Sometimes I have to knock knock twice in a row to turn on the device. It works well turning off, but on half of the times it won't turn on. Gotta do it twice. Anyone else encounter this?

I do not have that issue, but I have read in a few posts that it can be dependent on where you are knocking on the screen.

I think the biggest issue is knock speed.... mine works damn near 100% when I slowed down some, and knock slower like it showes at the end of the G2 commercials....
I think it's partially related to the proximity sensor. There are times when I can't get the knock on to work at all and when I hit the power button the screen shuts right back off.
Usually a few swipes over the sensor makes it work again. Sometimes I'll go in and turn the Knock On gesture off and back on and then it seems to work great for a while too.

This is my exact problem. The phone just decides it doesn't want to wake up with knock-on...but after I press the power button, it only turns on for half a second and it's out again. I never tried swiping over the sensor, but hopefully it works because it's mighty annoying when it does it during a call!
I wonder if there's a fix for this?

this, if you are trying to do it like you did on the nokia n9 or nokia 8800 then it won't work
slow deliberate knocks are the only way
waiting on the g2 to arrive, but on my review unit, knock knock wouldn't respond correctly if i left the phone on the table, but if i picked it up, it would work nothing scientific here just an experience of one person and one prototype
I had the same issue... What fixed it is: 1. I found that the screen protector was hindering it somewhat. 2. Go to settings->display->screen-off effect-> and change it to simple. This REALLY seemed to help. Let us know!

I did notice it does seem to behave better when set to simple for the screen off animation.
My screen protector does have a cutout around the sensors. Keeping the sensor area clean enough to qualify as having OCD does seem to make it work properly the first time, every time. Maybe it's overly sensitive?
Edit: Scratch that. 30 seconds later it's behaving erratically again. Maybe it's not the fact that it's clean, but the swiping over the sensor that temporarily resolves it.
it also seems to work much better when knocking at the top of the screen where the statusbar would be.
So I ended up swapping the phone out over the weekend for a new one and now everything seems to work just fine. Seems to indicate that it's not a software problem, but rather a hardware issue with the proximity sensor.
Guys if your covering the sensors when turing the device screen on it will turn right back of on you. It's a feature LG implemented so the device wouldnt wake up in your pockets. Don't cover the sensors.
Need a little example? Grab your phone and cover the sensors and knock knock knock.You can knock till the cows come home but it will not turn on. Same thing goes for the power button but its a little delayed and will turn the screen on for half a sec and turn right back off. Practice not to do this because your phone isn't broken. There is actually a thread on this deep in the forums somewhere but its been forgotten now.

This is true however there are indications of problems with the proximity sensor as well. Some of the devices are behaving as if tree sensor is covered even when it's not.

Thanks for this.. Very insightful.. I tried it immediately LOL
I had the same issue. I have no case or screen protector on, and was not covering the sensor when trying to wake the phone. For some reason though, knocking wouldn't wake the phone, and pressing the power button would only turn the screen on for a few seconds. I want even given enough time to get past the unlock screen. I went into the store and they are sending me a replacement that should come in later this week. It doesn't happen all the time. It is much more noticeable after receiving a call though.

Definitely is dependent on the proximity sensor. If i just have my thumb on the edge of the phone by the sensor it will display this problem. Even with my finger a half to one inch above it will do this. I will be paying close attention to the proximity sensor from now on when it doesn't work. Still have a few days to return and thought i had an issue but maybe not.

sometimes its also greasy fingers, at least in my case, rarely though
As long as you tap twice the same place it's working fine. If distance between first and second tap is greater than 1 - 1.5 cm it won't work.
Got the same problem on my d802...when i left the phone on my table for 2-3min it wont wake up on first knock knock even power key wake it up for 1sec after auto turn off again....even with no screen protector....i noticed that sometimes there is a delay about 5-10sec after knock knock and screen turns on....other thing i noticed when i knock on immediently after turning off it works 100%....BUT i also noticed when i knock on after a while it turns on and i can unlock got vibration and sound of the unlock but i cant see anything. Screen looks like its off but when i look closely i can hardly see widgets and when i set effect to tv out i can see the effect by pressing the power button...when i press the power button again screen turns on like normal...i noticed sometimes on a rerboot the lg bootlogo disapears the led is working an showing all colors but the boot animation is gone like the screen is off at the bootup...dont know why after the bootup the pin lock screen is showing up normal....sorry for my english^^
Hey, guys. I'm a huge fan of this phone.. I can't get over what a good value it is for the money. I have almost zero issues with it. The one issue I do have is the inconsistency with tap to wake. It seems like after it has been in my pocket for a while, it just fails to work. This happens periodically throughout the day, to the point where I just can't rely on it. It drives me mad because that's kind of a must have feature for me. To be fair, the only device I have never had tap to wake issues with is LG phones. They just seem to work all the time.
I did raise the sensitivity following the guide found on these forums. It's something else, like the pocket protection is stuck on or something. Anyone else experience something similar? I don't want to use the fingerprint reader. Is there something I don't know? Some setting I'm not seeing? Or is this just how it is?
Still a great phone otherwise. I wish I could fix this one little thing.
Is your screen clean or dirty? Have you tried wiping it down with 70% isopropyl alcohol and seeing if that improves the responsiveness. Is the phone hot when it's not responding? Are your fingers dirty?
It's not very sensitive, you definitely need to give it a couple of thumps unlike the taps on an LG phone.
There's a learning curve with this phone. I nearly dislocated my shoulder trying to shake the flashlight awake before I realized you had to wake the screen first

I mean, this only happens when I take it out of my pocket. Tap to wake works fine the rest of the time and my screen is definitely clean.

