Problem: Stuck in headphone mode after using 3.5mm audio jack

I was listening to music in my car today with my Sprint TP2 hooked up via the 3.5mm audio jack. When I disconnected the phone from the jack, the phone remained in 'headphone mode'. I knew it was in headphone mode still because it displays the little headphone icon on top and I could not hear any audio unless I reconnected the 3.5mm jack. So basically, I can't call anybody from my phone right now unless I hook it up to some speakers via the 3.5mm jack. That or use my BT headset.
Things I have tried to fix the phone;
- Unplugged and replugged in the 3.5mm stereo jack numerous times.*
- Soft reset
- Removed battery for 30 seconds and restarted
- Connected BlueTooth stereo headset and disconnected
* Extra weirdness; Gives me a voice commander error when I reconnect the jack. Voice Commander is not even enabled.
Nothing worked. So I just did a backup of my phone and I'm going to attempt a hard reset. We'll see if that fixes it.

Update: Right after I posted this thread, I tried plugging in several different devices with 3.5mm jacks and the headphone icon disappeared. However, I still did not have any audio. So I did a soft reset and surprise surprise... audio is back!!!
Anybody else encounter this bug? I'm not sure if it's a software or hardware bug, but it's definitely a bug.

guys, do you mean you have already have the 3.5mm specification tp2 ?
i didn't see it yet..

sounds like a hardware issue? especially if the soft reset did not resolve the issue...

Sprint and Verizon versions of TP2 have a integrated 3.5mm jack.

I just had the same problem being stuck in headset mode
I tried a soft reset with no luck so I was pretty sure it was something physically wrong. Instead of plugging my headset all the way back in and taking it out, I used the tip of the plug (like a Q-tip, 1/4 of the way in) to see if there were any sensors or metal still depressed and after a few light sweeps, the headset mode icon disappeared. Keeping my fingers crossed, I didn't use the 3.5mm jack for the rest of the night and I was able to use my headset and removed it without a problem this morning.
Ultimately this is most likely a physical issue, but I'd rather not send my phone in for a replacement (even though this would probably qualify as a manufacturer defect). Hope this helps if anyone experiences this in the future.

It is a hardware issue and is common to most 3.5mm jacks. I had also experienced this last year with my Treo Pro and since I really wanted to know the problem, I opened up my phone and voided all warranties. Inside the 3.5mm jack there's a lever type copper that bends to make contact with another copper metal, some kind of switch that's supposed to connect and disconnect the contact between these 2 metal pieces whenever a head 3.5mm plug is inserted.
What happened is when you disconnected the plug, the metal that's supposed to bend back to it's original position never did. That's why it's permanently stucked in headset mode because the phone thinks the plug is still inside. This probably happens due to age and possibly has something to do with moisture and rust, not to mention that copper is highly malleable.
Sad to say that until now this technology hasn't changed and is still being widely used. Hopefully someone will give this issue a real solution.

I had this problem recently and took a dry q tip and rubbed it back and forth across the little pin on the bottom of the headphone jack until it cleared up the problem.
Does anyone know if a USB to 3.5mm headphone jack adapter works on the CDMA tp2? I'd really like to use regular headphones but don't want to jeopardize getting my phone stuck in headphone mode.

Yes, the USB headphone adapter works on the CDMA versions. If you plug in a second headphone set to the other open port, which ever one was connected lastly will be the one to have sound.

Fixed the problem!
I had to disassemble the phone, voiding the already expired warranty and solder the contacts together on the audio jack. I can't use a 3.5 mm jack anymore, but I can at least use the phone now without always using a bluetooth. I'll get a usb adapter for when I want to listen to music.
Here is a picture of the contacts I soldered. I used a 20 w soldering iron, I wouldn't use anything larger.

Jack problem

On my WFS jack connector jumps out about 1mm... it is big problem because it stop playing music. WHY? Does somebody have same problem?
Sent from my Wildfire S (root, cwm..)

i used to get this ALOT if i just use my standard headphones directly into the socket. even if it doesn't "pop out", the slightest movement of the headphone jack would cause it to "disconnect" and stop playing music.....VERY annoying.
I managed to "fix" it by simply buying, a cheap as chips headset adapter on amazon. I have no idea why this works, as the plug on the end looks identicle to the one on my headphones, but for some reason, if i use my headphones i get disconnects.....if i use the wired headset adapter then plug my headphones into that it works. no more disconnects.
like i said, no idea WHY this is the case, but it worked for me. i juse bought the cheapest one i could find, i think it was around £2 on amazon.

