[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] In call audio problem (not mic cut-out)?

I was wondering if anyone else has experienced this. I tried searching for the problem but it appears that most of the results that come up regarding in call audio issues were the microphone cutting out.
However, the problem i've been experiencing is for long phone calls with my gf, the audio that i hear on the receiving end seems to go in and out. What i mean is, the call will start out normally and everything sounds crystal clear, but after maybe 20 min, my gf begins to sounds really muffled as if she were talking to her phone from across the room instead of having the phone against her face. After a while the audio becomes loud and clear again.
She claims to hear me fine throughout the call, but it becomes almost impossible to make out what she's saying even on max volume (with and without the headphones too). Im not sure if it's an issue with my phone or hers (an iPhone 4s). I've had this issue on 4.0.2, and 4.0.4. I'm now running AOKP's 4.0.3 ROM and the problem still persists. Any help anyone? this is really annoying, esp for a long distance relationship!

[Q] Mic crackle with Wi-Fi enabled?

So a friend of mine has a Sprint Galaxy S3 running the latest official Jellybean 4.1.2 that the phone came installed with. The phone has issues with transmitting voice audio, specifically when WiFi is on. To elaborate:
-When talking on the phone with a headset plugged in, my friend's phone emits an intermittent buzzing noise that is audible to the person on the other end, but not her. The noise lasts for a moment, and then goes away. It sounds exactly the same every time it is heard, but happens at random times.
-Whenever using VoIP apps such as Skype/Google Hangouts with a headphone mic plugged in and WiFi on, an extremely loud static/crackling noise is heard by the person she is talking to. The moment WiFi is disabled, the crackling/static is gone, and the other person hears her clearly. Again, she does not hear any of this noise, the person she is talking to does.
-Unplugging the headset in both occasions and using the phone's mic nearly eliminates the amount of static heard. However, in VoIP apps, again, static is heard by the person she is talking to when she speaks, but is less noticeable than with the headset plugged in.
-In all instances, the static/buzz is gone when she disables WiFi and uses mobile data while talking on the phone or Skype/Hangouts.
I've tested this issue with her and the noise is similar to the rapid tapping of a Geiger counter. Is anyone familiar with this issue? Is there a fix? She returned the first phone for a second, and both have the problem. If there's no solution, she is highly considering returning the GS3 and seeking a different model. Thanks!

Did you ever find a solution to this issue? I have the exact same problem. Did you try a different mic than the standard samsung one? You are the only person I've been able to find online even mentioning this issue =/

I know someone with the same issue on the SIII Neo in the UK. I do not know of any solution at all. Brand new phone. Odd for Samsung

Bluetooth drops to handset volume on incoming calls while on a call.

I'm currently using an LG G3 Vs985 on Sky Dragon 5.0
I'm also using T-mobile on the LG G3
I use my phone for work a lot and the most annoying thing is happening. While I am using my bluetooth headset and talking on a call, if somebody tries to call me and my screen is telling to either accept or deny the incoming call, my bluetooth speaker drops to handset volume. I have to deny the incoming call, then quickly tap to turn off bluetooth and bluetooth again to get the call back to my bluetooth.
While already on a a call if somebody is talking to me while an incoming call comes in, I miss an entire sentance or two before i can do all of the above to get the audio back to bluetooth.
Is this a wrong setting I have on the phone or simply a bug with either Lollipop or Skydraggon?
"Edit" I got so annoyed I went to my wired headphones and I noticed the issue is not happening on my headphones. I didn't expect to happen but i wanted to note that the audio does not drop to handset speaker while using wired headset.
I appreciate the help.

I wanted to update the post that either it was a phone reboot or possibly of me flashing the Skydragon 4.2 kernal to the phone that fixed the issue. So far as of right now the audio is not dropping when talking or listening on an active call with another incoming call requesting to be accepted or denied.
Edit: The issue has returned. This is goofy !! lol

N5X voice call problems - my voice severely muted / garbled for other party

Nexus 5X, Stock 8.1.0 with security patch level 5 April 2018.
If I make or receive a call, the other party cannot hear me, my voice is severely muted and garbled. I've tested this by leaving messages on my home phone and all suffer from exactly this.
Now the microphone itself seems to be fine - WhatsApp voice messages are perfectly clear, I installed a voice recorder app to check and the recordings are good. Google voice searches also work fine.
I've done a factory reset. I've uninstalled updates to the Google Phone app. I've swapped SIMs. I've tried alternative dialers. I've turned on/off 2G /3G /4G. But my voice calls are always rubbish.
Anyone have any ideas as to what might be going on or suggestions as to what else to try?
Thanks!

Hi
I'm just visiting here with the same problem. I've been getting complaints about call quality from my end for a little while and it's driving me mad trying to be heard, often it starts off okay, then degrades rapidly after a few minutes, other times its from the start of the call. I've done the same as you, the mic tests fine in other apps, and sometimes it works okay. I did a complete factory reset which did seem to improve things but the problems returned, and no, I hadn't added any apps in between it working and going back to being terrible.
I've also tested calling my home answer phone and leaving a message to see what people are complaining about, and it is just constant drop outs. This happens over Wi-Fi calling, and over the network (EE network/UK), so it's not a reception problem. I've also used a plug in headphones with microphone and it's the same problem.
I really didn't want to buy another device at this time, but to me it's looking like a hardware problem.

Phil

Before I did the factory reset I had tried turning off noise reduction in the build.prop as recommended to try but it made no difference.
It sounds to listen too as though it's a faulty connection, and I'm thinking now this might be related to the reboot loops caused by connection problems, and this has the same cause, broken connections on the main chip. It's odd the sound is okay when recording sound or video, however that might simply be because the sound is being routed and processed elsewhere, and it's only when it's compressed for a call and routed via the Qualcomm modem that it's affected by a faulty connection. This would explain why sometimes for me it is okay, or starts of on a call okay then as the phone warms up the connection starts breaking.

Hi
I've now upgraded to a Pixel XL 2 as I needed to be able to be heard on calls and the 5X was out of warranty and LG didn't want to know. I really didn't want to upgrade quite so soon. The XL with the same SIM card on the same mobile network is all good and everyone can hear me, plus I have the benefit of VoLTE.
I believe the microphone problem is hardware related, most likely the same cause as the boot loop issues where the CPU or board has some broken solder connections. It sounds like a broken connection, and explains why it has progressively become worse. It's a pain as usually when I upgrade my phone gets handed over to another family member, but I can't do that with the broken 5X.
