Hi guys,
i think there's a problem in my i9000;
whenever i make a call, i can hear low static interference in the background.
i searched both on xda and elsewhere, and although some other people complained of this problem, no one was able to determine the cause or provide a solution.
i tried different roms, froyo and gingerbread samsung roms, in addition to cm7, with different kernels and modems, heck i even changed my csc(just for sake of changing everything to make sure.. all for nothing. the problem persists.
Does anyone know what might cause such problem and how it may be solved?
i have exactly the same problem. Like you; i tried every combination which i can. I think main cause of the problem is hardware related. But my opinion is ,it can be fixed with device drivers. I looked at service manual. In the speaker part of the service manual,you can see there are two inductors and one capacitor before the speaker module. You can see the full circuit in Service Manual Page 42.

I think these inductors(L209,L210) are interferencing with the GSM frequencies and making that static sounds on the background.
We need someone who is an expert on linux and device drivers. Maybe he can show us to find a way to break this circuit(temporarily turn off B1 and A2 pins) in a call so it will not make that sounds.
In the other hand we may have defect phones. May be the only way is to change some parts.
sorry for my bad english.
I think there's something wrong with the speaker itself.
I'm taking the phone to samsung's maintenance to see what they have to say about it.
I'll report back once i get to the bottom of this..
Same here, but it's not constant, just happens enough to be noticable, bloody annoying, and only started (or I only noticed it) a couple of days after JVP. Will be interesting to see what you find out...
One possibility, do you have your phone in a magnetic flip case? Worth checking

No magnetic flip case, just a hybrid (plastic back+sillicon frame) cover.
I even took it off for a while to see if it was causing the problem, but no.
I went to samsung service center and they said it will cost about 200$ because the ear piece comes with the touchscreen..
Meaning i would have to pay for a new touchscreen even though i only need the ear piece.. How about that for service.
I checked ebay and found the whole ear piece+speakerphone+headphone jack in one bundle for 15$
so guess what my next step will be??
Buy and install the ebay part, sell my i9000(never liked tw anyway+cm seems a long way from home).. Had enough samsung for one lifetime
are you sure about the sound is coming from the earpiece ? i am asking because few weeks ago i was also assuming that the interference sound is coming from the earpiece . But i realized that it is coming from the rear speaker. Can you test it ?. In a call ,turn back the phone and put speaker hole to your ear. The interference sound is so loud that you can hear it from the earpiece hole.

This is the question which i am also looking for answers
Everyday i am searching for answers. Only a very few people experiencing this problem.
I think this problem is coming from the inductors in the speaker circuit part. You can look my first post .

