Low Microphone Output when connected to Car AUX?! - Galaxy S II Q&A, Help & Troubleshooting

Hi guys,
I have had various handsets in the past two years (HTC Desire, HTC Desire HD, Nexus S and Galaxy Nexus) and I have used all those in my car hands free via the AUX socket, i.e. successfully making phone calls and playing music whilst driving
I recently got the S2 and when I connect it to the AUX in the car, music is loud and clear but when I when in a phone call the other person is struggling to hear me even with all volume levels set at max. I can hear them clearly though.
I know when the S2 was first released there was a hoohaa about poor call quality especially the microphone volume being set too low by default etc.Could this be what I am experiencing? I am in doubt because on normal calls (no AUX) the other person can hear me clearly and I can hear them.
Is there a fix for this issue? It is important for me to be able to have calls in the car.
I am completely stock I9100 ICS 4.0.3.
I have tried with and without cases without success, currently have a barely there case on.
WIll greatly appreciate any feedback

First off, you said you have an i9000, which is the Galaxy S1. Did you actually mean an i9100?
Second, it could be a hardware issue. There is rubber housing on each mic; the lower mic is used during regular voice calls. The upper is used for noise cancellation, but also it is used for the primary microphone for speaker phone mode and car mode. I had an issue with speaker phone mode where the rubber housing on the upper mic was not seated properly, so on speaker phone, my voice was muffled. I had to open the phone up and re-seat the housing on the upper mic to get it to work properly.

Sorry it was a typo, I do indeed have an I9100 aka S2 (corrected it on OP).
So the NC mic is used for car mode? The thing about the S2 is it doesnt visually show on screen when a headset/mic is connected hence I didnt think there was a car mode as such.
I may have the same issue as you, was it relatively simple to disassemble the back and relign the rubber?
Thanks

Yes, the NC mic is what picks up sound for speakerphone/car mode.
Overall, I personally found that breakdown is pretty simple. Check out this post. It details a fix for echo due to issues with the rubber housing, but it gives you an idea of what to do. Focus on the top mic; if you're not having issues with regular voice calls, don't mess with the bottom mic.
You'll need a phillips screwdriver from an eye-glasses kit, and something to pop the case apart. I used an old credit card. Be careful when popping the case apart, the power button and volume rocker can be easy to lose.
If this seems daunting to you, and you are still under warranty, just take it to an authorized Samsung repair center.

[Q] Problems with audio jack

Hi all,
to my great frustration, I've discovered that my SGS2 line-out / headphones jack seems to have a slack joint, i.e. if you turn a connected plug around its long axis, a crackling sound is heared in the speakers and at some angular positions the stereo signal will be reduced to mono (i.e. one speaker gos silent). With one device (mobile outdoor speaker) I even had no sound at all at when inserting the plug with the wrong "orientation".
Did anybody experience the same problem or am I just out of luck here?
I am wondering whether sending back the device to the retailer (Amazon) or directly to Samsung (I'm situated in Germany) will yield the faster round-trip time, any experiences here?
Thanks!
PS: I know this may be a stupid question but can somebody PLEASE tell me how to search for multiple keywords with AND logic in this forum? Tried "+word +word" and "word AND word" (without the quotes) but nothing seems to work.
Are you using the headphones that came with it? My better half went through 4 sets of the stock samsung headphones with her original Galaxy S and all produced the same issue of losing one channel after a matter of days/weeks. having the jack inserted to about 2/3rds is a workaround but not ideal as you still lose some frequencies and it's insecure... They're just a bit pony.
No, I used different kind of headphones, including Sennheiser in-ear headphones and a standard male-male audio jack connected to some bigger hifi system. With some jacks I did not encounter the problem, but most of them lost some part of the signal with some orientations: I persume that the manufacturing tolerance of the jacks also plays a role...
Anyway, it's definitely not a problem of the jacks but of the device since I tried it with the SGS2 of a friend yesterday and it worked with the same jack that made problems with my device.
I will proceed sending my phone to Samsung for repair, I hope that won't take to long *sad looking*, I am so used to it now, it's card to survive to weeks without it.
I had the same problem, all I had to do was insert headphones cable "HARDER" into the audio jack until I herd a "click" sound.
I was way to over protective of this phone when i first had it, and wanted to handle too much with care, forced the dam cable in, and "click", sounded like it snapped into place, the audio worked correctly without cracking noise or without the need to wiggle to cable get clearer sound.
Perhaps your friends SGS2 is already used to headphone being inserted, but yours not. Just add a little pressure until you hear clip into place.
If this doesnt help, then repair or return.
Thanks for the hint, but unfortunately I had the jack inserted to the very end, so this was not the problem... sent in for repair now, let's see what happens.
I have a fix for you i think!!!!!!!!
ok . when i got my s2 like 4 days ago (at&t usa version) i noticed that when i plugged into my aux cable in my car that it was low sound cracking more volume on the left side , very annoying . NOW FOR A SIMPLE FIX FOR SOME TO TRY! PLUG IT IN ALL THE WAY! i noticed when plugging it in i wasnt fully plugging it in . it should go all the way down FULLY! the sound is perfect once this is done . I HOPE THIS HELPS YOU !!!!!! good luck

