My only gripe about face unlock is that it scans as soon as i press the side key even when sometimes i just want to look at the time, the widgets, or use the shortcuts. I know i can set it to stay on lockscreen
But scanning immediately means using more power even when i don't intend to unlock the device.
I wish I can start the scanning once i swipe the screen, not before that. For then, i really intend to unlock the device.