i have this problem too, i live in Romania, i tough my phone was broken, but a friend's phone also does that.
i notice it when making call while 3G data was running in the background. If 3g is off = no noise.
Also i have noticed, the way you hold the phone affects it. try holding it with 3 fingers to your head the covering the mic hole with the other. you should hear some interference right there. so it's probably: speaker+ extra sensitive mic + some antenna things
Also my friend had the phone for some months now and never noticed it i searched the web and we're not alone, i found this discussion on a couple of other forums, still nothing to do, or nobody reported back after they whet to the warranty service. i would go, but i don't have any warranty on mine.
I'm also from Romania and I noticed this annoying issue today. All my other friend with Galaxy S also have this problem, so I guess it's a normal thing.
The only solution, I guess, is to use 3G networks, at the risk of draining a bit more battery.
so bottom line is that on mine, i hear noise/buzzing/interference when i use 3g networks both on the speaker on the back and the earpiece (it's louder if i use 3g data while i'm making a call) - the issues goes away completely in gms(2 g) mode
and it depend on how i'm holding it - it's louder if i grip the phone in my hand (probably the wireless signal is lower and the phone increases the power needed to communicate to the network thus experiencing buzzing sound from the speakers like radios did back with the first cell phones before receiving a call)
so i guess i'm not the only one, right?
This issue is normal I think. No big deal. If the noise however gets so loud that it interferes with your call, get it changed. But the new ones you get might have the noises too. So what is important here is to keep the noise to the minimum.
With / Without the noise is totally an unknown cause now. At least have it settled to the least noisy.
*This is happening to everyone who is getting the phone since November 2010
I confirm this issue with more models.
Hi guys!
Bought myself my GT-S5570 (Galaxy Mini) a couple of months ago. This is my first Android experience. At first I was pleased, but then I noticed this static noise whilst in call. It's like, suddenly I can have ill-isch, distorted, "noise spikes" sort of things. Left my phone in for service under warranty. When I had it back, it was still messy. Bought myself a GT-5660 (Galaxy Gio) a week ago, thinking that this one would clear the issue. It's still there, though. I'm wondering if this is something that affects the whole Galaxy series, even the tougher models like S/S2.
Related threads, by me:
android.net/forum/samsung-galaxy-mini/60951-sudden-volume-spike-during-call.html
androidforums.com/samsung-galaxy-s/307523-samsung-galaxy-s-gt-i9000-static-ear.html
yesterday my cousin bought i9000 too. First of all i looked for the noise. It is interesting that that phone is nearly noise free. If i gave 10 point noise to my i9000 than that phone will be 2 points. You can hardly hear the noise. After that i get her SIM card and test my phone with that sim card.Noise is still there.I make that phone software same with my phone. That phone still has no noise.
I think the problem is in phone parts. Maybe a defected series of speakers used in our phones. I will buy a new speaker module on internet. I hope that fix my problem.
For me it depends more of the network I use than the phone. It happens sometime with an iPhone.
as i stated in my previous post in this thread, in my case i was sure it was the loud-speaker, i say "was" because i sold the phone, and thats the reason why i didn't come back to this thread since..
it seems there was something wrong with the loudspeaker(on the back of the phone), and it was, at least to me, one of those things where a person might not really notice unless you're looking for it.. my bad luck had caused me to flash a certain modem and the reception was bad, so once i reverted to the previous modem i was checking for the sound clarity and that was when i first noticed the static during calls..
then i realized it was coming from the speaker, as one good man in this thread suggested. i couldn't handle it though, i could hear it every time i make a call..
it didn't make a difference whether i was on 3g or gsm or both, it was always there, unless i went into airplane mode..
so i ended up selling the phone, and bought another, but before i had bought it i put my sim inside and made sure there was no static, and there isn't, whatsoever.. thank god.
i'm sorry i couldn't find any other solution to the problem, samsung service here had said they would replace the speaker, as the part comes on its own, unlike the case for the phone speaker, which, according to samsung, is bundled with the screen, and if i had wanted to change it i would have had to pay something like 200$ to fix...
those who have this problem, check if its the loudspeaker on the back of the phone is the actual culprit, and if it is, try to find a way to replace it or something, that is if it bothers you this much. or you can just sell the phone, there's a 99% chance those who buy it won't notice anything, because they're not looking for it..
good luck guys..

