I recently purchased 3 Galaxy S3 phones, all of them model I9300T.
I am experiencing a very strange issue, where on some calls they are getting very poor sound quality, with severe static or scratchiness over the whole call. Sometimes there is no sound at all, and both callers only hear silence. The poor sound is not just on the call, but also the dial tone and when the caller hears the voicemail recorded message. This only happens when some numbers are dialed from those phones, and not others, and not the same numbers for each phone.
I don't even know where to start in troubleshooting this, as I can't even decide if it's a SIM card issue, a firmware issue, a hardware issue or a network issue.
All phones are running current MIUI.us (based on ICS 4.0.4) with i9300T modems for the i9300T. I have tried different modems in all handsets, which has not solved the problem. I have not tried different firmwares, I have looked for stock firmwares, but I cannot find them. I usually get my stock firmwares from XDA but I was unable to find a thread for stock firmwares for the i9300.
Has anyone seen anything like this before, or can anyone offer any advice on the matter?

Well, since you recently purcheased them, then perhaps sending it back to the service center will enlighten you.. make use of your warranty
but before sending it to the service center, do use triangleaway and flash a stock firmware.. put everything back to stock
Cheers!

Given that they are all (three of them) exhibiting the exact same problem, and given that the problem is not on all calls, I highly, highly doubt that it is a hardware issue. I'm thinking that this is a bug that is being triggered by some combination of software on my devices and network-side settings.
I'm running I9300 ROMs with I9300T modems. When I reflash stock, the problem goes away.

I see.. mmmm. Have you tried going to recovery and wiping caches and fixing permissions? It's what fixed some problems of MIUI users

I'm a fairly experienced ROMer, yes I've tried all those tricks. I've also tried other variants of MIUI. I am in the process of trying other ROMs to see which ones trigger the problem, and which ones don't.
Note that this is occurring with I9300T phones running I9300 software on a 850mhz network. I think that has something to do with it. I would like to test the issue on a 900mhz network to see if that still causes the problem to manifest, but that would require much effort to go any buy prepaid SIMs just for this test.

Hello there,
Is there anyone else having this issue (people can't hear) with ICS Passion?
I tried some many different configurations, modem/radio, kernel... my carrier is Wind Mobile in Canada. Not sure if the problem is related with the ROM and the carrier, or what...
Thanks.
Do you mean they can't hear you after they call you, or they can't hear you after you call them. If they can't hear you after they call you, it's because of the mute/unmute bug with all Vibrant ICS roms. All you have to do is, when someone calls you, right after you answer it; just push the must button twice (hence mute/unmute) and they'll be able to hear you fine. The mute button looks like a microphone and it's in the center on the bottom.

Hi!
It is not the mute/unmute issue... it actually doesn't matter if I call or someonee calls me... everything goes fine till like 2 minutes (this time may vary) of conversation... then suddenly the other side can't hear me for a while... but more curious is, if I press the dial buttons, the tone sound goes to the other side... so it is definitely an issue related with the microphone.
For some weird reason, modem JL5 / nelson kernel 2.2 was the best combination so far, considering all the combinations (kernel/modem) I have tried... but it still happens, eventually.
No clue about what to do..
Well, try a different rom altogether.
I'm having the exact same problem and it's driving me crazy! I'm also on wind mobile in London (Canada). I used the phone a few months ago on Fido and never had a problem so it definitely relates to the AWS part of the phone. I haven't tried every modem, but I didn't notice much improvement between the ones that I did try. Originally, I thought it was an issue with Euphoria, so I tried different ICS roms with no luck. Since then, I've restored to stock and I can make calls that last much longer but ultimately suffer the same issue. This implies that it may be a software issue. I'm going to have to get a new phone if this continues. It's frustrating considering how far the development of ICS roms for the vibrant has come.
Edit: I just wanted to point out that I had the nexus s working perfectly with wind mobile so I don't think it's an issue with the carrier. My sister had the vibrant for a while and she would complain non-stop about dropped calls when I put froyo-based or ICS-based roms on it. At the time, MIUI was the only rom that she didn't have calling issues with. In an attempt to fix the phone myself, I gave her my nexus and took the vibrant. I've tried miui but this issue of others being unable to hear me during a call persists.
How long do your calls last using the JL5 and Nelson 2.2?

Hi! Well, yesterday I got a call from a 1800 number and had I think 5 minutes of conversation before the issue started... I remember with KB5 I could never have more than a minute...
so, that said, and since "I found" someone else having the same problem, I am wondering what to do now... with some many tries we had in our phones, it is definitely an incompatibility with Vibrant and Wind.
I read some people having this issue with the Google Nexus in one other thread, and it seems a new modem solved the problem in their case. We, with this lack of support from Samsung will for sure not having anything new from them. Maybe Wind can do something in their network. Have you ever tried to contact their customer support?

I haven't, but it looks like two other people from London with similar vibrant issues have (community.windmobile.ca/windmobile/topics/people_cant_hear_me_when_i_call_them?from_gsfn=true)
From what I've gathered so far, it looks like an incompatibility between vibrants and wind. Are you from London as well?

