[Q] Knock ON Latency - G3 Q&A, Help & Troubleshooting

Hey guys, I love knock on but it doesn't always respond. Sometimes I have to try once or twice to get it to wake.
FYI, D850 here, rooted-stock with screen protector and case. I've tried this with phone stock, no screen protector and no case. Same thing happens. I've factory reset, hard-reset etc... and it still happens.
I'm no expert but it feels like the phone goes into a deep deep sleep and takes a couple of tries to get it going.
Is that normal? What's been your experiences?

I have a D855P (Brazilian version), and the Knock On works like a charm, but you have to double tap the screen in the correct time, not too fast. The Knock Code is a little more unresponsive, sometimes it doesn't work perfectly, but is a very good feature.

Exactly. It's just like a mouse. Don't double tap correctly and it won't work. Also if you aren't holding the phone firmly in your hand it senses other movement I think and screws up the double tap.

Your username describes this situation perfectly. :laugh:

Hahaha

I think he's right. I've got my g2 a few days ago and I have noticed the same. KnockON ALWAYS works when I want to turn OFF the screen, but when I want to switch it on, it's annoying that I must try couple of times before I can use the phone. Is there any way to make phone always react to knocking?

Phone dialing while in pocket, unsure what to do :/

Hey i have a quite a bad problem. My phone appears to be unlocking its self very easy and ringing people in my pocket, today it rang 8 people in the space of an hour. Ive got pocketshield but this stops it picking up calls, not ringing them. Im unsure what to do. I dont even know how its happening, im thinking the top button must keep getting pushed in my pocket or something.
Any ideas/apps to lock phone after wakeup? I dont want to put the pin on it because it may end up locking my phone instead! plus its a bind having to enter a pin every few minutes. Something like pocket shields scroll down the screen etc would be good. But i see no option to enable it for when waking up.
Thanks.
I've had no such issues since using S2U2. Give it a try!
Or LockMeLite - much lighter than S2U2 and doing just what you want - locking the screen and hardware buttons when power button is pressed and unlocking the screen on incoming call so you don't have to unlock to answer and still keeping the buttons disabled so you can take it out of the pouch without accidentaly answering/ignoring the call.
Me too.. LockMeLite has been definitive for me. No more "lost" calls by hardware.
Fk
My solution was to stick a crystal case on it,it recess's the power button so its not pushed by accident.
if u press and hold the phone icon bottom right it locks the screen , to unlock pull out the stylus.
the problem is its not to do with calls or texts, i have pocketshield for that. Its to do with the powerbutton keep getting knocked. At least i think it is.
holdign down the phone key to lock the screen sounds like a gd idea ill look into that.
And yeah getting a protective case might solve it too. Ill cehck that out too thanks, though i do kinda like the sleak design. I gues its gona get ruined proably lol.
:EDIT:
Simply locking the screen before turning it off works a charm! thanks. Now im just wondering, is there an app that will just auto lock it when i turn screeen off ? Just makes it all that easyer so i dont forget and call people again!
I had the same problem before using a belt case. I tried s2u2, but it's lagging. Now I'm satisfied with Pocketshield. Just work in its setting and you can have it work well.

Again - LockMeLight. It locks the screen automatically when the phone goes to sleep and you have to slide the screen down when waking it to unlock it. On top of that it disables the hardware buttons when locked, so no accidental calls are made when you unwillingly wake the device even with the screen locked.
original case
i use original htc case for hd.

Lockscreen Motion Gestures: Not Always Registering?

Just received my HTC One M8 and noticed when the screen is off and I double tap or slide up to awaken the display it doesn't always respond. Anyone else finding this problem? It works maybe 80% of the time.
Alright, so an update: Seems you have to be holding the phone in your hand to do the double-tap to awaken. You an do it while it's on the table beside you, but it doesn't work every time. When hold it, it seems to recognize the tap. Wish it was more like NOKIA's glance feature, but hey it works.

It's orientation based so make sure your holding the phone correct before doing the gesture.

So I suppose my phone has the most weird hardware problem ever.

Please don't move my thread to Q&A as I already made a thread there but no one replied.
So what happens is that a touch is randomly registered on the screen of my phone sometimes when I press the power button. This isn't an HTC lockscreen specific bug as I have established it happens with PowerAmp lockscreen as well. I have done a full factory reset and it is still happening.
I don't use lockscreen security so the obvious problem with this is that so many times upon pressing the power button a notification is clicked and immediately opened as a result. This problem can be avoided by using double tap to wake but it's far too easy to activate by mistake so I can't stand it.
Repeatedly pressing the power button will not reproduce this result, it seems to only happen when the power button had not been pressed for a few minutes. But this cannot be a bug related to sleep mode since this happens when playing music as well.
So what I would really like to know is if there is anyone else with this problem? My M9 had been so perfect all this time but this has just ruined the experience. I don't exactly remember when this problem started but I do know it wasn't there from day one.

