[Q] KnockOn with Nova Launcher?

All,
I just installed Nova Launcher and noticed I can double knock to wake the screen to get in, but it seems like I have lost the ability to double knock to put the device to sleep. I have to double tap the top navigation bar to do so.
Anyone have this same issue?
Thanks!

I don't use the Nova launcher but I've got the double tap to wake from a kernel.
I can't double tap to sleep from anywhere, I need to be in lockscreen for that to work. Think of one playing flappy bird...

It's a different launcher, so its wont have the stuff LG put into their launcher by default. You can set the double tap action in nova launcher by going to the nova settings > gestures > double tap
I dont think there is a native way to link the action to locking the screen, but you might be able to bind it to an app that will lock the screen.

you can make nova double tap status bar to lock screen. thats what most people have done.
I myself havent moved off the stock launcher yet, it is nice.

There's a simple solution to this. Download 'Screen off' from the play store and then set double tap on Nova's gesture settings to open 'screen off'
Et voila

The G3 TweaksBox has the option to add knock to the lower navbar as well.

Similarly I use "Soft Lock Screen" app which does the trick smoothly in Nova; install it and assign to double tap nova action, that's it!

[Q] Nova ui, how to double tap screen off?

I like the stock ui feature of turning the screen off by double tapping. Does anyone know how to enable this feature under99th the nova ui, or a similar ui that has this feature..

I'm using Nova, and the double tap works by tapping on the Status Bar.

Install the following app and configure the double tap in nova gesture to open it.

I made double tap activate my greenify+lock screen as an alternative

This works great thx

News:
Now Nova (prime of course) offers the knock off feature without any other app needed.
Look on gestures!

Like leon said, nova now does screen lock in gestures.

I'm trying this functionality.
I've smart lock with my smartwatch and I double tap to let the screen off when I double tap to turn it on it will ask me for pin.
Instead if I wait for time to screen off, when I double tap to let the screen on smart lock works.
Strange, I will write this to Nova...

Launcher that allows Knock On/Off

okay, so the G6 is pretty sweet. debloated it, installed Nova (LG's three launchers are pretty terrible, especially that cheesy "stretch" effect), everything is pretty much how i want it (not Rooted), except: Nova Launcher doesn't allow Knock On/Off.
i can dbl tap to wake, takes me to the lockscreen. fingerprint reader is whipsmart and FAST, so this isn't so much of an issue. but without Knock Off, i have to wait for the screen to time out OR press the power button. workarounds: tap the thin notification strip at the top twice -- which is hella awkward, when i have this giant screen; or install a 3rd party app -- which kind of nuts when the phone natively supports this functionality.
anyone know of an alternate launcher that won't inhibit LG Knock Off?

This works fine in Nova, but you have to be rooted. I don't think it is Nova fault, it is just like this in Android.
You can actually try to enable this action in Nova's settings, there is some workaround when you are not rooted, but it won't be same...

Nova has this feature if your rooted, if your not they have a similar one, you double knock to turn off but puts it in standby until your auto-lock kicks in.

I double tap the notification bar with nova not rooted and it works fine no matter what app I have up. Unlike all other nova gestures that only work from home screen.

sounds good ... i'm assuming this is something that can be done with gestures enabled, with Nova Prime?

it's what i'm doing right now -- and i like that, as you mentioned, the functionality is available on any screen. but it's awkward for single hand use. didn't know that Nova gestures only work from the home screen. hmmm ... that's also a consideration.

Yes Nova Prime, Gestures, Double tap.

just upgraded to Prime, tried this. doesn't quite work the way i thought it would: double tap turns the screen off but it also disables the fingerprint reader? (!!) so i then have to tap the screen -- which doesn't turn the screen back on, but instead shows the faint outline of nav icons at the bottom. if i hit the home button, then screen comes back.
that's some weird behaviour just to get something like Knock On/Off. no root for the h870DS, so it looks like i'm stuck for the time being ...

I went through the same thing, trying a bunch of different solutions. Not being rooted and on 7.0+, nothing works (hopefully something will work on 8.0+).
You'll get used to using the power button in the back, and tapping the status bar.

i'm resigned to this, hope so. can't live with that LG launcher, when Nova is so much more functional.

Nova works without root. Double tap(knock) on notification bar to sleep. Truly had nothing to do with nova it works with all launchers. Tried 3

I have the double tap gesture in Nova launcher that locks my screen so it keeps the Knock feature.

Can confirm, i have the lawnchair launcher and was missing the feature, double tap the status bar and it works no mather where or with which launcher.

So nothing works so far if you're not rooted?
I remember Nova asked me to choose between two option for double tap to lock when I set the gesture but I chose the one that just turn the screen black and wait for system lock. Really bad. Not sure what was the other option.

