Nexus 6P headphone jack problem - Nexus 6P Q&A, Help & Troubleshooting

I recently bought a used Nexus 6P and I knew that it had problems. I resolved all of them except that the phone thinks that the headphones are plugged in. When I bought it I thought that it was lint or headphone plug tip broke off in the jack. This is not the case, I did the standard factory reset just in case it was something software related, tried different ROM's and tried cleaning the jack with air and qtips etc etc.... The last thing I tried was to disassemble the phone and completely remove the headphone jack, because I have Bluetooth headphones and I also ordered a new headphone jack online, which is on back order. The phone still shows that headphones are plugged in? Does anyone else have any suggestions on anything else I can try? I am thinking that it is a problem with the motherboard or does it need a headphone jack plugged in to operate properly?
Edit: Something else I have noticed, I have an app that toggles headphones on and off and it shows the status of the headphones. When I first boot up in the first 20-30 seconds I can remove the headphones from the jack and it shows unplugged then it will switch back to plugged. I have also attached a logcat I stopped it right after it showed that it was plugged in again. Also is it possible to just deactivate the headphone jack by making edits to the rom or would it be a kernel thing?

It has been awhile so I cannot remember where I read it but i found out in my case it was in the board. If you have swapped out the headphone jack already and it is still giving you problems then it is probably the same problem. I bought another phone with a cracked screen on eBay and swapped the board that the headphone jack plugged into.

audio jack problems

hi, i got an imate jamin and i need to replace the audio jack were the handsfree pug in, do anyone know where i can find to buy this part please or if anyone had the same problem how did you solve it.
thanks guys!!
Dodgy Audio jack
My audio jack plug works fine BUT when I unplug the headset, the phone stays in headset mode i.e. no sound from the speakers. If I plug/unplug the headset a load of times it eventually goes back to normal.
Any ideas. My solution is never to use the audio jack!

I've had two M600's which have done exactly the same thing, both replaced by Orange, I've now upgraded to an M700 and unlocked the old M600 with a PAYG sim and guess what that one has now lost speaker sound so that three with the same fault and this M600 has never had a headset plugged in.
Has anyone else had similar problems?
i had the same problem othillo before it broke so be carefull cause your is about to brake too, i mailed imate and they said the only way to fix it is to send it to them in dubai.. not relally keen to send it there .. but till today i havent find ther part any where it seems that imate dont send out parts ... as soon as i find an alternative i will post it here..
Is this problem caused by the connector itself or is it something else? If it is the connector I can buy a new one at the local hardware store and modify it a little bit to make it fit in my S200, probably going to replace it with an 3,5mm jack if that is possible...
it is caused by the connector in fact htc the original makers of the prophet on there new models they changed it to a usb connector for the handsfree i changed my connector many times with regulas 2.5mm connector but the sound doesnt work properly. what it does it comes out with out bass then when you push the talk button on the handsfree sound comes out good. another thing i noticed is if when you insert the jack plug in the connector and you pull it out a little bit the sound comes better and the talk button works, i know for fact cause i tried it that its not from the handsfee cause i tried it on another device and work properly. the actuall connector for them is different from what you find to buy even if you plug in normal 2.5mm headphone sound doesnt come out right . if you manage to make it work and modify the connector please post it here so who got the same prob like me can have an idea how to fix it... thanks
Audio Jack
Here is what the problem is:
Audio jacks have what is called a normally closed contact. Each contact point actually has 2 parts. In the closed (no headset) the 2 part of the contact point make contact (shorts). This enables the signal to pass through the jack to the phone speaker. When you insert a headset, the 2 points open (break contact) and signal only goes to the headset.
I'm talking from experience as a sound engineer for over 30 years and this is usually the problem 99% of the time when it comes to these type of jacks. One of the contacts (usually the ground when no sound or mic at all) breaks or can no longer "spring" back. I haven't opened mine yet but fully expect this to be the problem.

