[Q] Calling problem- caller can't hear me and vice versa - Android Q&A, Help & Troubleshooting

Hi,
I own a SGS3 and I couldn't find the answer to my problem anywhere. So basically I had Cyanogenmod on my S3 and one day somebody called me and I couldn't hear them (they couldn't hear me either). I tried putting them on speaker and still nothing. I thought that maybe my phone was damaged, so I tested the mic and speaker on Skype. Surprisingly, it worked perfectly. I concluded that it must be a software problem, so I tried going back to factory settings - nothing happened. I just got my phone back to the stock OS but the problem is still there. Any help, please?
Thank you in advance!

[Q] Microphone not working

Hi, I'm a bit of a newbie to XDA, but I came across a problem which I browsed the forums and the internet for a few hours to solve to no avail. A few days ago I made a call to one of my friends who apparently couldn't hear anything from my side. I checked this over and restarted my phone a few times to see if that would fix it. Unfortunately the problem persisted, and when I tried to record any audio, all I would hear from the playback is noise. I assumed that it was a faulty flash of Trigger v2.8, but ODIN'ing back to stock didn't seem to fix the problem. I use the phone in Canada, and won't be visiting the US anytime soon, so I can't go to a T-Mobile booth to get it checked out. Is there anything I can do? Any help is greatly appreciated.
check settings and make sure you do not have anything off, that could happen, But if you can't resolve find a compatible kernel for your ROM and try flashing that. That usually will fix most problems.
Good luck
Thanks for the help, but I was unable to fix the problem using these methods. I'm starting to believe it is indeed a hardware problem, but I would want to receive some more input and where I should take it to be fixed if that's the case.

Atrix 4G external speaker fail??

Just got my unlocked Atrix less than a week ago and already the external speaker failed on me, everything was working fine and suddenly while playing a video using (mx player) the rear external speaker stopped working, while earpiece speaker and 3.5" audio jack are working fine, here's what i did to check:
- Checked under sound settings/audio effects and found phone speaker connected but still nothing
- Booted into safe mode with no success.
- Did a hard reset a couple of times but still nothing.
Phone is on stock At&t 2.3.4 (4.5.91 Firmware) without any mods, and hasn't been dropped or anything, very strange and frustrating as ive been wanting this phone so bad and this happens in less than 5 days
don't know if its s/w or h/w related if either what is your opinions on fixing my problem.
one more thing cant return it for maintenance as im not in the U.S. (had my brother sent it to me) and the process of sending it back to him is not so easy.
so please help me out..
Thank you all.....
Any help please, is there a s/w fix i can try or speaker replacement is my only solution??
if the second, please recommend me an online repair/parts supplier i can check as i cant find any..
Thanks..

Big Help Needed

Right guys, I have been on the Original Development section asking similar questions and had good suggestions, but here is the problem in a lot more detail as I don't want to spam the section with the same problem and get literally no reply as people are busier with other things on there. Basically the phone has it's two speakers, the earpiece at the front and the speaker at the back both of which are working and functional. However the problem lies in the phone calls. I bought the phone on stock firmware, latest UK generic update it was and everything was fine. I decided to root the phone and flash PA 2.13.1. As soon as I did this I came across a few issues, one being NFC not working and the current and seemingly unfixable issue that I have with the phone calls where, as I receive a call and answer it the microphone doesn't work, I can't hear anyone and they can't hear me. Both on loud speaker and through the earpiece. It's as if they disable when a call comes through. But when I hang up or they hang up I can hear the end call tone, the beep coming through the earpiece. So I know that it works. The same goes for loud speaker, however I already knew that it still worked as I can play music through it cleanly. It's in perfect working order.
I've tried several solutions, including flashing new modems, RIL etc. Flashing 3 part software. I have yet to try flashing the 3 part software with a .PIT file, like mx.pit as I simply can't find that file (if someone would be as kind to link me it) anywhere. I'm currently back on stock XXALE8 UK firmware. The problem is still there. I STILL can't make a phone call without this annoying thing happening, and as I said, the problem wasn't there before I flashed PA. It's so f****** annoying as I followed the instructions perfectly, I mean, I've been using android since 2009 and rooting and flashing is nothing new to me. I've never had an issue as severe as this one.
Anyways, thanks in advance for any suggestions you guys can throw at me, I know you'll all agree when I say the GS3 kicks ass and you'll know my pain when I tell you it's being a broken piece of crap haha!
EDIT: Right, I have made another definite discovery with this problem! It's to do with my signal. When I answer a call or make a call, it appears to connect to the caller for roughly about 0.01 seconds as it says it's connected, but then it hangs silent for a while, about 13-15 seconds before disconnecting saying there is no service in the area. Give it another five seconds and the signal reconnects. It is the exact same effect you would have if you were on the phone on the train and went through a tunnel, it would say you were connected when you aren't. Does this make sense, anyone know what the cause of this could be?

[Q] SGS2 In-call problem

So I normally use a HTC device, but this time I need help with my brother's Samsung Galaxy S2 device. The problem is that from time to time, while in-call, i can't hear anything in both speakers, no matter what I do. The problem seems to come and go without me doing anything. I had it "fixed" in a service, but they just replaced the earpiece-jack module(which seemed to have worked for a day or two, but the problem came back). I have done numerous software resets, using the special recovery that samsung had provided (volume up+home+power), and had my software reinstalled at a service, but nothing seems to have worked. Does anyone have any thoughts on this? If you do please help me..:crying:

Broken Dialer function, freezes phone

Hello,
My problem is very weird and i couldnt find any solution for it yet. Some time ago when someone was calling me i couldn't hear the voice and the caller couldnt hear mine, when i turned speaker on it was all fine. I tried to work it out by installing and uninstalling certain things in the phone and'ive come to the stage where if i try to call someone or someone calls me my phone freeze (nothing can be done) and then restart itself.
My current ROM is latest nigthly CM 12.1.
What could possibly cause this? I wiped everything possible like 3 times already, made factory resets, installed rom again and again, nothing helped..
EDIT: Ive tried installing different ROMS, CM11, CM12.1, Stock Rom, still same issue.
Loading the backup (5gb) of the phone before flashing it and doing all the stuff didn't help...
I had a similar issue on my old S4. Turned out to be one too many "drops" by my baby, cracked the circuit board behind the glass. This caused issues with calls not going through, cant't hear people, it disconnects by itself, sporadic reboots, some force closes, and eventually me trading it in for the S5..lol That was my 2nd replaced board in that S4 in as many months. Needless to say, my daughter does not play with daddy's new phone any longer..lol That was my experience, hope it helps. Good Luck!
Thanks for the answer, but unfortunatly i treat my phone pretty good and it would be a big coincidence if something mechanicly broke inside it, as i said it happened the same day as i uninstalled Hangouts and something else with Root App Deleter...