The other option Iocks the screen instantly but disables the fingerprint reader for the next unlock, making you enter your PIN.

Awful.. Thanks for the info. I guess I'll have to disable fingerprint and just unlock with swipe and lock with double tap on the status bar if i want to keep using nova.

Double tapping the status bar works perfectly though. Keeps the fingerprint active. It's just when you activate Nova's double click the home screen that it gets wonky.

Double tap on status works fine for you with fingerprint and without asking for pin?

Silly me. It failed to read my fingerprint and asked for the pin. Works fine now. Thank you.

There you go! ?

Have tried using fringer print to unlock? Ive forgotten knock on now

There is a quite good workaround for those who are using Tasker. Together with TouchTask plugin (free in Google Play) you can simulate double tap on notification bar to lock your phone. This way you can unlock the phone with fingerprint without need for entering PIN or pattern etc.
Short instruction:
1. Download and install TouchTask. Give it necessary rights in Settings.
2. Create task in Tasker > Plugin > TouchTask.
3. In TouchTask Configuration menu:
In Actions field select TAP
Leave Selection method set to Point (x,y)
Type 716 16 within Selection point field
Set Number of taps to 2
4. Assign an icon to your task in Tasker
Now you can assign your Tasker task to any available gesture in your 3rd party launcher (i.e. double tap in Nova Launcher). After executing assigned gesture your phone will be locked exactly in the same way as if you were to double tap on the notification bar. This way fingerprint works like in LG stock launcher - no need to enter PIN or Pattern after unlocking phone with fingerprint.

Off-Screen gestures

Since we can double tap to wake the phone, will it be possible to add other gestures via a ROM or kernel like on the op5/5t?

Actually, I meant like to control music by drawing a gesture on the screen while it is off.

Is double tap to turn off screen possible

As the title suggests is it possible to double tap on empty area of Home Screen to turn the phone off just like we use Double tap to wake the phone.
This was an inbuilt feature on Asus Zenfone 5z and seems counter intutive to have only one option to turn the screen on and not off here.
Regards

One option; with Nova launcher

Yes, likely via custom ROMs.
Also, probably via custom launchers. Nova Prime allows double-tap to "lock screen". Double tap to "screen off" very likely via a specific 'Nova activities' option but I haven't figured this out yet.
EdXposed ---> install GravityBox ---> it's then possible to turn screen off via double-tap on lock screen or via double-tap on status bar.

You can use edge screen. SoftKey Edge. There is a lock option. It is not double tap but it works.

you can add the screen off icon at navigation bar with a samsung app called Navstar, with that you can single tap to turn off the screen

Good Lock - Navstar adds a navigation button to turn the screen off

I dont see any gestures for that in nova launcher?

You must have the prime license, in gestures&inputs there are multiple options to choose from, for each gesture you can choose any action available, you can even have the same action assigned to multiple gestures, I use one finger down to lock, and also double tap to lock

As i already have Nova prime, this worked perfectly. Thanks.

Nice just learned something new. Used nova star and added screen off and notification bar button. Now I have 5 buttons readily available.
Wish you could open and app with a button. That way I can reserve the power double tap for another app.

Feeling seriously numb right now. I've used Nova (Prime) for years, and never knew that was there. Searched all over for a good program to sleep/ lock. Found a very simply one (Screen Lock Widget 1.0) which is no longer available, but I have. Works great. No resources used. But having the ability in Nova is great.
So.....thank you for sharing that. It's the simple things in life.

It makes no sense why Samsung would give us the means to tap awake our screen but not add that option to turn it off.

That was a weird decision for not including double tap to sleep. It's like making an automatic car with clutch where the clutch is only used for the reverse lol.
Anyhow, this is by far the best app on the playstore that can put the phone sleep and still use the default One UI.
The nice thing about it is that you can also tap on the status bar to put the phone to sleep while using an app for instance.
Tripe tap on the home screen is recommended though, you'll understand why after using it for a while

That is very interesting, I never use always on display and it seems like the Note 10 has a lot of issues. For instance Samsung voice recorder app doesn't play recorded audios while the screen off( stops playing after 2min or so).

I just tried Nav Star app from within Good Lock (From Samsung App store) and added 2 extra buttons.
Thanks to the user who recommended it earlier, now I can turn off phone as well pullbdown notification bar from the Navigation bar, if I can get used to these extra buttons I might as well keep them.
Yes software wise they do need to improve a lot of things here.
1. First Install Good Lock :
http://apps.samsung.com/appquery/appDetail.as?appId=com.samsung.android.goodlock
2. Then Install Nav Star : http://apps.samsung.com/appquery/appDetail.as?appId=com.samsung.systemui.navillera

Well, very useful indeed, but I prefer hiding the nav bar, just to avoid screen burn in and to get some more screen area