Aria earpiece speaker issues - HELP!

OK, so my earpiece speaker quit working most of the time. I figured it was just a broken part, and I ordered another one. However, when the new one got here, I discovered that it required removing the screen to replace it, and also requires that tri-wing screwdriver that nobody has, so I put that job on the back burner.
Then I discovered that with the call in Speaker mode, I can hear just fine.
So, it appears the earpiece speaker is not actually broken, right? I can hear it when the phone is in speaker mode (although it's real loud... lowest volume is still louder than the loudest normal earpiece volume). So that speaker MUST be working, if I can hear it... but just not working when not in speaker mode.
In that case, does this indicate something software-fixable with the earpiece speaker?
And more on point: is there any way to force the phone to always or by default answer and make calls in speaker mode?
When the phone is in 'speaker phone' mode, the sound is coming out of the speaker on the BACK of the phone (next to the camera), not the earpiece speaker. So if you are hearing sound just fine from the speaker on the back of the phone, that would just confirm that the problem is in fact the earpiece speaker.
I've had this problem too with putting the speaker in. It took a bunch of tries to realize that you really need to make sure the speaker snaps up in there and remains tight when you put the phone back together, if it slips out a bit it wont work.
Also, it's kinda hard to figure out if you've put it in upside down, so try flipping it a couple times to see what works. Look at the dust marks for evidence of how it was originally in there.
Best of Luck!

Maybe on YOUR phone, but on MY phone, the sound is coming from BOTH the speaker on the back, AND the earpiece speaker.
I mean, I guess it is remotely possible that somehow the sound coming form the rear speaker manages to make its way to the cavity where the earpiece speaker is and sound perfect, crystal-clear, and just like the earpiece speaker should sound. I find it unlikely, but it's possible, I suppose. I don't know any way to tell.
I found an app that will put the phone in default-to-speakerphone mode (Car Mode). This works kind of ok, but the problem is that plugging in a headset doesn't override it. Of course the whole purpose of this app is to keep it from going into headset mode when you plug something into the headphone jack. I just need to have the phone simply turn on the "speakerphone" speaker when I answer or place calls in normal mode.

I agree that it's difficult to tell, but that must be what's happening. The two speakers are just half an inch apart and are only separated by a few internal components that do little to muffle sound. I don't think it's unusual that the sound would be clear when putting your ear to the front top of the phone. I definitely admit though that it's difficult to verify this -- I was trying to find an app that could play a sound directly to individual speakers one at a time but I couldn't find anything.
But, even if we assume that you're correct and the earpiece speaker works, that doesn't really leave you with many options. If it's a software issue, then you should do a Nandroid backup and then try doing a 100% clean install to see if the problem disappears or not. If it doesn't, then it must be a hardware issue. If the hardware issue isn't a matter of simply replacing the earpiece speaker, then it's not something you would be able to fix anyway.