Hi,
First post, so apologies if I'm posting in the wrong place, but I wanted to find out if anyone else is having trouble with the speaker and microphone on an S730?
I eventually received my handset from O2 UK (XDA Atmos) and managed to make 2 voice calls before the speaker stopped working. I can place calls but I can't hear a thing (completely silent), and I no longer have any key tones.
On investigation, it works fine using the supplied headset, and if I grip the phone in a particular way so to gently squeeze the top section, the speaker works again.
I've googled until I'm sick and can't find any references to this on a 730, but quite a few on the 710. Anyone else had this problem.
Oh, and just to really annoy me, O2 are out of stock, so their next day replacement is going to take 18 days!
If pressing on the case kicks it back in it sounds like something is not connecting properly anymore, its possible you could fix it but I would go for the replacement. Does the external speaker still work? I have not seen any other threads about this issue but I am sure we will.
It's hard to tell but I believe the external speaker works as it does ring. However, I'm not able to switch it to speaker phone mode. Doing so does nothing. I also seem to have more luck placing calls than receiving them.
I guess I'll just have to wait for the replacement. Bit annoying that my 'loan phone' from O2 is a nokia 6300 though - hardly comparable! Just hoping the replacement doesn't suffer the same problems...
You sir are the first one to report this issue that I have seen, doesnt mean its not but I wouldnt bet on it being too widespread of an issue. Sounds more like something went wrong in shipping / production and you got unluckey Hope your replacement shows up soon!
Well, my replacement finally turned up today..... and it works just fine. Let's hope it was indeed a one off, or damage in transit, or cosmic rays or something.
I've had my AT&T banded N1 (with Rogers in Canada) for nearly 2 weeks now and I've been waiting to make sure everything works properly before I potentially give up my warranty by unlocking it. One thing that has been bugging me though is the call quality.
Everyone raves about how clear the call quality is on these things, but based on my phone I don't really agree. When no one is talking the line is dead silent (so silent that I almost think that the call has dropped), but when the other person begins to talk a light static or crackling background noise starts and once they finish talking it goes away and is completely silent again. If the static was there all the time I might not even notice it, but since it stops and starts during pauses in the conversation it really stands out. This happens on both the handset ear piece and with the headphones that came with the phone.
Has anyone else noticed this? If it's normal so be it, but if not then I might as well try and get it fixed before I do anything.
I don't have the at&t version but that does not sound normal.
Crackling is normally a sign of a speaker problem but I wouldn't think the headphones would also produce it.
seems i have the same issue...
i havent noticed any noise like this, but i will go test it and see if i have it too.
It's the speaker, for some reason the Nexus One comes with a slightly-too-loud speaker volume setting built in and you need to turn the incall volume down one notch from max. At least that solved my problem, hope this works for you!
have just called Google Tech Support and the guy suggested me to blow into the earphone couple of times and see if it helps
if not, do a hard reset
if not, call for warranty...
Since I get this noise in both the handset and ear phone speakers at all volumes I have to assume the problem is with my radio.
It's too much of a pain to get warranty work done outside of the US so I'm just going to learn to ignore it.
So I recently rooted my phone and installed CWM and currently am using a Nandroid backup of the Tmobile Stock ROM. Here's my issue: The microphone doesn't work when making phone calls. I'm trying to figure out if it's an issue with the phone itself or if I did something when I rooted/flashed a rom. The speakerphone microphone works but in regular calls, nothing gets picked up by the microphone. Any ideas?

I think we have the same issue. Here's my thread regarding my problem:
http://forum.xda-developers.com/showthread.php?p=41872872
People on the other line say my voice is very muffled and distant. And I also don't hear anything on the right side when recording a video. It must be a defect with the bottom microphone. I wish there was a fix rather than having to get the phone replaced.

Thanks for the reply. Is your new HTC One working correctly now? Clearer sound on calls and records both left and right channels of audio?
Also, you said you went to the dealer to get it replaced. I ordered my phone from T-Mobile.com and they said I would have to mail it in first and then they'd mail me a replacement. I wish there was an easier way.

I went today, and for the moment it seems to work okay, I brought my phone directly from the dealer, and they replaced me with another new phone.
It's definitely an issue with my bottom microphone because when I make a call using the speakerphone, the other caller can hear me perfectly, since the speakerphone mode uses the back mic. But regular calls using the bottom mic sound awful.
Has anyone been able to get a replacement that has resolved the microphone issue? I just bought my HTC One from T-mobile a little over a week ago and I'm debating whether or not I should return it to the store to get replacement(which may have not solve the issue) or to send it to HTC through product warranty and hope for them to repair it.
I've got the exact same issue here in Australia, just the last few days when I make a call the person at the other end can hardly hear me but when I put it on speakerphone its fine. Looks like I'll have to return it. I bet I don't get a replacement. Over here the phone has to be sent back to be fixed. I had terrible issues with my Galaxy S3 that was finally replaced after being sent back twice. Thought my luck would change with the One but looks like that isnt the case. Very frustrating.
Can anyone shed any light on this issue yet? Mine messed up out of nowhere... Went to a concert a week ago and recorded a video and it sounded fantastic, a week later however, when I record a video all I get is very loud static. Same goes with voice calls. If I set it to speakerphone they can hear me fine. Idk whether to contact HTC or AT&T I have the insurance + warranty.
Any help would be appreciated. I don't really wanna flash or root it yet because of warranty issues and what not.

