It appears that Google’s flagship tablet – the Nexus 7 – actually has a tad magnetic sensor that is hidden under its display. The said feature, which can also be found on other devices, triggers the display to turn on once an external magnet is removed. This works well when you are using a case that also has a magnet on it, quite similar to the iPad’s Smart Cover which puts the tablet to sleep when the cover is closed. If you want proof of the feature, check out the video above to see it in action. So, judging from this unexpected discovery, it appears that the official case for the Nexus 7 tablet will finally put the magnetic feature to full use. It is interesting to note that iFixit, who did a thorough teardown of the device last week, wasn’t able to spot the said feature.
