat first hit it big, people just assumed it'd be used for seedy activities. And while that's not completely true, it's definitely true sometimes. For those moments when you need to take a sneaky screenshot that doesn't notify the sender, Android has plenty of ways to keep your cover from being blown — no root needed. For this to work, speed is the name of the game. Taking a screenshot is probably second nature to you, but toggling Google Assistant may not be. So be ready to call upon it before the Snap disappears.
