[BUG?] Microphone record volume level too hight causes noise in calls

Hey there i don't mind if anybody had this recognized too... but the Microphone level is quite too high!
to me as non dev it seems that the microphone on normal (not loudspeaker calls) is sensitiv as in loudspeakercalls it should be...
because that we have the heavy noises when calling! (not a big problem when using the loudspeaker mode because than you didn't talk directly to the mic and the voice didn'ts gets overpitched on the other side!
just try to call your self from a nother phone and then enable the loudspeaker mode... you didn't hear changes in mic. level ...
you want to report
maybe its a small and easy thing to change this?!

write kernel driver to control appropriate HW!!
HD2 as sensor for reduction noise,
it need implemented on Linux Kernel
i think the mic is just to sensitiv in normal calling mode (non loudspeaker mode)
... no need for the noise reduction sensor (are you sure that there a second mic to reduce noise..)
But i found a solution, just use the Headphones ... no Noise on the other side

But this is a trick and not a solution for everyday use. I think the Mic Level is to high, too. I think that is the problem that every one have with "echos" maybe?! Anybody can fix this to try it out?

[Q] Call problem with Sony Headphones

Hey all,
As I didn't like Samsung earbuds, I use my Sony MDR-J10 Ear Clip Headphones. But in calls, I can't hear the other person's voice because it's too low. And it's really annoying every time I receive a call and I'm listening to music, to unplug the headphones and after the call to replug them . Any idea how to solve this problem?
Just in case, I use Kyrillos v6 with G3MOD v1.3.2 Ultimate kernel
Thanks in advance!
Check EQ settings of headphones.. make it to default or try tweaking using tricks given in thread of EQ settings.. hope this would help.. i totally understand ur situation

Thanks. I was just testing this (btw, I can't access to audio menu. It must be blocked in jpq or something), and I tried to make a call. I realized that the the person's voice is not being 'bypassed' to the headphones (in other words, it's still being 'played' in G3's front speaker (just like it would do if there was no headphones connected. But before and after the call, all system/music sounds are played on the headphones :S).
Hope I didn't messed the text up a lot xD
Edit: When I try with Samsung earbuds, it ok. I can listen to the other person perfectly. Any idea to make it work with the Sony ones? I really hate earbuds xD

External Speaker Voice Calls Quality

Hi everyone, when i am talking with someone and i turn on the speaker the voice call quality is kind of bad, i hear crackling and poping sounds. Now when i play a movie or music through the speaker its fine so its just the voice calls..i am wondering if this is normal and if anyone else is experiencing this at full volume. I am using the Lightening rom if that matters.
Sent from my GT-I9100 using XDA App
Can please someone test this? It will really help me. Just switch to speaker while on a call and max the volume to see if you hear distortion. Thank you in advance.

[Q] Noise cancellation fails with earphones

Normally (phone speaker & mic) I can hear people pretty well and they can hear me pretty well.
When I use earphones (that don't have a mic) the person at the other end can't hear me at all!
For a while I thought that it might have to do with how I was holding the phone while speaking - since I was using the phone's microphone to talk and my own earphones to listen I thought that that might be the reason that people couldn't hear me.
I did some test calls yesterday and that doesn't seem to be the cause.
I did notice that at the beginning of the call, I can hear sounds from my environment (cars honking, people talking etc) coming in over my headphones so I now suspect that the noise cancellation software isn't working properly when using earphones.
Has anyone experienced this issue?
Any fixes?
I tried searching both xda and googel but couldn't find anything that sounded relevant.
I've also tested this on multiple roms and with clean install of pure android, no differences.
Thanks!
Edit: I didn't read well .. Try to stick to head phones who has a microphone built in I cant think about another solution ..
Have u tried using earphones who had a microphone built in . try that first and post results ...
P.s I had this problem too before . hope I helped you

I've tried just about all possible options - the problem doesn't seem to occur when using a bt headset or wired headset with mic - in those situation the noise cancellation software seems to disable itself, which isn't ideal but is much better than it feeding the noise back into my earphones.
i have been using a stereo bt set for a while because it gives me the best overall experience but I would really like to go back to my wired earphones (shure e2c's) as the difference in audio quality is huge, but having to unplug the earphones everytime I recieve a call is rly annoying.
i was hoping that there would be a fix that I had somehow missed....
thanks anyways

[Q] Earpiece distortion

HI there guys.
Brand new to this forum.
I've searched for days and I'm unable to find a solution.
I'm experiencing a crackling or a distortion on phone calls at certain volumes. I noticed it with certain pitches in peoples voices it would cause a vibration in the ear speaker and some distortion in the sound. Kind of like the speaker is being over driven or has too much power going to it. It usually goes away if I turn the volume almost all the way down, but this is obviously not a practical option since I'm not always making phone calls in a dead silent room. The speaker phone works fine. This only happens when I'm using the earpiece. Is this normal? Is it related to the camera autofocus sensor rattle? Are the sound vibrations from a person's voice enough to set off the rattle? It's really annoying as I tend to make phone calls a lot and I don't like using speaker phone or a headset. Does anyone else have this problem?
From what I can tell, it happened and was normal in the S4. (http://forum.xda-developers.com/showthread.php?t=2280930).
Please help. Im deciding if i need to return it.

It's too bad that you didn't describe it in more detail.. i.e. give us steps to replicate it. A recording of the distortion would have been helpful too. I haven't noticed what you describe but it sounds like the gain or auto gain is too high and your earpiece speaker is being overdriven.
There is a gain setting in the service mode menu but first you need to distinguish an app issue or possibly damaged speaker before messing around in the hidden settings. See if you can find an audio app that will give you a wider adjustment range for your system volume and gain.,

Thank you for the reply.
If you go into the service menu, the go into the low frequency test. At 100hz and 200 hz there is a little bit of buzz in the headset reciever unless you really push it against your face (which i assume kind of tightens the spaces in the plastic and prevents whatever vibration in the speaker is occuring).
Hmm.. the vibration is akin to as if you were speaking into some cellophane wrap; like some film (maybe for waterproofing) is covering the speaker.
Oh. It's also worth noting that I cannot replicate the issue on Skype or Viber. Those sound crystal clear.
Bump. Anyone?
