Hi to everybody,
Two months after to buy my Z2, I made the mistake to put my phone on my legs and it fell. Result: my screen has crashed
I sent it to repair and the technical support changed my screen,
All is now working fine, less the "double tap to wake" option.
I installed the last update to know if i could fixed it, but it still no working.
Any one know if is the double tap managed by hardware? (the screen maybe?)
Thank you so much!!
Ps: Sorry for my english
This feature has never really worked relatively well for me anyway
While sometimes it works other times I find myself tapping the screen repeatedly with no effect
Not sure about your issue as if the touch screen is working then I can't see any reason why the touch shouldn't work as well as it did previously unless it's a cheap replacement not an OEM

I sent my phone to official technical support in Portugal, so in theory the screen is OEM
Thanks for answer

Have you tried doing a factory reset? Maybe it will help. This function is kernel related so it should work, unless the screen is not like the original one. Just saying.
No I didn't.. I only installed the last update by Flashtools

Well that means your screen should be okay. I tried tap waking my Z2 and it responded every single time, with really fast taps and slow taps, so something is definitely wrong with yours. Problem is I can`t tell what...
Well.. I hope that with Lollipop it will be solve..
Tip with this matter, you have to "knock" on the exactly the same spot both times. Then it works much better.
No way [emoji17]..
I tapped for 10 times consecutively but nothing...

HI, since I've always had issues (from stock rom up) with hw capacitive buttons (home/back/search/menu), I would like to disable them, maybe my Folio is faulty on them (randomly the back button fires by itself, even if the tablet was left alone on the table).
So I ask Artem or anybody who knows it: I can build from sources, what is the minimal diff I can make to the sources? Is it sufficent to comment out line 'CONFIG_KEYBOARD_FOLIOCAP=y' in tegra_betelgeuse_android_defconfig?
Thank you.

may be its a bug....
when this happens to me, i click one time on power buttom and than wake it up again. but this isnt the fix solution for the problem, just solves it temporarely
ans solution?
one "solution"
Hello, posting for the first time =)
Anyway, i've had a problem with folios crazy buttons and screen response since day one.
Nothing really changed for me with rom updates and different apps. I have tried it all...
I had enough and finally unplugged that little cable that connects into circuitboard
of those buttons and power-led. This is really no solution but takes care of that problem =)
It also disables power indicator led, so that's a little inconvenience =/. But since unplugged,
touchscreen started to work in every way better like its more responsive and doesn't "freeze" anymore.
But this requires you to disassemble your folio to get to touch with the cable to the circuitboard.
Removing plastic back cover isn't enough, but you Dont have to detache the screen from faceplate.
I'll plug it back on when there's a software fix for buttons behavior. Meanwhile enjoying peace from
button madness =D. Sorry if poor english, i'm Finnish

I'm using mouse and keyboard and it's comfortable.
Hi,
I'm looking to try out a Note. But want to know if there is a feature in some kernel or flashable zip of some kind to achieve this. I searched around but got mixed results so I'm not certain. thank you in advance.
I remember having that option on my Vivid. However, I do believe that is an HTC/Sense option. Someone correct me?

Whoa, funny to see 2 other people switching from a Vivid to a Note!
This is something I'd been looking for a while as well, never found anything. It was such a nice way to turn on/off my screen, made the button seem ancient and obsolete.

well, not just a note but just something a bit bigger than the vivid, i'm even considering the GS3 as well. but the thing is, I dock my phone onto my car's instrumentation panel and it seems to work well but there's no way i can get to the vivid's power button, and even the samsung lines would be difficult to get to as the power button is on the side; i hope someone can make something like this for the samsung lines.
thanks.

It doesn't really need to be 'swept' to wake. all I want is something that I can touch (or hold) on the front screen or bottoms to wake this thing up. anything? if not, I think what I'll do is go for the international version which, its middle button wakes the note up.
thanks!
you can flash a cm based rom and set device to stay awake while charging. you can also set to wake with volume keys. unless you mount phone with both sides blocked. i personaly set to stay awake and have modified my sunglass holder to hold phone. sits just above rear view mirror and works great even though power button is down and cant be pressed. if you want to stay with touchwiz screen times out at 10 minutes and no option to stay awake. however if you have sqlite editor you can change the database to stay awake but i have had issues with this not wanting to stick after reboot.

so you want to wake/unlock the device without using any hardware buttons?
i use lightlock or proximity screen off/on from the play store. it uses the front sensors to wake/unlock or sleep.
i set lightlock to just 1 sec so all i have to do is put my hand/finger over the front sensor then my note wakes up

Does this mean it wakes up in your pocket?
no. it will only wake if it senses a proximity change
so if you use lightlock and just cover the sensor, nothing will happen. if you cover the sensor for a set period that you choose and then remove your hand, then your device will wake.
you should try it out. it makes using your phone feel futuristic. impresses a lot of people especially when you show somebody with an iphone lol

thank you so much! I will check this out. this will work great. yeah i can now go look for a Note!!
and don't need to look for the international one, which seems to be more expensive.
What I found out is that the timing of the two knocks is less important, what is more important is to keep the finger on the screen after the second knock. After the second knock just keep it on the screen until you see the LED lights up, and you'll see how more efficient it will become.

