In the Motion Gestures, it says that this phone can double tap to wake and to sleep. Double tap to wake is working great, but it doesn't double tap to sleep. Has anyone else noticed if double tap to sleep works?

It works, but only in the lockscreen.
Sometimes double tap doesn't work for no reason, do you have any idea what's going on?
You can also go to Dev settings and tick the double tap status bar to sleep. Much handier than the lock screen bc you have to turn the phone OFF to get to lock screen and defeats the whole purpose of double tap to sleep...

I know about that part, but even when I hold it correctly it doesn't work, it only works again after I reboot the phone

If you just got your phone, it may have been sitting in the box awhile and may need to be updated. Go to the Play Store and search for HTC Motion Launch to see if an update is available. Also, check on your phone and/or with your carrier to find out if a software update is available for your phone.
Hi everyone,
I have an LG G4 H815 model, upgraded to Marshmallow six months ago. Last month, the device started to have a boring problem with the KnockON function. Basically I can't wake up the display while the device is locked: the double tap is not working properly, it works every 6-7 times I try the double tap. Neither the Glance View is working, and when I try to do it, rarely It unlocks the screen: seems that the device in that case sees the Glance View gesture as a double tap.
I've already tried everything: hard reset, downgrade to Lollipop, another hard reset, proximity sensor test with multiple app. Everything works fine, also the double tap to lock, the touchscreen works perfectly. The only problem is the KnockON and Glance View while the G4 is locked. I don't have any kind of case and screen protector.
Any ideas about how can I solve this?
identical issue

i have the same issue,some solve ?
Well another victim suffering from the same problem here. Really getting sick of this device man.
I've tried with the Always On app from the Play Store, which allows to double tap to unlock. And it works perfectly with this application. Now I'm sure that we're talking about a software problem

That is the feature of the application if you look carefully at the details on its google play page. When you use the app, your display will always be on. It is not related to the original double tap to wake already which is supposed to work when the screen is off. So I would assume it's still a hardware problem. Goshhh why are there so many hardware problems with LG?

You're right...Didn't assume that problem.
Hardware issue
I may be wrong, but I feel that this may be a screen/connector issue. I have two G4s, one has the KnockON issue described in this thread, and the other one doesn't have the issue. I recently had to put the mainboard of the G4 with functioning KnockON into the chassis of the G4 with the malfunctioning KnockON. When I did the switch, KnockON was problematic even though it it worked perfectly when in the other chassis. I switched the boards again to make sure I didn't break something, and sure enough, KnockON was working as it should when the mainboard was put back into it's original chassis. KnockON even worked with the mainboard from the problematic phone, when it was put into the other chassis which didn't have KnockON problems.
This leads me to thinking that there's a problem with either the screen or the mainboard connector. I could be wrong though...

I know there is a little rubber plug in the prox sensor a lot of people forget to put in theyre new lcds. And it causes knockon not to work very good
Hello,
I had the same problem as well, it seems that I loose the setting from time to time...
I found the solution already in the forum but cannot find it again.
Here it is :
1) Install quickshortcutmaker from the playstore
2) select "normal search"
3) search for "knock on"
4) launch the setting with the "try" option
5) see if the box for knock on is ticked (if not tick)
that's it, I hope it helps
The screen protector.
Make sure its nt envolving the proximity sensor
I've already tried with the shortcut app, but it wasn't useful because KnonON was ticked. I don't have the screen protector, so I suppose that the problem is related to the screen or the proximity sensor itself. Today i'm gonna open the phone and check if there is something wrong, or maybe I'll take it back to the customer service at the shop
It doesn´t matter what you tried, I talked to an LG tech lately, it´s a hardware issue. The proximity sensor is partly defective, so all these software workarounds don´t work. Period.
Missing option

Since I have problems that I cannot manage to solve with the KNOCK ON function (sometimes it doesn't work while most of the time a simple slide is enough to wake up the screen, turning it on while in my pocket) I wanted to turn it off with the quickshortcutmaker app, but it seems like I simply do not have the knock on setting. If I search "knock on" it gives me no results, while typing "knock" only the knock code wizard is found. I have done a factory reset last week, but I still have the same problem.
How is it possible that I cannot find the Knock On option even though I can still turn on the phone with the double tap? Anyone had the same issue?
I have the opposite problem. Mine is too sensitive; when I tap once and then again a few minutes later, this is registered as double tap! This means that the screen turns on itself in my pocket all the time. If I blow on it, it can turn on!
I'm not using a screen protector and the screen is clean. I think this started after I left the phone in the sun for a long time while hiking. The proximity sensor, light sensor and touch are fine.
I have not found a fix so just disabled KnockOn as @marcge 63 suggested.

Hi im having this problem too LG G4 F500L on stock nougat suddenly this double tap to wake and glance view bug appeared i tried everything i think this is hardware problem

Same here. Then i disable knockon function.

