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.)
