It took me a while to figure out that the Wi-Fi connection on my phone kept mysteriously turningon by itself because of some feature called Smart Mode.
There's no way to use Bluetooth to turn the unit on and off, and simple instructions for turning a Bluetooth phone into a remote control are not yet available.
Once installed on a phone, home takes over the lock screen and main display turning it into a live feed of information, notifications and images Facebook users are sharing.
Usually the scattering of energy is considered a nuisance -- whether driving in fog or poor reception from a cell phone tower -- and most techniques either try to avoid it (by turningon fog lights) or reduce the impact of scattering (by selecting energy for thephone only from direct paths).
