Screen off Knock Code! wow - LG G6 Guides, News, & Discussion

Something interrestung i just found on my G6. My device unlock method is fingerprint + knock code as a backup unlock method. Turns out that Knock code works also when my phone's screen is off. All i need to do is just tap the code anywhere on the turned off screen the same way i do it on the knock code squares when my screen is on ( imagine those 4 tapping squares anywhere on turned off screen and just tap your sequence) and voila.
Don't know if any of you guys know about it, but give it a try if you want and please confirm if it works like that on your devices too

So sad to know that you discovered it now. I'm using it since the day one I unboxed the phone. It's the patented feature of LG.

I always thought that in order to unlock your phone with knock code you first had to double tap the screen to wake it, then swipe it to get to knock code screen, put the sequence in and then you would see your home screen :/

I just checked it and it does work with the screen off ?. Nice feature though

I had this on my G2 soo...

This wasted time.. ?
I use fingerprint when I have the phone in hand, double tap + slide the screen for the house (auto unlock with position) or knock code outside my home when the phone is on the back
Yet the phone explains the operation during the first setting I believe !?

This work only with the Lg Launcher?

If the screen is on, double tap only works on LG launcher. Or doesn't matter what you use when the screen is off. Just tap in your knock code and it will unlock.

Drifting from the topic but actually double tap for screen off works partially for any other launcher as well, you just have to double tap the notification bar on the top. It is sometimes hard to hit especially with big finers as mine but it works.
I forgot to say that this actually works not only on the homescreen but on any screen or app you are.

double tap to sleep work flawlessly in Nova launcher with Tasker.. without any root btw

[Q] How to remove remove slide to unlock screen with finger print unlock?

The method with slide to unlock is redundant and annoying. How to remove slide to unlock?
I'm in the same boat.. every time I try to turn on fingerprint unlock, I still have to slide to unlock.. I'm missing something here..
I don't get it. When you have finger print as your unlock method there is no slide to unlock. They are mutually exclusive, you can't have both.

I have experienced the Slide to Unlock screen when I have a paired bluetooth device that I have listed as trusted. I think this is what these guys are talking about, and it is annoying. I wish it would just unlock to the home screen.
I think you should upgrade to latest firmware, i never got slide to unlock screen when i use finger screen function!

Slide to unlock shows when you use the smartlock feature to keep your phone unlocked. It's there to prevent you from butt dialing someone.
Go to secure lock settng > secure lock time and set it to instant.
That way every time u lock your phone it will ask for finger print and will unlock right away

This man probably has it, your phone will not go to the lockscreen when fingerprint security is checked unless you enabled trusted devices and are near one. It should in that case simply go to the home screen as it does on most devices when similar schemes are enabled but it instead switches to swipe to unlock making the whole thing not only pointless but more work then never enabling trusted devices at all.
Its either a bug or stupidity, hopefully they get it changed.
Make sure you don't have any trusted bluetooth devices set up. If you do, you'll always have to swipe whether fingerprint authentication is enabled or not.
Aha!

Ha- that actually does work as a workaround, but sorry... What I want (and think OP is after) is to just turn off the swipe.
If the phone if unlocked, show me the home screen.
I want to take the risk of the buttdial!
Use case- pick up unlocked phone, press the side button, see home screen. Not swipe to get to home screen.
Don't know if that's a feature request or a rant or just a bit of both.

I tried to use No Lock Home module for Xposed instead of built in Smart Lock. But it doesn't eliminate Swipe to Unlock either.
I had my S6 set up to just require a pattern to unlock. Worked fine for the first 6 months I owned it. But since I allowed Samsung to upgrade my software, a swipe is needed before it will allow a pattern unlock. This happened to my wife's phone too. Thanks for the ****ing annoying "upgrade" Samsung.

Only after a reboot. First unlock after a reboot has to be PIN. Then after that fingerprint works normally. Was always this way before the update though.
Yep. I had to stop using the double tap to screen lock gesture on Nova. Guessing Samsung doesn't want 3rd Party apps to have control to lock the screen.
Man, that sucks. Hope Nova tweaks it for us. I feel like I'm going to wear out the power button, not to mention it's easier to double tap to lock

YES anytime the phone locks you have to use fingerprint and PIN. Good news is you can get rid of the lock screen and still use samsung pay with fingerprint. They need to fix this AND issue and soon though
I'm still unable to use fingerprint to unlock my device. Nova double tap working fine here

This is why I don't use a secure lockscreen. It causes more grief than anything else. I'm honestly surprised that Samsung lets you use Samsung Pay and other fingerprint features without a lock screen. Every other device I have used wipes your fingerprints as soon as you turn off the secure lockscreen. I usually just do without.

