How To: Lock Apps Using Your Samsung Galaxy S6’s Fingerprint Scanner

Like its predecessor—and probably every device in the future—the Samsung Galaxy S6 comes with a fingerprint scanner that allows for a more secure lock screen, web sign-ins, and account verification. But unlike its brethren, the sensor on the S6 has been vastly improved.

Many others are optimized for multiple languages, space saving, or emojis, but none are without their flaws.

Normally, if you want to close all of the open apps on your Mac, you'd have to either quit them all one by one or restart, shut down, or log out while making sure to deselect “Reopen windows when logging back in." The latter option is great, but it doesn't always work in Mac OS X, and what if you don't want to restart, shut down, or log out?

How To: Bring Back Airplane Mode & Audio Toggles to Your Nexus 5's Power Menu

In an effort to make things simple and more secure, Google decided to slim down the power menu in Android 5.0. What once provided a quick link to shut your device down, turn on Airplane mode, and toggle volume states, has now been relegated to a simple power switch.

How To: Entirely Replace Your Android's On-Screen Navigation Buttons with Gestures

Add to that the fact that they're far less likely to fail and can be themed or even switched out altogether, and it's hard to come up with an argument in favor of physical b...