I'm coming from an lg phone as well, I have found the taps must be slower. The pause between taps needs to be just a little longer and it works for me almost every time.
Double tap to wake doesn't work when the phone has gone into doze mode. ZTE knows about this issue and is working on a fix.

Doze seems to break a lot, including notifications on other phones.

The doze should not kick in if the phone is moving. One of the conditions is that phone should be static for a while. More likely it's something based on proximity sensor to prevent accidental turn ons. I found that i would have to tap several times to wake it up most time i have to do it twice. The force touch is buggy

Well, I haven't had any issues since I disabled doze and I doubt that's a coincidence.
I agree that doze shouldn't kick on in your pocket, which is why I originally suspected the proximity sensor, but it could be a bug in ZTE's ROM.
My Mate 8 had a malfunctioning doze mode that would cause all notifications to stop as soon as the screen went off, even if the phone was moving. I fixed that by disabling doze also.

The same issue I'm having on both colors I'm having .
Most of the time when picking the device from my jeans pocket refuses to open with double tap even after several attempts.
I have to unlock by pressing with power button and then when holding my phone it stating to work fine.
It's really annoying and frustrating.
Only double tap to sleep with nova prime or 3D next launcher working 100% perfect in all situations from home screen.
Also I'm using glimpse notification and enable the option to double tap to sleep from lock screen and works perfect all time.
Another feature having is it wakes up the screen automatically every time having notification alert and after screen being off continuous the led to be on as a reminder.

So, I was wrong. Disabling doze didn't fix it. I went back to my OnePlus 3 for a day to get perspective. That phone pretty much never misses a tap-to-wake. It just works. Conversely, the Axon regularly "goes to sleep" when it's in my pocket and I can tap on the screen as many times as I want and it will never come on until I hit the power button. It's definitely not working like it should, at least not for me.
I'm not sure how anyone can say that it's working fine. I like everything else about the phone. This is just annoying because I can't rely on using tap-to-wake. I spend more time tapping on the screen when it's not working than I would if it just didn't have the feature and I had to use other methods. If ZTE could fix this to work as reliably as an LG or the OnePlus 3, I'd be in heaven.

Hope ZTE makes improvements on that very useful feature to become just like LG.

I'm hoping to get double tap to wake function working so that I don't have to pick up the phone when it's resting on a surface.
Anyone have double tap to wake feature working on their Pro 3?
Which Xposed module are you using?
Thanks.
Not Xposed module but this one works for me. Just a hiccup when combined with FP unlock.

Interesting, I always thought DT2W needed kernel support. Have you had any false wakes in your pocket? That was always what killed it for me on phones that didn't have it stock. They would randomly wake up in my pocket (not using light sensor clearly)

That's not a real double tap to wake. The app just runs an all black wall paper as 'off'. Since the Le pro 3 has an lcd rather than AMOLED screen, it would have a huge impact on battery life.

Well as far as my eyes can see, it does wake and shut of screen. Try it first before making any wild guess.
--------------
I stand corrected, yes it does turn the screen blank only as soon as you turn of the screen via power button or the nifty (hold back) button.
So if you are not gonna use it like overnight doze or in your pocket, turn off the screen twice to make sure it is really turned off.
Maybe with Android 9?

Reading the Elemental X thread, it seems like it won't happen without a big battery drain.
I have it working use Nova. Elemental. Double tap sleep and wake.
You an enable lift to wake as weel.
I found a generic double tap to sleep. Install this app, Pixel launcher mods. It allows one one to use system ui tuner, add a double tap to sleep widget zone, where the double tap puts it to sleep, and allows u to use the existing launcher with icon packs. The app is by quinns mighty apps and on xda labs
Oops, one failed, here it is.

I can get Nova to perform double tap to sleep. But there is nowhere I can find that Nova can be customized to do double tap to wake.
EX Kernel allows for sweep to sleep but again no sweep to wake or double tap to wake.
It's not as big of a deal on the Essential Phone given that the fingerprint sensor on the back effectively serves as a 'tap-to-wake' sensor. Just put your finger on it and it wakes up the screen and logs you in.
Double tap to wake requires power to the touch screen. This would require the screen to receive power which means it would be on. This makes sense on an LED screen since pure black on an LED screen means the pixels are off. On an LCD screen such as this phone has, you'd have a glowing, illuminated, black screen and battery drain since the display would have power going to all of the pixels.

Yeah good point, I had that thought too briefly, till I realized LG has been doing it for YEARS and still does it this day (I think) on MOSTLY its LCD flagships. I think my V30 was POLED, but outside of that all of the other ones were LCDs. Wondering how they did it...

that's not true only the digitizer needs power not the screen
the screen is actually 3 parts
the lcd/led
the digitizer
and the top glass

like I said above the type of screen makes no difference it's the digitizer that detects the touch
I noticed if one enables Double Tap to Wake feature, the lock screen wakes in one's pocket without double-tapping it. It appears if the screen is too sensitive to touch and wakes up as if one were double tapping it.
I normally carry my phone in my shirt pocket with the screen facing inwards and have noticed this happens often when walking or standing up that the screen wakens with double tap feature on.
I have now disabled this useful feature to save battery.
Please check if this is happening to you as well and post your replies.

I also noticed that, but if I turn off the wake when you lift it feature the screen does not come on. Dbl tap works fine then.
Also def make sure that accidental touch protection is on

The only time it does not do this is if I place phone in my pocket with screen facing outwards. Annoying as I prefer screen to face inward for better protection.
