    We aren't sure what possessed the Google Nexus 7 Tablet owner in the above video to start tinkering around with magnets on his new device, but his curiosity seems to have paid off. Apparently, he found a potential feature of the device that was not documented anywhere previously. The Google Nexus 7 may have a magnetic smart cover sensor built into it. If you take a magnet and put it against the front or back of the Nexus 7 along the bottom left-hand side (while in portrait mode with the display on) the device will automatically turn on. You can check out the effect in the video above. Is this a hidden feature, or something else?

    Placing a magnet near the phone or pad may do damage only to things such as the built-in compass by "magnetizing" or "demagnetizing" the device, and even that's a possible non-issue since the compass in these devices is a solid-state device. Otherwise, I don't believe it would be an issue.

    In the earlier versions of the Droids, D1, D2, and possibly later models, there are 2 sensors on the back of the phone that detect which of were used to determine if the phone was placed into either the navigation dock or the home multimedia dock. The docks each had one Rare Earth magnet placed in one of two unique specific locations on the docks to alert the phone to the dock.

    They did no harm to the phone.

    Also, it's a common way to attach the fold-out covers to iPads and other pad-type devices.

    There are issues with bringing magnets near Cathode Ray Tubes (old-fashioned picture tubes as used in pre-LCD/LED TVs, monitors), and also near Plasma TV screens as the effect can be a permanent discoloration of the display. LCDs, LEDs, OLEDs are immune to this (AFAIK).

    ahh, maybe its really pc's that magnets are bad for
    although i do see a magnetic smart cover sensor being a problem in some cases (no pun intended) for tablets and especially phones (if they ever decide to do that too). What if someone decides to use one of those cases or covers that use magnets to stay closed or attached? it could very well keep waking the phone or tablet up and kill battery life

    Don't most tablet/phones have this feature anyways? Usually for multimedia docks like previously stated, its just a magnetic proximity sensor..

    A lot of phones have magnetic sensors/switches.
    Ones that I've owned include the Touch pro 2 that had one that changed the screen to landscape when you opened the keyboard, the Droid X has one on the back that tells it when it's been inserted in a dock etc etc.

    I can't believe my video created this amount of frenzy. I guess 15 minutes by magnet is better than no 15 at all?

    Partly right there. You don't want to put a magnet near a PC with a regular hard disk in it...could end up damaging the data on the disk. This is a non-issue with solid state drives and other internal PC components.

    Do they all work the same way as this though?
    I don't think the galaxy nexus does (I went ahead and tried it just for kicks)

    The Googleans may have inadvertently caused the Apple Empire to hone in on their peaceful world in an attempt to destroy the planet Nexus 7 because their technology may rival their own. The Appleans will not rest until the Empire has control of the Galaxy, the High Technology Council (HTC), the Motorola Expanse, and all Nexus and pre Nexus like planets. For Nexus 7, removing the planets magnetic poles will surely be the beginning of a new war.

    Yes it's true the nexus 7 has a feature that when you put it in a case with a magnetic cover it turns off the screen, it even makes a shutter noise when you close it
