Smartphone thinks there is always something connected to 3.5mm jack. - Android Q&A, Help & Troubleshooting

So on my 3 month old Xiaomi Redmi Note 3 Pro SE is having some problems with the headphone jack. For some reason, it behaves like there are always headphones connected to it. So If I don't have anything connected and try to play a sound, no sound is coming from the speaker. If I connect headphones or a stereo to the 3.5mm jack, they output sound just fine. I downloaded a app called Soundabout which let's me force the sound through the speakers, though I have to deactivate this everytime I want to use headphones. I have cleaned my jack with compressed air, needles and cotton pads with isopropanol, but it doesn't seem to do anything. If I look into the jack it looks super clean and not very worn at all. Could there be somekind of short circuit somewhere in the phone or in the jack? I am experiencing this issue on many different roms and so it's not software related.

[Q] Make calls over external speaker when in cardock

I have the official Samsung cardock, and connected it to my car radio (the cardock has a 3.5mm jack output). Nice, now I can listen to the music on my phone over my carspeakers!
BUT:
Whenever I make or receive a call, the sound of the conversation keeps channeling through the phone's own external speaker. Disabling the phone's external speaker (either during the call or beforehand) does not fix it. It just néver get's through the 3.5mm jack output to my car stereo. Annoying, since my car is pretty loud when speeding.
[Q]How to channel the audio of a voicecall to the jack-output? Does anybody know of a fix for this? I have looked around-and-around-and-around, and have asked this before. Just can't believe I'm the only-one that is bothered by this!
I AM NOT LOOKING FOR BLUETOOTH-CARKIT-SUGGESTIONS, no matter how nice you guys mean it
Anybody any idea?
Nobody no ideas?
I would like to do this too, speeding along the motorway the phone speaker is just too quiet.

Ah, at least I'm not the only one... Now let's hope some dev is bothered by the same problem
I guess this is gonna be one of those unanswered questions...
Bump-bumptie-dum
I recon if I bump long enough, someone with the solution should notice this question sooner or later; Although I realize that moment might be somewhere around 2015, with an answer like "Buy a galaxy S9 mate..."
Anyone?
Is the S9 there yet? Or else a solution to my problem?
I have a std aux input into my car stereo. Plugging a stereo 3.5 lead from the phone jack into the stereo aux I can listen to all sounds from the phone over all car speakers including calls... Just like when a headset is connected. Calls go over car speakers and phone mic picks up voice.
It would seem then that its the official samsung dock being treated different to a simple direct lead connection.
My only gripe is during calls the phones mic works but thinks its on a std call and is a bit weak. Wish I could force the mic into speakerphone mode or the levels associated with that mode anyway. Btw... Turning on speakerphone while lead is connected stops the output over the speakers.
I have a trrs mic / stereo splitter adapter and a seperate car 3.5 mic but again the mic levels on the phone in headset mode need boosting.

Hmm... So maybe if I use a splitter to merge the signal from both the cardock AND the phonejack...
Thnx m8! Not entirely what I was looking for (one more thing to do when plugging in my phone in the car), but it just-might-work!
Will report back
Just note I do not 'need' the splitter to make it work. Without a splitter it works just fine using car speakers and the phones mic (as the aux lead is std audio lead only - not including the third ring position for the mic).
I just got the splitter to use a seperate external mic in the car. The splitter simply has all 3 rings to make phone think its a full headset connected like the set that comes in the box with the phone and splits audio and mic into 2 seperate connections. This way I then take the std aux lead from the audio split to the stereo for listening over the car speakers and use the mic split for plugging in any std 3.5 external mic.

I understood that, it's just that I would probably need a splitter in my specific situation, since all my music gets played through the cardock by default as soon as I plug in the phone... It's possible to disable this automatic switch of audiorouting when the phone get's plugged in though, but somehow it just doesn't feel right to NOT use the audio-out feature of the cardock

headphone socket doesn't activate with speakers

thanks for reading this. I searched but couldn't find anything strongly pertinent.
If listen to media, perhaps a podcast (podcast addict) or music (poweramp), then it comes out of the speaker until I plug in a headset (my old Samsung headphones work OK), and sound switches over. The headset plug has the usual tip + 3 rings.
If I plug in some external speakers, the sound doesn't cut over to the speakers on the headphone socket, so audio continues on the speaker. The speaker plug has tip + 2 rings.
My guess is that the Xperia detects the speakers from a change in impedance, rather than a switch? Or could it be the speakers's connector isn't sensed because it's only a stereo jack not stereo + mic jack?
I can't find any manual override settings in any control panel.
thanks for any ideas.

Continuing to think about this, I considered there might be an app which allows manually switching between speaker and headphone.
A bit of research and I found SoundAbout, which is far more powerful than I need as it allows you to override audio routing to any output such as bluetooth, hdmi, headphones, dock etc.

What I specifically like about this is it gives you a simple widget to toggle speaker and headset.
Of course, I'd rather the built-in switching worked, so I am still open to ideas, thanks.
Well I use some normal headphones which are standard mini jack with 2 rings and it transfers fine so I don't think it has to do with the need for 3 rings. What are the speakers out of interest?

