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.

Not sure what numbers I should give you so Im going to give you everything.
Current firmware version : PDA:LPD / PHONE:LPB / CSC:LPD (TMU)
Model number : GT-I9100
Android version : 4.0.3
Baseband version : I9100BVLPB
Kernel version : [email protected]#3
Build number : IM74K.BVLPD
The phone is a UK SGS II, has not been rooted. It is running the official T-Mobile ICS Rom.
A couple of days ago I noticed an intermittent but significant loss of data. I could be in the same place for hours and it would happen, I could be on the move and it would happen. I decided to use Samsung Kies to see of there was a firmware upgrade and would reset the phone. This was done yesterday.
Today I have had lots of issues. Data again will come and go at will, the data icon in the taskbar will disappear intermittently. I have also lost SOME audio. By some I mean the following:
No audio from media via the speaker, either stored on the phone or over the internet. Tried BBC iPlayer, Youtube, Samsung Music Hub. Audio on the phone played through headphones was fine.
Ringtones work fine, but when I answer a call there is nothing from the earpiece. Switch to speaker and I can hear the caller.
Notification tones seem to be working fine.
No keypad tones from phone screen. I have checked to make sure that keypad tones is activated.
No 'system sounds'.
I have been into the menu for volumes (Menu, Settings, Sound, Volumes) and:
if I move the media slider I hear nothing (though I do get the 'harmful' warning when the slider is pushed all the way to the right
if I move the Ringtone Slider I can hear the ringtone playing back in relation to the slider position
if I move the Notification slider I can hear the notification tone playing back in relation to the slider position
if I move the System slider I hear nothing at all
The odd thing is that earlier in the day it was working, then part way through the afternoon I got nothing.
I have spoken to T-Mobile who were less than useless. First of all they said that T-Mobile did not recommend upgrading from Gingerbread to ICS, this is despite the rom in the phone being the official T-Mobile branded ICS rom that they released and I upgraded to through Samsung Kies. Their only answer was to take it back to the shop and they would send it away to be downgraded back to Gingerbread.
Is this likely to solve the problem? I am sceptical. The phone has been running fine on ICS for maybe a month, or since the official ICS rom was released anyway, its only in the past couple of days that I have had a problem.
I cant see it being a hardware issue as the speaker is obviously working for me to hear ringtones and be able to hold a phone call on speakerphone (though that doesnt rule out a hardware issue with the earpiece). I was originally thinking more a software conflict somewhere, so thats why I decided to try a reset and firmware upgrade. I have run it with just a couple of apps from Google Play, Facebook and Tunein Radio to be precise and it still had the same issues, and then tried it without installing anything from Google Play, just transferring a single music file from my PC to the phone and that didnt work either. The track played, but there was no audio to hear via the speaker. If I connect headphones to the 3.5mm socket I can hear the audio perfectly fine.
Im hoping someone has some input on this before I go to the store with the phone tomorrow. Has anyone experienced similar issues?
Cheers in advance
Ive been looking a bit further into this and Im wondering if the headphone socket may be to blame?
Ive had a couple of people take a look at the headphone socket, and the general consensus is that it doesnt look right. One thinks that maybe a pin is bent and the bottom of the socket just looks 'wrong'. Thoughts?
Randomly when I make calls or receive calls I have no sound. I can't hear them and they can't hear me. Rebooting the phone will fix the issue for a short while. I have been able to reproduce this by connecting to my cars blue tooth and making a call. The 1st call works however all calls after the first call I have no sound again. When the phone in the no sound state (Phone Call) Bluetooth media still works just no sound while in a call. The speakers work because I can play music and the mic still works because I can still record sound. This issue seams to be related to the phone app its self???
My phone is a Samsung S4 (AT&T) with Android 4.4.2 (Rooted via Towelroot) with SuperSU by chain-fire installed.
Here is some of the trouble shooting I have already done.