Seems like a hardware problem. Something presses your digitizer (touch screen).
If u have any screen protector , remove it.
If not, take it to warranty.
Good luck!

HTC doesn't provide warranty in my country so I am outta luck. I don't have a screen protector so I guess I am screwed.
I guess I won't be buying HTC again. I already tolerated the crack on my bezel but it seems every HTC phone has some hardware issues. It's too bad though because I loved HTC software and performance, the M9 had been nothing short of a spectacular phone for me.
It happened to me too when I used a stupid Samsung charger. Try another charger, I don't know why but sometimes the current of power is somehow overflowing the chassis of the phone that the digitizer thinks the difference is actually a touch on the screen.
I want to update this thread. As it turns out it's 100% a software issue. How I figured this out is that when I turn on "double tap to wake" this problem completely disappears even if I still use the power button for unlocking. So basically the bug comes into play when you turn off double tap to wake as it is turned on by default.
So is anyone not using double tap to wake? Are you experiencing this problem? Unfortunately I find double tap to wake extremely annoying as it is so easy to wake up the screen.

That's quite a unique software issue then. At the risk of sounding like an obnoxious tech support guy, I would absolutely backup everything and then just factory reset (or wipe and reflash your custom ROM) when you get the chance and quickly check if the problem is still there.
I've been using double-tap and it has actually been the opposite for me - I find it annoying how hard it is to wake up the screen because you need to hold up the phone vertically before double-tapping, rather than just tapping while it's lying on the table or in your pocket.

I have already done a factory reset to no avail.
That's strange because I can activate double tap to wake from any orientation.

Oh my bad re-read OP and saw you already mentioned it.
Hunh, I stand corrected I guess, since now I'm able to wake from having it flat on the desk. Could have sworn that didn't use to work. But still, I'm not by any means accidentally waking it (if I pick my phone up, it pretty much means I want to use it).
I can't replicate the digitizer anomaly, so not much else I can say other than good luck. Have you tried custom ROMs?

It might take a day or 2 of usage to replicate the problem, it doesn't happen most of the time.
I wake up my screen accidently sometimes when putting it into my pocket after locking it which is hugely annoying as the lockscreen is kinda easy to unlock once it's woken up.
I really can't be bothered with custom ROM as I am done with all of that. I'll just live with double tap to wake.

That's the design. When lying flat, you can wake the phone with a triple-tap.

Double tap to wake consistency testing

Dear All;
As you might already know, double tap to wake function not very consistent(ofc better than previous ones but sometimes it stops working completely until you switch it on with power button).
I was trying to find what causes this and I might have found it. I can reproduce this problem every time with my phone but I need to know if your phones has the similar issue or not.
So... it is very simple, just power off your screen(not shut down) and rub your phone screen(like cleaning) with a thin cloth using your palm(or bare handed) for a time. Mostly fast 10 circular motion rubs would be enough but try a bit longer if it does not. Trick is to use all your palm not just fingers(covering your screen).
Then try to double tap to wake your phone.
Please let me know the results, I think digitizer is overflowing with inputs so disabling the function temporarily.
YES!! It most certainly does happen (after giving the screen a nice rub). After that it just doesn't want to work again until I manually turn it on.
Also, it works everytime without fail while charging. Maybe it has something to do with power management? It's also disabled in battery saver mode.
(Rooted Pixel XL with Elemental-X 1.08)
Possibly intentional?
imagine unlocking your phone and putting it in your pocket with the screen facing your leg. You know how it will take the heat from your leg and register touches? maybe this is a combatant against that.
if double tap always worked i could see my phone constantly waking up in my pocket ( like my old g2 and g3 ) and wasting battery.
try this. place the phone flat, give it a good rub, and double tap, if it dont work, stand the phone up and then try.

Power Button worn out? Accidentally starting Camera despite clicking it only once.