I imagine replacing the earpiece speaker would probably fix it.
However, it's just too risky for me to have to remove the screen and digitizer in order to replace the speaker, when I have a workaround that is working.
Anyone know of a way to replace the speaker without removing the screen/digitizer?

I just bought s3 recently and have faced mic issues, its not able to pick up voice easily, have to use the other hand to cover my mouth and phone for it to be able to catch my voice!!
I am going through mic issues.
I had a mic problem with my first S3 during phone calls. I couldn't do anything about it everyone was saying they couldn't hear me.
(The sim I am using is an British UK O2 micro simcard that I used in a iphone 4, cheap samsung, and samsung S2 previously with no problems at all.)
I then returned the phone to the T-mobile shop retailers, they said it was rare and not a common fault.
My new one is doing the exact same thing, I didn't update it nor is there a new update.
Can someone please help as I am lost. Thank you.

s3 mic problem
im having same problems n im on my third 1, all with the same problems. just been through all setting n nothing, waiting to hear back from my network provider (3). good phone but really annoyed with this problem now, everything is ok i put on loud speaker but this is no use when im tryin to run a business.......
I thought I was the only one facing the issue . The handsfree using the wired headset is completely faulty and the other party can hardly hear you . However sometime it works.
I tried some options ..
1. Dont insert the wired headset in the middle of the call it wont work.
2. Insert the wired headset and then dial the number - this seems to work most of the times
3. Accepting the call while the wired headset is inserted - this seems to work.
Not sure what the solution is - anyone able to resolve it ?
not the best voice receptions by the mic....but i havent got any complaints from the receiving end...and audio recording not great but better than the s2..used both the phones for quiet long
I have same issue. Other party doesn't hear me most of the times clearly. They say that I sound like i'm using speaker mode and I'm walking in the room with bucket in my head.
I used some kind of phonecall recording app and from there I can hear myself quite clearly. Maybe it is related to service provider?
Now switched to gsm mode only to see does it make difference.

Seems like noice cancellation needs to be disabled. Worked for me :good:
Try turning noise reduction off , in the call settings section

mic problem in S3
M also having t same problem...hav done all the ways explained above...but still in trouble....sometimes mic works great but sometimes it dont...
microphooooone hole
I have a solution guys. Use left hand when phone call or grab it just for upper part. You are covering small hole for microphone.
I have like 1phone/year and never happened to me that i cover microphone hole when calling. With this one I have to stay focused to dont cover.... Its getting better but samsung engineers terribly overlooked this.
I phone like 4-5 hours per day, so i have habit to let phone just touch my hand and pretty much dont hold it at all. But when you hold it right hand your below thumb area of hand get to cover microphone hole....
and this is when someone else looses my voice over phone....
There is a microphone at the bottom and one at the top. How are you holding your phone? No matter what I do, I can't cover them up during a call.

Same here, cannot uncheck 'noise cancellation'
Wired headset only works when call made first, then audio plug inserted, even with BT disabled.
Multiple headsets mics not working that are known good headsets tested on other phones.

I have played with recording a bit lately (due to another issue of noise in audio recording) and I found that the upper microphone is disabled during a call from some reason. It is used in other video/audio recording though.

if I'm not mistaken the upper mic is working solo when ur on speaker during a call.
when u use the ear peace the buttom one is the main one and the upper one is for noise cancelation.

I only tried on speaker and the upper mic was definitely not catching anything - if I placed my hand over the bottom one, there was no sound from my side, even when I was talking directly to the upper mic.
Not sure whether it is a feature or a bug (there were some reports that the mics are switched by mistake on the software level) but if it is a feature then it is rather unfortunate one as it is quite common to hold the phone at its bottom.

