Nexus 5 - Hall Effect?

So, reading through what's now included in KK 4.4 and I was interested to see that IR is supported, and wondered if the N5 had the IR port like the G2 (see my review).

It doesn't.  But one thing caught my eye...

Hall Effect?  What's that?

According to Silicon Angle, they have it as:
Hall Effect sensor which measures the magnetic field strength used for proximity and presence detection likely used for smart covers.

So, potentially it might get one of those magnetic covers that will wake it up like the N7 did.

Cool... now you know
