Hi

I'm having a really unbearable problem with the headphone jack - any slight knocks to the headphone connector cause the track to skip or pause - as if I were pressing buttons on a button controller. My headphones are mid-range Shures (i.e. high build quality) and do not cause this behaviour on other phones. Has anyone had anything similar? Or have any suggested workarounds? It makes it basically impossible to use the phone to listen to music with whilst walking...

Many thanks

That's funny when I knock mine sometimes it goes to voice activate what bugs me
[G3 Q&A, Help & Troubleshooting] konsta819:
Yes: I get that behaviour too.
[G3 Q&A, Help & Troubleshooting] konsta819:
Took mine back to the shop for a replacement. Seems to be fine on the new handset.
[G3 Q&A, Help & Troubleshooting] dvernst:
Same problems here. Returned the first one to Best Buy,and the new one has the same problem. It's it just a software update to fix it?
[G3 Q&A, Help & Troubleshooting] xedahh:
Same here. Touching or slightly tapping the headphone plug either pauses/skips the track or opens up Voicemate (which cannot be disabled in settings). There has to be some software running that 'manages' audio connections.

I tried LG support and they didn't address the issue at all but said it might warrant an RMA.
[G3 Q&A, Help & Troubleshooting] kinnyfaifai:
Mine was fine for two weeks and just noticed the problem today. It's highly frustrating.

Update: noticed for some reason sometimes when the headphones are plugged in it recognises it as a headset and thats when knocking the phone jack either triggers voicemate or skips tracks. If you get it to recognise it as headphones it seems to be fine.
[G3 Q&A, Help & Troubleshooting] dvernst:
Same here. Sometimes with my audio cable it recognizes it as headphones. Sometimes when I plug in the audio cable it doesn't work at all unless I unplug it a few times. Overall volume for audio cable and Bluetooth is pretty low too.
[G3 Q&A, Help & Troubleshooting] kinnyfaifai:
Last two days the problems got worse for me to the point I can't get it to detect my headphones properly, always a headset. I did notice however that if it detects it as a headset the volume would be quieter even on the same sound setting.

To stop the annoying issue for now, as I use PowerAmp, I have enabled the PowerAmp lockscreen widget and disabled the headset controls. As I never use a headset (BT or otherwise) this seems to have stopped the knocks skipping tracks for me.
[G3 Q&A, Help & Troubleshooting] homer285:
Yep I can confirm above fixed issue and besides PowerAmp S**ts on stock player.
[G3 Q&A, Help & Troubleshooting] jsauce75:
I have only noticed it in my cars when listening to Spotify . I use an aux port and a 3.5 mm cable in both. My issue is the phone not recognizing a cable is plugged in some of the time. I have to repeatedly unplug and replug until it recognizes it. Seems to work better if I unplug from the stereo rather than the phone. It had also kicked off a few times between songs. So far it's been fine with headphones, but very limited use, so inconclusive. I'm not sure if the cause, but stinks of a software bug.
[G3 Q&A, Help & Troubleshooting] stevemiddie:
Same here except it happens when I'm using Google Maps to navigate on my bike..........any little bump on the road and it goes to Voice Activation. It's really annoying and frustrating
[G3 Q&A, Help & Troubleshooting] Pheno.menon:
I have to unplug and plug the cable several times in the car before it will recognize an aux connection. Thinking of trying a different cable, who knows, it might help. But it does sound like a software problem rather than a hardware one

I've tried 4 different cables, they don't seem to change the results unfortunately.
[G3 Q&A, Help & Troubleshooting] stevemiddie:
I contacted customer service (UK) regarding this matter. This is what they replied and I quote:-

Hi Steven,

Thank you for your query regarding your LG G3 (D855).

After reading through your email and looking into this for you I can advise that the problem you are experiencing is going to be down to the phone using the KnockOn Function against your leg. In this instance we would like you to try and face the phone screen so it is not touching your leg when it is in your pocket and to make sure there is nothing else in the pocket with your G3.

This could also be affected by the Genuine LG G3 head/earphones not being used. Please make sure you are using the correct Head/earphones whilst performing the above test.

If you still experience a problem after doing this then we would highly advise for you to contact us back so we are able to investigate this further and resolve this for you.

We hope this works for you Steven.

I hope my email has answered your query and assisted you today; I would really appreciate your feedback. Please help us to improve our customer service by completing the short survey after this email.

