Hi there,
At my SGS2 it seems the microphone hole next to the microUSB cable, is not open. Everybody complains they can't hear me.
Sure, I can send the SGS2 back, but then I'm won't have a phone for the next couple of weeks.
Does anyone know, who already disassembled the SGS2, what this could be? Some soft plastic which I can easily remove with a needle?
My last option would be send it back, but maybe you guys know an option?
Can I use some audio codes for cranking up te mic?
Thanks!

Hmm .. seems I have the exact same problem here. People are complaining they can't hear me and they hear a terrible echo. Tried with headset, problem solved (of course ) Not sure if it is not open, I can see something gray inside the hole, which could be the mic. Disassembling is not an option for me, just got it yesterday so .. if there is really something wrong I will go back to the store asap.
I am disappointed about this, really, expected a lot from this phone to replace my Desire.
EDIT: tried also speakerphone, then it is all normal. Speakerphone uses the mic on top near the headphone jack, I just found out. It looks like a faulty mic to me (or covered with something).
EDIT 2: Fixed, although people say that with my previous phone the quality was better. Reset to factory defaults did the trick for me. It seems that the firmware update the other day (used Kies) had messed something up, that is my guess.
New device
Well, I kept holding the problem. Yesterday in the morning all was fine, in the noon people kept telling they hear me with bad quality and an echo. I went back to the store, explained the situation, they gave me a new device. I can clearly see the difference in the microphone hole .. the first phone it was closed, here it is more open. Problem should be solved now, I hope. I can say that I tested the quality myself and I can hear the difference. The sound of voice is more clear and louder.
I think it is word a shot for you to try to change your phone for a new one.
Hi there,
i have been noticing a very strange behavior in my phone these past two days...
my phone is on this firmware I9100XWKE7_CPWKD1_XXKE4 rooted with insecure kernel...
nothing fancy just regular apps
i noticed that when i call or some body called me the mic dosent work at all ...
he cant hear me
switching to speaker ... every thing is fine
rebooting --- no effect
connecting to the charger and then disconnecting the problem is gone -tested once-
Skype testing service ... the same problem the mic only work when in speaker phone
so after this i started thinking it is a software rather than firmware
any ideas ???
encountered the same problem with my gf's lg optimus 7. the mic was defective, there was a short circuit of some kind. had it replaced ( the mic) and everything worked good.
maybe there was some water or some sort of liquid that reached the internals.
nope no liquids ...
this is really annoying this is my 2nd phone the first one had a very loud noise on vibration
gonna do factory reset now
but it appears that when you scream really loud the phone will pick something probably from the noise canceling mic ...
i am out of uk now so going to samsung is not an option right now
so after a factory reset ... it appears that the mic is broken it dose pick very loud sounds though
Hello all
Got the S2 recently...was an HD2 user (with android) and am really impressed with the performance of the S2..though I am not too happy with two things.
- Battery...i just got the VillianRom installed..and I hope to see an improvement there..
- Ear speaker jarring...the ear speaker seems to crackle at certain frequencies. I checked the whole forum and there were some others with the same complaint and was asked to use the Volume+ app..which I have and to be honest i dont see much of a diffrence..the crackle is still there. I want to be sure if this is a hardware issue or a software issue...and how can I really solve it?
Can someone help?
ah.. another fellow s2 holder that has this issue.
YES! I have the same problem and its driving me crazy!!!
its random, and its buzzes, crackle or even sounds like the earspeaker is blown!
What have you done with it? I think I'll probably go change it but just checking here if you have found the solution?
there's one person with a vibrant saying he blew hot air into the earspeaker and it solved the problem (dunno if its advisable) and he didnt say how did he do that.
I seriously have no idea what you're talking about. I use Spotify non-stop on my SGS2, no crackling thing.
I'm not talking about the back speaker, its the front one where you listen to when you're in a call.
Hello! I have the same problem! Like it is distorting. I will take it to service centre today.
I really can't remember I posted that, my bad.
ok I got back my phone from Samsung Service Centre, after a second persuasion they changed the front panel (whole LCD including the front speaker, not sure if the back speaker too, I don't know the structure of the phone).
And now, it's solved!! NO MORE BUZZING when making/receiving calls!
Definitely go ask for an exchange or a change of your panel guys! It's a HARDWARE ISSUE.
Thank you for your answer! I have the same problem. They dont belive that is something wrong. They changed the speakerphone and no solution. Now they tell me that must be something wrong with our network, which I dont belive... I was also suspecting that all have the same problem, they just dont recognize.
Thanks a lot!
Hello.
Recently, I had to replace my digitizer because of cracks. While doing that, I also replaced the ear speaker, because the sound, that was coming from it was very quiet and distorted. After doing that, there is now no sound coming from it. I have followed the oficial repair manual, also double and triple checked how I installed it, everything seemed fine. Is there something more, that I need to do or is it a deeper hardware fault? One more thing - how can I check if the replacement speaker is working without installing it in a phone or something like that?
Any help is appreciated.
hi..just bought this phone about 2months, now i'm facing No sound/audio at all, here's some detail and if anyone of you any good hardware repair skills here, i need your help, as i believe100% it's not the software issues:
1. phonecall, on stock MIUI (NoROOT/customkernel,pure officialrom) its freeze/hang when dialling numbers - few second latter its rebooted itself. voice recording app won't work can't use the app as its error pop-up said, and sometimes i need to hard restart to use the phone again. and its gime bootloop and drained battery (4000mah cannot even survived for 7hour), even with no internet connections the battery still drain fast.
2. when someone calling me,there's no ringtones, even when i answering the call there's no sound at all, no musics sound, any audio files i play only hisssing/noise sounds i can hear just like feedback sound.
3. Unlocking Bootloader, replacing other rom the sounds completely disapear, no hissing,noise at all (CM,Mokee) and still phone app freeze/hang when i try make a phonecall,(reboot/hardreset)the only solution to make the phone back in usable state.
4. installing Citrus ROM, the sounds back but only hissing/noise sound on sometimes i can here the sound with some feedback issues. phone app works i can make a call without freeze/hang,no reboots, but i can't totally hear someone talk to me at all, but when i turn on the loudspeaker i can hear someone talk to me (with some annoying feedback sounds),
5. as i bricked it once and need to reach testpoint so i believe its not under warranty, seal already broken.
6.ordering the parts, connector charging board(which contain whole set new audio i guess hope can fix the issues, but just noticed that if that's part causing the no sound issues, its only fix the audio such as music,ringtones..not the front speaker(phone related still not repairable)
7. trying contact some friends which some understand about hardware told me, i break down the IC Audio so its imposible to repair/change that part since its directly micro-soldered to the mainboard.
anyone have same problem as mine?, or some of you have solutions for my problem please reply .thanks