EDIT: Fixed it (for now). Copied from my post on site 2.
What's up guys, I'm sorry for the late followup. It turned out, that I was too lazy to send it back. Now, almost a year later, I'd gotten into fixing phones and got the courage to open up the device and see what's up with the power button. It felt like the issue has been a bit less noticeable recently but I checked the replacement parts prices and how to open our phone up.
I think I've fixed the issue by adding one layer of electrical tape over the button-contact. I believe the issue is that the pin a just a little bit too short to reliably properly click the button.
Short tutorial:
Turn the device off and remove the simcard bracket.
It's actually super easy and you don't need to screw or remove anything. Google "Xiaomi MI A2 LITE disassembly screen battery smontaggio" you'll find a video, in the beginning the guy shows how to remove the backcover. I've used a hard, plectrom-looking "opening-pick" at the bottom, then carefully but firmly around the sites. You don't even need to remove the flex cable from the back, just make sure you don't rip it off. Cut off a short bit from the electrical tape, tape it from the battery to the contact, so it doesn't fall off. Close the case again, turn it on and check whether the powerbutton still clicks (doesn't stick) and test the screen lock. Post back if this has worked or if you've tried it.

Does anybody have a similar issue?
I've ordered the device from gearbest to Europe. Everything worked nicely.
However, recently when I hit the power button it sometimes triggers the double click interaction and opens my camera. I've tested a few ways to press it slightly from the side, with more force or less. However it will 1/3 times vibrate and start the camera like I had double clicked it, it's more likely when I hit it a bit too lightly though. Could it already be worn out after 2 months? This never happened when the device was new as far as I ran remember.
Yes I'm aware that I could change the camera shortcut but this doesn't stop me from worrying about whether my powerbutton will give out soon.
I was using the phone happily in the case Xiaomi has provided. Dropped the phone once and got a little scratch on the VOL Button but other than that, nothing crazy has happened. Does anyone have a clue whether they will still replace it? I'd gotten it in mid-August.
<message deleted>
Buttons are usually the main gate to "planned obsolescence". I bought this device after my nexus 5 power button started working funny (I physically removed it and worked only with gestures). So, now I try not to press the button unless necessary. I unlock with fingerprint, and lock with Greenify.
In other words. Make sure of it, if the button starts working funny, I'd file a warranty claim. Or it won't last long and warranty will expire eventually. It can happen with this device and with any other piece of tech.
My opinion.
If you do place a warranty claim, let us know how xiaomi's customer service works in Europe.

when you dropped it
the power button may have got stuck
this is possible and I've seen it on some other devices
you can open it yourself if you don't care for warranty like i do
but the safest option is to claim warranty and yes they would replace it

I have the exact same issue. It started when I installed the Oreo update, but it could be a coincidence. I'm still looking for a fix.
It also happens to me, and I didn't drop the phone... Is there a way to change the shortcut to, maybe, press the power button 3 times instead of 2?

It happens to me too, I disabled the shortcut and just not using it right now. I don't think there is a way to change the shortcut

And i think it's a software bug, not hardware..

It obviously is not a software issue. This means that they've used cheap contact points on the button if this happens to many of us. This is a hardware issue.

I'm having this issue since day one. It is obviously software, otherwise the same contact problem would occur when turning the screen ON, but it never happens. Solution is to disable the feature under System -> Gestures -> Jump to camera.
i also dissabled the camera gesture because of this issue.
im sure this is reasoned by a more or less loose power button and not an software issue

How can that be a software issue? Same issue happens to me whenever I use the power button, either to lock the screen or unlock the screen. Also if it was a software issue, it could be fixed via installing a GSI. That doesn't fix it either.

Let me break it down and you can tell me if I'm missing something.
1. Many users are reporting that the camera app starts when pushing the power button to turn the screen off.
2. They are not reporting any other issue with the power button, like the camera app starting when they try to turn the screen on, the button being irresponsive, or the camera app NOT starting when they deliberately push the button twice.
3. The problem reportedly goes away if the double-push gesture is turned off in settings.
Do you still think this is a hardware issue?

When I disable double press gesture from Gestures, still when I sometimes hit the power button, the phone locks and closes the screen and then turns the screen on again which means that it still registers one presses sometimes as double presses. Also if you've ever used a keyboard or a mouse or anything electrical with buttons on it, these appliances do the same sometimes even though you tap one button they sometimes register it twice. Which is a hardware issue. I still can't see any software issue here. When you disable the double press gesture, it doesn't launch the camera anymore but it turns on the screen after locking it (sometimes as usual)

Yeah me neither. They don't look like they're going to fix anything or listen to users either. I'm happy with stock Android though.
Hi guys, for me, the problem has fixed disabling the option "Power button lock the phone", and set the option "Lock automatically": immediately.

I changed the power/volume button assembly outright just the other day, and so far I'm not getting this issue anymore.
I recorded myself doing it here, so you can see how easy (or hard) it is: https://youtu.be/q8kaY-v0q_Q