1. Factory Rest the Phone via Stock Recovery (Still can reproduce the issue)
2. Played around with various settings i.e. Google Now Bluetooth options. Un-paired all Bluetooth devices and then re-paired one to try (Still having same issue)
3. Cleaned out all app cache (Still having same issue)
4. Re-installed pre-installed apps that I removed once rooted.
Long story short, this one has be baffled. The only thing that fixes the issue is re-starting the phone.
Thanks in advance for any assistance

Same Problem Here, I may have figured it out:
After I rooted I used some apps to auto kill some running, supposedly non-essential apps. This caused my phone call problems, same exact issue as you're having. A reboot fixed it for me as well. I will let you know if it happens again without closing any apps.......
Hi,
I realize this will sound like a strange issue, but I can reproduce it so it certainly exists.
I have an LG G3 running Android 4.4.2 on Verizon. I just bought it back in Jan '15, and the phone has been working great with no issues. I use my car's built in bluetooth connectivity to place and receive calls while driving and have had no issues doing so.
A few days ago (week of 3/9/15), I acquired a used LG G watch from a friend at work. It's in good shape; he only had it a few months, and it's working well. It connects to my phone, and I can use it to txt, place calls, etc. It's running software version 5.0.2.
I am experiencing an issue for which I cannot find the root cause. My issue is that, when I'm in my car, and both the car and the watch are connected to the phone via blue tooth, and I place or receive a call, folks on the other end cannot hear me speak. I tried it with my wife's cell phone, and can reproduce it every call. My voice is barely audible, yet bluetooth is connected to the car and I can hear the other person's voice just fine over my car speakers. As this is happening, if I pick up my phone and switch the call to the handset from bluetooth, the problem goes away and I can take the call on the handset. But as soon as I put it back to bluetooth, the problem returns. Once this happens, if I hang up and try to call the person back using either bluetooth OR the handset, the voice problem returns and I cannot be heard speaking. I tried putting my mouth up to the watch and the phone thinking maybe it was trying to use another microphone, but I still sounded muffled and far away while I was testing this with my wife's phone.
I have checked all my settings in Android Wear, my phone settings for volume as well as call settings...I cannot find anything obvious. I've googled the issue, but there is little to no information regarding this problem.
Can anyone suggest something to help fix this? I really like the G watch, and I would like to get it to work so I can enjoy it. You would think that the G3 and G watch would play nice since they are both LG!
Thanks for any help,
Nick
Having the same issue....sort of...
First, allow me to apologize for any improper formatting or if I've tendered my reply in the wrong way.
I've literally never replied on a message board in my life. Ugh, I know. How, right? Moving on...
I have an issue very similar to the one you're having, only in place of the car, put a Plantronics WalMart headset and change the G3 for it's predecessor. I notice that people call me when my watch is connected to my phone. When I answer, they claim to not be able to hear or understand what I am saying. The problem persists even if I disconnect my headset and use the G2 in either handset or speakerphone mode. The only fix I've found is to restart the phone and return the call. Even then, if the watch is still connected, only the first call can be completed with no "interference".
I've attempted to update the software and firmware to my G2, with no success. I have no idea why this issue occurs.
Also, is probably noteworthy that regardless of whatever Bluetooth device I am connected, very very often during a call, my caller's voice will shift into "speakerphone" mode without being instructed to do so. I have to open the call screen, turn off the BT, then select it again to turn it back on. The call returns to the headset, but doesn't stay there in most cases. Sometimes I have to do this 5 - 7 times a call. Other times, it remains connected as it's supposed to. Again, I can find no reason why this happens, but it's been an issue for MONTHS with my G2. And it doesn't matter what headset I am using, it just "drops" the sound to my speaker phone, but still says that it remains connected to the headset.
It's a Sprint LG G2, if that matters at all.

Have you tried going into android settings for voice input and allowing recording using Bluetooth mic?
Hello gals and guys, you are my last hope.
I have a Galyxy S7 Edge G935F bought in Germany with no sim lock, i got it with G935FXXU1APAW, updated to G395FXXU1APC8. Yesterday i rooted it with CF-Auto-Root-hero2lte-hero2ltexx-smg935f based on XXU1APBF. I still have stock recovery.
