My sgs2 has apparently been water damaged while skiing and now i get this weird error, whenever my earphone isnt inside the jack port it freezes. If i restart it wont boot untill the jack is inserted, only the download mode works. Recovery freezes also. I flashed to official firmware i still get the same error, i replaced the jack piece with a new one and the problem persists. It seems like a short circuit somewhere, and for some reason the earphone piece stops it from taking place. So what could the reason be if it isnt the jack piece what else could it be?? does it have a solution that can be fixed without sending it to samsung??
thx
anyone?
Anyone?
It looks like the jack acts like a bridge to complete the circuit.
I suggest you need to look at the back of the motherboard, it looks the water damage could have broken a solider path connection or sensor, normally the phone by passes the headphone jack until the circuit is complete by the metal of the headphone jack.
Other cause which neds a JTAG is that one of the instructions on the chip has been corrupted so that it can not tell the phone to by pass the jack when it does not sense it.

I took appart and took a photo of the backside, apparently there's plenty of humidity marks all around the motherboard so i really cant tell where the problem might be... if it were a corrupt instruction woould i be able to substitute the chip or is there some alternative solution?? how can i identify the problem with the jtag???
thx

Hi
The sound has stopped working on my wallaby, and I wonder if anyone can help me fix it. I have cleaned the headphone jack with a toothbrush and IPA solvent and this has made no difference. I have also checked the resistance across the contacts with a multimeter and measured zero ohms across pins 2-3 and 4-5 after cleaning.
However, I have found that the sound does work if the device is really cold. For example - if I put the wallaby in the fridge, the sound will work for a few minutes until it warms up again.
Can anyone sugest what might be the problem?
Cheers
Ben
I have also tried the playback test from the bootloader meny and this works fine.
any luck with "no sound" so far? i am having same problem with jasjar. tried to screw around with headphone jack socket like threads state but no luck. thought maybe you might have some advice on how yours is going?
Hi
No progress whatsoever. It's almost impossible to fault find without a circuit diagram / schematic. I can't get my head around why it works fine from the diagnostics menu, but not at all once I boot it up into Windows (unless I put it in the fridge).

Perhaps the failing componant is near another that emits a lot of heat when the phone is booted, but doesn't startup in diagnostic mode? Charging circuit overheating / shorting maybe? Or maybe the resistance of something in the speaker circuit is changing as it warms?
Any access to a thermal camera / image software?

just got my jasjar back after having cracked lcd and headphone jack replaced. sent to http://www.pocketpctechs.com out of california as suggested by very helpful user on this site. cost me around $20 dollars and took only a day to fix. works fine now!
more of this problem in ear peace ( audio jack ) problem ... just use some contact
hi guys, basicallynim wondering if anybody else is experiencing the issues that i am.
Essentially im ecstatically happy with my z2, except the headphone port seems faulty. While driving i use the 3.5mm jack on the z2 to connect tk the car.
This is when i noticed the faults with the headphone port. If i insert a 3 or 4 pid connector, either a 3.5-3.5 cable, a standard 3pin headphone connector, or a 4 pin headset, a slight nudge on the connector disconnects the headphones/cable and music stops. Sometimes, google now gets triggered as well. The same things happen if i twist the jack, whatever is connected. It also seems quite loose, and there is no positive click when a jack is inserted.
I would upload a video showing what happens, but my only video camera is in my z2.........
It has also not been submerged/wet at all, and is kept in a case (i tested the jack without the case as well, but it still happens)
In my brand new Z2 I also don't hear that click when inserting headphones but they are in the deep all the way. I tested 4 different earphones and speakers but none gave me any problems(I was twisting jack and trying to move it but connection was too tight), no loss of sound. I think you should get your Z2 serviced or replaced. Also I have a question. When you plug in normal headphones or speakers(not the noise cancelling ones), do you get a notification saying that you connected them or not? I only get something like this when Smart Connect is enabled...
I have issues with jack too. When you pulg in headphones, it sometimes wont recognize that something was plugged in, but if you try to twist the jack in the phone, it may get working (the sound is clear, no loss). The problem is when you put the phone in a pocket and walk, the jack is moving there so it is very likely to stop working and u have to twist it again.
When I bought the phone, I had no problems with it, but after first water test (which resulted fine, there was no water inside), the problem started.
Got the phone for 2 months and the issue still persists.
My solution is plugging in, search for the right spot before it starts worrking and walk with phone in a hand, holding the cable so it wont move in the jack.
i got it replaced in the end, had the new one for 2 weeks with no issues, so definitely a hardware fault.
Headphone jack not working after submerging in the water
Hi,
I submerged my xperia z2 last night in the swimming pool. It's been 12 hours since I submerged my phone. Every thing is running perfectly except for my headphone jack. The first time I used my earphone there's small amount of water coming out from the hole. The headphones is not working because it's not fully dried from water? I tried cleaning it up and blowing some air for some particles to get dry but it still not working.
I need help please because my phone is not insured because I bought it online
What should I do?!
So i checked dozens times if the jack socket is ok and it is, also the motherboard pads looks ok, but i can't make any headphones to work anyway.
They don't get detected, ones or twice they worked for 1 second, and then it's only rugg noise.
no idea anymore. No any garbage inside. Everything look clean and cool.
I also flashed and rooted it with 2 different roms. Didn't help.
Pls help.

hardware issue, you must need a technician
Could the IC get wrecked? It should not cause the speaker works normal. I can hear all voices and music.