Thank you in advance.

Kind regards

Josh

Same problem

I am getting the same issue where Headphone jack: slight knocks change track.

I read Stevemiddies post about what LG said. (good work Steve for raising to them) and I dont see how it be down to the "knock on". I have taken phone out and cant replicate issue by "knocking" the phone anywhere. But the smallest of touches on the headphone input to the LGG3 causes it to pause or skip tracks...

I also read Kinnyfaifais post about how using poweramp can stop this. Great bit of advice. but i dont really want to have to pay for poweramp to fix an issue which LG should fix..it cant be right that a phone with headphones cant be put in your pocket!!! I have the quick circle case too.

COME ON LG lets see a fix
[G3 Q&A, Help & Troubleshooting] stevemiddie:
For sure the response from LG was not really relevant to this issue.

I have used my Shure SE 535's, Sennheisers, Klipch's and of course the LG supplied headphones. The problem remains.

I don't believe it has anything to do with the 'knock code' personally. The problems happen every time I move the headphone jack at the point of entry to the phone.

I also have the Poweramp Pro version but despite following previous posters advice, it has not resolved the problem.

It remains deeply frustrating.
[G3 Q&A, Help & Troubleshooting] kinnyfaifai:
It didn't solve it for me in the end either. As I have root, I disable VoiceMate through TiBu. I agree it's highly annoying and LG needs to address this issue.
[G3 Q&A, Help & Troubleshooting] jsauce75:
Does disabling voice mate fix it?
[G3 Q&A, Help & Troubleshooting] kinnyfaifai:
Yup! :) It seems to have stopped it, not triggered at all since I disabled it.
[G3 Q&A, Help & Troubleshooting] jsauce75:
I am not rooted. I was able to uninstall the "voice mate engine". On my limited testing so far, the problem seems to be gone. I'll verify this week, but things are looking up!

Edit: spoke too soon. Issue still exists.
[G3 Q&A, Help & Troubleshooting] MarvinFS:
yeah still there for me also after completely disabling all the voice mate apps
[G3 Q&A, Help & Troubleshooting] wobmob94:
I have had the same problem for a while and found a fix that works for me (didn't read this whole thread, might have been told already but i'll go ahead anyways.)

When i plug in my headphones normally the headset symbol will appear and skip/pause/vioce control at every slught bump. When plugging in the headphones really slow the phone will display the headphone symbol and not the headset in the status bar. Whith the headphones symbol i can push the jack anyway i want to and nothing will happen.

I do not use a headset nor do i use headphones with media control buttons, just standard headphones with a normal cable.

Hope this might help some of you, sorry for my not wuite excellent english ;)
[G3 Q&A, Help & Troubleshooting] P@nd@:
Nice to know that it worked for you, wobmob94. I just tried doing this on mine and it didn't work: my headphone is still identified as a headset and the smallest touch on the headphone jack either pauses or skips a song or activates voice mate. I also tried some apps that claim to block headset commands, but to no avail. It is a REALLY annoying bug in an otherwise splendid phone.
[G3 Q&A, Help & Troubleshooting] labpedro:
Mine has gone mad today..had a glitch earlier that caused an issue with the screen making it flash/flicker like a light bulb that's bust. since then that has stopped, however the headset icon shows up as soon as I plug my headphones in, and that damned annoying voice thing pops up. if i plug my headphones in with the screen off its fine and doesn't show up as a headset. very poor and as three haven't released any firmware upgrades I'm stuck, although that probably wouldn't fix the issue either.

I've got a returns envelope coming from LG so will send it back and ring them with an update to the issue. poor show though :(
[G3 Q&A, Help & Troubleshooting] Ying27:
I had this problem too with all my headphones (Bose, Sennheiser, Beats) but using the SmartKey app ( https://play.google.com/store/apps/details?id=com.sonymobile.extras.liveware.extension.smartkey ) and configuring all the options to "No action" worked for me, however you won't be able to use the headphones buttons anymore but in my case it doesn't matter because are normal headphones without mic and controllers.

headphone audio and other issues

I bought my G3 from Verizon the week it came out. over the next two weeks I experienced:

the phone display freezing - tried everything to turn the phone off but it wouldn't shut down. Finally I called from another phone and that unfroze it.

Samsung earbuds stopped being recognized by the phone, but Apple earbuds are.

This anoying electrical buzz in the earpiece when making phone calls, not through speaker or bluetooth.

