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.

[Q] 3.5 Headphone Jack Issues

Hi guys!
I searched around for this problem, but couldn't find a good answer. I am using my Desire HD with the Klipsch Image S4 IEMs (great headphones!) and recently I have this very annoying issue.
Most times when I plug the headphones in they get recognized as a headset (with microphone and buttons) and the slightest movement causes the music player to start playing or change or song, or what's even worse, the phone to redial the last call.
At first I thought the headphone jack had gone busted so I tried with my full sized Beyerdynamic DT770 PRO cans, but I get the same issue. When I use the stock headset that came with the HD however, there's no problem.
I think what's happening is that the 3 part plug (as opposed to the 4 part of the stock headset) doesn't always make good contact, or it touches the connector for the 4th part briefly at insertion, and it creates this problem.
Does anyone else have this issue? Is it possible that the plug on the phone is busted? I don't feel like sending the phone in over such small thing, but it is pretty annoying...
Thanks!

I have the same IEMs as you do, and I have not noticed that problem. I had similar issues with my Xperia, cleaning the 3.5 mm female connector helped for a while, but I eventually had to send my phone back to be repaired.

Seen the same thing when using my external speakers, something goes funny with the resistance or capacitance.
Difficult to test unless you sacrifice the cable
Try cover the 3rd and 4th section with nail polish or some other non-conductive stuff.
Ideas? Maybe lookup the schematics of the jack and confirm contact areas, then fix up as needed.

I can easily get a 3 and 4 section jacks and cables on the cheap for testing purposes. Do you have an idea of how to go about testing it in some systematic fashion? I wouldn't mind cutting the cable of the headphones and soldering my own jack at the end of it if I am sure that it will work reliably.

Try measure the lengths accurately from the headset included with the DHD.
There might just be some overlapping. If that is not the case, it might be a bit problematic.

There's no overlapping, but the tip of the S4s is a tiny bit shorter and a bit thinner at the base of the last, topmost, part. Weirdly enough I just cleaned the tip a bit and that seems to have solved the problem for the time being...
Maybe the dirt was leading to some resistance? Do you know how the buttons work?

HTC earphones stops working after using them for a while!

My HTC earphones won't output audio to my left plug.
This is the third pair I've gone through as all the previous earphones had the same fault. And it's always the left plug that stops working.
Are the HTC branded earphones really that bad?! I'm going to buy myself some quality earphones than wait once again a week to get another pair of soon to be faulty earphones.
Has this happened to someone else?

I would be inclined to think that this is connector problem, not the ear plugs. I have used the original plugs for just over a year with no problems whatsoever.
Sent from the bottom of my underpants

Just tested a bunch of other earphones, all of them work.
Something is wrong with the plugs because they work sometimes if held in a special way. My father pointed out that it could be a fault that occurs while the phone is in the pocket. However I never put my phone in my pocket while listening to music.

I don't think it will be the phones, try some pure alcohol or similar cleaning fluid on earbud jack and phone socket

Interesting, I had the exact same thing. I just ordered a new pair off amazon about 3 weeks ago. They were working perfect one day then the next time I went to use them the left one didn't make the slightest sound at all

Static noise when headphones are plugged-in

Hello,
So I have my Zenfone 2 since some months now and since the start, my phone has a problem:
When I plug earphones or headphones, there's a static noise on the left earphone (or on the left side of the headphone).
I contacted Asus, they told me to update my firmware, which I did (I even updated to MM today), but it didn't fix the issue. So they told me to RMA it.
I'm just posting this to know if someone here got the same problem and if he fixed it. I saw a post on a forum which said to deactivate every single sound (notification, etc) and only activate multimedia sounds. For some reason, it worked, and I didn't ear the static noise again but some days later. I tried to do this operation again but it doesn't seem to work.
Thanks for your help,
Best regards,

Have you tried cleaning your jack input?

I thought of that but I don't really know how to do to be honest, I don't wanna break anything. How should I do it? Should I wet the tip of a cotton swab and "polish" the jack input?
Thanks for your reply!

Usually i dont use liquids on my phone. Get a pin and a light source. First look inside of the jack if there is some dust or cotton thingys take out with pin

Hello!
I tried to see if there was some dust in it but couldn't find anything. I, however, used the pin but the problem still persists
I noticed that when I was plugging in my earphone, if I plug in "at the middle" of the jack, there will be sound on the left earphone but not on the right. If I plug it in completely (when you hear the "click" sound), then there'll be sound on the right but not on the left earphone, like I first said on the first post. Maybe this can help you.. I'd like to not send it but if I really have to, I will ._.
Thanks for your help.

Have you tried another headphones?

Yeah, I've tried 3 different headphones but the problem still persists.

You can clean it with a compressed air can, the kind that is used to clean computers. I have one at home to clean my keyboard from tieme to time and have also used it to clean the headphone jack, since it doesn't use any liquid. You can get one at the local computer store or online from Amazon and similar sites

Hello,
Fortunately, I had a compressed air can at home. I tried to clean it with that but the problem is still here
Thanks for your help though, I really appreciate it.

So I "resolved" my problem.
Since I think my jack is broken, I bought this on Amazon. So I did a little setup so I can properly hear music/sounds:
I have a Logitech G430. When I want to listen to music on my phone, I plug my earphones on the G430 adapter, then I plug the USB cable into the USB-microUSB adapter I just bought, and I plug the microUSB cable to my phone. And it works perfectly!
Some may say It's a pretty rough setup, but for me, as long as it works, that's perfect.
Thanks for your help!

I'm sure a pair of cheap BT headphones is cheaper than that setup. Anyway, if you want to keep using your 3.5mm headphones (I would since mine are very nice and were expensive) you can also try a 3.5 to BT adapter, which is also a cheap and nice option. Music through BT is usually of less quality than through the audio jack, but it¡s better than nothing and you don't need so many cables.
Something like this: https://www.amazon.com/dp/B00UUDZSKE
That one is $19, but you can probably get a cheaper one from a Chinese store such as Dealextreme, GearBest, etc. I have one which I got on eBay years ago and I think it was worth something around €10

Speaker issue after screen replacement

Hello, I have replaced the screen and housing on my LG Nexus 5x which went OK.
However, I now have no audio from the loud speaker under certain situations. I have replaced the earpiece (I now don't think this was anything to do with it) and headphone jack to no avail but have narrowed it down to the lower back plate (the bit you screw in over the headphone jack). Sounds through the headphones work correctly BTW.
When the back is pressed on very lightly the speaker works. (so the pogo pins connect to the cover/speaker). However, when you click the plastic on speaker cuts out. My guess is something gets pushed in too far so something either loses contact or makes contact that shouldn't.
Any thoughts/ideas most welcome. I've made a little video to illustrate what I mean: drive.google dot com /file/d/1CU37Fvrq2NfL6WKNS0sn0ssw_3s-BWx1/view

same here after battery replacement
Although i have purchased a new speaker still no sound out of it.
pressing the back did not work on either part.
any suggestions?
