Recently got myself a LG G2. Only issue I'm having is the person I'm talking to during a call can barely hear me (muffled and quiet). It works fine in a normal call regardless of the voice enhancement/cancellation being on or off. Problem only occurs with speaker. Sound is the same whether I'm talking in to bottom microphone or the top microphone. Phone is not rooted
I updated the phone a couple weeks ago. I remember using speaker in call with out an issue when I first got the phone. I can't remember if I updated to Kitkat and had it working. Or if updating to Kitkat has caused the problem
Also, NO sound appears to be sent when using Viber with speaker 'on'. However, speaker 'off' works fine
Android 4.4.2
Kernel 3.4.0
Software Version D80220a-AME-XX
Thanks in advance

Hello everybody,
I'm sorry for opening that topic but i'm desperate now. I saw similar topics for that but i tried every written solution on that topics not working.
Last month i've rooted my i9500 first time and flashed CyanogenMod (4.4.2 Kitkat). There were few bugs on this ROM. For example Camera Problem, Low Mic issue etc.. After i used that ROM 2 days, i decided to change my ROM because of bugs. I changed 4-5 ROMs for i9500. ( Phoenix, CyanogenMod(New Version), MIUI etc... But the low mic issue was still there.
I tried flashing Stock Rom 4.3
Flashing Stock New Rom 4.4
Flashing stock Kernel and stock Radio
Flashing other ROMs...
I tried all of them. All problems gone except low mic issue. First I thought something wrong with my hardware but after that i noticed that the low mic issue is just running on Phone Calls. If i open speaker my voice is perfect but in normal call people barely hear me or don't hear me.
Voice recorder and Video Recording is perfectly record sound. The problem is occur only Phone Call without speaker.
So i need your help, how i can solve this low mic issue ?
Thanks for all.
try downloading AudioManager on play store and see if it helps. It could be a hardware problem you know.
cheers ~
I downloaded AudioManager but nothing changed. I guess the problem is not hardware because if i use speaker on phone calls my voice is perfect. Audio recording and video recording are also perfect.
No solutions ?
please help me about this. i tried everything i've read nothing changed.
You've probably got dirt in your microphone hole, locate it on the bottom of the device and use a dental pick or something to clear the blockage.
Perhaps you're covering the microphone hole when you hold up the phone to your ear?
I tried to clean it nothing changed. I'm holding same as i always do . I tried directly speak to mic hole. Nothing changed
Same Issue please help us
I Have same issues, im sure Hardware is working Fine, mic in low volume if using at phone call and record voice note. but in other apps like Audio Record, and Activate Speaker Phone mic is Working properly, S Voice, etc
I also upgrade my device GT-I9500 JB 4.3 with firmware for Russia I9500XXUFNB3_I9500SERFNB3_I9500XXUFNA6_HOME
After that , start my problem with S4 device and microphone NOT working level is so bad and low .... sound is very poor
If I use speaker option mic working good , also if I use bluetooth headset for communication sound work good , normal .
But have problem if I answering and try talk "normally " by microphone .
Today try with other 4.4.2 firmware like I9500XXUFNB7_I9500OLBFNB4
But unfortunately, there is still the problem with my S4 GT-I9500
My mic work good with JB 4.3 but this problem start when upgrade to 4.4.2
Best ,
Z.
can someone edit this..?
same here~
but can someone test or edit file default_gain.conf maybe it will solve our prob
Thanks

Hi, I'm writing to you to address a problem I have been having for a while now. When I speak on the phone and the speaker is off, the other person hears themself echo. It works fine when the speaker is on but when the speaker is on everyone hears your conversation.
and,
My friend has the same phone (LG G2 D802) as me and we were speaking on Viber and again without the speaker on it was echoing for the both of us. When we both turned on our speakers it started making a static like sound. Oddly enough when we turned off the speaker both the static sound and the echoing stopped. It was weird but i dont want to have to turn the speaker on off everytime and even when i do it doesnt work everytime.
My Device: LG G2 D802 (Android 4.4.2)
Same problem here, I think its common to all G2s.
I haven't tried it on a custom Rom yet cause I've been running stock mostly, but I'm betting its software.
Same problem here
Hello, its not just Viber its almost all of the VoIP clients. I have serious doubts about "its software issue" well I have tried almost 4 different roms. from stock 4.2.2 to CM 11. Nothing seems to work. I wonder its the chip. i don't know i am not expert.
if you have any VoIP working plz share. thanks.