The phone randomly being very slow and sluggish. A restart would fix it.

So after all that I asked them to replace the phone. My new phone the buzzing in the earpiece on phone calls is still there, it's not a network thing because I got my wife the same phone and her's is crystal clear. Just now it started opening the voice assistant and switching tracks with the slightest movement of my B&W P5 headphones. Hopefully this is a software fix Lg!! Audio is just as important as the beautiful display. I'm sure people listen to more music than watch movies. Good phone but please work the bugs out Lg!
[G3 Q&A, Help & Troubleshooting] TonnyRockyHorror:
Hey

I have the same problem and I thing it is quite naive at think that it is software problem. We have just broken headphone port couse it's made of poor quality.
[G3 Q&A, Help & Troubleshooting] cheesebanana:
same issue here, extremely annoying.

clearly just a cheap headphone jack

made it bearable by installed headset button controller, setting everything to disabled

then force stopping voice mate and clearing all data

when voice mate does try and launch, t just asks you to accept the terms and conditions, no interference

plug in and out

I have some audio technica ath-m50x's and they worked amazing on all of my devices except my g3 because of this problem. I noticed it was detecting the headphones as a headset so up to this point I have to plug them in and out several times until the icon at the top looks like headphones instead of a headset. I suspect this is a software flaw and there's not much we can do about it.
[G3 Q&A, Help & Troubleshooting] lossah:
More mail to LG about this! They really need to fix this. They released a lot of firmwares and not a single word about the aux problem.
[G3 Q&A, Help & Troubleshooting] submin_:
Same problem here. I would've frozen VoiceMate, but it won't show up on any frozing apps. It does show on TIBU, but as I don't have the paid version it doesn't let me freeze it, and the uninstall option says "apk not found" :p Naturally I am rooted.

I'll probably take my phone to the service shop any day now, let's see if they can do something about it.

This is the most troubling thing I've read about the G3. I'm planning to get one in the next day or two, but now I have my doubts. If I do go ahead I guess I'd better check all my headphones and aux cables right away.

FWIW, my Sprint LS990, which I got on Wednesday, doesn't seem to have any issues with this. I've tried 4 different sets of ear buds and all work fine. 1 set has 3 bands (4 conductors), the other 3 two bands (3 conductors). They range from a cheap unbranded pairs, through a pair of old iPod 'phones and Sony phones with buttons to control iPod / iPhones, through an expensive pair of Etymotics. The phone recognizes them as 'phones, and no amount of wiggling or tugging on the connector or wires causes any issues. I have a Sony pair, and a Samsung pair that I can try, but won't get to where they are until Monday.

[G3 Q&A, Help & Troubleshooting] brainalive:
variation in jack-size / fit

I'm having this issue as well...

I opened up my device to see if I could find any issue with the jack itself (a bent pin or a loose connection or poor seating or the like). I found no problems.

I was intrigued by the report that this happens with some headsets and not with others, so I've tried a few sets myself and here's what I think is going on when using a headset WITHOUT a microphone or button-controls.

The 1/8" pin on some headsets sits loosely enough in the jack that the pin can move and intermittently touch the extra contacts that are used for button control / microphone input. When this happens, it triggers unwanted stuff... BUT ONLY if the phone has recognized the headset as a "headset with microphone". This happens when the contacts are touched AS the pin is inserted. Perhaps this is the reason that (as one previous poster reported) inserting the pin slowly into the jack prevents the unwanted behaviors: going slow reduces the likelyhood of touching the side-pins on the way in. However, my guess is that the pin on some headsets has a shape that makes it essentially impossible to insert it without this happening, which wouldn't be a problem if the pin didn't also sit loosely enough to make intermittent contact.

I see a couple options: (1) find a pair of headphones that work consistently (I hate this option as I have strong preferences for certain types of headphones and already have several hundred bucks worth of headphones that I don't want to repurchase). (2) physically prevent the contact patches dedicated to microphone/buttons from touching the headphone pin. (3) ensure that the pin sits snugly in the jack.

I like (3) the best, perhaps an insanely small rubber grommet inserted into the casing by the headphone port will keep it snug? Of course this requires that the geometry of the pin is going to work. I'm going to try it out and post my findings.