I've had the same problem but it's not related to what I plug in, it's just random. Sometime's it's my headphones that came with the Z Ultra and sometimes it's a Monster 1/8 inch cable for plugging into my car's stereo. I think others have posted the same issue with it not detecting something plugged in. Luckily it's pretty rare for me, every month maybe.

[Q] Samsung earphones doesn't work good

Hello,
When I bought my samsung wave, I got those standard earphones with the phone. They work great, good quality, but now I have a problem.
On my wave, it works perfect. When I put the earphones to my pc, the singing volume is low and instrumental very high (cant hear singing). Same goes for the television and the S2.
What can be wrong? I mean, it works perfect on 1 device and on every other device I almost can't hear the singing, but only instruments.
Is this fixable?
ps: the earphones are clean, it is a 4 conductor 3.5mm jack pin.
It's not actually a true 3.5mm phono jack, it also has a mic connection so even though it will fit in standard headphone sockets, the connections are wrong.
They are only intended to be used with your phone.

So I should buy new headphones?
I would like to get these: CM Storm Pitch
this is also 4 conductor, but got a spitter too (to spit audio and mic)
Not sure if this wil work without spitter.
I can't understand the site but as long as they say they are android compatible and the headphones can be used without the microphone section, they should be fine.
I have some which split at the microphone from my nokia n8 and even though the connector looks identical to my samsung headphones, they simply do not work.

Headphone Sound 1-sided

To who ever can help...I'm experiencing an ongoing problem with headphones on my m8. Trying to listen to music is either one sided (left bud) or none at all. If I plug into my stereo, the Jack works and music is played normal. Coming from headphones to stereo, it goes one sided (even playing through the stereo).
I've changed ROMs with full wipe & clean install, the problem still occurs. Various headphones all do the same. I'm almost positive it's a software glitch somewhere but can't find a setting for it. I've tried freezing music apps with TB, I've also installed HK to see if that would tweak something. No clue what else to do.
To clarify, are you saying that using a line cable to connect the phone to your stereo receiver/amp plays both sides. But all headphones, it only plays on one side?
Correct...I CAN play music via aux cord but CAN"T play through headphones of any kind (I've tried three different ones).
Bump
Different headphones use different rubber moldings around the wires, especially near the plug. Some can be thicker and some have little plastic protrusions which prevent the cable from being fully plugged in. If the cable isn't fully inserted, you will sometimes receive no audio in the right ear or no audio at all. I have this problem with a pair of Sony earbuds on my S4 and my M8, and as a result, they're dedicated strictly to my laptop.
Try this...get a male to female aux cord and plug one end to the phone, then plug your headphones into that.
Also, you can try pulling back the plastic sheath around the plug and see if that helps.

I'll definitely try this out and see what happens. Its just weird because when I first got the phone the headphones worked (any and all). It wasn't untill I rooted that I started noticing an issue.
Or just cut a bit of the rubber off the edge of the headphones. With the case on my phone I had to do that for the aux jack in my car so that it would go all the way in. Of course only if they are your headphones and don't mind to do that.

How about the headset that came with the phone? This shouldn't need any jiggering to make it plug in properly.
I would also agree with the notion that if you have a case on the phone, it may interfere with the headphone plugging in. Definitely try taking the case off (if you have one on) to see if it makes any difference.
Have you tried any headphones that don't have the microphone ("normal" headsets that aren't specially intended to use with smartphones)? Its just odd that a AUX cable works, and headphones don't. The only thing I can think that can be different is the hardware and software differences that are associated with the microphone (buttons, etc.).
Are there specific lines of code I can look at in the build .prop? I've gotten half the battle covered by Uninstalling HK and fixing permissions /wiping dalvik. Again music plays perfectly through stereo, whether aux, wifi or bt. One sided when headphones are used. There has to be some funky code going on.
I know this is old but did you ever find out?

[Q] Headphones not working anymore

I got my z2 last Tuesday and my headphones (Logitech UE 350) were working perfectly until I tried using them today. For some reason they aren't being recognized anymore and the music just keeps playing through the phones speakers.
I tried plugging them into my old iphone and they work fine. I also tried plugging in another pair (Shure SE215) into both phones and they work fine. Except on the z2 it makes a clicking sound whenever I change songs now.
Does anybody know any way to fix this? Or could it be a faulty headphone jack?
Could be a number of things mate. Firstly, check and see the headphones are not physically damaged and even make sure that the microhpones in the in-ear pieces aren't affected by water exposure. Next check the headphones out by moving the wire around while they're plugged in and see how the sound comes out and if the phone reacts to any movements. When I used my phone in water even after hours of drying the headphone jack still wasn't dry so even the slightest movement switched tracks etc. Alternatively, it could be a headphone jack fault in the sense that it may be shorting? Or the 3.5mm 5pin connector on the headphones itself is damaged. It could also simply be a software glitch. Go into "Sounds" in your settings and change what kind of accessory it detects the headphones as. Try "Other", it may solve your problems. Alternatively take it into a Sony store or a phone shop and see if there's anywhere with a similar headset which you could test out.
