Hello everyone,
I'm having issues with my Xperia Z5c and its double tap to wake feature.
Sometimes it just doesn't wake up the first 2 or 3 times and it needs 3 or 4 attempts.
Sometimes it works on first try.
I don't know why and it's annoying.
I use a tempered glas screen protector, but I have no sensitivity issues at all during normal use. And someone in another forum stated that he uses a glas protector and has no issues with tap to wake.
Any ideas?
Thanks & regards

I run my phone naked and have the same issues. I've disabled the fingerprint scanner as I just check the time often and the double tap thing really doesn't like to work after its been locked for longer times.
Sometimes i need to double-tap 2 times but maybe it's related to the speed of the touch. Never needed 3 or 4 times, tough
Tap-to-wake has never worked well on my Z5C. I usually have better luck tapping three times instead of two.
I have both a z5c and a z5p dualsim and both experience the same double tap to wake issues. No screen protectors on either. I've tried glove mode which didn't make a difference. The best thing that works for me is using my thumb for tap to wake. I can tap 5 to 10 times with a finger and it sometimes works and many times it doesn't. Tap two times with a thumb and it wakes up. Smh

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.
Im tapping on every other device since I have my LG!

Excellent information; exactly what I was looking for. Thanks!
Yeah works good so far!

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?

this is an excellent tip, thanks! I went from knock knock knock knock, to knock knock and hold and its worked every time for me..
Exellent tip thanks!
Works 100% of the time now! :good::victory::laugh:
This tip however, does not apply to turn off the device. Two quick taps (and release) takes care of that always!
Cheers!

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
I've noticed that the double tap to wake feature isn't always very responsive particularly the first few times I try to tap to wake. I do have a screen protector on the device and am wondering if this could be part of the problem. I've even tried to set it for glove mode to make it more sensitive but it didn't help. Any suggestions?

Well it might be the problem. I see some struggle even without screen protector, but I have no problem. Just remember to tap in the exact same spot both times, and not too fast.

Its better if you double tap with an index finger. Using a thumb is harder because the angles vary easier when you double tap.

Its working for me all the time, you have to tap the same place
Had the same problem I guess my thumb wasn't tapping in the same spot twice. Will try the suggestion.
So after some more use I still felt the double tap to wake up on my Z2 wasn't as responsive as others said theirs was and I had to tap pretty hard some times and even then it wasn't working all the time. Well anyway...decided to take the screen protector off because it was slightly crooked and was bothering me.
Not to mention the screen just feels so much nicer with out one all though now I will likely have to deal with a few small scratches. I've noticed some small ones on the back just from regular use. The thing is very delicate in that way it seems because I'm very gentle with it.
I was using an iSheilds screen protector which was the only one they had at the Bell Store when I bought the phone. Just wish I hadn't wasted that money.
So if anyone else is having this issue I suggest they consider there screen protector.

It's a little bit non responsive if I use the tip of my thumb. Though tapping it with the whole thumb works well for me.

if the phone is on a hard surface then i find the double tap to work about 8 times out of 10 .. if your holding the phone or its on a sort surface .. forget it ! im tapping at it like some demented woodpecker on speed trying to wake the b****y screen up ! i now use the on/off button , yet another thing that a so called flagship phone falls down on.
Same problem here, it's very unreliable especially coming from the HTC M8 which had 99.9% reliable wake gestures. I just use the power button now.
FYI, you don't have to tap very hard at all. It's more important to get the exact spot both times and for me personally, an area in the middle of the screen seems better than on the outer edges. I barely touch mine twice and it works.
Double tap the same place and no too fast does solve the problem.
You just didn't tap it right.
I've managed to make it a bit more reliable. Tap quickly, gently and in exactly the same place.
Try triple tap, it works most of time.

It would be a nice feature to desable power button and leave only double tap to wake so that other people are unable to wake the phone
triple tap
Is there any way to turn the screen on by tapping three times (triple tap instead of double tap)?
anyone having trouble with turning the screen on? its like 1-5 doesnt work. im deliberate with my tapping. off works no problem. but turning the screen on does not work every time. please let me know if this is just me.
Seems to happen most often after the screen has been sleeping for little time (like over 2 mins).
I have had this issue several times. Sometimes I'll sit there and try it 3-4 times in a row, then it will magically work. I usually try and explain it away, thinking perhaps I just double tapped too quickly in a hurry.

Yess exactly. I keep thinking maybe I messed it up. Maybe a part of my hand was pressed against the side bezel and screen or something. To the point I'll lat it in my flat hand and trouble tap it like a science experiment lol. Thanks for the reply. Anyone else??
Mine occasionally does that but I have one of them Zagg Glass screen protectors on and I think that's all it is. I played with it for a few prior to putting it on and it wasn't like that.

I'd say I agree with this. So is this a problem or do you have to double tap at a certain speed or in the same spot twice?

