How do I shut down or reboot my LG G6? I've been very happy with my G6 so far. It has one feature that's a bit odd - there's no power button, instead you double-tap the screen to wake it and double-tap it on the launcher desktop to put it to sleep. 

How do I reboot the phone, if I need to? And how do I turn it off? It'd be nice to do that before removing the sim card (which is on the same drawer as the SD card.)
The fingerprint reader on the back is exactly the power button. Hold it down for 10 sec and your G6 will reboot.
