How To: Don't Wait for Google—Get Night Mode Right Now on Android Nougat

It's now common knowledge that the blue light emitted by phone screens makes it harder to get a good night's sleep. Apple's Night Shift in iOS and its steamrolled predecessor, f.lux (still available for desktop computers), are attempts to combat these harmful effects by limiting the amount of blue light from the screen at certain times of day (nighttime, say).

How To: Lock Your Android Easier & Faster with Just a Swipe

Unless you're sporting an LG G3 or a mod that allows tap-to-sleep and/or tap-to-wake functionality, you're probably hitting the power button to sleep and wake your device. But that button may be awkward to hit, may be worn down, or may just stop working due to a manufacturer's error or a device drop.
