Nexus phone request. Can we eliminate the Power button? With things like LG's Knock-Knock, Moto's Always listening and in my case, just using the Prox sensor and/or Accelerometer and tasker, there is really no need for the power button in normal use. A simple hidden reset button, maybe under the back cover, is all the phone needs for wake-up and sleep.
I would like to see the volume buttons go away too. I'm sure there are other ways. One idea is use a swipe gesture on the non-screen part of the glass near the ear piece. Another is capacitive "Trackpad" on the back cover in a similar location to the LG G2 buttons. This could do more then just volume.
I just think a buttonless phone is one less thing to break, and offers a more sexy design.
If you haven't tried it, I suggest you do. Simple Tasker profile to use the prox sensor to turn on/off the screen. There is an app that does it too. It's really nice to not have to press the button when you pull the phone out. Worst case it you have to put it near something, like your leg then pull it back again.
With a separate processor to eliminate false triggers, etc this could be done in a low power way, the way Motorola has the gesture and voice processor.
