Knock

Bringing a premium feature down to the low end

LG has decided to make its new Knock feature a standard addition to all L Series II devices. First introduced with the LG G2, the Knock feature allows you to lock and unlock the device by simply double tapping on the screen of the device. Not long ago LG introduced the G Pad 8.3 which also included the feature, and its latest inclusion was on the G Flex.

After a successful rollout with these devices, LG has decided that it will include Knock with all L Series II devices. Devices that are on the market now will be receiving maintenance release updates that will add the functionality, and new devices will launch with the feature included.

“Knock is distinctively an LG UX and a great example of what happens when you marry the latest in mobile technology with consumer-centric insights,” said Dr. Jong-seok Park, President and CEO of LG Electronics’ Mobile Communications Company, “No one ever thought that a power button needed to be improved until our engineers wondered why they couldn’t turn the entire screen into a power button.”

The update is set to begin rolling out in January 2014, which is right around the corner. Have you tried out LG’s Knock feature yet? Is this something you would like to see roll out to other Android devices, or are you content with just hitting the power button?

  LG EXPANDS ‘KNOCK’ AS STANDARD FEATURE IN L SERIESII 

Popular Feature Introduced in G2 to Make Its Way Into Key Future LG Mobile Devices
 
     
SEOUL, Dec. 29, 2013 — LG Electronics (LG) announced that its popular Knock feature (formerly known as KnockON) will be included as a standard feature in the company’s key mobile devices in the future while its line of L Series II smartphones will receive Knock through a global Maintenance Release upgrade starting in January 2014.1 

Knock was first introduced in LG G2 as a convenient way to turn the smartphone on and off by tapping twice on the display since the power button was located on the back of the phone. Then Knock was featured in a tablet for the first time with the LG G Pad 8.3 followed by the G Flex curved smartphone which also shared the rear button design of the G2. The reaction of audiences to this new feature was so positive that a version for LG’s best-selling L Series II was developed to offer the feature to as many customers as possible. 

“Knock is distinctively an LG UX and a great example of what happens when you marry the latest in mobile technology with consumer-centric insights,” said Dr. Jong-seok Park, President and CEO of LG Electronics’ Mobile Communications Company, “No one ever thought that a power button needed to be improved until our engineers wondered why they couldn’t turn the entire screen into a power button.”

LG to include Knock as standard feature in L Series II devices

I have a GPad and it's annoying as hell. Half the time it doesn't work. And it always turns on while I'm walking with it cuz my thumb is on the screen. Turned this "feature" off. Sounded like a good idea, but no.

Yeah, I can see how it would be a pain in the ass depending on how you use (and carry) your phone. But as long as the user can disable it, it's a great feature to include.

Are you serious? Nokia did this with the N9... 2 1/2 YEARS ago. Plenty of Android makers are doing truly unique and innovative things but this is not one of them

You're surprised. It's the nature of the industry. OEMs are going to rip features and ideas from each other. Personally this is a great thing. If the hardware supports it. Throw all the useful features possible. This bodes well just as the transparency pertaining to updates by HTC. This isn't something you see others doing. Maybe Moto by breaking out certain proprietary functions to the play store but little else mirrors this.
Good move LG.

Throw in all the useful features possible?

Samsung does that and it is called bloat.

Before some smarta** says it, they are useful features.

I agree. It's only called bloatware if it's something you don't find useful.

Your new here? Anything Samsung adds in is called bloat around here.

Happy Holiday's from my phone to yours...

I rarely consider OS-level features to be bloat. What I think of as bloat are carrier and OEM apps that can't be deleted without root. Anything that the use can toggle, disable or delete isn't bloat in my book.

Yeah fuck LG for trying to improve their phones! YOU HEAR THAT GUYS? ONCE A COMPANY DOES SOMETHING NOBODY IS EVER ALLOWED TO DO THAT THING EVER AGAIN! DOESN'T THAT MAKE SO MUCH SENSE TO YOU GUYS?

I have the g2 and love this feature but my sony xperia tablet z has had this for much longer. Still nice to see it on low end devices, and it is especially helpful on tablets.