Nova and screen lock widget?

hey, I was trying to get nova and screen double to lock phone, but it doesn't work since pin will be required. and i would need root.
But huawei already has a widget screen lock that only works on huawei launcher... and when i try to make double tap trigger than widget, i get app is not installed or permission denied. can anyone know how to get it to work? or any app that makes fingerprint work with triggering screen lock?
Thanks
I have send a mail to Nova support but didn't have an answer yet. Too bad that this isn't working on Mate 10 Pro.
I have same problem, anybody have solution for this?
i've the same problem too

I'm not exactly sure what it is that you're trying to do but... I have the Mate 10 (non-pro) and I use Nova Prime and I also have double tap to lock set up and it works just fine. Now there are two choices when using it from Nova. One choice locks the screen immediately which requires a pin/password to unlock... nature of the beast. The second choice will turn off the screen immediately BUT you have to wait 5 seconds for it to lock the phone which does allow the fingerprint scanner to unlock the phone. So, not sure what you are trying to accomplish but I hope this helps! :fingers-crossed:

only problem with that method is if you touch the bottom of the screen where the keys are within 20 seconds the screen will wake up even if in your pocket

OK, I definitely don't like that option of 5 seconds because if I want to unlocked immediately it doesn't work, anyway, I have a question, you said that use nova prime and the double tap gesture with the action of screen lock, enables you to unlock with the fingerprint? Or a PIN is required?

Pin is required!
A pin or password is required if you select to Lock Immediately upon double tap. This is an Android thing that for some reason cannot be bypassed...I do not know the particulars. But the other option, where you need to wait a little over 5 seconds after the double tap...will allow the unlock with the fingerprint. I have been doing this for years on various phones and it works quite well. You do not have to wait 20 seconds...however, during the 5-6 second wait period you need to leave the phone alone... do not move it...or if you do move it then you need to be as careful as you can not to activate one of the motion sensors, or touch the screen. So then, let's say you have it set to the 5 second lock and you double tap to lock and you need to get up right away and move...then if you are careful not to touch the screen and not swing the phone like a madman, then it will still lock after 5 or 6 seconds and the fingerprint scanner will unlock it as expected. The best use for this method is when the phone is sitting on a desk and you double tap to lock and leave the phone just sitting there for those few seconds. It's not "exactly" what you want but it's better than any alternative at this point.

10 seconds, 10 interminable seconds!
This software is ridicule...
I have timed it on my Mate 10 (non-pro) and it takes 6 seconds to completely lock. You can move the phone around during these 6 seconds but should not touch the screen and it will lock. Not much else you can do as far as I know. Again, this an Android thing, not anything to do with Huawei, or Nova.

Not exactly true.
If you need unlock the phone during those 5-6 sec, just touch the screen in the position of Home button on navigation bar twice and the home screen is up again, since it wasn't fully locked yet.

I have a Huawei Nova 2i & was looking for the same. Go to Smart Assistance & activate Floating Dock.
Root is the only option if you want the double tap to sleep to work as you want. Sucks.

Double tap to wake/sleep

Does anybody know a way to enable double tape to wake/sleep?
Instead of double tap, long press on the bottom of the screen where the home button would be if the screen were on. There's no built-in double tap to sleep, but some third party launchers (like Nova) have implemented a work around. But it only works on the home screen.
The home button method is lmag, but still not great. It's nice to be able to just tap any part of the display and for it to wake up. That's one thing the iPhone definitely got right this time around compared to S9+

Implementing this feature will probably add battery drain as some sensors need to be active all the time also a custom kernel could implement it. Wait and see

It can be an option.
The S9's "always on" home button requires a sensor to be on all the time, too. But the SD 845 has a very low power mode to support these sorts of things. I don't think double tap to wake would use any more power than Samsung's approach. But I'm happy with Samsung's approach, but I wouldn't mind a double tap to sleep, like my old G3 had.
ElementalX has double-tap to wake.

Well, sort of. One, it doesn't really put the phone to sleep instantly. What it does is reset the screen timeout to a very short value, so the screen goes black. Then, after the phone really goes to sleep, it resets the screen timeout in the background. Two, you can only do it from a Nova home screen. In LG's implementation, you could tap on the status bar on any screen to put the phone to sleep. (Or maybe it was the Nav bar. It's been a long time since I had my G3.)

Yeah you are correct on both. LGs way is anywhere half way down the lock screen could be double tapped to go to sleep. That's what I'm looking for. Just grabbed the s9 and I miss the dttS on the ls. The double tap on home button isn't too bad I suppose but still also miss the full screen dttW from LG.
if you have the home button showing on always on display you can double tap it to wake(instead of pressing it hard) just double tap it
If you use Nova Launcher you can use the double tap to turn off gesture.

This douple tap feature was available but it stopped 2 days ago. I don't know why or how to set it again.

Way to lock screen (unrooted)

So I have a LG G7 One which runs stock Pie. Sadly LG's knock knock features aren't included. Bootloader is locked, so no root options currently. This my first phone that doesn't have a root option. I feel a little limited.
I'm looking for a way to lock my phone without using the power button. Ideally double tap to lock. I've tried a few different options but they all seem to have the same limitation. They force me to use my pin after I lock my phone with them. Something about my phone being locked by admin. I would like to just use my finger print scanner. Is there any workaround for this?
I'd prefer double tap to lock, but I'd settle for a quick settings toggle. Are there any apps that allow this? And would I face the same issue, where it forces me to use my pin afterwards?
I have pixel launcher on my V35. The LG double tap to wake/sleep works but only when I double tap in the notification pull down. Near the top. This is still the LG feature so maybe not good for you. I thought stock Android had the double tap thing tho. Maybe not Android One?
