Does anyone have any idea how the phone detects knocks and differentiates it from, say, rolling around in your backpack? I know the LG G2 also has a "knock detection", e.g. the phone turns on when you knock on it twice. I want this feature in one of my apps so I'm just curious about how this is done.

    I'd assume the accelerometer is able to differentiate between the sharp staccato of a rapping of the knuckles vs. the steady circular motion of rolling.

This link was posted here a few days ago. Nice looking site and vid.

The big drawback is (apparently) the app mimics your computer lock screen - i.e your computer is not actually locked, just the app has gone fullscreen and makes it look locked. Not sure about security implications?

More like a novelty item to have or showing off to your friends but other than that typing my password makes me feel more secure. Nice video though!

Is this actually a problem people have? I get that it's novel and cool, but can't fathom why I'd want it.

What could possibly go wrong.

    It has its uses, I usually leave my laptop unlocked when I'm amongst trusted friends, a layer of protection that's this quick is a great idea in my mind. I think it matters on the use case, if you're on a computer where security is paramount, don't use it, but is a convenient feature to have for a lot of other situations.

    if you're too excited you might test the durability of your screen!!
