Alternative launcher can't lock screen ? - LG G6 Questions and Answers

Hi everyone!
I found this very annoying problem with my LG G6 when I use an alternative launcher and I activate the gesture double tap to lock screen the phone show me a message with write that this option is not allowed !
Nova launcher have a smart solutions like turn the stand by at 5 sec after the double tap ...it's work but not best solution in addition not all launcher have this options...
LG G6 have in stock the options double tap to awake/sleep ... Why launcher can't works with this ?
I really want fix this annoying problem I hope without root ...
Thanks in advance

I don't have root and use Nova and can unlock my phone with a double tab.
Have you made Nova a system administrator?

Well I think no ... If you don't have this problem.. could you please tell me how do this? Thanks in advance

I wish I could, but I've never had this problem - I've used Nova for a few years, starting on my G4 and it has always just allowed the double tap function, and no different on my G6.
I'd start though by going into the Phone Settings screen > Fingerprints and Security > Phone Administrators and enabling Nova Launcher as admin. If that doesn't work, I'm out of ideas.

I tried your solution but now there's another kind of problem if I activate permission I can't unlock the phone with the sensor finger print ! It's unlock only with pin
Do you have the same ?

Do you use free or paid version of Nova Launcher?

I use the pay version but I have the same problem with all alternative launcher tsf shell for example...
I'm really the only one ?

Are you sure it isn't just asking you to unlock with a PIN for the first time?

I found this post, don't know if it will work not using Nova right now Quote: Go to gestures and click double tap to lockscreen and then choose root. It does work. If your having problems or dont have root, choose to set it as an administrator.

I already set like an administrator but it doesn't work ...

No it ask me everytime I lock with double tap

I found another strange thing .... When I lock phone with double tap on status bar all works perfectly..when I lock it doing double tap in other point of screen it doesn't work ...

Only remaining ideas I have then are to clear the data and the cache of Nova, then uninstall it (as well as any other Nova related apps you have like Tesla, Nova Prime etc). Reboot the phone, then reinstall Nova from the Play Store, then (if you have it) reinstall Nova Prime from the Play Store too.
Press the Home button (circle on the bottom of the screen) and when it asks you which launcher you want to use, select Nova and open it to then go through all the settings. Make sure you allow any permissions it asks for, and follow through with the set up. Then, once that's all done, make sure you make Nova an administrator as per my earlier post.
Hopefully that'll work!

Here is workaround for Tasker users:
https://forum.xda-developers.com/showthread.php?p=73462212

I read on the web that this annoying problem it's made because a security level introduced nougat that not allow to app to lock the screen ...
Anyway thanks to kulvetti now I solved this problem ! The solution using tasker it's perfect!!
Many many thanks!

Give a try to cm launcher and lockscreen. They provide better lockscreen and more customizations.

[ solved ] Nova Launcher prime - double tap to sleep - how to?

as the title says - how to enable double tap to sleep (screen off) using gestures in Nova Launcher prime?
i know it has something to do with assigning an activity via Nova Launcher gestures, but i can't find any activity that relates to screen off or sleep...
any help is appreciated...
note:
i know how to do this using an extra app "Screen Off and Lock", but i just wanted to know is there a posibility to avoid any extra apps to achieve the same thing...
Download Turn Off Screen from play store and assign it to Double Tap on Nova launcher in Gesture Settings.

i think you posted this in the same time i was writing the "note" part in my post
I think not. If i remember, it worked well without 3rd party app, but now it is "disabled". Anyway, here is another guide:
"The Nova Launcher option
Another app that functions very similarly to the way you’d use Apex Launcher is*Nova Launcher. The same as you did for the first method, you will only be able to use this one if you also installed Greenify on the device. Therefore, you should go to the Google Play store and look for these two tools and install them.
Whenever you’re ready, check the steps below:
Open Nova Launcher and go to its Settings.Click on Gestures and Buttons and scroll down to Gestures.Select Double Tap and wait for the Choose Action menu to load.Go to Shortcuts, and then click on Hibernate and Lock Screen.
You may have noticed before that selecting the right settings in the first application is going to automatically send you to the second app you need to use. In this case,*Greenify will open*a new discussion and ask you to authorize Nova to use your screen.
You should go under the Automator and click on Allow Greenfy, and then confirm this option by pressing Activate. You’re now good to go and can test if the display is working properly by double tapping to send it to sleep."

thanks, but i don't use greenify and this guide is more complicated than "nova + screen off&lock" option which i already use...
Easy, you don't need to use a 3rd party app. Just doubletap the status bar to sleep
You can do this in every app, whenever you want to sleep just double tap status bar

i know that but it's not confortable enough...
i even had double tap navbar to sleep (g3twb) which worked well until i started using 5 buttons navbar making it harder to hit the blank area...
It looks like you may need first of all nova launcher prime, after that , you may need greenify as well.Here is what i did and it works.
1 . Go to Nova settings>gestures and input>double tap
2 . swipe right to the shortcuts tab and then go down you may find "hibernate + lockscreen"
3 . Assign it and it works!
double tap to sleep is working for me.
hope this helps.