hi jsapper, i got what you saying and your absolutly right .. the thing i replaced mine 2 times now been done by a technician who fixes phones/pdas the thing with the connectors i replaced the device doesnt work properly sound comes out with out the bass and the talk button doesnt work .. i guess that the original part got some extra connectors or most probably the pins are switched around..
do you know if there is any special connectors for them...
I have a similar pb with my S200:
After running tomtom during 2000km installed on my motorbike w/ a 2.5mm headset, sound seems to no work anymore (neither back or ear speaker), I suppose that vibrations against jack connector are responsible.
With a bluetooth or wired headset sound works.
I have soft/hard reset, upgrade to last WM5 rom, upgrade to WM6 rom, I have tried to get in/out a 2.5mm jack connector without any result.
The ring facility is working (w/ or w/o 2.5mm jack connected), so I can say that the back speaker is working.
I am looking for a solution too...
nb: I have my back speaker + screen replaced one time after 2months.
Dean.
Have you try resolder the Connector?
it was to damaged to be resolded
Hi everybody,
I aswell have this kind of problem from time to time.My solution is quite simple.You have to use the original 2,5" jack with the 3 black "dividings".(sorry for my english) This solution reduced the problem dramatically.If the problem starts now, just plug it in and out a few times and it should work again.
Cheers
Phone Jack is a mechanical mess ...
Same prob, used the headset, rear speaker dead. I opened the prophet, unsoldered the jack and found it misconstructed.
The body of the jack is plastic and not capable to withstand the forces of a plugged in headset.
There are two integrated switches - which - when headset is unplugged are closed and deliver the signal to the speaker. one of the switches does not close anymore when the headset is unplugged. My first solution was to unsolder the jack and bridge the contacts 2 and 4 as welll as 3 and 5.
The rear speaker functions now and I can use the phone.
Next step will be to find a jack solution on the market to finally solve the problem. I will keep you informed!
thanks buzzi will be looking in here... for your post!
i had the same problem with my audio jack and i searched many forums for a solution. the only thing i can say: if you really want to use it and you want go back in normal mode after unplugging, take a little needle. if you look at the audio jack (USB is left to it) you have to stick the needle in the right side of the jack somewhere an search for a little contact (the first time hard to find, the second time easy) and try to push it a bit to the left. so the prophet goes back in normal mode. it sucks but i didnt find another solution...except for buying a bluetooth headset and use software to hear music over that (for mono headsets u can use a programm calles BTAudioToggel, but make sure u use the Toggle software, because there is another one called BTAudio, it sucks because it costs money and doesn't work for me so well)

Friends,
My prophet has exactly the same symptoms. However, I opened up the phone and carefully examined the jack. It is crap, sure, but at least on my phone it is not at fault. I tested with a continuity meter and the contact mechanism was working perfectly. Those who tried this measure without success read the following thread:
http://forum.xda-developers.com/showthread.php?t=281331
In my case it is definitely a problem with the speaker, and it seems to be eqaully common. It seems that there is more than one problem dogging the speaker of ths model.
mine's got the small contact switch problem.
it started last night! SO Annoying. Plugging a friend's original 2.5mm adapter in and out solved it temporarily. Then it went again! I have only got a 3rd party 2.5mm plug, and it took me ages to trip the small switch back with that. I have now got a BT headset on order.
Can't wait for the newer design HTC headphone adapter as I have had this problem with 5 different devices! (Tanager, Typhoon, Hurricane, Tornado and now Prophet.)
would agree with hybrid the needle trick fixed it ran media player so i could tell when it was working again. it was mentioned before that using the 2.5mm adaptor with ibky 2 rings as opposed to 3 causes this problem. I can identify with this as i have been using my dopod h/free with no problems for months i use the adaptor to plug in my headphones one time and get a eap of issues!
i will adapt a h/free to plug in some nicer headphones!
Can i use the USB connection as a handsfree port on my prophet?
Cheers
Hi, Prophet's USB is not a USB hub and thus not usable for connecting external devices - only way is bluetooth ...
thanks buzzi

Bad audio jack(?)

Is the 2.5mm jack funky for anyone else? When I have headphones or ext. speakers plugged in, slight movements will cause the connection to be lost -- I have to rotate the plug around to restore, and then hold the phone still. (Any fix other than new handset?) Thanks.
You are using the wrong size. 2.5 is too small. You should get a 3.5 and it should fit fine.
Sorry, I must be confused about the size (it's a 3.5mm jack?). I am indeed using the right sized plugs for the jack -- standard headphone/speaker plugs.

Sounds like a bad jack. Loose joints, etc can cause that. Try another headphone or speaker plug. If the same happens, you have a bad jack.

Yes, thanks -- it happens with headphones and speakers that have been fine with other devices (even happens w/the Samsung-provided set of headphones).
Bummer, but I may just have to live with it; I'd hate to trade this phone in for a refurb (for something so relatively minor)...
I had an issue where after about 30 minutes of playing music the phone would randomly think that signals were being send by whatever was plugged into the jack to pause/skip, etc. This would happen whether I was using the stock ear pieces or other headphones or had it plugged into my car's stereo.
I ended up exchanging the device to resolve the problem.
Mine has the same problem, so apparently it's not incredibly uncommon. Luckily I literally never use headphones with my phone, or anything that requires the 3.5 jack honestly so it's a non-issue.

