[Galaxy S III Q&A, Help & Troubleshooting] xiaotiantian:
I have read all the post above.

Maybe I think the problem appear above may divice to two kinds.

One is no audio on calling, but the people can hear your voice.

The other is no audion on calling ,the signal drop.

Unfortunally my phone problem is the first one.

For the fist one ,I think maybe is a hardware ,sofware,or rom problem I dont know.

But sometimes I reboot it still no audion on calling and even no sounds when playing music.

So , I think it is a software or rom problem likely.

Sometimes I reboot my phone all problems gone, only need three times or less reboot.

If reboot doesn't help , I don't know what to do.

For the other Problem I think it is a hardware problem. But I have not occur, so I am not sure.

by the way

my phone is samsung note2 , rom is CM10.1 unofficial rom.

May the message help to u all.

Using CyanogenMod Nightly on my SGS3 I noticed that sometimes my speaker doesn't work during a call. Whoever is calling me can hear me but I can't hear a thing.Wipe helps but only for a while.

Surprise, Surprise... My GT-I9300 is from Germany! :(

Since the device is not intended for Latin American market its warranty was already void since I bought it at a local store in my country (Venezuela)...

The device failed almost a week before reaching warranty expiration date with the local store but since I reported the device directly to Samsung Support Center and expended that week trying to get the device reapired under warranty, the local store refuses to repair it under warranty and wants to charge me because warranty expired days ago....!!!!!!

So, back to my old iphone!!!

Possible Fix

Hello, I'm new to the forum but I've had the same problem on my S3 and i found a 100% fix for it.

Problem:

No sound during most calls, sudden loss of signal, sudden loss of sound during call etc.

I have tried so many things ie: flashing, restarting, formatting, modems, radios...nothing worked.

I was about to give up when I for some reason did 2 things that fixed the issue so i advise trying both IN THE SAME ORDER:

1) Take another phone that is working and that contains another working sim card (I used another galaxy s3; not tested with another brand). Swap the sim cars from and into both phones.

Make a minimum of 1 call with both phones containing the swapped sim cards and answer the phones. Make sure your call is successful with the new sim cards and answer.

When you are done swap back the sim cards into their original phones and try calling again.

2) Go to Settings ===> More Settings ===> Mobile Networks

a) Change your network mode

b) Change your network operator

c) Try every combination of both changes

d) Every time you make a change try calling someone

c) Finally change back the Network Operator to automatic

e) Change the network mode to the one that works (Normally only 1 works depending on the country and operator)

My phone worked after I did that. Hopefully it will work for you; it took me about 10 hours to figure it out since I noticed it clearly wasn't a hardware issue. My guess is that it probably happens if you changed operators or the region of your residency (also if you bought an already used phone).

[Galaxy S III Q&A, Help & Troubleshooting] Axathoth:
Hi,

I am facing the same issue :

Sound in calls mostly does not work

When it doesn't I cannot hear the person at the other end and neither can they hear me.

The call disconnects (on its own) with an out of network area message.

Also, randomly the sound works as it should and stops working again after some calls.

Tested the mic, receiver and speaker, all work.

I have been on the stock rom (recieved an update I9300XXEMH4 a week back) for the past 4-5 months.

This is happening since yesterday.

Is the solution given by Psykologikal the only way out or can something be done on the software side?

I am asking this because someone reported that even after getting the motherboard replaced, the problem came back.

Please help.

Hardware Fix

After trying a ton of different ROMS and modems, I attempted the hardware fix outlined here:

http://dl.xda-developers.com/attach.../4/6/0/1/8/uploadfromtaptalk1364659918604.jpg

Instead of reballing the chip, simply applying pressure to it should do the trick. Open up the back of the phone and remove the surrounding screws, then remove the black screw that holds the shielding down (that has the Sim and SD slot on). Unplug the cable that holds this section to the board and look for the chip outlined in the picture. Place a small washer or piece of plastic over the chip and seal everything back up.

It SHOULD work! It worked perfectly for me guys. The issue is definitely not software related if you've tried all of the fixes!
[Galaxy S III Q&A, Help & Troubleshooting] holydire:
i have the same problem.

what weird about the whole situation is that sometimes, when i decide to take the bet, i answer the phone and get sound.

in this situation , the sound will work during calls until the restart of the phone.

how the hell can this be explained logically?

thanks!
[Galaxy S III Q&A, Help & Troubleshooting] holydire:
An update on the issue:

when the phone starts working randomly after a day or two - it will work until it is restarted.

is there any logical explanation for this? thanks!
[Galaxy S III Q&A, Help & Troubleshooting] menacenz:
This works 100% for me too!

Thanks a lot. This worked PERFECT!

This is the fix for the issue where you cannot hear calls via the speaker and basically noone can hear you and if you don't hangup you lose your connection to your provider and it then starts again after 1 minute.