Generally it comes on if I tap once, wait a beat, and then tap again. It will sometimes come on if I grab the phone and the side of my hand happens to touch the screen twice. And sometimes it will come on if I tap it twice really fast, so there doesn't seem to be any rhyme or reason to it.
Also make sure u don't have a finger even close to the proximity sensor. That will keep it from coming on. On my g2 if I had my finger even at the top of the phone next to the sensor it would not work.

I've had some issues with it mostly assuming it was a little lag or whatever not a real problem to worry about, but I have noticed that it likes the taps to be close together on screen. So tapping in the same place more or less twice works best. So. Two taps being an inch apart it doesn't like. This may be some of your issues, sloppy tapping not close enough together may cause issues. I'd say it really doesn't like anything more than a half inch apart.
Hi guys, just a quickie,
So I've enabled double tap to wake on my Z2, but sometimes it takes up to 10 taps for the device to wake up. Can a screen protector make the difference here? Or is it normal?
I notice the same thing sometimes. What I find is if the phone goes into a deep sleep (screen doesn't turn on for say 10 mins), it takes more than 2 taps to wake it a lot of the time. But if you turn the screen off, and tap twice within a few seconds, it works most of the time. Just my observations though.
Tapping a little bit harder works most of the time for me
Yeah it's the problem with deep sleep. I saw the same thing on many other devices. HTC One m8 and LG G2 Mini for example. Most of the time it's triple tap to wake
I found out that I was tapping way too quick.
Try tapping really slow, like once per second, and it almost works every time.
But it sucks because it is slow because of that, going to the power button is faster....
I usually just tap the screen until it turns on, but messes my PIN up good to know that it's not only my screen that's cold hearted to these poor little taps though
sometimes the indisplay Fingerprint sensor stops working at all.
The display wont recognize any touch and stays black.
If i push the Power button it starts working again.
This happens sporadically, 1 -3x a day
Did anyone had the same Problem?
Any suggestions?

I haven't seen this problem. I use face unlock along with it and it usually recognizes my face before I can even scan it.
When the screen is black, you can put your finger on the display and some glowing circle Appears. This does not appear to me at all. The screen just stays Black.
Thx for the information.

Maybe your fingerprints got erased somehow? Does your phone display a fingerpring icon on the screen a second after you turn the screen off?
Sent from my LYA-L29 using XDA Labs
Yes the second I turn if off it shows a fingerprint sensor. Just after a while it won't toggle the sensor if I touch the display. It's like the fingerprint sensor is deactivated. The second I turn the display on manually it appears again.
Hello! I've got the p20 pro and now I'm testing mate 20 pro. Sometimes I'm not able to unlock the mate with my fingerprints at all. Same finger. The p20 works perfect, just touch and unlock. Mate sometimes I have to touch it 3-4 times before it unlocks , sometimes it doesn't unlock at all? Is that normal? The display was exchanged already because of this issue.
I believe you guys are not the only one. This on screen finger print is not reliable. I guess because they are new and will improve over time. Personally I just use face recognition than finger print. They are a lot more faster and accurate to unlock.
I know it's an old thread but it's happening to my M20Pro right now! It's awful! The screen is protected by a tempered glass made by Spigen (maybe this glass has issues?). I reconfigured the fingerprint and I touched almost 50 times until the phone captured the fingerprint! What's wrong with that sensor?!
I had problems with glass protector, if you can get plastic film it is fine, glass you will have problems....this was my finding

If you still have this phone and problem: I have a P30 Pro, and/but the reason I write here is because our phones share the fingerprint technology, and I didn't find anyone mentioning this problem regarding P30 Pro. So:
I have the same problem - seemingly sporadically the fingerprint sensor (or screen) wont react until I press the power button. Then I noticed that when the brightness/proximity sensor (located near the top right on the P30 Pro, and next (right) to the upper speaker on Mate 20 Pro) was covered, the screen would get unresponsive. I guess this is by design, to not accidently let your phone come to life in your pocket. The problem was/is that the proximity (?) sensor is way too sensitive - any obstruction at about 2 cm (0.8") above the sensor(s) will trigger this behaviour. I also think it can be triggered under other circumstances; I had som weird fingerprint/screen behaviour in a store with a high and very dark ceiling, but I have to test this again, so don't take my word for it.
Anyway - if anyone is having sporadic problems - see if this could be a reason.
Edit: Well, sometimes my screen is just totally unresponsive even without sensors blocked, so ... I noticed it a couple of times after digging my phone out of my pocket, suggesting it could still have something to do with the sensors turning the screen (functions) off. I'll try to see if I can make it behave the same way in other scenarios.
I have also been experiencing similar problems on my mate 20 pro, But mine is more of an accuracy problem. sometimes its on point and registers instantly. and other times it just doesnt at all.
However i have noticed that in extremely bright weather i have more issues, fingerprint doesnt read at all, and face ID is also doesn't. My finger print issues have started only after EMUI 10.1, so i suspect that it could possibly be a software related issue
