Top Side Microphone

I had to replace my s4 and the one I got has issues with the speaker phone microphone, the one on top. I can't find anything about how to replace it, if possible. Does anyone have a source for that or experience doing it?

Looks pretty easy & you can get the assembly fairly cheap...and looks like it's attached to/with the charging port http://www.amazon.com/ePartSolution-Samsung-SPH-L720-Charging-Microphone-Replacement/dp/B00EZ69E34
Here's a vid for the charging port replacement (since mics are part of that assembly)

Is this for the mic at the bottom of the phone near the microUSB port? I'm having issues with the mic at the top near the audio jack.

Yep, I did notice you initially mentioned the mic at the to of the phone, which is why I posted what I did.
I personally don't have a need to open my phone up to see for myself at this time, but if I did I'd chronicle the process for you and share some pics.... but again, in the links I shared, pics and vid are relatively easy to follow and access those particular parts for you to see what you actually need.
That said, the assembly for the link I shared looks like it includes the ribbon for the top mic as well as the bottom mic.
Also, from the links that I shared, the teardown only shows the mic location at the bottom, which would be on the assembly. The other mic isn't necessarily shown. So, I think you'll need to do some homework and see how the tear down is. It looks relatively easy to get to, so you can see where the mic is/how it sets for the top...or if it is like the mic at the bottom.
These are what would appear to be the bottom mic http://www.ebay.com/itm/2-x-Replacement-Internal-MIC-Microphone-for-Samsung-Galaxy-S2-S3-S4-I9300-/261421772171?pt=US_Cell_Phone_Replacement_Parts_Tools&hash=item3cddf3ad8b
So, it isn't necessarily clear if the top mic is the same or not - that's where the links are for, so you can take a look at what you'll need. Crack that puppy open and take a look.
The other thing I was thinking is that it is so close to the headphone jack, it might be a part of that assembly, which is also viewable in the teardown pics. http://www.ebay.com/itm/OEM-SAMSUNG-GALAXY-S4-SPRINT-SPH-L720-REPLACEMENT-AUDIO-JACK-HEADPHONE-PLUG-/141236749614?pt=US_Cell_Phone_Replacement_Parts_Tools&hash=item20e25dc52e
It's hard to tell what it is exactly without seeing it upfront, so I'm just trying to help point you in the right direction...but I suspect you'll have a better idea if you can take a look on the inside. And judging from the previous links I shared, it doesn't appear that difficult to access where the top mic would rest to see what you need.
EDIT: one other thing, have you simply tried pushing the tip of a push pin or needle to possible clear any debris out of the hole for the mic? is the mic just not working at all? How do you know it's the top mic?

Excellent, thanks. I'm told it's intermittent when I'm speaking on speakerphone (top mic), but not on the regular headset (bottom mic) or bluetooth.

Just curious, but have you tried turning off the noise cancelling/reduction option? it might be trying to adjust with background noise and is actually working against you...
you can get that from the dialer > Menu > call settings > and deselect "Noise Reduction" ...or during a call hit the little sound wave icon that has a line diagonal through it... it is directly above the "Add call" button - so that it's "grey" rather than green.
Sounds more to me like the noise reduction. Just a thought.

That might be it. I'm on AOSP, but I turned off the noise suppression.

Well, you might be able to narrow it down at least to software or hardware for sure by trying a different ROM and see if it persists...

Microphone not working on Galaxy S5

My microphone on my S5 is not working. When I make a call I can hear the person but they can not hear me I also tried recording my voice and it didn't work, so clearly I am assuming the microphone is broken. What part do I specifically need in order to replace the microphone and have it working?

Sounds like you didn't do a search and read the existing threads on this subject. Your assumption that the mic isn't working may not be correct. You should at least try turning off the noise cancelling settings first, speaking closer to the mic, et cetera. There is also a service menu setting for microphone gain. Failing all of those items, then a warranty claim or buying the part yourself, if out of warranty.
All of these are elaborated in more detail in existing threads.

I have tried everything you have said before. If I could possibly know what specific part that is faulty so I can replace it because the warranty is expired

It would have been helpful if you had bothered to tell us up front that you had done so.
The primary microphone is part of the charging port assembly.