Gesendet von meinem LG-D802 mit Tapatalk 4
I noticed most of the time when Knock On fails for me is because the phone isn't on a solid flat surface for example while I'm holding it in my hand or while it's on my bed.
This makes me think the accelermeter is used for this feature. So if you have too much "suspension", it won't trigger.
Just my thoughts!
Edit: I just tested with incredibly light touches and it still worked so perhaps it isn't accelerometer enabled. =S

Great tip
Exactly what i was looking for although still a bit slow compared with what i had with my Nexus 4 and the touch control app. But at least I just do Knock knock once.
That really does work everytime.
Nice tip. I have been playing around with suggestions that I have seen elsewhere but yours seems to be the most consistent (I've done it 25+ times now in a row with your technique). I've even tried changing the rate at which I do the knocks (fast versus slow) and have also tapped on different parts of the screen. It seems like the key is leaving your finger on the screen on the second knock.
Previously some things that I read to increase the success rate were (each with mixed results):
- Always tap on the top of the phone (where the notification bar would be)
- Always tap three times instead of two
- Tap once and then pause slightly and then tap twice
On a side note, does anyone know how this feature works exactly? Is it simply the digitizer detecting the taps on the screen or is there something else going on?
I tried tapping on the back of the phone. This didn't work so the at least use the touchscreen for the knock knock feature.

Ya, after doing some more testing, it must be the touchscreen. The reason I thought it may have been something else is I have gotten it to work by tapping in the top right corner of the phone (presumably not on the screen) but that's probably b/c the bezel is so small. I haven't been able to get it to work along the bottom of the phone (over the LG logo).

I hate it bc that's how I was when the first iPhone came out...made me want to pinch to zoom my laptop screen. Now I find myself tapping the iphone or laptop to unlock but get mad when they don't lol
Knock On feature to turn screen on doesn't work if proximity sensor is covered (try to cover it and tap the screen - it will stay off). Also phone needs a short while to detect the sensor is not covered anymore. So if you pull out your phone out of a pocket and immediately try to turn screen on it simply won't work at first try. Second usually does the job. I've never really had a problem with unlocking the phone while it's on the table or something, when the sensor isn't (or wasn't two seconds ago) covered by anything.
So the reason of our problem is slow response from proximity sensor, it's super fast to detect the sensor is covered, but a lot slower to detect it's uncovered. (You can test it during the phone call - you'll see what I mean).
The solution is just wait a second after you pull out your phone from pocket or after you holding it the way it covers or is near the proximity sensor. I don't think guys triple knocking or keeping your finger on the screen is really helpful. ?
Maybe it can be fixed somehow by our devs, make the proximity sensor reacts quicker.

Probably does that so it won't come on by "knocking" in your pocket. Not a big deal for me at all. And the OP's method is working 100% of the time fur me. No need for 3 knocks any more.
I'd like to confirm what don't others have said and say that the most common mistake is tapping too fast.
Correct that the knock on only uses the sensor to avoid turning the screen on in your pocket.
However, if the touch screen constantly listens for these knocks while it is turned off, shouldn't that consume at least a considerable amount of battery?

sorry for this really really dumbass question but when u say "After the second knock just keep it on the screen until you see the LED lights up"
i infer 1 knock (tap and lift finger) and then 2nd one is not actually a knock (tap and lift finger) but just tap and keep ur finger there itself
or
is it 2 knocks and then (after second lift of finger) jst touch the screen again
good i really feel like dumbest dumb on this planet asking this question but please do reply
i dont yet have g2 but planning on buying it so i cant confirm myself what u meant
My phone is currently running everything stock , I am considering rooting my device !
one of the primary reason is to get the knock knock - double tap to wake and sleep the device .
the question is , is it possible to get it on the ZU after rooting .
Hopefully there are no issues rooting ZU on 4.3 , if any please mention
thank you

Ok, maybe I should have said search is my (or the collective forum) friend, as the question has been asked and answered several times that there is no knock/knock to wahe port for the XZU
We'll get the "double-tap-to-wake" feature in the 4.4 update according to the latest Sony 4.4 screenshots leak (xperiablog.net).

The idea came my mind when i read that the knock knock feature was ported to HTC ONE through flashing something , so I thought if this could be done for the XZu it would be awesome !
and since I am coming from the jailbreak family i couldn't do much research about the true capabilities of rooting !
It's not Knock Knock, BUT:
I use the Gravity Screen app. On stock settings, it will turn off your display when you cover the proximity sensor and you tilt the device a certain angle, like when you're putting it in your pocket.
It will wake it up again once the prox sensor detects that nothing's covering it, like when you take it out of a pocket, or flip open a wallet case. You can play with the different settings to make it work however you want.
In my case, I've set it up so that if my phone is lying on the table, I can just tap/hover a finger (or palm/entire hand) over the proximity sensor and the screen will activate. Just like Samsung's implementation, or indeed Knock Knock. In my case though, it just takes one...knock.
No more wear on the power button. For turning the screen off, I use the Screen Off app (double tap with Nova's gestures). Or if I'm putting the phone in my pocket, the screen turns off automatically once the top part goes down a certain angle.
Hope this helps.

I have just registered with xda forum so I think my reply may be quite late, but it's never too late, so they say
Anyway, I had the same issue with Huawei P Smart that I've just bought a few hours ago. And I got it resolved with the app called "Smart Screen On Off (New)", by LuuTinh Developer. You will find it on google play.
As long as you test the proximity sensor physically and it works fine, this app should help you get your problem disappear altogether
Happy calls (with a turned-off screen obviously )