Same problem h815
Phone calls(whatsapp call) working perfectly.And screen turning off Itself,proximity sensor working but double tab unlock Or knockCode not working properly.this is lcd screen problem or Kernel Problem? Now im using imperium rom.sometimes screen opening itself And i try 1-2-3-~ tap and opening 5 -10 second later.this is a NEW PROBLEM
Wow so many in here with this bug i hate this double tap to wake not working im trying to downgrade to lollipop to see if the problem will go away but too bad nougat have an anti rollback i guess i will use my power button now lol
So i came back to where i bought this phone they say my sensor are malfunctioning and need to be replaced so i guess its really a hardware problem
I've seen lots of people complaining that Mi A1 does not have "tap to wake" feature. I personally don't miss it since i'm using the fingerprint reader to wake and unlock in one go.
However, I've seen and tested that small free and open source app: https://play.google.com/store/apps/details?id=com.jarsilio.android.waveup
With this, you can wake phone by "waving" your hand above the proximity sensor.
I've put it on my A1 for 1,5 day now, and have seen no battery drain Developer explains:
Unfortunately, some smartphones let the CPU on while listening to the proximity sensor. This is called a wake lock and causes considerable battery drain. This isn't my fault and I cannot do anything to change this. Other phones will "go to sleep" when the screen is turned off while still listening to the proximity sensor. In this case, the battery drain is practically zero.

But it seems on A1 we are good to go.
I know it's not exact same feature than "tap to wake", but you might still want to give it a try if you're looking for a way to wake phone without using hardware button. As well it can wake the phone when taken out of pocket!

Thank you very nice. Working nice so far and no high battery usage

First of all, thank you for the recommendation. This app is working flawlessly for now but I'm just curious about a feature. I have enabled the feature that allows to cover the proximity sensor to lock the screen. It needed device admin permission for that. Now, when I wave to wake it up, it takes me to the enter pin screen instead of fully unlocking so I have to enter the pin to unlock the device because it says that the device is locked by admin. Is there a workaround to bypass this one extra step?

This looks like the Nova's "double tap to lock" feature. If you're not rooted you need to grant admin permission to lock the screen, which requires PIN everytime you log back in.
Exactly, if you're not root, the "lock" feature is no good if you use fingerprint, I have disabled it, anyway phone goes to sleep on its own.
You should also check out KinScreen (https://play.google.com/store/apps/details?id=com.teqtic.kinscreen), it does wave to wake and also has many options to control when the screen stays on. For example, you can set it to stay on when your phone is at more than a 45° angle (like most times you're on your phone, reading something).

You can basically use double tap to wake with this, just enable it and tap your proximity sensor to wake.
This has been bugging the ISH out of me....
On my OP6.. if i was on a call and i touched my FP sensor it unlocks the phone for me to access anything i want.
When on my P3XL doing the same doesn't produce the same results at all, i have to bring down notification window press settings and then it asks for FP.
I also have my navbar hidden, which can be affecting how this entire thing functions too, not sure.
Has someone figured out a way around this?
I just called my phone from my work number and the fingerprint sensor unlocked. Phone was locked when I called it, I called my phone, swiped up to answer. While in the call I tapped the home button and was taken to the lock screen. Touching fingerprint sensor brought me to home screen. With the screen off, touching fingerprint sensor also unlocked and brought me to the home screen.

well that's because you still have your home button..
I suppose this is more relative to those using gestures and hid their navbar...
I also did it with screen off, as I said, and it worked both ways.

Try shutting the screen off first. I just tried again and with phone locked got a call and pressed sensor with screen on and nothing happened. Tap power first then touch sensor and it should unlock. I don't have gesture nav so I can't rest that part.

What gesture app are you using. Some will pause themselves when the phone is locked. When you answer the phone while it's locked the app may have paused it's self so it's not really running. That's why your swipe up to go home is not working

Following these steps to resolve fingerprint unlock issue after Android 10 update:
1. Delete all existing fingerprints.
2. Turn off 'Always On' from Display Settings
2. Set Screen Lock(Security Settings) to 'None'
3. Set Battery Optimisation to 'Don't optimise' for 'In-Display Fingerprint' app.
4. Force stop 'In-Display Fingerprint' app, and remove cache and data for this app.
5. Restart your phone.
6. Select Fingerprint option from Security menu and add your fingerprint, make sure raise to wake up toggle is set to ON in fingerprint menu.
That's it.
If fingerprint icon does not appear on raising the phone, tap the screen twice for it appear.
P.S. : You will have to follow these steps again if you restart the phone after all the steps.
After all this Fingerprint still breaks after,
1. Clicking Notification from lock screen
2. Picking up call from lock screen
Maybe step 3 and 4 are not necessary, But still added it to be safe.

It stopped working again..
Worked for a few minutes and stopped...

i received only the february update without android 10 and i have same problem so its not from android 10

Yeah bro
Anyone identified root cause of for fod disappearing in lock screen?
I identified few scenarios which are breaking fingerprint scanner on lock screen.
1.double press power button, while jump to camera is enabled on double press power button
2. Unlocking phone with any other unlocking methods like face recognition and pattern.
Please share your experience
Having absolutely zero issues here all works as normal and always has since the update.
What I did to get android 10 was completely flash the last stock android 9 using miflash.
Setup as normal and signed into all my accounts. Setup fingerprint and lock screen pattern.
Updated to android 10 through prompt.
Booted to a fully working os and then proceeded to unlock the bootloader and flash magisk patched boot.img through fastboot.
Been working perfectly ever since. No issues with fingerprint icon not being displayed or fod not working or any issues as a matter of fact.
Noticed a slight increase in battery for the first couple of days but that soon turned into a 10 hour average sot since so no issues there either.
I would urge anyone who has issues to take logs of every bug you find and send it to the xiaomi Dev team through the 'feedback app'.
I think they have most bugs sorted now but no harm in sending they might find other issues
I couldn't post it that's why posting it here.
Whenever I connect headphones to mobile and call anybody, it works fine. But if call and then connect the headphones, other person can't hear me at all. This has started after I updated to android 10. Anybody has same issues?
Thats wired headphones