I had the same issue with the loud static through the bottom mic but mine was from dropping it no more than 3 feet from the ground with the otter box on. I had my carrier send it out for repairs and the replaced the flex board and the bottom speaker and mic and since I've gotten it back, I have no more issues with static on my phone calls.
However, I am getting a lot of complaints of people not hearing me when I speak or it sounds like I'm too distant. Now I'm frustrated.

Hmm did it cost you any money (if you don't mind me asking)?
HTC wants me to ship it out and I haven't contacted AT&T about it yet.
Idk what the better choice would be!
I'm glad your static issue is gone though! It's very frustrating to not be able to make phone calls on my cell phone...

It didn't cost me anything as it was under warranty. I got the phone the day it was released.
I'm not sure how it is in America, but I'm with Rogers and they deal with all repairs. So, they sent my phone out to HTC and had it returned to me at no cost.
To be honest I don't even know how it works here either. I've never had to send a phone back.
It's seems as if I can go through HTC directly or through AT&T.
Looks like im going to have to do some research!
Same problem, just crept up out of nowhere. Speakerphone works during calls, but callers tell me I am going in and out, so I was like, what. I tried to record a video right next to my tv, no audio. Hmmm, opened voice recorder and I was yelling into phone and it came out almost silent. Voice search is also useless unless I scream at my phone, that's what really started this whole thing wondering what is going on as I really do use Now for alot. Owned phone from day one, 64 GB ATT model. What gives.

I dropped my phone from literally four inches above a hardwood floor - EDIT - possibly relevant detail - I dropped it while in the act of recording video - and had serious static issues immediately after that.
Before sending it in for repair, I tried gently rapping it a few times in various ways ( see http://en.m.wikipedia.org/wiki/Percussive_maintenance ).
I also experimented with recording a few really loud sounds thinking some kind of automatic gain control on the dual membrane mic may have gotten stuck at an extreme value.
One way or another the problem went away and never came back. I consider myself lucky.

I just called HTC and they have basically told me I am out of luck and aren't going to do a thing for me. I purchased an unlocked AT&T HTC ONE brand new for 800 ish dollars. Since I am in Canada, that's their loop hole I guess. Either way, I don't care what country I'm in, I paid 800 for a product that clearly has a hardware issue.