Basically the phone is dead for sound and mic. Yet your phone works fine for every other type of mic / sound function. I think the key symptom is the drop out of connection after X amount of time for this issue.

If you are getting those EXACT issues I recommend you try this fix. It saved me hours mucking around with rom flashes and what not and saved me taking it to a shop and asking them to reseat that chip.

One thing I will note is that the link to the diagram above does not work for me but you can find another picture of it in post 88. I did as DumbPanda did and placed a small bit of plastic on top of the chip so when the sim card casing etc. is put back on it puts exta pressure on the chip holding it in place.

Thanks mate :)

Also of note is I read about this chip being the issue on another forum by someone who repairs the phones for samsung and said this is pretty much 100% of the time the issue and the whole board rarely ever really needs replacing as samsung seem to be doing or saying they are doing.

At worst just the chip itself needs replacing.

Yup. Definitely was a hardware issue. I could have told you that. I had to send it to Samsung to get fixed but it happened again 3 months later. Good to know there's a fix.

This worked perfect for me, I tried everything on this thread, I thought it could be risky, but it wasn't and works like a charm, I used a self-cutted little piece of a credit card to put some pressure on the pointed chip, and now everything's just solved, definitely a hardware issue.

To give credit where it's due, I'd just like to point out that djender (posts 35 and 38) originally uploaded the image showing the chip placement (you can still find the image there), and suggested reballing the chip. Along with dumbpanda's idea in post 132 of using pressure on the chip, hopefully this will sort the problem - thanks to both of you guys for your thoughts :good:

I have the same problem (no sound in calls either way, and dropped signal after a while). I'll be trying the fix tomorrow - will post whether successful or otherwise...

[Galaxy S III Q&A, Help & Troubleshooting] reverez:
Problem solved!! djenda and dumbpanda, you guys are awesome! Thanks for your help.

I spent quite a while trying to fix this problem, read all the posts, flashed roms, turned sounds on and off, downloaded apps, etc. But it turned out to be a hardware problem with a pretty easy fix.

If anyone has that problem (no sound in calls, but all other sound is ok, and dropping signal after a while), then the above is your answer.

Hi, Thanks for teh explanation, finally I have found something with sense! I was trying changing ROM, configuration, etc without success. Now in my phone the BGA appears like reprocessed (maybe it was reballing in a Oficial Center?) see image. I am trying making pressure in the BGA without success, the problem continues... I have an air blower in order to change BGAs but in this case is very small, only 32 pins, anyone has the correct method to reballing the chip? (My problem is that the call is established, you can see the counter of time, but I don not hear and they do not hear me, and the signal goes off after few seconds or a minute, and then comes back again, I think I do not need the REPLACE and only reballing is enough... please, I need to solve this problem!!! thanks in advance

Dr yr image u seem to be mess up the chip. Actually u dun need to reball just need to reflow. I did it with a heat gun.
[Galaxy S III Q&A, Help & Troubleshooting] w1r3d:
The image has been taken with a digital microscope, and the chip seems burned, but it is only a silicone drop that it was on the chip. The image was taken before apply heat, now we can read all the legend of the chip. I have relowed with a heat gun, but I do not get success, and I do now want to burn nothing... How much temperature, flow and time do you use to reflow the chip? how many distance between the chip and the gun? thanks

Yessss!!! I have applied more heat to the chip and now works ;)))))))) Thanks guys you are the best!!!

If someone is still confused...

simply applying pressure to it should do the trick (if chip is not burned)

This is not a definitive solution

Hello,

thanks for the solution. I have applied the pressure on a es305 but, of course, this is not a definitive solution. After 2 days the audio during call problem return. I have tried a reflow on this chip but I did not have success. I did not exaggerate with the temperature because i was afraid of damaging it. Any of you have tried to reflow this chip with success? Can you share the method you use, please? Thanks!!!

I had the same problem and reflowing did the job for me. At first i to were afraid of overheating and had a negative answer on that. After that i heated the hell of that motherbord with the concentration of heat on the chip. After that the sound works flawless. If you are not afraid apply much heat o tbe chip and should work. But do this at your own expence. That did the job for me

As I like doing those things :) , here´s a little info-app.

For those lucky ones, who just need to refresh and update speaker, the app might help.

[Galaxy S III Q&A, Help & Troubleshooting] reverez:
Hi, one other thought on the piece of credit card suggestion - I've tried this for a while, but after some time it stopped working. I've now ALSO put a bit of credit card on TOP of the metal bracket, right above where the chip is. This helps to add more pressure to the chip as, when the main plastic body is screwed down, it is also pushing down directly onto the chip through the two pieces of credit card.