1. i already have nova prime (else - i won't be asking because gestures don't work with free version anyway)
2. i've said that i got it working with "screen off & lock" app
cheers
Screen turns off if knocked on or close to status bar when I do it.
But what is the problem with having another app installed? Its size is ridiculous and it solves your problem, and always you can hide if u dont want to see it.

From the apps that I have Tasker and GravityBox can do screen off/sleep. And if you are using them already that doesn't count as an extra app, right?
Just realized this myself, one less app in my phone. I think I will go with tasker since I already run a lot of stuff with it.

Oh man, you should try tasker. It's what puts SMART in smartphone. Was messing around today with it. I found an old buss ticket that can work as nfc tag and put it on my phone holder on bicycle. I have set it to trigger launching Strava app, turning on GPS, setting brightness to max and forcing landscape mode for that app. And when I exit app, BAM, it reverts everything back the way it was. It's like slide and click instead of multiple actions. Might be overly excited about it right now, and definitely off topic here, but had to mention it hehe. I hope you will find a way to use that gesture the way you want, everything is possible on android

if you knew how i use my device you'd be asking "why don't i use nokia 3310 instead?"
no gps, no bluetooth, no location of any kind, no gaming, half of google services blocked etc...
no vibers, no hangouts, no skypes, no syncs - some calls, few sms messages... (i mostly communicate through google chat and emails while on pc since most of my work depends on beeing on pc anyway)
i read articles, browse and listen to music 90% of the time...
call me old fashioned - but i still love to have some "human manual control" over things on my device

Fingerprint Unlock not enough - OOS 3.0.2 requires pin when locked unconventionally

So I just upgraded to the OOS 3.0.2 MM build, and there's a new issue that's greatly annoying me. If you lock the phone with the power button, the fingerprint scanner will unlock it fine. However, if you lock it with something else (as I do with both shake-to-lock and Nova's lock actions), it will insist on ALSO asking for the pin/pattern unlock once your fingerprint has been scanned.
Anyone find a way to disable this security feature while still having a fingerprint unlock in place? Neither Gravity Box nor the security settings are presenting any obvious options
That's a feature of Android MM, not OOS. It can't be disabled.

There is no way to disable it? Even rooted? No xposed or system level hack?
It seems to be an error in design of Nova launcher and other solutions. They don't use the correct way of locking the phone hardlocking instead of softlocking, and therefore the phone will ask for pin just as if you restarted your phone.

I had same issue when i used double tap to sleep in nova launcher prime.... i is because it uses device administrator to lock phone! I fixed by using root to lock my mobile....
Long story short you need your application to use root to lock your device!
But what if the shakelock app I use (and love!) doesn't use root....? It's sounding like I'm out of luck here. How have you managed to make Nova use root to lock?
I guess I'm more of an Apex guy, don't fancy Nova launcher even though I bought it a couple of years ago. I just double tap on top part of screen to lock, or press the power button, or let it timeout. For unlocking, I just use fingerprint, no fuss, no asking for code.
I was happy with Nova Launcher (which is currently on sale for $0.99 on the Play store), until I found out that it has a bug in voice searches from the Home Screen's search bar. It annoyed the heck out of me as it kept on complaining "App not installed" when clicking on the little mic. I had to click on the search bar and THEN click on the other mic that appeared, inorder to access voice search. Defeats the purpose of the voice search b/c I use it a lot while driving and I cant be bothered to be clicking through so many hoops. So I switched my homescreen launcher to Google Now Launcher, while keeping everything else Nova Prime.
For anyone interested, I have found a sort-of solution. Using a combo of Xposed Maxlock and Lockscreen Disabler, it's possible to have a lockscreen up that you can dismiss by using the fingerprint sensor. There's a fairly obvious downside in that it doesn't matter what fingerprint hits the sensor, as anything at all unlocks the screen (which is Lockscreen Disabler's function) but it works as a way to use a non-root lock method that still allows you to unlock the screen with just a touch. Until such a time as someone finds a better solution
I'm pretty sure that it's easy to write a simple apk that uses the root method to call the screen off function. Only if someone would write that
Why I tell that - because if You double tap the status bar - the screen locks and You can easily unlock it just with the fingerprint sensor... therefore, that function does exist already in the ROM.
Yeah, I've got the Nova rooted lock function working, so those actions or GravtiyBox stuff like double tap status bar will work and not require pin+fingerprint, but my specific ask is this way to lock the screen by quickly flicking/shaking the phone (which is GREAT and I don't understand what hasn't been included in stock) - none of those seem to use root to lock so this workaround is a way to have that convenient screen off + convenient fingerprint on.

