[Q] Problem with microphone - Galaxy S II Q&A, Help & Troubleshooting

Hello guys,
My problem I am experiencing is with the microphone that picks up sound for videos and voice recording. In calls, it is fine, as the gs2 has 2 seperate microphones? One for calls and other for videos/voice recording.
Anyway, the problem started around 2 months back, it then disappeared after blowing into the microphone hole at the bottom. Now recently, it randomly began to not work again, so the same old static/screetching when recording was present, it even started to not record anything at all so I tried to vaccume it to get dust out, and it then started to record static and very distorted audio.
I left it a day, and WALLA! works, but now it has gone back to not recording any audio at all...
I'm not sure if this is hardware or software related?
Any light to be shed on my problem/suggestions would be really great, its still under warranty as well by the way.
Regards,
Carlos

It sounds like it may be damaged. I'd send it back for repair/replacement.
Incidentally, the SGS2 does have 2 microphones, but one of them is used for noise cancellation. It uses the same mic for both calls and recording. If it's 100% fine for every single call, but bad on video/audio recording then it may be that the recording level is a lot louder than the usual in-call level, and that's why you're getting different results.
Incidentally...

[Q] Microphone problem

I have a strange issue with my microphone or maybe I should call it sound pickup, on my SII.
When I take, or initiate a call, the sound quality of my voice on the other end is terrible, when I use the built in microphone. and I mean LOW ... like it almost sounds like I am not talking into the mike at all...
If I have the wired headset engaged, or a bluetooth one and take, or initiate a call, sound is excellent through the headset. But if I during the call, disconnect the headset, and reconnect it, the sound is also terrible through the headset.
I had my phone for a while running on Lightning 1.2 and sound was great, before sending it in for repairs (battery was faulty). After I got it back, I quickly flashed it to Lightning 4.2 and I can't remember if sound was working before that. I couldn't wait to get Lightning back on instead of the built in crap.
I've tried flashing other roms and kernels, but the problem remains the same.
Any idea's??
I am aware of these threads where people have similar problems, but I haven't heard anyone describe having no problem with the headset, but having a problem when de and reattachiong the headset ... sounds like sw to me. !?!??

have same **** and i search entire forum i heard another ppl have this problem
did u try between ur calls to disable the noise reduction
Hi, yeah I tried disabling noise reduction, and it didn't make any difference. It actually got a little worse, according to my GF but not much.
Can you reproduce that it works fine when using the headset at the beginning of a call?
my problem is that ppl hear in such eco thing and this is crazy everyone say they don't hear me good
Okay. Then I don't think our problems are related.

crackling earpiece

when I make a call, the earpiece makes a staticy popping noise. I turn the call volume down and it's still somewhat there but I can't help but think there's something wrong with the earpiece. Do this happen to anyone else?
Does it still do it if you uncheck voice privacy in the dialer settings? That would be my only suggestion.
I experience the same thing. I have to lower the volume to make it go away. I tested my earpiece on other phones (touch pro 2 and iphone 4s) and I don't experience the same static even at the highest level. I suspect that the lte is pushing higher frequencies that some headsets cannot handle. I tried different equalizer settings without any changes. I took a higher quality headset and the distortion goes away confirming my theory. I don't think some headsets can handle the full range of frequencies that the lte pushes out. Does anyone know of any mods that will alter the frequency more than the stock settings?
similar problem, but with playing videos... (at least with some of them)

that seems to have done it, will test it further but for right now thank!
having the same problem, constant ticking noise coming from the earpiece speaker when I make a call, and its only on my end. Tried the solutions mentioned above, still got the issue. No problems with bluetooth or using the speaker phone
I'm having the same issues, doesn't seem to happen on every call. But it only happens on my end where I hear the cracking noise. The person on the other end says I sound fine. Does anyone know I can do?
This is an EVO problem

I have the same problem... sometime it sounds ok, then some call sound like crap! Then I started testing it and found that it happens 100% of the time... just on one end of the phone. If you are having this problem, make a call... If it sounds good to you, ask the person on the other end of the phone how you sound! You will see that one of the two people will have bad call quality, making this a problem 100% of the time!

[Q] <E4GT> Mic Problem

Yes I did post this in the device specific forum, but no one seems to have any idea. But it has me very confused, So I thought I would bring it to the general community.
So I acquired a ET4G the other day from a friend who had dropped it in some water. He did an insurance claim so he has his new one and gave me this one to play with. Everything works fine except the mic and the notification light was stuck on.
I completely disassembled and cleaned the circuit board and contacts. Now the notification light works properly and the mic works when recording video.
There is no mic in skype, calls, searching, anything except video recording that I've tested so far.
Sooo, Does video recording use a separate mic , if not does anyone have any ideas?
It's running CM9 right now but shouldn't make a difference. I have already flashed it to stock and back to make sure it wasn't a software issue.
Any ideas would be appreciated

Mic record loud hissing noise independent of Rom [H850]

I have bought a used H850 that I can't return. Every time I record a video (haven't tested calling yet) I hear a loud hissing (with static crackling) on the recording later on. This happens on both Fulmics Rom and LineageOS, thus I think it is hardware related.
I applied the fix for the GPS from this video (open device and put folded paper under the board where the gps antennas are) and folded a paper to have three layers. Since I don't remember testing video before testing and fixing GPS (because it was broken), I don't know if that is related.
Anyone have an idea?
I also have on of those camera modules for the G5, which attaches to the lower end. I tested it, because it also contains a microphone. When I record with that module attached, the noise is still there, but muffled.
I removed the paper, but that did not get rid of the hissing sound.
So I tested calling and the noise is there, but stops a couple seconds into the call. I guess when the noise cancellation kicks in.
So I reverted back to stock using LG UP (Uppercut) and an older kdz file, then used to automatic update process to get the current rom.
And now the hissing is gone?!? It's great! But I bought this device to use with custom roms, especially LineageOS. So I will have to go back and see how that works out.
OK, now it gets weird. The first couple videos I recorded with the April update. Those were noise free. Then the auto updater applied the June update for the stock rom and the noise is back. On stock. If that is a software issue, how come I can't find anyone else with this problem? And if it's a hardware issue, why was it gone for a couple videos while I was on April?

[Elephone S8] Loudspeaker issue

Hello to all,
I got an Elephone S8 for my girlfriend and in general I think you get a lot of phone for the price!
One thing I noticed is that whenever you have a WhatsApp call and you turn on the Loudspeaker on the Elephone S8 there will be distortions in the audio.
It is not hearing an echo or something it is more of a static noise and squeaking that can be heard every few seconds (it is not constant).
Did anyone having that phone also experience that problem so far ?
Same thing here, but only with WhatsApp calls and WhatsApp video calls.
+1 same issue (+ with Viber)
Only with Video call and turned on Loudspeaker
Same Issue

Yeah my girlfriend recently bought this phone too, I found she had the same problem with Whatsapp, skype and google duo voice and video calls.
Same sort of noises, static, video quality was terrible and a squeaking microwave high pitched noise intermittently.
When we switched her wifi off and used her 4g it was better but still similar issues.
The phone is amazing but this is annoying, i hope there is a fix for it as it is quite an important feature.
Has anyone resolved this?
I had distortion and noise issues on speakerphone until I realised I had the phone at full volume. Reducing the volume a couple of notches got rid of the feedback and resulted in much better call quality.
Don't know if this will resolve your issue. Good luck!