Same problem as mine.
Even the video recording do not work too.
Is there any solution how to fix it?
I use it as ipa/od without ability to make / receives any phone call, so many ppl has the same problem here seems was Xiaomi's bad hardware components, which mine believes caused by sudden-removal audio/aux jack while its still playing the musics
anyone know the average price to fix the sound ic compared to the phone? maybe 10%, 25%, 50%, or above the price of the new units?
I have the same problem,, could any one tell me where I can buy the hardware (IC sound).
Plz tell me solution. My mobile mi note 3 audio problem, audio only listen Bluetooth.

Redmi NOTE3
I need audio IC for Redmi NOTE3 we're can I buy
hello.it is an old topic. i hope it be useful for anybody else. a few days ago My redmi note 3 pro kenzo was damaged by water. after that when I turned it on, logo of my custom ROM was appear and boot loop ... First I think it was for ROM or kernel. I installed another ROM with other kernels. I could turned on my phone and enter to user interface. but everything that was related to sound ( like : camera-music-call-headphone,... ) was not work at all. I searched a lot. I found out the problem is for Audio IC (WCD9306 Audio IC) this model. https://www.deviceparts.com/wcd9306-audio-ic-for-xiaomi-redmi-note-3-ori.html
it is used in Samsung mobile phone like S4. however you can buy it. but the main problem you can't change it by your own without tools . if you are familiar with hardware it could be useful: http://www.u2ugsm.com/blog/xiaomi-redmi-note-3-ringer-solution-jumper-problem-ways/
I think cleaning IC with cleaner or alcohol might be useful. good luck
Edit: After 4 hours I turned it on and sound is back! I just cleaned it by alcohol and cleaner. but I made mistake. a little bit of that alcohol-water liquid is entered in my LCD screen. I put it in warm place and hope it will get better.