if your using the original headset, i would do as stated above or:
go back to the shop and ask a refund or repair.
if your using your own headphones:
try using your headphones in other devices (pc, mp3 player) and see if it does the same, if not contact the company where you bought your wfs if you still have warrenty, i would not accept this kind of hardware failure.
good luck with your headphones

GLORIS:
Well, i have Razer Electra headphones... it have support for HTC (mic on wire, 4-pin jack)
JACK ON BOTH, ELECTRA AND ORIGINAL HTC EARPHONES ARE SAME SIZE!!!
my theory: magnetic??? your jack from amazon is magnetic, check this now please
VitanyLTD:
phone is ok, original earphones from HTC connect perfect but others not.
YEP! HTC earphone JACK CONNECTOR IS MAGNETIC, SO WE NEED MAGNETIC 4-pin JACK CONNECTORS!!!!
best will be reduction JACK MALE 4pin to JACK FEMALE 4pin
AFTER THIS I HATE HTC FOR HARDWARE SUPPORT!

Looks my orginal htc headset is not orginal or something cus same thing happening to me.

that's a negative on the magnetism front :s

as I sayd... and headset adapter is magnetic?

no, neither the headset nor the headphones are magnetic. I can genuinely see absolutely no difference between the two plugs, but one works, one doesn't :s

then i don't know.

I to have problems with 3.5mm in car its loose any slight movement will turn off music. i will find an adapter to.

I need JACK 3.5mm 4pin reduction for my headphones.. On cable I have mic...
can somebody find it JACK 3.5mm 4pin male to JACK 3.5mm 4pin female? I can't find anything...

just ordered this. according to the listing there are 3 in the pack, and that's only around £2.70. So if it works out well, and anyone in the uk wants one I should have 2 spare when they arrive, just let me know if you want one and you can have it. I'll try it out first when they get here though. From the description, it sounds like it takes the 3.5mm 4 pin (with headset) and converts it to 3.5mm 3 pin (normal headphones). So it should be perfect if you don't want use of a mic/headset.
My headset cable adapter works well to be fair, but the extra cable does make thigns a bit unmanageable, so hopefully this adapter will work out a bit better

I had the same problem. After trying different headphones, I decided to take a small slotted screw driver.
Just stick it into the slot and turn it a few times without too heavy pressure and now everything works nice!

LOL, you should be a doctor... a surgeon man ... just stick your knife in a man without too much pressure, and it works out perfectly ... lol ... or maybe a butcher better

Haha...yeah, that's how I deal with my problems xD
No seriously, I was really worried before I did it but it worked out fine!

those plugs for headphones 'felt' cheap the first time i plugged my headphones... they rly have little something that stops you from plugging propperly so you just roll it few times, i did it with my hp-s...just roll and push a bit... and i smiled just how u did it with screwdriver xD
but the main thing is, that it works... you guys decide: screwdriver or headphones jack xD
Sent from my HTC Wildfire using xda premium

I personally would go for a screwdriver and a hammer...
EDIT: I had that problem with a pair of Creative EP630 in-ear headphones (cheap eBay copy).
Since I bought my Sony MDREX-50LP (guaranteed original) never had that issue.
The sound with Poweramp is absolutely FANTASTIC.

Was so Angry when I first found this problam, I listen to a lot of music. I twisted the Headphone jack a couple of times and Voila!
Thank you Wfbml + b02!
Now I can enjoy my SteelSeries Siberia V2's as well as my Hi-Fi on my WFS!
Yes, I do have the Beats "Mod" Installed.

YES!!!
Sorry for digging up an old topic but I just had to say thank you so much for the screw driver fix : it worked like a charm and I can finally make use of my music again!

Dude thanks for digging it up, I've been having the same problem and now its fixed. This should be in the FAQ

[Q] Fried Headphone Driver?

So I am having a weird issue with my headphone jack. I have replaced it to no avail.
One day it just started getting all static-y and then cut out in a period of 10 seconds or so. If I wiggle the headphone jack it will come back on. However, without even touching the device, it cuts back out sometimes.
I have tried flashing different ROMS so I know its not software related.
I had not played with any audio software that boosts gain that could have damaged it that way.
As I previously stated, I ordered a replacement jack and replaced it, making sure the ZIF connector is snug and making contact.
It does it with anything plugged into my headphone jack, any pair of headphones, any stereo with a 3.5mm to RCA cable, anything.
Has anyone experienced this? I have a feeling whatever circuitry that drives the headphone jack itself is damaged.
Audio is always fine over the speaker or bluetooth.
Thanks in advance.