Hello,
I have a galaxy S4 (canadian version) and have only been having troubles with it within the last couple days. I do develop so I'm not new when it comes to phones but this issue has me at a lose.
Problem:
When I make or receive a phone call there is absolutely no audio on my end, I cannot hear the dial tones or the other person's voice. The only thing I can here is the call connect and disconnect beeps. The person on the other end hears a very loud buzzing/white noise. This noise becomes intermittent slightly when I speak into the problematic device.
It is only when making/receiving a phone call that the audio does not work. All speakers are functioning in all other apps (music player/skype etc.) the mic is also working without a problem when used for other apps.
When the problem first started I was running 4.2.2 firmware. I was making a phone call when the audio cut out unexpectedly having assumed it was a dropped call I made an other attempt but there was no sound at all. I restarted the device and that very briefly fixed the issue. However every time since restarting the phone has done nothing.
WiFi is working fine as well.
Attempts at Solutions:
Restarting the device (with headphone connected and without)
Factory resetting the device (with headphone connected and without)
Flashing updated (and older) stock firmware on to the device
Flashing custom ROMs on to the device
Dialer apps
SoundAbout app
Making calls with headphone connected / speaker phone
All settings have been checked to ensure in call volume has not been disabled
About Device:Currently running: Gummy version M1.02-25-14-NIGHTLY (Please note that when the phone first started messing up I was running stock 4.2.2 and there was no audio during a call between either phone. The Gummy ROM has made some improvement)
Current android version: 4.4.2
Phone Model #: SGH-I337M (Canadian S4)
Baseband version: I337MVLUAMDJ
Any help is appreciated!
Thank-you
I'm having a similar issue with my ATT SGS4. It started happening randomly...the person on the other end hears beeps and I hear nothing. Speaker/headset with mic don't work either. Only thing that works is Bluetooth oddly enough...but as soon as I switch to speaker, it goes back to not working.
A reboot fixes it temporarily, but then it comes back randomly..either right away or later on in the day.
If Bluetooth works fine for voice calls then I would guess that it's a physical hardware issue. Perhaps the ADC / DAC for onboard mic and headset is malfunctioning?
For Bluetooth I would also guess that A to D conversion happens within the Bluetooth chip which seems to be working fine.
It would be nice to see a schematic.
Edit: I found a block diagram of the circuit. and this link https://www.ifixit.com/Teardown/Samsung+Galaxy+S4+Teardown/13947
So it looks like the audio codec goes straight into the modem but the Bluetooth goes through the Snapdragon CPU before going to the modem. Based on this my original assumption seems to be correct and your mic codec is malfunctioning or there is a physical connection problem.
Hope this helps in any way.
Does this explain why a restart fixes the issue though? If it were solely a connection/hardware issue, a restart wouldn't do crap (unless it re-initializes the circuit and then something causes it to go derp again).

Same thing happened to me, the incall audio chip as gone bad. I had to buy a S4 with a cracked screen off craigslist and swap mother boards and the phone works perfectly now.
SOLUTION: Samsung Galaxy S4 I337 no audio sound during phone call.
SOLUTION: Samsung Galaxy S4 I337 no audio sound during phone call.
For me it was a bad SIM Card Reader or Module IF. But it could be a bad SIM card so try a new SIM before doing this repair or at least take it out and in.
My Service Repair Statement said it replaced two things:
Part Number Description
GH59-13279A Unit-SIM SD SOCKET; SGH-I377, 10-0013-0278
GH59-13111A MODULE-IF SUB FPCB(SGH-I337);SGH-I337,10
Called 800-726-7864 told them what the symptoms were and that the support line said it was the SIM Card Reader and they gave me a quote of $70.36 and seemed confident that the phone would be fixed. Sent to Samsung Repair Facility in Texas, total cost $70.36, and was without it for 9 days. It’s been working for 2 weeks now with no problems.
First I took it to an AT&T Service Center and all they really did was try a new SIM Card, next called Samsung Service 888-987-4357 and went thru a series of tests and they said it was a bad SIM card reader and gave me the repair center number.
Symptoms:
No audio / sound during a phone call on either side (caller or receiver)
Call connects everything is working, just no sound.
Sound for all other functions and apps works (music, voice recording, video audio).
You can tell it is going to happen when you make a call and you don’t hear any ringing just a click sound then nothing. If you hear ringing then the call will work.
Rebooting usual works for a call or two. Messing with some settings may get it to work for a period of time. But for me none of any of the other suggested fixes worked except rebooting and turning airplane mode on and off but it only fixed it for awhile.
I have used the phone for 1.5 years and never had a single hardware problem, didn’t have it heavily loaded (RAM or Memory). It just started one day out of the blue and drove me crazy.

i have the same issue no audio in calls and i rehot the audio codec ic wcd9310 and that worked completely
Hello,
Can someone please heeeelp me, I have a Samsung s4 I9505 that I bought with a problem:
When I call someone I can hear perfectly but the other person hears a crackling sound and almost no sound but ONLY IN NORMAL CALL mode, when in SPEAKER it seems to work just fine, also with the headset the crackling sound persists.
The problem also persists in any app like viber, watsapp, voice recorder..
Things I have tried:
Restarting, factory reset
Different firmware like Kitkat 4.4 and Lollipop 5.01
Changing the charge dock with the microphone
Is there another microphone that is activated while on speaker mode than on normal call or what is the difference between normal call and speaker mode?
Hi guys
I've had the Note 4 for a while but only had an issue I think after the marshmallow update. The microphone doesn't seem to pick up any sound: tried to record a voice memo and it's blank. WhatsApp calls, the other person can't hear anything, Snapchat doesn't record any sound. Weird thing is that when I call someone with the normal dialler it picks up sound fine. A restart fixes the mic issues and works well, but after charging the phone the mic stops working again. Any solutions?
Unlocked, Not rooted, Knox tripped though, & running android 6.0.1
I have the exact same issue when I moved to the German 6.0.1 N910FXXS1DPE6 ...
Restarting fixes it but is a pain in the ass