This is how I fixed mine.
Start the recording app, you'll see that the visualizer indicates that it is recording sound, it's the static.
now grab 2 bristles from a toothbrush and gently stick them in the bottom mic
rotate them gently, you'll notice the visualizer getting smaller if you're doing it right, means less static coming in.
do this until the static is gone. worked for me, took 5 minutes.
Same Issue
I am having the same problem now. My phone is one month old and it was working fine and then i rooted the phone two weeks back it still was working fine and then today suddenly i didn't hear anything when my friend called me thought it to be signal issue then it happened same with every one of my calls. Do i have to unroot and lock my boot loader before i take it to HTC or at&t?
Possible Fix
Hey all,
Here's what I did to fix my Sprint HTC One
I went into system --> build.prop
I changed persist.audio.handset.mic=digital to persist.audio.handset.mic=analog
Reboot
This solved my issue after I've tried many things. Here were some temporary fixes that worked for me before I found this permanent fix:
Screaming into the microphone for around a minute. After that, the rest of the call seemed to work. Note: The microphone is on the bottom, underneath the bottom speaker.
Covering the second microphone that's on the BACK of the HTC One (you'll see it in the top right). That helped as well.
I hope this helps someone.
Cheers.
I too had a problem after about six months... No one could hear me when I spoke into my phone. So I took a needle and carefully put it in the small hole in the bottom, scraping against one of the sides - and voila: up came some pocketwhool (is that the word for that hairy dust that comes out of nothing in the pocket all the time...?)
The microphone has worked perfectly ever since... ??? ?
Hello,
This might be a double post, but nevertheless I have noticed a strange buzzing noice from the top speaker. It seems to occur when i switch wifi off and then on. At that moment when it is receiving and sending data. It seems that the speaker comes on and creates it. If i have to discribe it i would say it sounds like electrical currence or a something shortcutting. Anyone else with this problem? I mailed my provider today and i am looking to send my device back soon.
Also, offtopic, i noticed that the screen isnt positioned properly, on the left side it sticks out...
For me two reasons to look for a replacement nexus 6.
Regards,
Elroy
I'm on my second phone and I'm noticing this too. Its fairly quiet, but in a quiet room it becomes very noticeable. It seems worse for me when the CPU is really going. Also, if I turn off and on the screen it gets louder. I actually noticed this issue with my first phone too, but I returned that due to a camera issue. It might just be interference from the CPU getting into the speaker. Not sure if returning it will help. Sucks this phone costs so much but we gotta deal with issues like this.
We have so many this speaker related issue. plz search.
Don't waste your time replacing the phone because all has it. It's more likely either SW can fix or just a pure dumb HW design by Motorola.
Bought Xperia Z3C and from the first day some calls didn't work well... Others couldn't hear me about 60-70% of the calls, sometimes they heard like strong wind is blowing into the mic and when I put the call on loudspeaker then it worked, they heard me loud and clear.
So I took the phone back and ordered a new one, cause I really like Z3C, even more, if it would work with no problems
So my new, second Z3C, same green beauty - but same problem! I tried repairing with the first phone and tried doing the tests, neither helped. Only this time about half of the calls act like that. Sometimes if I put the call on speaker and then back, it works again, but not always.
So my question would be - Has anyone else had this kind of problem? And if so, what did You do? Is there even anything to do? Is it hardware or software?
There is no other phone I would like but it would be silly for me to try the same thing third time.
sorry to hear that,i guess that when you take the calls ,you cover the loudspeaker at the bottom of the phone

Similar thing happened to me, I had to yell first few days untill I discovered I had a bad habit from old mobile phone.
When i talk and holding the phone, my thumb is on the one side, three fingers on the other side, but that little finger is on the bottom, like i hold the phone not to slip down.
And the mic is positioned exactly so my little finger would cover it. That was my reason people couldn't hear me.
I doubt it's your case, but try to see if you do the same thing
Agree with others -- the mic is in a slightly odd place and I had to adjust the way I hold the phone to avoid blocking it in some way. Aren't the mics usually on the bottom left instead of the bottom right like the Z3c?
exact same problem

I have the same problem in All voice communication apps and normal calls.
If i test the microphone at The built in test i get no problem but in skype, Facebook and All other things that uses my Mic it cuts off and makes a windy sound. I was allmost ripping my own head off in anger and confusion because everybody i call is making me say things 5 - 10 times. And now i see im not the only one... What to do? Great phone beside that and headphone and aux volume is adjusting it self..

I had this kind of a problem on the latest firmware (.77) sometimes. How about you try downgrading to an older firmware? Like the .93 firmware which can also be rooted

Got the same problem. After disabling "noise cancellation" (not sure how it's named in English FW) in settings > Call problems is resolved.
But now everyone hears everything within range of the main mic and thats not cool.
Can anyone confirm its related to 23.0.1.A.5.77 Firmware?
On previous version didn't had any issues except phone went underwater and died, and new one is already on the newest fw ;/
Don't want to do root due to guarantee issues after this.

+1 the same issue,
serviceman flushed the original firmware twice
nothing helped, they even refused to refund saying that they can not identify the problem .
Farewell guaranty, I'll try CM mb that will help.
The problem is floating, suspect bad mic contact or bad capacitor installed.
both require disassembling for proof.
Service tests shows that mic is ok.
Does anyone know how to get voltage\capacity curves from mic without disassembling ? mb some test pins on the back ?

+1 the same issue,
serviceman flushed the original firmware twice
nothing helped, they even refused to refund saying that they can not identify the problem .
Farewell guaranty, I'll try CM mb that will help.

Do you can tell what is the sound recorded by 2nd mic? Mine is very low, like almost subwoofer
And on what Firmware you are?

