So I have had issues with the head phone jack on two different thunderbolts.
When I plug in the head phones if the plug turns clockwise or counter clockwise at certain points I will lose sound from the left head phone. Same thing happens if you gently push the plug to the right.
I also tested headphones on the models verizon has on display and it did it on those too.
(note, I tried 3 different sets of head phones). This is really bothersome to me because if its in your pocket sometimes the plug gets nudged or turned).
Anyone else experience this? Not sure if I should attempt to exchange yet again.
Mine was working fine for a while but then my left side of ear buds went out. But then I plugged my ear buds into my PC. Turns out the Ear buds went bad. Skullcandy breaks way too easy...Phone is Fine though. just Coincidence I guess.

I discovered this same exact problem the other day and here's what I've found. I have 2 sets of headphones, 1 works perfectly fine and the other exhibits this same problem with the left ear going out. For the bad set, if I have them plugged in all the way then I have the problem, but if I pull it up a tiny bit after I've plugged them in it works fine. I don't know if there is a tiny difference in the length of the connectors or what but they just don't work when plugged in all the way. I figure I'll goto the hardware store and find a tiny little bushing and just put it on the headphone connector so it doesn't plug in all the way.

I also posted on the androidforums about this. Apparently it seems fairly common. I have exchanged my phone once for this issue and the new one came back the same way. I dont know if its a bad batch of phones or what. Even some of the display models did it at the store so it seems like a crap shoot.
The best thing to do would be call verizon support at this point I think and let them know its an issue so it becomes a known issue with them. They told me today that they haven't heard anything about this incident.
Same issue here. I noticed it when i had it plugged into my aux cable in my truck. Also, I don't know if its related but playing pandora over my speakers results in a really high pitched "click" from time to time. I never experience it when just my headphones are plugged in nor when i am using winamp.
I also have this problem - also the left speaker that gets cut out. I can either try to force the jack further in, pull it out a bit, or move it around until the connection is made. These are with UE TripleFi 10's.
I have the same problem.

So verizon sent me a new phone and it does not have the issue the other two phones exhibited. It seems there are a bad batch of these headphone jacks. I suggest calling Verizon and letting them know that you are having an issue if its bothering you, so they at least recognize that there are quite a few people having the issue.
If the Thunderbolt's headphone jack is anything like my other smartphones, the reason you're having problems with your headphones is because you're not using the proper kind. Look at the picture on
http://www.appleinsider.com/articles/09/02/12/macbook_owners_frustrated_by_new_audio_jacks.html
Regular earphones have 3 metal bands separated by two nonmetal strips, whereas headphones for phones oftentimes have 4 metal bands separated by three nonmetal strips. This means if you're using a three-banded headphone into a four-banded jack, the contacts don't properly align.
The reason for this is simple: the headphone jack also serves as a jack for a microphone/earpiece.
I have a special set of stereo headphones that also have a microphone so if I'm listening to music and get a call, I can answer without having to unplug.
Hope that helps.

This is not the issue as the new phone has no problem with my 3 banded head phones work just great now. There is a defect in some of the inputs. And most high quality head phones such as etymonics and shures do not have the 4 banded design.
The description you mentioned does not support the anomaly that is happening, sound does not travel through one headphone nothing gets re routed the speakers on the actual phone.
Although this is very useful post it does not explain why the head phones now work perfectly as they did on some of the other TB's at the verizon store.
I also have post on android forums about this matter.

I had the same thing happen to me. I originally purchased mine on release day, they tested it with one of theirs and it didn't do it, so they gladly exchanged it for another one.

no issue with it here
This is going to sound like an odd solution and I may catch some flack for it but here it goes: Go to the auto parts store and buy spark plug Jelly. It has the unique quality of being able to transfer electric current hence no more losing audio L or R. I did this on my D1 and it worked perfectly. Just a tip; don't use a ton less is more.

While that would help the connection, I can't say I would ever recommend it. It's going to be a dust collector, and nearly impossible to clean out. It is better suited on the spark plug because the plug is covered and sealed for most of its life.
Also, it can make a short between two of the connections, spark plugs only have one connection where the jelly goes.

