[Q] vzw gnex - crackle and popping sound during incoming call.

First off, forgive me if this was already answered, I tried searching for about 15 minutes before I decided to post this.
As the title states, I'm having an issue with my gnex where I get this high pitched and crackling sound when receiving SOME incoming calls. I can't hear the person, and whenever they speak, the noises get louder so I can't hear them at all.
I think it's software, rather than hardware, since it doesn't happen on every single incoming call. From what I can tell, actually, it's totally random. But if I call the person back it is fine. They could even call me right back and it's fine.
My friend who also got a gnex from a different vzw store has the same issue. His also appears to be random.
Do you guys think it's just network, random phone problems, software issues, or all three?
Info: Verizon Wireless CDMA Galaxy Nexus running fully stock 4.0.2

For the record, I too am experiencing this issue. I also have the issue via 3.5mm jack and during other audio playback. At first I thought it was just my low-quality aux cable I was using in my car, but then I experienced it on a normal call. I was thinking software for this reason too as it happens via the jack as well as speaker... (Also happened watching Netflix, so that covers all audio output but bluetooth.)

Are people on custom roms experiencing this? I wasn't going to root this phone as I didn't see too much of a need, but I will if it will get rid of this issue.

if by crackling you mean it almost sounds like a fax sound, squealing, similar to this description, http://forum.xda-developers.com/showthread.php?t=1453769 , then yes I had this when I ran stock but now that im running francos, AOKP, and the 4.0.3 radios(which arent included in most 4.0.3 roms), i have not had the problem.
My GF had a problem where her mic was bad, about 50% of the time i got a call from her she would sound muffled, almost as if underewater. She exchanged it at VZW and haven't had any problems since.

[Q] microphone almost inaudible, works fine on speaker

I'm running a stock galaxy nexus, and since a few days (suddenly), people can't understand me anymore when I'm not on speakerphone, I sound really far-off and muffled.
Since it's working fine when on speakerphone I'm suspecting either a fault in the noise cancellation or with the microphone which is used in regular calls.
In the stock android I run I don't find an option to disable the noise cancellation.
Can anyone recommend me a rom which has this option? I'll be giving the phone to my wife next month (provided I can fix this problem), so I don't really care one way or the other if the experience/ui of the new rom matches what I get from stock android. All that matters is that the phone works well.
If disabling the noise cancellation doesn't pan out, would there be any way for me to force the phone to use the secondary microphone for all calls? (Since it still works fine on speakerphone...)

Microphone not working properly after lollipop ?

My in call mic, as well a google now hot word, is not working after installing the latest firmware for lollipop.
It is recording at an extremely low volume. People say I sound muffled and far away.
To get "OK google" to respond I have to put the mic right next to my mouth.
Every thing is fine when using speakerphone .
Are there two mics in the phone? Why would it not work in normal call mode and be fine on speaker?
Also after a google search. I found people in the nexus 5 community with the same problem.
Tried flashing older lollipop firmware to no avail. I haven't tried going back to sense yet, as I want to keep lollipop.
Any help or ideas are appreciated.

Strange. Try reflashing it. Make sure to wipe.

Anyone? If there is two mics is there a way to switch when they work. I'm mean to say have the speaker phone mic work as a regular in call mic

This is making me crazy. I can't send the phone to HTC, they want $400 because I used HTC DEV to unlock my phone.
Sometimes it works fine, like 5% of the time. Speaker phone mic works perfectly. I have to put the phone right near my mouth to get "ok Google" commands to work.
Does anyone know how I can get the other mic to act as the primary one?
Searching the interwebs. There are rumors of the noise cancellation causing the issue. Idk?
Can't buy a new device. I'm stuck with this one. It is beyond frustrating.
I've flashed, RUU'D everything under the sun to try and fix this. Nothing.
Anyone?

Microphone not working during calls

Hello,
Spent all night/morning trying to find a fix to this issue but to no luck!
Basically during calls my voice isn't heard at all (But I can sometimes hear my own echo) (Tried numerous ROMS based on stock and CM) but when I put my device on speakerphone I can be heard. Blowing into the mic during a normal call emits a normal blowing noise down their side of the phone but speaking into the mic directly does nothing.
I've tried cleaning the mic out but again nothing, no debris etc.
I've already sent my phone back due to a raised screen and LG didn't fix it- they sent back photos of a completely different phone (wasn't even a G3) and I've heard nothing since my complaint a few weeks back so I don't want to send it off once again.
Any ideas?
Thank you

Microphone and speaker problems

Hi everybody,
I recently bought an used phone in Spain. The phone arrived with android 9 (I don't remember exactly which version) and I checked all the functions with the service menu. The only thing that worked badly was the secondary microphone, which had a recording volume extremely low. I thought it could be fine anyway. So I updated the phone OTA, then I did a companion restore (to 52.1.A.0.618). At that point I put the sim, and made the first whatsapp call. Everything was fine at the beginning but at the end of the call, the speaker started croaking (badly). From the service test I identified the bottom speaker (the one called right) as the malfunctioned one. So, thinking it was the fault of the update I downgraded to Android 9, following the guide on that forum, but it didn't work. Then I updated again with flashtool to Android 10, first with the Italian firmware (to 52.1.A.0.672), then with the Iberian firmware (to 52.1.A.0.618). But in both cases even the microphone no longer works correctly. If I record video, the microphone works fine, while if I make calls, the microphone works only if I put it on loud speaker. In the normal mode the interlocutor hears me but at a very low volume. Same problem from the service test. The microphone works, but only if I speak attached to the microphone hole. I tried to clean with a toothbrush, but problem still there. The phone has no cover.
Any one faced similar problems?
Fixed by replacing them. Now facing touch screen issue (updated to 52.1.A.0.672)

Hi,
I bought an XZ2 Compact recently and downloaded every updates. The last one is the 52.1.A.3.49 and I have the problem with the microphone : working for recordings or calls on loud speaker but not working for calls without the loud speaker.
What can I do ?

I have very similar problems with a used phone that I bought (secondary microphone very low volume). Am I reading you correctly, that you installed a new microphone and this fixed the issue?