The Problem:
Sometimes, while sleeping, the phone disables all sound.
This happens mostly while recharging, but it happened also while simply sleeping and not recharging. It is not reliably reproducable, sometimes the phone works for 2 or 3 days without the error occurring. Which makes the error very hard to find of course.
Sound off means: No media output is working (games, video, music), notifications are not sounding only vibrate, the phone doesn't ring when someone calls, just vibrates. No calls and notifications means, this is very severe.
When i plug in earphones or headphones, there is also no sound on the headphones. Putting in and pulling out the headphones does not reactivate the sound, so it seems not to be a problem with the headphone jack. The jack is very loose, though, doesnt hold the headphones strongly; but thats another problem.
The sound can be reactivated by the following:
- rebooting
- calling someone (i used to call my provider) or getting called (the first call gets lost, but when i get a second call, it works again)
- i installed an app called SoundAbout, which lets me route the sound to different outputs. I must first route media output to "earpiece" (the small loudspeaker you hold on your ear during calls) and then route the media back to "Speaker". Only this combination reactivates the sound again. Just activating "Speaker" or any other combination like for example first "Wired Phones" and then "Speaker" does not work. It must be "earpiece" and then "Speaker".
What i tried, without success:
- deleted all bluetooth devices
- disabled bluetooth
- enabled "prevent USB audio routing" in dev options
- uninstalled all kinds of apps having to do with sound or lockscreen
- played with all kinds of settings having to do with sound or lockscreen
I searched everywhere. A call to Samsung was not very helpful either. I might have to try a factory reset after all, but even if its good at factory, i still won't know the culprit.
But since the problem can be solved via software, i suspect it is software related or is at least diagnoseable via software.
Of course, it would be insanely awesome when someone could just present me the solution, but i would do all the debugging myself, if i only could.
I am a developer myself, but only on windows. My experiences on linux don't go much further than doing an "ls -la" on commandline and i am a total noob on android. I will not be afraid of using a terminal or adb, as long as i am guided a bit.
I hope, somebody can point me out how to diagnose and this thing.
Can one diagnose the current state of audio routing ? Can i manipulate it via commandline ? Are there other relevant components which i need to query ?
Could i write a script that pulls those queries every minute or so ?
And finally, if the wrong settings are found, are there log files which can point out who messed with those settings. Which apps would you recommend for those actions ?
Thanks to everyone in advance ...
Correction
just getting called doesn't fix anything. Only when i accept the call it gets fixed and then the next call rings again, of course. So this means, while the bug is active, i miss all calls.
Hi all,
I've owned my S4 for a year an a half and out of nowhere started experiencing a huge issue today.
I have no audio whatsoever - earpiece or mic - when making a cellular call. I dial, and the call goes through (the other party receives the cal), but I have no audio. Even when plugging in a headset, still no audio. Incoming calls exhibit the same problem.
When connected to bluetooth, I do have audio + mic through the bluetooth device. As soon as I disable bluetooth, the issue returns.
All other apps/audio work fine - VOIP, texting, data... I can make Hangouts calls and the earpiece and microphone work.
I've rebooted the phone; that worked for a few minutes then the problem came back. I also did a battery + microSD + sim card pull, that fixed the issue for probably 30 minutes, then it returned.
I also flashed a new rom just to see if it would fix it - it didn't. Removed microSD, no fix.
I'm running Stock GPE 5.1 and have been for many months with no issues whatsoever, then this creeps up out of nowhere today. I've done some searches and other people have had the issue but I can't seem to find a definitive fix. Some report faulty SIM reader, but I have no problems otherwise with my SIM, and BT calls work so that would seem to rule that out?
Has anyone had this issue and/or fixed it?
Best,
-Dirk
OK so it appears to be hardware!
While making a test call, I took the back cover off and moved my finger around the upper area of the phone - near the SIM card slot - and applied various amounts of pressure. The in-call audio returned! However if I jostle the phone a bit, I lose audio. So some sort of connection in that area is loose or fraying or something.
Has anyone else had a similar issue? Perhaps tightening things would fix?
