These dramatic LG commercials show the advantages of Knock Code (on the G3 and not only)

These dramatic LG commercials show the advantages of Knock Code (on the G3 and not only)
Ever since unveiling Knock Code for the first time (in February), LG touted it as being safer than other screen unlocking methods (including Apple’s Touch ID). Now, LG has finally made a series of commercials to show us exact scenarios in which Knock Code can better protect your smartphone’s security. There are four commercials to watch, each tying to conclude that Knock Code is better than fingerprint recognition, face detection, pattern lock, or pin codes. If you want our opinion, Knock Code can indeed be better in some situations, but not so much in others.

As you may know, Knock Code is one of the features of LG’s brand new G3 flagship smartphone, but it’s also compatible with older devices, including the G2, G2 mini, and so on.

All four Knock Code commercials are embedded below. Meanwhile, if you want to know how to set up Knock Code on the G3, check out our video tutorial here - where we’re arguing that the feature isn’t as secure as LG believes it to be (at least not when you’re using a simple code).

Cute, but gesture unlock is still the best security.

Up to 6 'knocks' with one of 4 possibilities for each knock. It's 4^6 = 4096. It's not even as safe as a 4 digit pin (10,000 possibilities, 0-9999) and definitely not as safe as Touch ID.

Can we get the correct set of rules for applying the knock code? I am sure it's not 4^6. Nevermind, LG's site says 86,367. I think that means the same quarter cannot be used consecutively.

You can actually use the same quarter consecutively.

For knock code, the number of combination is 87,376. Since you can set your knock code from 2 knocks and up to 8. Then the math becomes 2 knocks: 4 x 4 = 16 3 knocks: 4 x 4 x 4 = 64 4 knocks: 4 x 4 x 4 x 4 = 256 5 knocks: 4 x 4 x 4 x 4 x 4 = 1024 6 knocks: 4 x 4 x 4 x 4 x 4 x 4 = 4096 7 knocks: 4 x 4 x 4 x 4 x 4 x 4 x 4 = 16384 8 knocks: 4 x 4 x 4 x 4 x 4 x 4 x 4 x 4 = 65536 Then you add them all up, that'll give you 87,376 It might seem safe, but it wouldn't be hard to look at how a person knock on his screen from across the room. Honestly, the finger scanner is still safer since there is only one set of fingerprint will work, but then if it doesn't success you'll just have to break the 4 digit pin code anyway.

Samsung and others have more unlock possibilities. A 16 digit pin. 10^16= possibilities.

not trying to be that guy, but these commercials are full of misogyny. they're essentially saying lock your phone better or some woman (who are all apparently paranoid) in your life will find it and go crazy and break sh*t