Interesting, that happens on mine as well (I actually thought the random pausing may be a "feature" -- like for when the headphones become accidentally unplugged!).
Make sure your hedphones/speakers plug fits snuggly into the jack. I had an "issue" when I thought I had a bad jack, but I just wasn't plugging the headphones all the way in, looked like a jackass when I claimed a warranty replacement, and took the TMO skin off the phone for the last time before shipping my "defective" phone, just to try it one more time, saw that the plug didn't go all the way in, pushed it a bit harder and it clicked into place LOL

I'll admit to thinking the same lol
Thanks, that is good advice (same thing happened to me once with an ipod nano -- case prevented a plug from going in all the way!) -- but in this instance, my case doesn't cover the top edge of the phone, so the jack is free & clear...

Touchy Headphone Jack?

My headphone Jack is very touchy. They have to be plugged in and turned just right for it to use both channels correctly. Is this something others are seeing or do i have an issue? I'm using the headphones that came with my s3.
EDIT: sorry i thought i was in Q/A
I've experienced this as well but I figured my aux cable must be faulty since I had this problem on my X10.. Ordered a replacement cable, will report back once I get it.

N4 Stuck in headphones mode

Hi!
My Nexus 4 is stuck in headphones mode for a few months now. Sound on headphones is just fine. I tried cleaning 3.5mm jack, but no difference. I'm using SoundAbout app now to make phone usable, but it's anoying to manualy switch every time I plug in or out my headphones. I ordered new headphones jack from ebay for 8.95 pounds from UK (new user, can't post link)
I replaced it, but N4 is still stuck in headphones mode Before I replaced it I've done factory reset, but not yet after replacing.
Looking at the plug it seems like phone detects when headphones plug shorts two pins in connector that connects to the tip of headphones plug (pins are not shorted if connector isn't plugged in). It doesnt have a "switch" like some other connectors.
Phone was not even near water and I never dropped it on the ground.
What do you think it's wrong? Maybe damaged motherboard?

[S/W Bug or H/W Bug] Headphone jack - Earphones issue.

Moto X Style - XT1572 - India
Since last week whenever I'm plugging in earphones/headphones, the phone starts acting as though the earphones are plugged out - plugged in in a loop, like for one second it acts as though its plugged in and at the other plugged out. I tried cleaning the headphone jack with school level painting brush, tried catching if there's anything inside using toothpick and so. But that didnt solve the issue.
Next, 2 days ago, I plugged in the headphones again to check and the issue was still there. However, when I long pressed the button on the headphone, the headset icon in the status bar changed from headset with mic to headset without mic. I tried using Google Assistant by speaking to the headphone mic and it does work even when the icon is that of headset only. This solves the issue for the time until I remove the headphones again and plug them back in manually. So right now, that's the workaround which has helped me to solve this. But the button on the headphone doesnt work when I try to change tracks using it. Seems like it goes inactive after doing its work.
I'm confused if this is anything related to software or this is a hardware problem with the headphone jack. If I remember, this started happening after I updated to the August security patch. Any help regarding the same would be appreciated.
Representative Image
Edit: The headset icon with mic is now shown even when the headphones are not plugged in. This has happened earlier in mid July for 4-5 days but got solved on its own. The phone pretends as though headphones are been plugged in and thus disables media output via the speakers.
EDIT 1: Visited a service center located at Ghatkopar, Mumbai. They said it will cost minimum 3500Rs; that too without a guarantee of working n if it doesn't, I'll have to change the motherboard which will cost 15000Rs.
Did you try another headset? Sounds like the cable for the headset is shorting out or going open.

Yes I did try multi headsets. Right now the phone feels headset is being plugged in when they are not and carries out all media output accordingly. When I plug headphones with a button/mic+button, immediately, the phone opens the google assistant pop. It feels I long pressed the button on the headphones asking to open google assistant.

Gotcha... So the headphone jack in the phone needs to be replaced. Definitely a job for a service center.

Yes. And service center asked $54 to fix it. They are not sure if that will fix the issue or not.
Fix it yourself, it's not hard to disassemble this device. I replaced my battery without issues. The headphone jack is not soldered to the mainboard. Check eBay for spares.
I started having this issue recently. Looks like Headphone jack inside the phone is not working like it should. Same headset works fine on other phones and laptop, but when plugged into this x, it sounds like it is loosely connected.
anyone in NA experience this issue?

I found out that my problem is (I'm still facing it) related to the IC on motherboard and not related to the headphone jack basically. I will update the main post accordingly.

Turns out this is from lint.
I fixed my issue by cleaning out the lint that got accumulated in the headphone jack. Use the tiniest drill bit and spin it gently in the direction of drill bit curves/groves, might take few tries, but this fixed it perfectly.

I used my phone without headphone jack - physically removed from the phone for a week but still faced the issue.
I changed the jack on my moto x pure. I bought a new jack on ebay and installed it.. I STILL had the very same problem!! Just on loop connecting and disconnecting... Maybe a motherboard failure.. I will check later... but I'm just regreting the 20 bucks spent on the new jack plus shipping :'(