Bought Xperia Z3C and from the first day some calls didn't work well... Others couldn't hear me about 60-70% of the calls, sometimes they heard like strong wind is blowing into the mic and when I put the call on loudspeaker then it worked, they heard me loud and clear.
So I took the phone back and ordered a new one, cause I really like Z3C, even more, if it would work with no problems
So my new, second Z3C, same green beauty - but same problem! I tried repairing with the first phone and tried doing the tests, neither helped. Only this time about half of the calls act like that. Sometimes if I put the call on speaker and then back, it works again, but not always.
So my question would be - Has anyone else had this kind of problem? And if so, what did You do? Is there even anything to do? Is it hardware or software?
There is no other phone I would like but it would be silly for me to try the same thing third time.

I had this problem, people did not understand what I said, TrackID was struggling to identify music. I left a message on my mailbox and could barely hear, changing the phone position helped a bit but it was still not loud. Sent the phone in repair and now it's perfect, I can whisper and people understand me

You had issues with the main mic - I do not have (luckilly) such an issue. Only 2nd has some problems, but if I launch service tests it records sounds fine. With different quality than 1st mic but records properly.
Mine was recording fine in service tests also (replay sounded ok), but it was apparently not sufficient in calls. I think the service test is very sensitive, with my repaired unit I can whisper at 10 cm and still perfectly understand on the recording.

Please post reply to those questions:
1. Do you have enabled noise-cancelling function.
2. Which mic you test in service menu?

1) Tried both, no difference
2) Tested microphone
Microphone in Z3C is the worst part of the phone
Im also have problems, or people Im talking to via phone, cause previous phone which I still have - SGS 5 mini - has very sensitive mic.
Both my phones are watter proof, also has special membrane, but when Im callling one to another difference are HUGE.
I checked 2 phones of my friends, and thier Z3C's have the same sensitivity, but the dont complain, as suppose they are usualy yelling
In SGS5mini I can rotate phone around the ear and still very louldy and clearly someone can hear me, thera are little diffrences ofcourse, but in Z3C where even when Im trying to have microphone close to mouth sound is much quieter - moving the phone little bit and conversation can be irritating.
It already pissed me off 3 times so much that I ended conversation, because of complaining of the other people.
P.S. Before someone will ask - yes, I disabled noise cancelling function from the begining, also trying different sound settings in call and sound menu.
SOLVED - at least in my case
What I did till today was:
disable any sound "improvements" in menu
cleaning microphone hole with compressed air
After test I saw little improvement, but still I was merely heard by other caller.
Looking mixer_paths.xml tried few times changing parameters and found the right one to rise sensitivity of internal mic.
Below are unchanged section that I'm talking about - in bold specific value that we can rise.
Code:
<path name="handset-mic">
<path name="adc4" />
<!-- 67 % of 124 (range 0 - 124) Register: 0x231 -->
<ctl name="DEC3 Volume" value="[B]83[/B]" />
<!-- 63 % of 19 (range 0 - 19) Register: 0x15F -->
<ctl name="ADC4 Volume" value="12" />
</path>
I choose value=92 as this found to be still safe (don't use to high values as it can damage your device) and I'm pretty happy now of my Z3C
Prepared MOD for this change to apply from recovery.
I've sent mine for repair. They said everything is ok, since repair service does not test calling in real life - just service tests, where this issue is impossible to catch. Had to ask them for "special" test - calling from my phone to somebody, and checking the difference between Noice cancelling feature turned on and off.
Hi any mod for stock ?
My wife have z3c everything was fine just one day start cut off world etc.
Will try with disabled reduce noise option
Any other solution ?
Guys I had the same problem, solved it today
Mine was running latest android 5.0.2(23.1.A.1.28) Z3 compact.
In my Music application(Walkman app updated to Music)-settings-Audio Settings- Mic sensitivity set to High.
Other person can hear me crystal clear
I suspect this is a Bluetooth related issue. I have my Bluetooth always on and when driving and calling there is no issue on car kit. I found an workaround, when calling before connected I press loudspeaker and mute unmute
