Last month, LG unveiled its flagship handset for the second half of 2013 – the G2 – with some unique features like QSlide and KnockOn. The latter is a very interesting feature since it allows users to wake up or put the device to sleep by simply double tapping on the screen.

With Android devices getting better, the ability to wake up or lock a device by simply tapping on the screen makes more sense. A kernel developer for the HTC One – tbladen – has gone a step ahead and actually introduced two very unique and handy features, Flick to wake and Pick to wake. The former allows users to wake up the One or put it to sleep by simply flicking the device.

Pick to wake, is perhaps the more interesting one, and will automatically wake up your One when it is picked up from a table and held vertically for a second or so.

The only problem is that both the features come at the expense of battery life. While the hit on battery life is marginal when using flick to wake, there is a substantial battery life hit when using pick to wake, since the CPU needs to constantly wake up from the sleep and check the readings from the sensor.

With the Snapdragon 800 coming with an integrated Sensor hub, we might just very well see next-generation Android devices incorporate such features right out of the box, without any effect on battery life.

Head over to this XDA post, if you want have an unlocked bootloader on your One with a custom recovery installed, and don’t mind flashing a custom kernel.
