LG changed things up a wee bit in 2013 when it introduced "Knock On" — its method of knocking on the display to wake the phone. And once you use it, it's tough to go back. WIth this year's G Pro 2 — which we'll get a look at next week at Mobile World Congress — LG's gone one further, adding some lock screen functionality into it.

Dubbed Knock Code, you'll be able to choose from a number of patterns with which you can unlock your phone. As you can see from this launch-event video from Seoul, the pattern appears to work in multiple locations on the phone, and at different scales. Pretty slick, indeed, and we'll knock to our heart's content next week.

Wish I could do that with my LG G2.

Maybe it will get added with Kit Kat for the G2

someguy01234 says:

They shouldn't do that if they want people to buy their new phones, nor release KitKat for the G2.

NoNexus says:

Why screw your customers like that? They would end up like HTC instead of Samsung

Kit Kat tastes like Jellybeans. Can't tell them apart...

I hope LG will offer this phone to everyone... not just to AT&T customers. ..

Yes ... LG Are You listening

More people would buy the LG Optimus Pro 2 ... if you would let them.

I agree. It would be easy to make a GSM version for AT&T and T-Mobile. I'd really love a GSM/CDMA version like the Nexus 5.

Wow...LG is really shaking things up...

JJ Jones says:

If this isn't brought to the G2 with KitKat, I hope someone figures out how to port it. Such a great idea.

Knock on is a cool feature and I also read that Sony is implementing a similar tap to wake on their upcoming flagship I like to see this at least as an option on more oem's phones cause I don't think I can go back to using the power button lol.

I know the saying don't usually use my power button on my G2

Be sure to wipe your screen, or your finger grease may give away all your secrets.

That applies to anyone that uses a lock code of any kind...

i like how LG and Sony are stepping it up with their high end phones this year. hopefully they can bring some serious competition to the typical common consumer market (Samsung & Apple). can't w8

Gearu says:

Too slow

That's a ton of crap to do to turn on a device. However turning it off looks useful

But compared to pushing the power button (which is located on the back of the phone) and then typing in a pin or doing the pattern? You do a pattern by tapping the phone screen.

As someone who only uses a slide to unlock when I use lock screens, this doesn't really entice me to use it. I'd rather just slide or simply turn on my device and go than do all this.

NoNexus says:

How about setting the code to be one tap...

-------------------------------------------
Kit Kat tastes like Jellybeans. Can't tell them apart...

If you can do so, that would be cool.

NoNexus says:

when I get the phone I will see, I am guessing you can. at the very least maybe 2-3 taps in the same spot.

+1

Bwahahahaha says:

Not exactly sure how that's "a ton of crap to do to turn on a device." ... I bet one could turn on the device faster doing this than you can turn your phone on hitting the power button and sliding to unlock. A competition I'd put money down on

borgib says:

LG makes some intriguing stuff, but they don't ever update them. I'm on the Optimus G Pro with no sign of Kitkat anywhere. It's a shame.

Kinda gimmicky ...

Wrong.