Ok those are good points. What I do know from experience is that it did work on my D1 and I never seemed to have an issue with dust but that might have been because the case I used plugged the headphone jack. So.... I will repeal my suggestion; don't use spark plug jelly.

this post is wrong. im having the issues and ive been using headphones with a mic and music controls since day 1. the issue is with the jack, not with the type of headphones being used. ive tried 5 different sets of headphones and they all exhibit the same issue.

I agree with you, it should have nothing to do with having a mic, as the same exact pair of head phones I used ( 3 ring) that did not work on the older phone now work perfectly on the new phone.
SOLVED: It was the cable.
Searching around, this seems to be a common problem with a variety of phones, some it works, some don't. My old G1 worked flawlessly in this manner.
Whenever I have a pair of headphones or my auxiliary cable for my car plugged in, the internal mic doesn't work when I receive a call. This sucks, because if I'm listening to music in my car and get a call, I have to remove the phone from the window mount and unplug the cable while driving down the road, or fiddle around with the power button to switch the phone to speaker mode (screen goes black after answering a call with the cable plugged in).
Is there a solution for this other than spending $180 on a bluetooth integration kit for my car (was looking at the Parrot MKi9000 or KlaT7)? I'm a little scared of this route considering the problems people have been having with A2DP on Gingerbread. I'm hoping the official Gingerbread release (if it EVER releases) will fix the A2DP and/or this issue. I am running Froyo right now, but am eagerly anticipating the official Gingerbread release.
Thoughts?
That does not match my experience with the stock ROM. I listen to Pandora in my car via an FM transmitter that is plugged into my earphone jack, and I receive calls all the time without having to go into speakerphone mode: the caller's voice comes through the car loudspeakers, and they hear me just fine. I just ran an experiment with a pair of earphones (no microphone) plugged in and called myself from my landline and I definitely heard it loud and clear over the landline phone when I blew into the microphone hole in the bottom of the G2x.
That definitely is odd. The phone is rooted along with faux's kernel, but I have the stock ROM. When I have the cable plugged in no one hears me on the other side, and voice dialing doesn't work either. Is your G2x all stock?

Yes, completely stock and unrooted.
Have you tried it with a different cable or with plain vanilla earphones?
No I haven't tried a different one yet. I'll try that when I get home tonight. Thanks for your input!

