No sound on voice calls

As the title says, I have no sound from the earphone during voice call. Also, when trying to call somebody, it shows on their phone but they can't hear anything from me.
The problem appeared suddenly, without any intervention from me.
I've tried, without any luck, the following:
- battery pull (several times, to be exact);
- SIM change (also switching operators);
- nandroid backup + data wipe + restore;
- I was running the SAFE 1.37 ROM and had it rooted. I flashed to "not so safe" 1.37 ROM from shipped roms, still nothing.
EVERYTHING else works perfectly on the phone: SMS, mobile data, etc etc.
I'm quite desperate at the moment as I feel I've tried everything I know and I'm thinking it might be a hardware problem that will require me to go back to the seller with it.
Has anyone else experienced this and solved it? I've tried searching on google and here on the forums, couldn't find anything.
Thanks for all your help.

Well I did go with it to the service center.
Should take them no more than 15 days to tell me something...hope it doesn't take that long, though....
In the meantime, if anybody knows anything about this problem, please do post...
It may not help me but it may help others.

Got it back from the service centre today.
Apparently it was just a hardware problem : they've replaced the earphone.
Everything back to normal now, topic can be closed.

[Q] No Voice (incoming or outgoing) on Nexus 4?

OK, having a huge problem with my Nexus 4. I'm still running stock kernel/ROM (although I am rooted) and everything about the phone works great EXCEPT for the phone itself! What I mean by this is: everything works (data, texts, tethering, et cetera), I can make and receive calls... but on those calls, there is no sound in *either direction*; when on a call, the mic doesn't pick up my voice, nor does the speaker relay the caller's voice. WTF?
My in-call volume is set to maximum, as checked via Power Toggles.
I've also noticed that the phone has a hell of a time hanging up after a call. For instance, I make a call on the N4 (again, no voice/sound during said call), and when I go to hang up the phone screen simply says "hanging up" and hangs like that for almost a minute. If I try to make another call after that, I get an error "Call Not Sent".
Any ideas how I might be able to track this problem down?
I should also mention that I don't know how long this problem has been present. I really don't use voice calling very much. When I tested the phone when I first received it, I simply made a call from it and to it from our land line and made sure it rang... I didn't think that there might be any issues with the call itself!

I have a brand new N4 that I just rooted using WugFresh toolkit and I see now that I can't hear anything during a call nor can the other person hear anything.
I've tried downgrading to .33 and .27. Also reflashing .48 with no success.
What should I do?

If you are experiencing the same problem I was, it wasn't fixable. I tried everything (reflashing stock, trying different ROMs, etc.)... and apparently it was just a hardware defect. I contacted Google and after explaining the issue (which they hadn't heard about at that point) they shipped me a new phone, which works perfectly.
I would highly recommend not wasting your time trying to diagnose the issue further and get in touch with Google about getting a replacement.
Cheers,
Matt

Thanks a lot for getting back to me. I contacted them and they already sent a replacement unit.
I found a thread on Google forums with six pages of people complaining about this. Apparently is not an isolated problem. Half of the people have the problem after updating to 4.2.2 and the other half (last pages) are all with new phones (4.2.2).

jumped in been a while since I had a play with LS - first impression love the splash screen :good:

Same problem, no warranty
Lucky you guys who were still under warranty. My Nexus 4 is 2 years old now and I just got this problem. It seems to be software related. The mic and speaker works for anything else other than placing phone calls. Furthermore, even if I plug a standard headset thought the 3.5mm jack, still no luck. The same with bluetooth headset.
It's interesting that when this problem started I would be able to place or receive a call once per reboot, i.e., after rebooting, the speaker and mic would work on the first call, but not for the second call unless I reboot the phone. Now I doesn't work even after reboot.
Gargabe?

Hi,
I have exactly same problem with sound during call. I'm using CM11. It doesn't matter if it is nightly or snapshot, simply there is no sound during call. Everything except calling works fine - music, ringing etc.
Restart didn't fork for me and also deleting application data has no effect. I've found only one solution - factory reset approximately each week. It is obvious that this is only workaround and not real solution.
I don't know if it is HW or SW issue. Strange think is that factory reset helps.
Any ideas are welcome. Thank you in advance.

I have the same problem.
Reverting to stock solved the issue form me until a fix for CM11 will be found.
BTW there is a bug report for CM11.
I can't post links but the code is CYAN-5728 on the CM bugtracking system.

The issue is with Google Play Services. more specifically the checkin service within it.
(this is from the CM bugtracking system , code: CYAN-5728, as stated by pupillo)
download/install the app "DisableService" from the play store. (must be rooted)
under the [System] tab, browse to "Google Play Services", tap it, then browse to "checkinservice", uncheck. (it will prompt for superuser, allow)
restart phone
try placing/receiving a call

none of u guys spent even 1 second to check this forums for answer. there have been at least 2-3 threads about this issue, all of them containing/linking to the fix.