G2

It's also easier to do it on the Tablet Z. It's a little hit or miss on the G2. Still love it though :P

Posted from a device better than yours :)

I can't help but laugh every time I see your picture, I don't need to read your comment I Allready know what's coming... Samsung blah blah. Pimp slap... Period.

Posted via Android Central App

Why? Because a company other than Samsung can't bring a feature from their high-end phones to their low-end? I can't help but laugh that, in nearly every comment you make, you state your opinion (which you hilariously/erroneously word as if it's fact, which by-and-large, it's not), but then don't even bother to explain why and/or back it up with any sort of relevant proof. Your comments are usually so insubstantial it's ridiculous. Seriously, *children* could find the holes and gaps in your logic.

What's even more hilarious is the fact that you seem to want to be the "Samsung Spokesperson", but are in fact doing more harm because of how absolutely fanatical you are about Samsung. If it's not branded by Samsung, you automatically call it "crap", a "knockoff" or "bootleg", or "useless" without ever seeing or experiencing the device in question. After all, you have claimed many times with many different devices how you "wouldn't touch it with a 10foot pole". What a joke.

Seriously.
This feature is on all Nokia windows phones. Its not that hard. If this is all lg has going for it, there screwed.

Posted via my defective Nexus 7(2013)

Not to mention there are any of a variety of ways to do this without touching the device.

I never understood the drool for this feature

-----------------------------------------
Happy Holiday's from my phone to yours...

Yeah. One thing that I love about my Lumia is glance screen, you pick up the device theirs the time, and once I get gdr3 it will also have notifications.

Posted via my defective Nexus 7(2013)

Dynamic notification is an app on the play store that brings the Motorola active notifications to any android phone and works really well and has tons of customization options.

Posted via Android Central App

But it doesn't have the optimization that active notifications or glance screen does. I've tried it.

Posted via my defective Nexus 7(2013)

Indeed wrong. It is on most nokia windows phone 8 devices that got nokia amber. And of course the N9 since 2011.

Posted via Android Central App

Why is there so much hate for this company? It's just way beyond irrational at this point.

Posted via Android Central App

Because, they don't support there devices well, they have a terrible history with smart phones, they have to have great devices to make up for that.

Posted via my defective Nexus 7(2013)

I agree as well. They are making some better phones now but many people like me have used LG in the past had bad experiences. I would be very wary and cautious about buying even one of their flagship devices. Granted they may improve in actually updating their flagship devices (and even a few others) but they also have had terrible customer service.
Not saying they are alone in this but they definitely upset and frustrated many in how they broke promises and ignored/ditched customers. I wouldn't dismiss buying the next Nexus as updates are going to happen but I would prefer a different company to make it (like HTC, Motorola, Sony or Huawei).

I wouldn't object to that. I'd take an HTC Nexus phone or tablet with front-facing speakers.

Posted from my "Gift from God" Nexus 5

Yes - honestly if they made the next Nexus the One with slightly updated specs and a bigger screen I would probably buy it. Was actually really looking forward to the One Max but I was a bit disappointed at how it turned out.

Posted via Android Central App on my Motorola XT890 RAZR i

I'd buy an HTC Nexus...That would be interesting.

Sent from my LG G2 (The one that works fantastic and is faster than the others)

The way it's looking now HTC won't even be around when the next nexus is released. At least LG isn't teetering on the brink of collapse.

Posted via Android Central App

I don't see a ton of hate, but the gentleman above me is right, they still have a ton to prove. Falling months behind on updates will not help. The n5 and g2 are good phones

-----------------------------------------
Happy Holiday's from my phone to yours...

Don't forget the optimus G, the nexus 4 and the G pro, they make great phones but I do agree about the concern about the updates.

Posted via Android Central App

I didn't forget them.

The N4 was a bad phone, but it also was Googles, LG just put it together.

The G didn't do much for me either way but we can throw it in...

Based on his username you should probably dismiss anything he says about nexus phones.

Love my Nexus 7
Nexus 5 is not bad but it is flawed

Nexus 4 and Gnex were turds floating in a punch bowl at a wedding

The Gnex was not that bad. The nexus 4 was the best device you could buy for under 400 dollars. The Verizon gnex on the other hand was and is total and complete shit.