You right, thats the reason for upper microphone - do compare signals from lower ant top, and eliminates noise (that coming more from top) from voice (that coming much more from low)
Other reason probably is stereo sound when making video...
PS
Comon guys, it is almost impossible to hide microphone with hand, left or right - does not matter. You should have palm from soft material as balloon to hide it Otherwise it is hardly possible by mistake, even if you try it is hard to do it

[Q] Anyone had this problem with TMO HTC One + headset?

EDIT: Moderators, please feel free to move this thread to the troubleshooting/Q&A forum. I didn't realize it might belong there... Sorry!
OK so I got a new HTC One and so far I love it in all aspects except... the following:
With a headset plugged in to the headphone jack (earbuds with in-line mic and button) any amount of jostling or rotation of the plug in the jack causes my phone to skip songs, stop playing music, and begin redialing the last call in my call log. This issue makes the phone practically unusable for listening to music, as even the slightest shaking of the plug (i.e. from phone in pocket while walking, movement of headphone cord from turning head left or right while sitting still, etc) causes problems.
I thought it was a problem with the individual device I got so T-Mobile was nice enough to send me a new HTC One...
And it has the exact same problem.
I have tried several different headsets with button and mic. Notably, all of the headsets with mic I've tried all work flawlessly on all other devices.
Has ANYONE had this problem?
Note that I Intend to record a video of the problem for evidence, but I'm pretty convinced its a design flaw in the HTC One.
At this point I have all intention to go with a different device, as much as that pains me to say (probably the Xperia Z)
EDIT2: After some experimentation, I have discovered the problem. It is a ridiculous design flaw on the part of HTC. I will post pictures later along with videos. In theory it can be remedied with a new set of headphones of a certain style or possibly some electrical tape or other insulating material, but I really don't think that should be a requirement of using the HTC One.
EDIT4: See here for my post on reddit with a description of what I believe to be the cause of this problem: http://www.reddit.com/r/htcone/comments/1k6ia1/illustration_of_a_design_flaw_with_the_htc_one/
And here is a link directly to the photo album on imgur with descriptive captions: http://imgur.com/a/uXvn3
i just picked up a set of ear bud n mic headphones today and played music and did voice commands with it today and had no issues but it was a short period of time...i will try to replicate ur issue and report back later today.
its a issue with something of htc software i believe. it was doing similar with my skullcandy ink'd second gens.
i looked into it a lil but not alot. but it seems only certain headset/earbud combos work properly. i really dont know why theyd have it like that. but for me i had to play around with the mic button and what not.
It's the head set I have earbuds and soul, soul works fine

I've run into this problem on other phones before, but it was always the 3.5mm jack. Either it was tarnished or the case/jack design combo was causing it to not seat fully. Check very closely that the jack is fully seated and maybe try with another set before condemning the jack in the phone as bad.
I believe I have diagnosed the cause of this and other problems. Please see the OP for links to photo album with descriptions.
I purchased mine back in june and never had this problem. Ive used 2 pairs of headphones with the device (some $5 kyocera promo headset from when I worked at metropcs and a pair of Sony MDR-XB500). Only thing I could think of would be faulty software/hardware (phone jack) combination.

yeah , it's right.
I have this very issue on my HTC one Since my wife's HTC one doesn't experience it with the same headphones I just concluded it was some tolerances that were off on mine I mainly use Bluetooth so I didn't feel it was a big enough issue to return. I had originally searched to see if it was a widespread issue, but could not find any others who had it.
I have not had the problem, either with a headset or an AUX cable I use for my car stereo. The headset jack on mine fits very snug and the plug does not touch the housing except maybe a very small area where the lip is metal.

External speaker bad contacts

I dont have sound unless i press on my speaker, and i ve been reading forums and people say my pins on my speaker need to be lifted, i lift them and i still have the same problem. Is there any way to improve the contact of the pins and the speaker to have my sound working without having to apply pressure to the phone's speaker?
Put a piece of paper next to the speaker, pressed it with the back cover and sound works now, for those who have similar problem