Ok so replacing that part should fix the problem?

I was having mic problems. Remembered a friend having issues on his S3, he used a needle to clean rubbish out of the hole on bottom of the phone. So i did the same, very thin needle only pushed in a small amount, pulled a load of fluff out. Problem solved. Two mics on s5, bottom is for using phone normally, top is for when you use in speaker mode.
Might be worth a try.

Is your phone rooted?
If yes than are you using custom kernel?
If Yes than which kernel?
Sometimes it is due to kernel.

Such problems are more s 5 s
This is probably due to the waterproof cover

I have a rooted stock G 900 a mic doesn't work but speaker does. left touch button doesn't work or light up. the device is still under warranty so we sent it back to Samsung and they wanted almost $200 to fix it whereas I am going to pay $10 for that whole board and microphone I'm fix it myself I am hoping that this will fix the problems. I am 99% sure it is because of some water damage. just a small amount of water I believe got in the charger port. check out what. I will update on this too with results. maybe a video. I have replaced glass and motherboards on many s5 but this is a really advanced repair

Seems like my S5 is doing the same thing. It started doing this just in the last few weeks, and I haven't figured out how to address the problem.
I am having the same issue as navpal above
Does anyone have any idea how to fix this frustrating problem?

I also would appreciate if solution were posted. HEre are things I have tried with no success.
I cannot even slightly be heard on other line, except when in speakerphone mode. I can hear myself on my side, so I know that the sound is being recorded by at least one microphone.
tried:
clearing system cache
factory reset
clearing out microphone with pin

Hi there.
I have (not mine) Samsung S5 in my hands
Have tried:
Safe mode
battery out of the device and back on method
cannot do factory reset - still don`t want to disturb the client about that
Can you give me picture only of the MIC,not the whole board and others?
Maybe i can try clean it.
If i try to replace the old one will that be enough for me - i attach one photo ?
How is that done at all?
Thanks in advance

Hey Guys,
Im having the same issue. My phone went underwater without the USB flap cover and now the microphone does not work.
Should I replace all USB board? or replacing only the microphone piece would solve the problem?
Also, I wasn`t able to find more threats about it, if you guys have it, please help posting here the link.
Thx

You're about a smartass aren't you

This is an old thread, but I wanted to share my solution to this. My mic audio was very weak in speakerphone mode on Galaxy S5, but was OK in normal phone mode. The S5 has 2 microphones: bottom one is for normal mode, only top one is used in speakerphone mode. On mine the top mic hole was internally plugged with some debris. After cleaning it out by carefully inserting a broken-in-half toothpick (the blunt end) and twirling it while holding phone upside down to allow dirt to fall out, my speakerphone mic audio problem has been solved. If your mic audio is OK in speakerphone but weak in normal mode, it could be the mic hole along the bottom edge that needs cleaning. Using Voice Recorder in INTERVIEWEE mode will test only the upper microphone. Other modes of Voice Recorder enable both microphones so would be less conclusive. Cleanining out the mic holes completely solved my problem, while software fixes such as unchecking noise cancellation did not make any significant difference. Hope this is helpful.

My friend you saved me.!!!! i have tried a lot of things but the cover was the problem. Without it the mic in speakermode works great now.... I think even Samsung cannot explain this.!!!

Help identifying the little hole next to sim card tray

Hey,
I was swapping out my sim card and not paying attention - I accidentally pressed my sim opener into the other little hole that is near the sim card opening hole.
As it didnt open and I wasnt looking I naturally pressed harder, then i looked and realized I am pressing in the wrong hole!
Bit worried I might have damaged something, I hope this hole is not for mic or anything, I have googled but I cannot find out what this hole is for.
The hole in question is the one to the right of the sim card tray, there is only one other hole on the top of the bezel and this is the one I pushed into

Yes but when I activate speaker in-call, only top mic reives my voice. That means not for only cancellation. Hope hasnt damaged it..

Skyhigh too, if you have seconday device near you or someone's, call and check if you wonder, never mind..