My guess is its the cable. Probably something with the connector is tricking the phone into thinking it has a microphone built in, just like when you plug in a headset it mutes your handset mic.
You are both correct. Just tried a different cable and it works great.
The cable I was using was the one included with the T-Mobile Window Mount Kit. I was using it because I have the Speck case and the original one I bought from MonoPrice.com was too thick to fit through the hole. The T-Mobile cable was skinnier and just barely fit. I took the phone out of the case and tried the one I bought from MonoPrice and it worked perfectly.
Thanks for the help!
Now I need to decide whether or not to bore out the hole larger on a $30 case. As most reviews have stated, it does scratch very easily and is very difficult to get the phone out. Anyone know of any other cases that have a larger diameter hole for the headphone out?
Im asking all you guys to help me find best methods, settings, and tweaks to get the best possible audio recordings on my SGS4G. Im asking this not only from the devs here but from all the audiophiles as well.
The reason im starting this thread is that my partners iphone 4 just with the built in mic and camera has produced video and audio recordings 10x better then what this phone has. With great dynamic quality and no distortion or anything. I need broadcast quality recordings for this project to succeed. If i am not able to do so im either going to have to try to clone the SIM card and get a used iphone 3GS just for field work, or give up this phone and switch to an iphone 4. Either of which i really dont want to do. If part of the solution is to dump GB and go back to Froyo, then so be it.
Heres what i got:
1. Highly modded SGS4G with Valhalla 1.3.2, Launcher Pro Plus
2. 32GB class 4 Sandisk card
3. UV using the settings in the ICBINB therad (i tried some lower ones dsexton posted, but they made the phone very unstable)
4. Voodoo Plus sound app
5. i-Microphone (sound was horrible, more on this later) http://www.amazon.com/o/ASIN/B004XC6KHS/ref=nosim/betteraddons-20
6. Sennheiser E835 with XLR to 3.5 mono minijack adapter
7. Rec Forge and Hi-Q MP3 recorder (trying both, if you know of any with more features please share)
First off, im concerned that the custom ROM, kernal, and UV settings may be affecting quality. Any input on this would be appreciated. Ive tried OC, but 1.2ghz was never stable and 1.3ghz drained the battery too much.
I first off was looking for a good solution for face to face interviews, i found the i-mic (link above) to have good reviews, but when i bought it and tried it out, the recordings were horrible! Like someone was rubbing their fingers over the mic when talking. I tried gain adjustments in Voodoo and the recording apps im trying out, but nothing helped.
I plugged in my new Sennheiser using a XLR to RCA cable, with a RCA to mini jack adapter. The sound is A LOT better, but still there is a humming over the recordings, and they just do not have the dynamic quality that im hearing with the iphone recordings.
Are there any equalizer and sound processing apps for commercial or professional audio work out there?
Im at a wall here, any help to these issues would be greatly appreciated. Thanks in advance.
It's hard to tell exactly without seeing your set-up but it sounds like you have the following issue.
The XLR is a balanced connector. When you go to an RCA you are dropping down to an unbalanced connector and losing your ground. That is where the hum would stem from.
To eliminate the hum you would need a cable that converts directly from your balanced XLR to a balanced T/R/S (Tip, Ring Sleeve) mini jack. This mini jack has 3 separate contact points, separated by two plastic bands on the plug instead of one.
Ideally for broadcast quality you would need to run your Sennheiser E835 into some sort of mixer with a mic preamp. Then run the line level out from the mixer to the SGS4G. Your recordings would be crystal clear at this point.
I don't believe your issue is with the SGS4G hardware. I use the camcorder with the built in mic all the time and the audio quality is fine.
Hope this helps.
you don't need a balanced connection unless you are talking about long mic cables like over 5 feet long and equipment that is plugged into AC current. Balanced connections are for getting rid of the 60 cycle AC hum, basically.
If I was trying to record using a 4g I would think about using the usb input and some kind of analog to digital converter box. Here is a cheap one -- $25 behringer UCA 202 providing 2 RCA inputs-- it's about the size of a phone. and supposed to work on linux without drivers so maybe it will work on android. I have three of them and use them for laptops. They're pretty good at eliminating noise. I just don't know if the phone has enough power to operate the unit. You need a female to female standard usb adapter to connect the data cable to the converter and something to adapt a (short) mic cable to an RCA port. if it works you can use a dynamic mic like a AKG or Shure or some smaller dynamic mic and will get better recordings than anything built into any phone. It will be a little bit bulky but you'll still be able to fit the whole thing in your pocket. I should try it with my phone and see if it works but I need to get the female to female adapter. if the phone recognizes the UCA202 it should work just fine with a Sennheiser E835. My girlfriend uses a Sennheiser MD-431 for recording songs with her laptop and one of those units.
They also have usb mic adapters at places like guitar center. If you have the female to female USB connector you can take your 4g to guitar center or wherever and try their mics out before you buy anything.
@Nazcalito....great advice, I guess spending all my time on a control room board I hear the word 'hum' and immediately think 'where's the dirty gear, who's missing a direct box.' Haven't used a cable under 10ft in as many years. I'd be very interested to know if someone could get the USB audio/phone rig cooking on or s4g, that would be sweet.

Thanks for all the responses, ive been playing around with this and i do think the hardware is the biggest issue. I noticed the issue im having is that the built in mic is not turning off when using an external one. When using the external mic, i can tap over the back mic and get the feedback from it as well as the audio from the external mic.
Now the built in 3.5mm jack is a four contact TRRS plug, the RCA to minijack adapter is only two contacts. This would explain why the little plug in mic was getting all the feedback. Though even that mini i-mic was a TRRS plug like the headset thats included with the SGS4G. Why is the built in mic not turning off?
Nazcalito, your suggestion of the USB audio interface may work, i did consider a microphone with a USB connection, though i could not find any accounts of this working by simply plugging the mic in to the phone with a USB to microUSB adapter, and didnt want to take the chance. Though i like the converter box you showed a pic of, i could just velcro it to the back of the phone to make a mobile unit. I'll probably buy one if youre able to confirm it works. Again would i have the same issue with the internal mic not turning off when using this?
One thing i ordered was something called the headset buddy, its a TRRS male plug that splits into two separate minijacks for headphone and microphone. Im hoping this will solve the problem.
http://www.amazon.com/o/ASIN/B002SK66OY/ref=nosim/betteraddons-20
Another concern is the pinout of the SGS4G. Ive found diagrams for the i9000 that shows the mic and ground contacts swapped, and others with the regular mic as the last pin that claim they are for the Galaxy S2 and SGS4G. Anyone can confirm? This might explain the internal mic staying on.
http://pinoutsguide.com/CellularPhones-P-W/samsung_galaxy_headset_pinout.shtml
http://pinoutsguide.com/HeadsetsHeadphones/samsung_i9100_headset_pinout.shtml
As well should i have all the options in Voodoo turned on for this?
Ya know, i wish i didnt order the headset buddy already, i would have tried this:

