mic problem with my sgs2 - Galaxy S II Q&A, Help & Troubleshooting

Hi all!
I opened my SGS2 and changed new USB charger port + mic to it.
now i have problem wiht my voice call mic, it doesnt hear me.
This part i changed to new one..
Click*CLick*
voice call's works fine with speaker.
original part was: R.B43
gt-i9100 REV2.2
new part was: R.B 5.3???
gt-i9100 REV2.2
i think part is working but software doesnt detect mic...
What should i do now?
is it posible use "mic 2" the upper one.. to voice calls?

Speakerphone uses the upper mic, not the lower; that's why speakerphone works.
Either the flex cable is not attached properly, or the rubber housing over the microphone isn't seated properly, and could be blocking sound from getting to the mic.

It says its seller refurbished.It could be faulty...I dont buy stuff from Hong Kong

mic only works with phone

can anyone help with the following.....my mic will not work with any apps., ie...notes, fonix etc....but using the phone it works perfectly......so i assume that its not a hardware issue...i was using ser 1.2 when it occured, so i then flashed with a cooked rom from jeffs kitchen....but to no avail.....please..please help....its doing my head in!
I'm sorry to say that it may well be a hardware issue after all: from what we know the microphone and speaker connect to both the phone and the PDA part seperately. If you flashed a whole new ROM and still have the problem, this would tend to indicate that the unit is broken.
is it possible that the fault lies with the mic jack......?
i should also mentiom that this occured several days after getting a car kit.....and i read in a post that the connector is not to robust......

Nothing is impossible, but I would think that would cause the mic to fail for both PDA and phone. But you can try fiddling with the connectors. Try to see if there's any metallic dust at the large connector, and try gently inserting and pulling the headphone a few times.
It could also be that a surge from the carkit blew the mic-amplifier to the PDA.
Sucks...
i also noticed that in the car kit...the remote mic can be used by all apps...ie..i can record a voice note using the car kit.....so how does the car kit mic replace the local mic......

it would appear that the xda mic is permanently in car kit mode...ie there is a problem with pin 1 on the connector........if this is the case......how easy...is it to repair....if at all....whats involved....[i know this is a dificult question to answer]...and is there a way to defanitely confirm this....eg...if i try using the mic on the supplied earpiece, and it works with all apps?

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

I also have the same issue. But when i go to uncheck the box I am not allowed to do so. I see it is checked but with light green colour and i cannot uncheck it. Any suggestions?
I am not rooted.... Does this affect?
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

Low Microphone Output when connected to Car AUX?!

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] No sound from speaker + mic not working

I have had this problem for a while now.
I don't have any sound from my loud speaker in my S2, and the microphone is not working either.
I can only hear sound/use a mic when I connect an earphone (mic working is the earphones' mic).
I replaced these parts with new ones:
- earpiece speaker flex cable ribbon
- Loud Speaker Ringer Buzzer
- USB dock port flex cable (since the mic is in this part)
Nothing changed.
I'm pretty certain it is not software-related issue since I installed many roms since, and I even got back to stock, but it won't change anything.
What do you guys think? Any way I can resolve this issue?

You are not gonna like my response but its time to visit service center or mobile repair shop.
Thanks ☺
It's probably the motherboard right? Don't see much value in reparing it if this is the case since phones are getting pretty cheap today...

[Q] No speaker sound

Hi!
I have two SGP321 with original firmware, one of them is perfectly working but the other one has no speaker sound (with headphones works fine)
I have tried to put the 'no sound' main PCB on the working one but still no speaker sound so I think there is some trouble with the main PCB, anybody knows how the PCB handles this and how to fix it?
Thanks!