Thanks for the reply, but actually the problem is not unlocking the phone, because i remember the pin, the main problem is why my Zenfone 3 seems like not detect my fingerprint scanner, you can see the screenshot, there should be a fingerprint menu, but now its gone. how is that possible and how do i fix it? its so annoying because fingerprint is the major feature which makes it a bit expensive.

I seriously don't know. If i were in that situation. I would backup all my data first. Then reset the phone to factory state. If it happens again. I would contact Asus. Or check their forums for a solution.

You use ZenUI Launcher ?

Probably due to root access, mine is unrooted so fingerprint won't work with Nova. Installing dan configuring Screen Lock Pro will fix this, but have to wait 10 seconds after screen off to allow fingerprint unlock. Not so convinient.

Exactly, the convenience it brings is really great. Especially if you have a 25 character password lol. My password's too long for me to enter it all the time. And yes, maybe because of root access i'm able to do that

Have you ran Asus hardware test?
If not - have a try:
- open phone calculator (stock Asus) and type .12345+=
Pls note - no zero before the dot
- in the pop-up app, select single test, then fingerprint test.
If the test result is ok, your issue is software only. In contrary, it's a hardware failure.

Great tip.
I ran the test, fingerprint test went wrong.
So, in my case, it`s a hardware failure.
I have the same problem with ze522KL. Initially finger print worked for a few months. suddenly it stopped working. What. to do?

Just make sure it isn't hardware failure by running above mentioned hardware test. If the test suggests there is nothing wrong with hardware, then switch to swipe as unlock method first before setting up and returning to fingerprint unlock from scratch.
Mine is having problem like this.
Hardware test says it is working well but when I tried to register print no response at all.
Tried the pattern lock method as well but no luck.
Same case
It's happened to me also. I have done the test (.12345+= in calculator) and it said "something wrong with fingerprint test". For this case i'll contact Asus. It's really weird why so many people having same problem like this. Actually my device has been used for only no more than 3 months. I'm afraid there will be new other problem in the future.

Need Help with swipe screen

Hi everyone, I just got my AT&T Lg v20, for some reason I can't seem to get rid of the "swipe to unlock" screen. It is really annoying because I set up the fingerprint unlock and I thought that just with the fingerprint it can be unlock, but after I unlock it another screen shows up (the swipe to unlock screen) and it is very annoying. Does somebody knows what is going on?
It seems if you use a third party launcher, the use finger print to unlock will still require the pattern when you use knock to close the screen.
Either use the stock launcher , or in my case, greenify.
double tap in Nova to start Greenify's auto force close for apps. check the alternative method in Greenify settings for this to work
Sir you have saved my life. Thank you. I had the buzz launcher but it was not enabled I just unistalled it and it worked thanks again.

[GUIDE] Enable DT2S without entering in conflict with fingerprint unlock [NO ROOT]

How to enable DT2S without entering in conflict with fingerprint unlock​
Hi guys, i recently found a way to enable the DT2S (Double Tap To Sleep) feature on our Honor 8 without giving any administrator permission. As you probably know, when using any application for DT2W it requires the "Device Administrator" permission to immediately lock the screen, but apart the fact that this option could be potentially dangerous, giving administrator permission enables a security measure wich consists in PIN immission right after the screen has been locked (and you try to unlock it with fingerprint). But this method seems to work flawlessy, avoiding the nuisance to insert a PIN everytime the device gets unlocked. The process is quite easy and can be achieved without root, but there are some requirements that i'm going to list below:
You must use Nova Launcher Prime as home screen replacement
You must to be on Android Marshmallow 6.0 or Higher
​
1. Open the Nova Settings and select the "Gestures" option
1. Take a look at the arrow in the first attachment
2. Select the "Double Tap" option when shows up
2. Take a look at the arrow in the second attachment
3. Select the "Shortcut" tab on the right
3. Take a look at the arrow in the third attachment
4. Select the "Lock screen" option
4. Take a look at the arrow in the fourth attachment​
By following the steps above you'll be able to take advantage of the DT2S lock method without compromise the fingerprint unlock function. BTW i don't know if this is a functionality or a bug (i don't think it's a bug), the only thing i know is that it's working good with no problems, also after reboot and shutdown.​
PAY ATTENTION
I'm actually using the BETA 5.5 version of Nova, not tested with regular version​
Hope this post could help someone Enjoy!​

I didn't understand if the P.S line was sarcasm or not. However if you knew that, good, but not everyone knows that. If you just go in Gestures/Double tap/Nova/Lock screen it doesn't work because ask for admin permission, but if you go in Gestures/Double tap/Shortcuts/Lock screen that works. I just wrote this to help someone who didn't already figured this out