That's not good. I have a similar problem occasionally with headphones not muting the speaker when used...I have to wiggle the plug a little until it mutes. The contacts are definitely a little touchy.

Can anyone with a stock froyo SGS4G try plugging in an external mic and see if that solves it?
I changed the digitizer on my phone and now I don't have the microphone working.
Other side can't hear me, voice recorder and voice search does not pick up anything.
Camcorder works fine and record with sound, but that I guess is separate microphone.
I searched but could not seen anyone with the same problem.
Should I just change the whole ribbon cable or there is something else I want to look at?
Thanks

its very easy to tear the flex cable containing the microphone when doing this repair. When you removed the motherboard, on the left side there were two gates, the one on top being a little larger than the one below.
this lower one is your microphone. trace it and see if you notice any rips. if not make sure the connection is solid.

I was very gentle when removing flex cables. Can't See Any damage on flex, but as you say it might be very easy to cut cable when doing repair.
Will try and flash couple of roms so hopefully have Microphone back, but I doubt it very much.
This whole flex unit together with buttons strip is quite cheap. Will probably buy it and try to chage it.
Chance Rom Did not help
I've done the same thing. Those mics are incredibly sensitive. Even of you dont see a tear, pressure on the cable can damage it. You can score a replacement for about $8 on eBay. Just make sure you buy American. You don't want to wait weeks to save 2 bucks. The vibration motor is another ***** on that phone.

Hi, today it appears that my microphone broke.
I use it regularly to dictate short messages, so I know it has been working consistently on a daily basis.
I am on Albinoman's 4.2.2 and I am certain it is no a rom issue.
I had my headphones plugged in today: I wonder if I somehow damaged the jack? I plugged in an headset (hence, with mic) and I hear the sound, but the mic is still dead (sound recorder would not move).
What is the story about replacing a digitizer? Did you do it because your mic did not work?
And in the end, were you able to fix it?
Thanks.
Hallo,
I got my new MTCD head unit. Its this one:
http://www.erisinwholesale.com/special-car-dvd/audi/erisin-es3078a-7-android-51-car-dvd-gps-dab-for-audi-a4-497.html
I have dont done much testing yet, but i want to connect my external mic first.
The HU is delivered with an small additional harness that included a external mic and a 4-pin connector on the other end. (see attached photo - connector E)
I want to cut this harness and solder a standard mic-jack onto it.
(and then desolder the internal mic)
Does anyone know the pin-out of this 4-Pin connector?!
I guess this is standard on many of the newer MTCD units?!
check with ohmeter the ohm value between gnd and signal and use similar specs mic.
Dear OP, Im very interested in you project. I have nearly the same unit but for A3. I also wanted to wait with the mic until i come up with a better solution than using the one which came with it. Do you know how to disable the standard handsfree function of the car? Now the "Mode" button always messes with the Mode of the headunit. Where is the cars' mic plugged into? How can I access this spot?
in some (i think it was russian) forum i came across the ROM wich connects via Bluetooth to the standard handsfree of the car before calling. But with the standard Rom so far i was not able to conect to it.
PS: Does your unit snap into the DIN booth like the original radio? Mine does not snap in and therefore is kinda loose
i am not sure how to measure the correct ohm value of a mic.
If i connect my multimeter to the factory ext. mic, i see 1,325 kOhm
If i connect it to my parrot mic, i see 1,660kOhm (i have attached a photo of this mic)
But anyhow, i am more interessted in the 4-pin plug, this head unit uses for the ext. mic. hook up.
As you can see on the attached photos, the lower two pins are jumpered.
And the upper two pins go to the mic.
I also found, that one of those two lower pins is a 5V supply on the head unit.
So this harness of the factory external mic seems to have some sort of switch function also...
But i am not sure, what it does...
And to answer Mighty_X´s questions:
I have no "mode" button on my head unit. Not sure, what you mean.?!
On my older MTCB unit, i just cutted the wires to the internal mic, and connected my parrot mic to the ext. mic connection.
But here, on this new Erisin MTCD, all connectors at the back of the unit are different...
regarding accuracy of fit:
The head unit didn´t fit in perfectly. Its a little bit wider at the bottom, than the original radio. If you carefully push a little harder you get it into a very good position. The cars dashboard is flexible enough for that. But thats not really a problem and its definitely not loose.