If this stops working I'm going to have a go at reflowing...
[Galaxy S III Q&A, Help & Troubleshooting] alextodd:
Small washer or piece of plastic over the chip? What does that suppose to do? What if the problem is not in the chip but in circuit then?
[Galaxy S III Q&A, Help & Troubleshooting] DumbPanda:
The chip is attached to the board via 'balls' of solder, which can crack or lose contact with the copper pads on the circuit board. Applying pressure helps the chip to maintain contact with the board, but this is only a temporary fix. To fully address the problem at the source, you have to reheat the entire chip so as to melt the solder balls underneath to the circuit board. You can see what I mean by searching on Google Images 'BGA Defect'.

It is rare for the actual chip to fail, as the actual silicon that makes up the circuit inside is protected by the black package around it; it is far more likely that the issue lies in the connection to the board rather than the internal circuitry.

Hope this helps :)

No sound during calls

hi everyone, whoever has this problem of unable to hear dial tone and the caller, can try installing a app called EX Dialer - Dialer & Contacts by Modoohut.... hope this help u all guys thanks and best of luck..... :good:
[Galaxy S III Q&A, Help & Troubleshooting] gziggy:
Thank you rori~ for the excellent summary, and the app. I have an S3 i9300 with this exact issue, I read all 16 pages of this thread and think I understand the issue pretty well now thanks to the efforts of all you talented people including djender who discovered the issue first way way back on the thread as well as important contributions from dumbpanda and others (sorry I forgot everyone's names), but THANK YOU TRULY for everything you do for the community, this was one of the most excellent threads I've read.

Unfortunately for me the app didnt do the trick, neither did applying pressure on the chip (did that a couple of times, still no sound). I LOVE THIS PHONE BECAUSE IT HAS AN FM RADIO, it is SO UNIQUE and useful, I would rather fix it than get a new one. If carriers in the US weren't so evil they'd leave FM radio chips alone and I'd just get a new phone, but alas this is the dark age of the bit we're living in and I cant do anything about that, but I can try to save this valuable phone.

I have two questions to the forum Im hoping you can help:

1) who exactly should I take it to for reballing and how much should I expect to pay for someone to do that? I look at that chip and even with magnifying glasses I cannot make out any individual pins, who can work on stuff this small and have a decent chance of not messing up.

2) Im also evaluating the cost/benefit analysis of buying a new motherboard vs. reballing and the risks there. So I guess the question is where can I get an exact motherboard replacement that includes the FM radio chip on the motherboard for an i9300 and not some other variation of an S3 that wont have the FM radio on it?

Any advice on the above would be truly appreciated. All the best.

Hi,

I have the chip eS305 problem : when I call I can get but I have no sound and no one can hear me and after some seconds call shut down and network lost ...

I solved the problem for 2 weeks by pressing on eS305 chips behind SD card. But the problem reappeared.

How can I remove glue arround the chip and how I can put the new one ?

[Galaxy S III Q&A, Help & Troubleshooting] JoshR81:
Hi. I've read most of this thread, and i've tried numerous software solutions.

I'm going to try the Audio IC chip pressure mod, but would much prefer to either reflow or reball the chip, as i'm planning on selling the phone. I don't want the buyer to have a dud phone in a couple of weeks, cause it doesn't sound like the pressure mod is a reliable long term solution.

For the people who have performed the reflow themselves, have you used a heat gun or a soldering iron?

Where have you applied the heat; directly onto the black top of the chip, or underneath, or onto the board adjacent?

Or have you used a heating plate, and heated up the entire board evenly?

Is there a technician i can send this to that can perform the reflow/reball?

EDIT: PS. i did the pressure mod, and it bloody worked!! Can't believe it. Currently researching reflow of chips.
[Galaxy S III Q&A, Help & Troubleshooting] Guillaume2x:
Be careful with reflowing

I'm hoping that posting this will help someone avoid making my mistake. Here's what I did:

I had the same problem (no sound during call), and pressing on the chip seemed to help, although very temporarily.I decided to try to reflow the chip.

I put the motherboard in the oven twice (ten minutes each time, 380F). It did not damage anything, but it didn't solve the problem.

The next day, I tried to fix it with a heat gun, concentrating the heat on the chip. After a few seconds I heard a "click", probably indicating some heat-related rupture somewhere on the board.

Now the phone is dead and won't start. So if you want to try the reflow route, it would probably be a good idea to preheat the whole motherboard before you use the heat gun, so as to avoid this kind of heat-related breakage.
[Galaxy S III Q&A, Help & Troubleshooting] JoshR81:
Thanks for the advice.

The Lead Free solder that's on the board, has a melting point of ~220C. If you put it in the oven at 380F (193C), then the solder balls wouldn't melt and reflow.

Also, if you put it in the oven wouldn't the solder on the other side of the board melt too, and the chips fall off? That's what i'm worried about.

There are a lot of reflow videos on youtube, but none are comprehensive. Heaps on Xbox and PS3 fixes.

You also need to put up a barrier to protect the other components, so only the chip you want gets the heat.

I've got an infrared thermometer to monitor the heat.
