Bug description:
  NOTE: kgunn suggests this bug be about 1) not 2) here

  I have been noticing my phone and tablet occasionally turning on without interaction. Several times with my phone in my pocket I found it in the emergency call UI
  I also see the tablet display turn on while lying idle on the desk. Freiza & Arale

  I have reproduced one case such that turning on a BT device (headset) causes the phone to light up and display the volume slider. Similarly turning on the BT keyboard while the tablet screen is off caused the display to turn on.These may be as intended.

  I suspect other BT events can similarly resume the device and/or turn on the display if it happens to be awake due to the 5 min polling timer.
  The proximity sensor is also not honored when this happens, if its covered the screen still comes on.
