So apparently the Nexus 7 tablet has a little magnetic sensor hidden under the display that can trigger the display to turn on. Not exactly a new phenomenon, but interesting because until now, it's a feature that's gone unmentioned.
The way it works is you have a cover or case that also has a magnet inside, and that second magnet lines up with the corresponding spot on the device. Remove the second magnet, and the phone says, "Hey! I'm alive, and it's time to wake up now!"
Again, these are not new. Not now, not with the iPad's Smart Cover. We've been using them long since the bad old days of Windows Mobile. And it's a staple on BlackBerry. (Anyone remember when software could actually screw up this sort of thing?) But it leads us to believe we'll see that feature arise again in the official Nexus 7 case from Google, and probably in the ones from ASUS as well.
There's video after the break if you need videographic proof of this force of nature.
Here's the real question, though: How the hell did iFixit, which can spot the serial number on underside of the world's smaller circuit board, miss this one? Good thing we mentioned the magnetometer in our Nexus 7 review, eh?