I've used at least 4 different sets of earbuds with my LS990 (Sprint) G3 and haven't had this problem at all. Some are 4 conductor, some are 3, some are really cheap, some are quite expensive. Don't know if it's the Sprint version that's different, or I'm just lucky.
[G3 Q&A, Help & Troubleshooting] TheTenth:
Well I have the same issue with D855 and with all my 3 conductor-plugs (and I believe it started when I updated from v10a firmware to v10h 'cause I remember having used my Jays headset (no-mic) without any problems). Although it works ok when plugged into my car aux input. :confused:

[G3 Q&A, Help & Troubleshooting] acparker18:
Okay buddy. This is your first post on this site so don't call these other guys with far more experience than you naive. It more than likely is a software issue because it has to do with how LG's software detects what kind of audio device is being plugged into the phone. Personally, I think the build quality of this device is very good.
[G3 Q&A, Help & Troubleshooting] wobb:
The problem is, that it is a hardware problem of it being a ****ty port. Like the poster before wrote I think the problem is about the port being too loose and button pins getting touched on insertion makes the phone detect regular headphones as a headset. I have learned to plug my headphones in a way that allows me to consistently get them detected as headphones and not a headset by angling the pin away from the LG logo at the bottom of the screen. So it basically is just a cheap ****ty port.
[G3 Q&A, Help & Troubleshooting] codified:
I only got this problem since updating to the L firmware. It's really annoying, basically cant use the phone for music now because any slight knock will pause or change the track. :crying:
[G3 Q&A, Help & Troubleshooting] Mattbartlett303:
My g3 recently started showing all these problems. It seems to be a hardware issue on my handset. If you use headphones without inline controls the Jack shorts the contacts in the socket as you insert it and the headset icon appears resulting in unwanted pauses and activation of voice assist. IF YOU TOUCH THE TIP OF THE JACK TO THE FRONT OF THE SOCKET (SIDE CLOSEST TO SCREEN) AS YOU INSERT IT, THE HEADPHONES ICON APPEARS AND THE AUDIO PLAYBACK IS FINE. If you touch the back of the socket with the Jack as you insert it the headset icon appears along with the problems.

It works everytime on my phone, I hope this helps some of you.
[G3 Q&A, Help & Troubleshooting] meyerweb:
I don't claim to know what the cause of the problem really is, but my LS990 works fine with 3 or 4 contact earphones. I use it at the gym all the time and have never had any of the problems described in this thread. Knock on wood.
[G3 Q&A, Help & Troubleshooting] leomd333:
I made a thread on the same theory as you a while ago, I 100% agree it is to do with the number of channels the Jack has but also a bit of software work from LG that needs doing haha!

I think there is something wrong with the software that does the detection.

I'm using the Illusion ROM, but I was still having issues with it. I ended up going to /system/usr/keylayout and commenting out all the lines in Button_Jack.kl (after making a backup, of course).

[G3 Q&A, Help & Troubleshooting] Tomogitarist:
That happens with older headphones that got a bit old and lose signal while twitching at the headphone jack. The cause of that is sending the signals which phone interpreters as activating google voice, prev/next song or pause song.

Only real solution is to buy another headphones. It isn't fault of the phone.

Headphones problem

I rooted my phone and disabled Google voice. Make sure you are using a 3 pin headphone jack. This will sort out the problem. It was very annoying. It has been sorted now.
[G3 Q&A, Help & Troubleshooting] codified:
This is the solution (if you have a rooted phone)

On your rooted phone, make a backup of the file

system\usr\keylayout\generic.kl

Then edit it to comment out the line beginning "key 226"

- i.e. change :

key 226 HEADSETHOOK

to

#key 226 HEADSETHOOK

Restart your phone

Works for me. No more jumping or stalling of music. Tried with five different headphones. Two of them are still incorrectly detected as being headsets rather than pure earphones, but none of them skip any more. Finally my phone is usable for audio again :highfive:

On the negative side, you lose some headset functionality - the volume controls and mic on my LG Quadbeats still work, but the middle button doesn't seem to do anything any more. A price worth paying IMHO.

[G3 Q&A, Help & Troubleshooting] labpedro:
That's total codswallop....I have tried a variety of headsets, and all do the same, including a brand new pair of ear pollution phones. The issue is that the headphone socket cannot see the difference between a headphone plug (2 lines) and a headset plug (3 lines). This is a hardware issue, not a headphone issue. Whilst it is highly annoying, it doesn't stop me from saying the g3 is the best phone I have ever used.