I tested the top mic.
The scenario is when a call is active:
- when normal speaker is on the top mic does nothing and the bottom mic receives sound.
- when loudspeaker is on the top mic picks up sound and the bottom mic turns off
Try is, make a call to another phone, play some music or something into the the top and bottom mic's, you will notice that the top mic only receives the sound when the galaxy has its loudspeaker on - also, when the loudspeaker is on the bottom mic doesnt receive any sound.

ps, luckily there is no damage to it.
I have 2 edge+ and I tried the one I pressed into by accident, then immediately after I tried the other one.
The sound on the other end of the phone is the same. Means the little mic at the top is pretty strong, must have a mesh gauze or something protecting it?
Anyone have a pic of the internal part>

Yup, thats what I said. Glad to know its not damaged.

I realize this is an old thread. But I just did the same thing with my note 8. OP did you ever run into issues after you did this?

OMG. I just did the same thing. On an old note 5.

I did this on edge plus but thought that was IR sensor, googled but no info to find and finally here...I hope it is not damaged & even if, much relaxed to know it is secondary in a sense, and does not harm the functioning...

Sound

Strange, when i make a call, I can hear the person on the other side, but they can't hear me.
When i use intercom speaker it works, they can hear me and also when i use my headphone.
nothing strange with sound setup. I even did a reset still the same. Please help.
I'm on original stock firmware. No root or unlock.

Check the microphone hole next to the speaker on the bottom. They've been known to fill with gunk.

microphone issues during call on android N

From the past 2-3 days i started using the 6P for voice calling and i noticed the other side could not hear me properly so today i confirmed it my self and it was true my sound is muffled at best and i have to take the bottom speaker very near to my mouth to make the other party hear. There is absolutely no sound if i held my phone normally. Please help me.

I'd advice you to check the other microphone on the back. Clean it. And while on call, do not block it, or the sound gets muffled.

Blow it, preferably with canned air. Test your microphones by recording a video where you talk and listen to it. Does it sound normal?

Recording audio from third party recording apps works perfectly. Audio during video recording is also perfect. Its only during calls the issue occurs.

Does it still occur if you make sure that you're not blocking the microphone right under the rear camera on the back? Because that's the most common reason for that.

Yup. I almost never block the mic on the rear.

I have it too, already from android M, it has to do with noise canceling. I've tried allot of things. but none of them really worked. If I put the phone on speaker, the issue is gone, the person on the other side can then hear me perfectly again. Google should fix this problem. I don't think there's much we can do about it..

IS there a fix for this I have 2 6p's with the same issue. I am happy to root one and have a test if there is a known solution.

What this does is disables the noise cancelling mic during a normal call which is the source of the issue. There is an issue in the coding or the actual hardware where the noise cancelling mic picks up on your voice as background sound and tries to lower the volume of those khz which is what it is supposed to do with everything except your voice.... When you put it on speaker mode or record video it automatically turns the noise cancelling mic off which is why it works perfectly in those modes and why this little trick that I have been doing for over 2 years now works. It is just a simple build.prop change and all you need is root access and a text editor. The application is nice to make it easy but not necessary. I hope this illuminates the issue and why this little work around actually works. Trying to clean the noise cancelling mic or other measures will get you about nowhere as it is firmly a problem with the operation of the noise cancelling mic in normal call mode. I remember when we were diagnosing the issue on some thread here on XDA and some people said to put your finger over the noise cancelling mic or that they used a piece of tape to cover it which gave the same result, so we decided to just do away with it on the software level. I guess if you don't have root you can cover it with a piece of tape permanently or your finger while you speak on the phone.
Hope that helps; decided to post for posterity.
Also, I tried the program linked and it did not change the actual build.prop file for me, but rather made a new one which was not in the right place and therefore did nothing for the actual running of the phone. All you need to do is go into root -> system -> build.prop and find "persist.audio.fluence.voicecall=true" and change it to false then save. You can leave the other ones alone. I used Solid Explorer and edited the file with SE Text Editor which I gather comes with LineageOS as I only downloaded Solid Explorer and not SE Text Editor.