Hi. I have problem with my Optimus One.
When talking with someone on the phone, OTHERS can't hear me well i.e stops at the moments - but I hear him very good. I'm from Macedonia on VIP network.
I've tried to root (before I have android 2.2) and flash CyanogenMod7 (2.3.7), but problem still exist. Today I've installed AOKP ROM (4.0.4) but still some problem.
I think that this is not software issue. How can I solve the problem ?
If you are not having signals or coverage issue, then this might be due to hardware (as you already have flashed different firmwares).

your microphone is broken!
Hi all
Am I the only one experiencing microfone problems on my new galaxy S3?? Im on my third I9300, because of this issue...
People complaining about that the mic vol goes up and down...
I'm also facing similar issues. I'm going to get mine replaced also.
First of all guys make sure 100% it's not the mic. Record some song and see if you still have the problem. I was facing similar issues with the mic going up and down durring calls.
In my case it was the simcard. Don't ask me why, because the same simcard was working fine in another phone, but after getting a replacement everybody said that they can hear me a whole lot better.

I am going through the very same issues.
I had a mic problem with my first S3 during phone calls. It was really annoying me because I couldn't do anything about it everyone was saying they couldn't hear me etc.
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. Thank you.
I am getting the same issue but not everytime. I am sure that it is not the fault in mic that is causing this problem, as i recorded my voice (using both mics, the one at the top and at the bottom) and it was crytal clear.
turn off Noise Cancelling... fixed my problems
same problem
Had the same issue ,also with the s 2 , but the trick then (witch also worked now ) was to turn off the noise cancellation .
During a call just take the phone away from your ear and under the callers picture there u will find the option to do so
I have literally just started having the same issue today.
Am on FoxHound Rom 1.4 with Siyah Kernel. Had no problems, even made calls last night, perfect.
Then I tried switching Fast Dormancy on, flashed stock kernel and this morning I find when I made calls to Orange customer services, they were saying they couldn't hear me.
Tried testing it myself, and no matter who I call no-one can hear me.
I've tried:
re-flashing rom, kernel
Tried latest stock roms such as I9300XXBLG8_I9300OXABLG8_I9300XXLG8_HOME.tar.md5, none have made a difference. Even Roms I had backed up in clockworkmod that were working perfectly, like CM10 preview and CM9 have stopped working.
I've tried disabling Noise reduction, which has had no effect. Tried factory reset, flashing modems, kernels, roms, stock roms, nothing has made a difference. I can record video, google talk, anything else fine, just not get anything from the mic when making phone calls.
Tried putting a friends 3 SIM in, and the same thing, so it's definitely not network related either. I definately hope it isn't a hardware fault, as I bought mine on ebay and it isn't insured. Was kinda hoping for more than 2 mores usage out of a phone :crying:
Hi

Have you tried another ROM, restore backup etc. In short, what measures have you taken on your own to troubleshoot this problem.
- yes, the phone uses another means/ Mic when you are using loud speaker

I've had this problem since about 2 months after i received the phone, I posted the question here last year but no one knew. hopefully you can get a answer!!! I'm just so used to using my phone on loud speaker now every time somebody calls haha.

Unfortunatly i was out of the country when it happened so i was never able to claim warranty on the phone or anything so i've had to live with it.
I have tried everything i can think of to try and fix it. Different ROMS, diferent kernals, different modems. nothing has fixed it.
One thing to note, is that when i have headphones in, the mic is fine. Would the be some trickery i could pull to make the phone always use the loudspeaker microphone, even when in handset mode.
current rom is paranoid android 1.99 w/ dorimanx kernal.
i think that lower mic is used when speaker is off , but in speaker phone it uses the the upper mic.

Sorry about that.
Your own case looks like a definite hardware issue. Too bad you are out of country but if you can still visit any Samsung service center, you might be lucky. Those guys are always very nice and helpful to customers in my country even if you are out of warranty.

I've not flashed a newer ROM to see if is that yet as its my wife's phone and I've not had time to back it up before I flash.
I have the same phone and not had this problem
I've also posted in the neat ROM thread and no one has had the same issue
So if there is two mics do you think it could be broken

Since its your woman's phone and you can't probably flash a new ROM at this moment, fine.
I'll say, let's assume it's as hardware issue.
I'll advise flash back your stock original or officially update firmware, And just send it to service center for repairs like normal warranty claim.
Good luck

ok guys still need some help with this
things ive now tried
flashed back to stock
taken phone apart and made sure the mic is plugged properly
got a new mic and swapped the over
still no joy
when in a call if i blow at the mic the other person can hear it but cant hear my voice at all
also tried this http://www.ctrlplusz.com/2011/06/fix-for-low-microphone-volume-on-the-samsung-galaxy-s-ii/
but it says that the menu is blocked
but even if that was the problem surely you would be able to hear my voice a little bit
hi
quick update
IVE TRIED EVERYTHING! ha ha
when i blow into the mic at the bottom really softly the mic still pics it up nice and loud. its like the phone can only pic up the high pitched frequencies
Hey guys,
Does anybody who ever or being suffered from the call issue like hearing nothing from the receiver during phone calls(I am using I9305 and I know some people have the same or similar problems with me)??Sometimes it work,but sometimes it doesn't!!And the speaker works in most of the cases,whereas sometimes it also breaks down liked the receiver.Moreover,I can hear some cracks from the receiver in some cases.
I am totally freaked out because I am sure that the receiver is good (no problems with skype and wechat,and I also have checked it by using "*#0*#" when the situation happens) and it seems impossible to be solved after wiping and flashing different firmware(both by cwm and odin),and so do the modems and kernel including Perseus.
Today I found sth strange about the call issue by chance: when I lock the screen maybe for more than 5 mins,then wake it up and make a phone call soon,the receiver can't work every times.However, when I put it into use(light the screen) for more than 3 or 4 mins,and then the receiver works again during calls.
What I want to say is: maybe there are sth wrong with the cpu setting or the power management.
Any solutions or suggestions will be totally appreciated!!!
Maybe try flashing different modems? I had this problem too awhile back and flashing a modem fixed the problem.