It's a common issue with these phones. I went through the same thing you did, ended up replacing the jack multiple times to no avail. Eventually just cashed in on my phone insurance and had them send me a new one. As far as I could find, no one was able to resolve the issue once it began happening, but it would gradually get worse.
Sorry to be the bearer of bad news, but I'd hate for you to chase your tail around as I did. Temporary fix is putting pressure from the front of the phone to the back in a pinch fashion about where the headphone jack is. Goodluck!

Try using a hair dryer on it for a few minutes (medium to no heat with a fast sweeping motion... not concentrating the air on it 100% of the time). There may be some moisture in the connection that might be messing with it (happened a few times with my portable devices and it helped all the time).

I have fixed tons of these on our phones. Common issue. That part is like 5 bucks the you need to replace. Taking the phone apart to do so, its pretty simple. on a scale of 1-10 10 being hardest i give it a 3. I can assure you wont void warranty because there's nothing to void, lol. If you need help advice or want me to do it for ya, send me a message.

What is the part you are referring too? I have already replaced The headphone jack and it did not fix it.

If you replaced the internal jack. Then 1 you ordered a defective one or 2 your main board is fried. If you bought the part from China its probably bad. Edit: did you actually replace the headphones yet?

I ordered it from a US seller. And yes the headphones were the first thing I replaced. The headphone circuitry must be fried. Oh well. Thanks for the help guys.

Did you clean the area with 99% alcohol?

Headphones easily pull out of Audio jack

My headphones pull out of my audio jack very easily, too easily. I also tried cleaning out my audio jack too, but it didn't help very much. Any suggestions on what to do about this problem. Anybody else experiencing this?

Are you using a case or does it also happen when you don't use one?

It happens even when I don't use one.

This happened to me too quite recently, was really bummed since the phone was going really well for almost 2yrs, turns out it was just lint from my pocket building up in the jack and getting mashed in by the 3.5mm plug. Got a toothpick and pulled it out in a clump, hasn`t missed a beat since. Of course the other problem could be the headphones themselves, try to replicate the issue with another set if you can and if they`re an expensive headphone you can re-terminate them or have an electronics store do it for you!

Type C Port somewhat broken ?

Hello Mi6 Owners
Im quite happy with my Mi6, but ive noticed something which is very bad.. Since Mi6 doesnt have a headphone jack it ships with an adapter.. Well I've lost that original adapter, and then a few days after i lost it ordered an replacement.. That replacememt worked for a few days, but the cable on that one was pretty flimsy, so it kinda broke amd i returned it.. Then i ordered some nice looking cable, and i plug it in, and it doesnt work at all, no headphones recognized and no sound coming from them.. So i thought the cable was trash and i bought one from a quite known brand where i live, in a local store here, and again it doesnt get recognized.. But i noticed (Note that all cabled i ordered said, they were compatible with the Mi6) that when i plug the headphones in the plugged in adapter, i get some weird noises, like when you rotate a 3.5mm jack in its port, some weird sounding noises, but thats all noise i get out of it... So is my port broken ? Charging works completely fine.

That's a weird one.
Hopefully its not broken as it seems to be okay with everything else.
I have no expertise on this but I have two suggestions that won't hurt you.
1.a. If the phone isn't playing music from the speaker then it has detected the headphones. It sounds stupid but on MIUI if you put the phone on silent the volume of music goes to 0.
Double check you have turned the volume up a bit and not on 0.
That's the kind of thing I would make a mistake about....
1. Use something very thin and very gentle (don't scratch anything) to clean out the port. It could be a piece of dust or something.
2. Does the port work for data transfer to a PC? If so then the data pins of the port are working.
3. See if you can borrow someone's adapters. But remember different manufacturers switch around the pins inside the phone and adapter to make only their adapter work on their phones. Its actually really awful they can do this as the whole point of USB C is to standardise everything....
Mine however works with the google pixel adapter so some of them will work

Hello, thanks for your reply
1. Its not getting detected.. So i plug them in, the sound goes through the speaker, as if no heaphones are connected.. The only sound i get from the headphones is when i twist them around in the adapter, a bit, like some weird noises, but definetely not from the music playing (but the adapters ive boight clearly say they are for Mi6)
2. Data Transfer works without problems.. Pc detects it and can copy files in both ways no problem

Those USB-C to 3.5 are a NIGHTMARE, mine was acting like the one you have... if you headset has a detachable 3.5. You can buy a usb-c to 3.5 so you avoid any adapter..... But in the end is cheaper just to get some cheap BT headset. Jbl, Phillips among other sell BT headset for not a lot of money.

Hello, i own a xiaomi mi6, but my model was with main MIC damaged so i have replaced It. Now main MIC works fine and charge working too. The only thing that does not work is the audio output of headphones. Can someone help me please?
