[Q] Crackling call quality - Galaxy S III Q&A, Help & Troubleshooting

Hi guys,
Recently after trying a custom rom, my call quality have been appalling, it sounds very distorted when receiving or making a call, the other side can hear me fine but i cant make sense of what they are saying, everything else such as videos and music play fine, just calls. I have flashed the correct modem, re-flashed the rom as well as trying others, just did a factory reset and am in the middle of downloading stock rom to try that, but was wondering if anyone else has come across this before?

[Q] [Help] Phone dosen't ring trough back speaker.

Hi, I seem to be having a problem with my phone and I can't seem to resolve it. Back speaker works perfectly while playing music, playing game and watching youtube videos. Also works fine when I set a ringtone and it plays a sample. But when I receive a call instead of the back speaker ringing it is the front one that ring, yes the earpiece. I was wondering if anyone has an idea how to fix this?
I'm currently using a default android ringtone.
Using the stock JK6 Rom with the JL1 Baseband and the Stock JK6 Kernel injected with Voodoo 5.X
I can't say for sure which of these flashing caused the problem since I flashed them all one after another unable to test and detect such problem.
Thanks.
Resolved! It's a behavior of the WiFi Calling App, guess I'll have to install another one.

[Q] No sound during video call, just loud static noise

I have looked through the forums and googled this far and wide, but couldn't find anything. When I make a video call there is no sound except a very loud static noise. Has anyone had a similar problem?
I'm on Pure ICS Rom by Spike_M, have tried different kernels and modems, but couldn't fix it. The interesting thing is that my brother has the same Rom and setup on his SGS2 and he doesn't have this problem. Also video calling through Skype works fine!
Appreciate any help!

[Q] Odd speaker problem

I have read other posts on the forum but believe my problem is a bit different and quite weird (to me).
The symptoms are:
- sound through headphones is OK
- sound through the speaker when someone calls me on the phone is OK
- any other sound through the speaker is non-existent (ie ringtones, music, games)
I have tried rebooting, removing the battery, plugging/unplugging the headphones. I have tried the *#0*# code and pressed "speaker" but there's no sample sound heard (except through the headphones).
Does anyone else find it extremely odd that the speaker seems to work fine when someone is talking to me on the phone but nothing else? I'm guessing this means the problem is some kind of software or firmware issue. Correct?
Prior to the problem, I started with Android 2.3.3, rooted the phone, and flashed a stock ROM (KK2). I have upgraded to 2.3.6. Unfortunately I can't be sure the problem occured since 2.3.6 because I don't play music that much, and I play games without sound.
Should I (a) re-flash stock ROM, (b) factory reset, (c) call Samsung?
Grateful for any recommendations. (I'm not confident/competent with replacing the speaker myself)
regards.
Check sound settings first .
Factory reset.
Flash a stock rom .
Rooted so warranty void .
You will need to clear root with a stock rom flash and reset custom rom counter to zero with usb jig .

Receiving a call has a separate speaker, so your problem is with the back speaker which plays tones and other music, do a complete factory reset and check for sound if its still not playing, then it could be a hardware issue.

Thanks for the advice. I didn't realise there was a separate speaker.
I've performed a factory reset but no success.
I'll call Samsung today and arrange for the speaker to be replaced.
Thanks again
I've Had Success..
Hey guys..
I know this threads old, but I had success fixing an AU TELSTRA i9100T with the same Audio issues presented here. Runing GB 2.3.3 Totally Stock.. No root, nothing.
Every-time I increased the Speaker level to more that Half way, I'd hear a deep "CLICK" sound then no Audio any more through the Speaker..
When headphones are in, No problems at all..
Strange thing is, that once I turned it down below half way, and Blew air or puffed or even Talked Loudly into either of the 2 x Mics on the Top or Bottom of the phone, the sound would return OK.... but, again if I turned it up past Halfway ( sometime maybe one step over half way ) it would CLICK again and no Audio through the Speaker.
So, First I was thinking HW, then SW, tried Factory Reset.. no Help at all.. same issue..
Then, I flashed ROM to the latest Stock JB 4.1.2 XWLS8 Spanish ROM floating about the forums and This fixed it.. Perfect sound. No Hiccups.. :good:
Just wanted to share this..

[Q] SGII Speakerphone silent in call

Hi, I'm having a strange problem not hearing anything in loud calls.
The scenario is following: I dial the number, the other party picks up (or the other way round), I switch to loud speaker and...can hear nothing (neither from the earspeaker, nor from the loudspeaker). Microphone works normally as it should in the loud call - the other party hears fine. Normal calls (not loud ones) also work fine. Speaker itself is also working - ringtones, music are played.
I'm on the newest AOSP Neatrom 8.0st (KK 4.4.4) and Apolo Kernel 7.1. No other issues so far.
I'm quite new to custom ROM/kernel flashing, also I only recently got my hands on Samsung GII. Sorry if this is a stupid question. No reasonable search effort gave me good results. I'm asking this before I ruin my successful combination of ROM/kernel flashing another ones.
Thanks. Martin
Ok, problem solved by clean re-flash of ROM and kernel.
Still I would like to understand where the problem could have been. Just if it reappears...

Microphone and earpiece not working on outgoing calls lollipop 5.1

Hi I have a Cubot Note S that runs lollipop 5.1 and I have recently noticed that when I make an outgoing call I do not have any audio and the other person cannot hear my voice. I cant even hear a dial-tone. The weird thing is when I receive a call everything works fine so it cant be hardware related.
I was wondering if anyone else has come across this issue and manged to get it sorted. I have tried a variety of different dialers from the play store as well as messing around with the sound settings but nothing seems to work.