[Q] No sound when calling (ring and voice)

Hi guys,
I have a Canadian sgh-i337 (Bell) and when I call someone I cannot hear the ring, the other person and that person cannot hear me. The call is connecting and all. This problem started when I flashed a Rom of the GT-i9505. I am on the new bootloader (MK6).
What I have tried or checked:
- Battery pull;
- Clear cache/Factory Reset;
- In call volume;
- Headphones (same problem);
- Speaker (same problem);
- Flash most recent modem (MK6);
- Odin stock Bell firmware;
- Check if receiver is working with *#0*# (It is working perfectly)
The problem happens for 90% of call I make or receive. For the other 10% the problem occurs after 1-2 minutes of talking.
Weird thing is when I flash the MK6 modem or Odin stock Bell rom it is working for about 10 minutes and it starts doing the same thing.
Been trying to find the problem for 1 week... I read alot before posting here and a small amount of people on other forums have the same problem but no fix for now...
I am thinking that it is an hardware problem but I don't have another phone so I want to try anything before return it to samsung for repair.
Your help is very appreciated,
Nicolas

The problem occurs less when I call from my car's bluetooth. I tried a custom kernel and rom with no success.

Bump, no one?

Got my phone back from samsung
Hi, just had the phone back from Samsung.
They wanted to charge me 300$ to change the motherboard because I have Know 0x1 and the warranty is void!
I'll just buy an used one and do the work myself.

[Q] I9505 problem BIOS nothings working

Who can help me. I am an total noob with this but installing a kernel or firmware (odin) works,
My I9505 was acting weird. The sound was gone and it was very slow. Some one looked at it and said that the 'bios' was gone. Well. the hardware was all good.
Now i want to reinstallal the whole thing. Soooo everything so it works again . Tryed diverend kinds of firmware and kernels but that doesnt work. Cam stil dont work. Awefull slow and no sound.
So is it scrapmetal or can some one help?

It is like this User_111 say's. Plz help us :S
Hi guys,
during last weeks, I couldn't get a second incoming call while I was talking. The phone didn't give any sign, that I had another call, the caller heard my line was busy. I had some overheating problems, but it's usual with S4. I've always battled with battery, but yesterday battery dropped by 70% after a two hour call. The CPU was working all the time, it also got overheated. I decided to flash the latest UGNG8 modem with Odin (it always drained too much during calls). After this the phone became ****ED UP BIG TIME!
- The phone's audio system has completely malfunctioned. I don't even have sound on boot. Somehow the camera also became defective.
In "quick test mode" melody, speaker, and camera won't work (warning camera failed).
- The Phone application is also totally ****ed up. When I start it, it is very laggy. I can't initiate calls with it (it starts the process, but freezes). When I have an incoming call, itt vibrates, but it has a black screen, I can't answer it.
- Yesterday I couldn't even use internet, today it works perfectly.
- When I unlock the phone it sometimes seems as it would freeze, but after half a minute it unlocks (with lags), sometimes it unlocks fluently.
- It won't connect to wifi network.
- Screen rotation doesn't work in Gallery, but it works in Gmail app (though it vas very laggy and it also froze for a while).
So other than these problems, it works like a charm . I can play chess, use Google maps, and any other apps. App drawer is fluent.
I wiped, reseted everything I could. I reflashed the older UGNG2 modem. Reinstalled Phoenix ROM two times, after that, I restored the original 4.2.2 software from my CWM backup. But all problems are still here.
It seems like a hardware problem to me. So the only thing I can do, is to take it to a service center? I don't have warranty, if they have to exchange the motherboard it will cost like a new phone (((. My problem looks similar to DarkEagle99's.
And what could have gone wrong? I don't think that flashing modem.bin and NON-HLOS.bin could ruin the hardware like this. So, what do you think?
Any opinions, suggestions? If there is no solution, I will have to take it to repair on Monday ((.

Camera failed sounds like a hardware issue....take it to a repair center...I hope your warranty is still good

Need Opinions And Thoughts Please

Ok ive been pulling my hair out for a while with this problem so im really hoping you guys can give me some answers or suggestions to help me fix it My Girlfriend has the Galaxy S5 SM-G900V. Baseband version G900VVRU2BOG5 So rooting or custom ROMS is out of the question so that leaves me with trying to diagnose and eliminate this problem without a easy way out.
Ok the problem is once she updated the phone to lollipop she had all the common problems that come with it over time i have slowly eliminated them with factory resets and cache cleaning and such although i have one problem that not even verizon can figure out. The phone itself with occassionally and randomly just refuse to make or receive calls its a very odd problem because the phone will send and receive sms and mms just fine when this happens but when we try to dial out it just sits at dialing and never connects, when calls are dialed into the phone it will ring 5 times or so then go to voice mail or just go straight to voicemail altogether without ever ringing the s5 shows no sign of anyone ever trying to call at all no ringing no records nothing. Once in a blue moon it will ring 4 times on the dial in and then the s5 will start ringing around the 5th ring which is extremely long time IMO. This happens very randomly and in all different locations i have disabled call blocking and auto reject i have tried safe mode to only experience the same problems, i have factory reset several times. Verizon opened a ticket with there tier 2 techs and network development team to check out the issue they tell us everything is completely fine and theres nothing they can see wrong. But they do not deny the problem is there they just cant explain it. Now get this, This is the second phone that has done this to her Ther first one had the same problem and was warranty claimed this is the second phone and same exact issues. Im not sure what else i can do i am a very tech savy person and this one has got me stumped the only thing i can see thats odd for me is the phone has 3 Phone services running in the background But I believe this may have something to do with the Touchwiz Easy Or Regular Home UI althought im not sure why it would use seperate apps. Anyway any input would be helpful Thanks