Thanks for your answer. I was refering to the Mode Button on the steering wheel.
Ahh, OK sorry
I only have the standard steering wheel without any buttons, so i can't comment on this
dont worry about 4pin conn, just check that the mic you want to use in head unit support that ohm input, otherwise the sound quality wont be good, just make "test-fail" until you get good result. just connect to 2 wires mic the mic you want to test...
But i do worry about this 4-Pin connector
If you connect the original ext.mic, the lower 2 pins are jumpered.
What internal effect would this have?
Is it just an input, that an ext. mic is connected?!
But why? Would the singals of the mic wont work without this input?
Or will this input maybe disable the internal mic?!
Then we wouldnt need to do the mod, by desolder or cut the internal mic on such units.
Thats just my thoughts, but i haven't done testing yet. Also i am not sure how i could figure it out exactly...

Well, on my unit (Erisin 3047A) the ONLY reason why the lower 2 pins are "jumpered" is purely a mechanical issue: By having 4 wires and tied them together using a cable tie the two upper (small) cables are fixed in place. So: No actual use, just for mechanical reasons.
Did you have a cable tie on your 4 wires? From your pictures I cannot see it, perhaps you removed it?
Well, I just used my external micro from the installation before, and it works great.
Kind regards,

Hi,
Ok, there were no reasons for my concerns.
I unsoldered the interal mic.
And then i soldered a headphone jack to the two wires of the original ext. mic harness.
The didnt touch the lower jumper wire.
And now:
It works great with my parrot mic! No echo, and really good quality in general! I am very happy now.
I also now installed a time-delay-relay for my rear view cam. Now the cam keeps going for apprx. 8 seconds, if i change to forward gears. Thats a great improvement also, that i can recommend

please poiint out, what headphone you used for this and the cables (by color) you connected to. (red to white for example)

Hello,
I use a PR2627 Parrot Twin Mic.
I cutted the standard ext mic and soldered a 2,5mm female jack instead of it. The white lead from the original cable goes to the "left" connection on the jack.
So the tip of the male 2,5mm pin will contact the white cable.
The black lead goes to the ground connection of the jack.
Thats it.
So, i use this Stereo mic only as a mono mic.
But it works great.
But i have to say also the original ext. mic. isnt that bad, if you disconnect the internal one.
I want to try to use the original Audi microphone. The ohmmeter says the Audi is 7,9kOhm and the mic wich came with the Erisin is 0.9kOhm. Is it possible to get good results here? What do you guys think?
I ll have to search were the wire goes wich is not to easy in Audi A3 (at least for me)
Edit: Like I thought the quality of the original mic used with the new head unit is pretty poor. dumb and very quiet. Not sure now if i get another mic, use the erisin one or maybe try a mic amplifier..
So if I understand this correct, the headunit keeps using the signal from the internal mic, even if there is an external mic connected? In essence, it gets mixed? No wonder everybody on the other end of the line is complaining that they don't understand a word I'm saying.
Is it easy to unsolder the internal mic?

You couldnt find the answer in the entire thread devoted to this issue Yes; if an an external mic input is factory, it is in parallel with the internal mic. This is a rookie design mistake.
Is there a way to change sensitivity of the external mic input? Did not find an option in the factory settings..
I unsoldered the internal mic now too. After first tests I can say say that doing that had no effect on the input sound quality or anything at all. And i found out that the internal and external mic wich came with it arethe same piece of hardware. I still wonder if there is a way to increase intensity of the mic without going over hardware amplifier. Have a kinda newer Ersisin model I guess