Maybe the headphone jack sensor got damaged. Does the headphone icon appear on the status bar when plugged? If not, then this is likely the issue.
Where is jack sensor?? How does it looks like?

The jack it's attached to the upper part of the board. You'll have to open the phone. And it is covered in plastic. If it's damaged then you'll probably have to replace it.
With EdwinMoqs and Artas' roms volume output can be high enough to cause clipping, which is often accompanied by false headset removal event. You have to carefully adjust the maximum safe volume level, but in the end it's still louder than stock rom which is crippled by EU and probably US regulations.
I can adjust volume via headset button, with the Headset Button Controller app. Setting max volume to 80-90% should do. The clipping protection in poweramp wasn't effective, it did the job with Artas' rom.
Problem can also be caused by a switch, which should be under one of the contacts in the jack, and can be reached with a needle(i never checked how it looks inside the jack). Also the plug should fit in to the hilt. Something might block the plug, the spindle with the contacts be too short. If you get the plug fully in and still see the spindle you're safe.
Socket looks like connecting, i can see pins moving. And i was shorting some last pins and it didn't said headphones is on.
There's a new feature in Android from 5.x or 6.x up, called Pressy Mode. It does exactly what the problem is here, and it can be controlled by Headset Button Controller app.
Probably intended for using the headset as antenna for a built-in tuner solely.
Ok, thank you all to trying to help me. I fixed this, it is working for now, i don't know for how long.
I connected for couple of seconds left channel and/or right channel by wire to the grounded Metal shield on board, and it started to detect headphones every time for now. The wire is not needed for constant working. I don't know how it worked. Also, motherboard was just a little moving over socket, so it was needed to make it hold still. I puted some little plastik on board so it pressed to the back. Works for now. I just dont know for how long. But there are still some little scrathes noises so it must be faulty IC or something in way from controller to the socket. The speaker has no scratch noises, works normal. but elements looks normal no green rust or anything.
Well, all of a sudden the headphone jack won't go all the way in, which means I can't use headphones anymore. Has anyone else had the same issue or any ideas on how to fix it?
Thanks
Dude, blow some pressure air on it. Maybe is something stuck in the jack. I had the same issue on a Xperia phone. Is was a small stone stuck in the jack port.

I tried to blow pressure air on it, I tried shaking it, I took a small twig and tried "fishing" for stuff and nothing works.. Now I tried with a screwdriver and ta-dah, a little piece of fabric somehow got in there and got very compact and now it's all back to normal
I recommend toothpic for this, you won't scrach anything. Had this once. I think it happens because headphones are on top so when you slide your phone into the pocket, everything you have there can land in the port.
Hello, for a while now my phone is stuck on headphones mode and Im completly lost as I've sort of tried everything I can. the headphones logo is always on the status bar, when connecting headphones with mic, the logo changes to headphones with mic, but when pulling off the logo changes back to regular headphones. When connecting and disconnecting headphones really fast, sometimes the headphones logo disappears for a second, but them coming back again in an instant. I tried cleaning the aux port, tried opening the phone and check if all the parts are connected well, tried to completly wipe my phone and install another custom rom, nothing works. I assume that the problem is hardware and not software, but when connecting and disconnecting headphones, there's a little change, I wonder if maybe there's anything I can do.
Please help me, thanks in advancd.

If you look closely in the headphone jack, you'll find a tiny gold contact pin, which is just lined with the inner circle. Check it if it's like moved in

As far as I can see, everything is as it should be, but there contact pins all around the port, do you have any way to upload a picture of the pin you mean? Thanks.

See that shining gold pin? I'm talking about them. There must be about 2 or 3 like them. Sometimes the pins are pushed inside, which gives permanent signals of headphone connected. Getting them straight can be tough, since you have to take a really thin thing like a needle or so and then with it bend them a tad outwards.

I am not quite sure, maybe you should contact a technician. This is hardware malfunction, and nothing related to software. I had the same problem with another phone and thats what i did, but since it's tough to look in the jack of this phone, so it would be better to see a technician.
I had the same issue long back but it used to go away when i repeatedly insert and remove earphones fast for 15-20 times.. Thats the only thing worked for me
ya, i am also facing same problem that's why i change my headphone. and now its work properly, i think it's a headphone jack problem. but not all headphones work only few headphones work properly
SOLVED

I had faced the same problem, at last, I found the solution...
it isn't a software problem...
follow the instructions...
- try to clean up the jack holder with a pin or any pointed thing (mind it be care full while cleaning, be gentle)..
may this trick helps you...
just replace the headphone jack. you can get them cheap from aliexpress.com at $2 - $3, then get it changed from a mobile repair shop.
Had the same problem - cleaned the jack with a toothpick - issue resolved in no time.