A yugo is a great car for the 2k new price tag as well but that does not make it a good car

-----------------------------------------
Happy Holiday's from my phone to yours...

Yeah, its better then Samsung's TouchWiz. The software features work better on the G2 then on the S4. And if I had a G2 I'd probably do my best to cover it up.

P.S:
Is their any cynanogenmod development for the G2

Posted via my defective Nexus 7(2013)

I missed the sgs4 so I cannot comment on it much. The sgs3 and note3 did not disappoint in the working features department

-----------------------------------------
Happy Holiday's from my phone to yours...

Honestly, this seems like a really stupid feature. I'll take active notifications and its battery sipping way of only lighting up part of the screen over this, thanks.

He is right though, the original guy, that amoled is more efficient for this feature.

-----------------------------------------
Happy Holiday's from my phone to yours...

Yup. I love amoled displays because they have truer blacks and can shut off pixels.

Posted via my defective Nexus 7(2013)

True, amoled is more efficient, but he said it's only possible with amoled which is false.

Posted from my newly Kit Katted Droid Ultra

It's possible with any type of screen, but it's most effective with Amoled screens.

Posted from my "Gift from God" Nexus 5

Can't complain about or challenge a tangent you started or were involved in - other feature was mentioned so others picked up on it... Simple as that.

Posted via Android Central App on my Motorola XT890 RAZR i

If Samsung added this they would call it like LG knock on
But they would call it hard-on lol
Sorry for being immature I couldn't help it

Sent from my Nexus 7 2013 or Moto G

I wouldn't worry so much about being immature as I would about that comment making no sense at all if I were you. Lol

Posted via Android Central App

Knock would be nice to have on my Nexus 5 and Nexus 10. It would make things easier since my fingers don't work so well for pressing buttons.

Try gravity screen or dynamic notifications with the proximity sensor turned on

-----------------------------------------
Happy Holiday's from my phone to yours...

Gravity screen is an amazing app!!! I used it for about 3 months before I screwed it up and the screen was turning itself on randomly and staying on wasting my battery. I never found the time to redo all the settings, so I haven't reinstalled it since. If you haven't tried it, you definitely should. It's a cool app to show off to your friends. When I'm showing off cool android stuff like that to people I usually finish with 'and that is why you root a phone'

My name is Richard Yarnell and I approve Samsung products.

Sent from my Note 3 rockin Jelly Bean 4.3

in a perfect world, this would also power your device on, and that would put us one step closer to a device with no physical buttons at all!! It wouldn't be difficult to create software buttons to power down/reboot and change the volume (several apps already do that), so a power on feature is really all that's left to realize that dream. How cool would that be?

I thought it was just a gimmick when I picked up my G2 but I love it... The only problem is I keep trying to knock on my Nexus 7... Its a great feature that I would love on all my devices. Knock Knock! so what if sometimes its Knock Knock knock...

I'm glad I'm not the only one...Coworker was showing me his S4 (yes, seriously...he just got it) and I tried to knock it on, and he was all WTF?!?

This. Love tap awake on my 920 and 1520. LG not doing anything innovative here. Just taking a note out of Samsung book. With that, their phones lately are nice, but I would never invest in one.

Stolen from NOKIA's glance screen... Microsoft got it from nokia which had it deployed years earlier.

Posted via Android Central App

No one said LG was doing anything innovative. Its just cool that they're adding this feature to existing devices, in addition to they're latest 2 devices. Hope they make it compatible with the GPE.

A lot of haters around here.

Posted via Android Central App

I welcome the Knock feature, but I want it on every device I own, not just LG. I can't count the number of times I have double tapped the screen on my tablet or laptop and been disapointed...

i have the LG G2 and i love knock! Every device i hold i try to 'knock' on the screen! it works well you just have to find the sweet spot where it works best. on the phone thats in the middle, top third of the screen. once you get used to it, its second nature and brilliant. i wish my Nexus 7 had it

Posted via Android Central App

i have knock/knock on my find 5 ..though not on the screen but on the homebutton...to put screen nack to sleep...swipe from left to right on buttons...take that to the bank

Windows limits has had this feature forever. Where is all the oooooo's and ahhhhhhhh's then. Just saying. Love both platforms.
