Whether or not the gloabl Vu will include that sensor and app combo that are in store for the second generation of the Vu is not clear at this point, but the idea is pretty nifty.
A lot of phones from the WinMo and Symbian dawn of the smartphone era included infrared sensors, which somehow fell from grace with the ascent of iOS and Android.
Best of all, LG says the sensor and the Q Remote app will not work only with LG devices, but rather with any other brand out there, which sounds very promising. Moreover, you'll be able to access the app directly from the lock screen, without getting into home screen details.
