[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.

Poor call quality / distortion / noise , anyone else?

LG-D855 here on UK Orange (EE) network. I get quite bad noise on voice calls. I think I am clear to the other party but I can hear a bad static sound whenever they talk, it is quite irritating.
Call quality is clear on bluetooth, and and when on loud speaker, it only happens when using the normal internal speaker.
Has anyone else experienced this? Since it is not present across all speaker modes I think it is not a network issue and more likely hardware - I am wondering if I have a faulty handset?

Thanks that is useful. I wondered if it was an EE issue as I had problems with their hd voice codec on a different android handset. But I have just done a lot of testing and it definitely is only when on the normal internal speaker, which really makes me think it is a hardware fault.
Will phone CPW and get it swapped.

Uh, how to unroot?

I'm on 3 and the call quality is excellent, I can now use the phone in places where I couldn't with my s3

Don't worry about it there not going to know about if it's rooted just uninstall supersu or superuser which ever you have

Mine has had good call quality on the hd voice codec, but it drops to a lower codec really quickly during a call, not sure why. and that seams to have a little static. Cant remember if this was what calls were normally like on my old phone though.

Hmmmm. I tested again today and the noise is all gone: calls are crystal clear. I really don't understand what is going on, or whether it is software or hardware related.
I suppose it is best to swap it out before I have had it for too long, just in case?

Useful, thanks.

I have the same issue but only on GSM calls. Weirdly whe. I use Skype the calls are crystal clear which therefore eliminates hardware issue unless it's the GSM attend interfering with the earpiece.
Any ideas what I should do?

I don't think you can. The operator will alter it according to signal conditions AFAIK.
Just to complete this thread: I have swapped the phone at CPW under their 28 day guarantee and so far the new handset doesn't exhibit this problem. Will update in a few days time.

You dont. Its automatically selected by the network/phone. Mine seams to start off with clear sound then quickly drops to a lower quality and never recovers for that call.

I had the same issue in Slovenia, I changed phone for new one, but the problem is still here. I find out that I hear that noise only when phone is on 2G/GSM.When I switch to 3G/WCDMA only the sound is perfect, also when I use Skype. Did you try to switch on 3G/WCDMA only?

Yeh I tried switching but same issue. I exchange thr phone, no problem with the new one

Hi all, I have a similar problem but the other way around, people that I call hear a lot of static, but ONLY if I am powering the phone. If I connect the phone to a USB port of my PC there is static too, but less. BTW I call using a wired headset.
Other problem, the LG stock headset muffles my voice and people can't hear me well, I had to use a Samsung headset.
Last problem, when I make calls without headset I hear in the phone the sound that you get when placing a phone next to a speaker...
Does anybody have similar problems?
Needless to say I am very disappointed.
BTW, no audio hissing when playing music via Spotify

I have the exact same problem. Have you found a way to solve this? The problem only occurs when I use a wired headset and plug in my charger. No charger plugged in, no noise as per the person on the other end of the call.

kentii, I bought a wireless charger to charge my phone, in which case the problem doesn't appear. I also bought a bluetooth dongle for my desktop to replace the USB connection. I spend a lot of time on the phone and like using a wired headset. I use MyPhoneExplorer to dial from my PC

Anyone got the Carphonewarehouse UK ROM?

I bought a LG G3 which was on the Three network from eBay. I'm getting voice call issues so I'm hoping I can get a generic rom which might help?

Are you getting high quality voice calls for a few seconds and then its dropping to lower quality? or it it just straight crackling and static right from the start of the call?

Hmmm, would be interested to hear whether the software fixes it, but I doubt it. I just swapped my handset because it had the same symptoms. I reckon it was a badly mounted speaker, but then if yours was the same problem then you'd expect it to happen on skype as well.

Software didn't do a thing. And yes, I can't understand why it doesn't impact it during skype calls.
I have had a few calls an it sometimes goes away, so maybe this is to do with the HD voice codec that networks are rolling out. Vodafone might have it's own codec which is not on the device.
BTW, the link on the site for Vodafone UK was the Italian 3 one again!

Ah ok, and that's on on the earpeice? Mines a network codec problem then i think because i don't get that kind of buzzing sound. That sounds almost as if the speaker cant handle the volume?

Yes that's max volume through the earpiece but when you lower the volume and your ear is next to the phone you can still hear it. Almost like an buzz echo. It doesn't happen on skype calls.
Which network are you on?
I'm starting to think it might be a Vodafone network issue.

The way vodafone seam to handle the hd voice codec is it will use it if your on 3g (4g will switch to 3g as they dont have voice over 4g yet), but if the signal goes down during a call or fluctuates (no idea on the thresholds for this) it will drop to a lower quality codec/network type to maintain the call. But it only goes down not up, so regaining a good signal during a call will wont switch you back to the hd voice codec. i might phone them tomorrow about it and see if that is indeed what is happening to me.
But that doesnt sound like the issue your having if the video you posted is what all your calls sound like.

One thing to consider about not having the problem with skype. I do know that other phones (Nexus 4 for example) had problems with audio if your plunged in a headset (earbuds+mic) which wouldn't work properly with gsm calls but would work perfectly fine with voip. Its possible viop isn't affecting whatever problem the speaker has but the speaker may still have a fault.

Is that using the earpiece or speaker? It seems pretty loud for the earpiece!
But yes, mine sounded quite a lot like that.

ok it's gotta go back

Notification sound "fading in" effect

Hello xda,
Any time I receive a text or mail the notification sound starts low but quickly ramps up in volume. Is anyone experiencing this as well? Is there a way to set this so it's loud from the start? Hope that makes sense.
I appreciate your help and time

I noticed when the phone rings sounds only by the lower speaker, and sound very low and muffled.

Many others (including myself) have noticed and posted about this issue here (though not enough in my opinion). It's not restricted to notifications and ringtones either, it happens with *all* sounds on the phone.
Unfortunately, there is no way to fix it. Different sound drivers, updated firmware, build.prop settings... Nothing seems to get rid of this "speaker protection" crap. I am still hopeful to someday see a mod or firmware update that addresses it though, because after trying all those different things, I've run out of ideas.
Sent from my HTC 10 using XDA-Developers mobile app

I've also noticed that, it sounds fine when I preview notifications and ringtones, but when the phone actually rings it is a lot more quiet and muted. It does appear that the top speaker is not being used for ringtones. I'll try to call htc, let's see what they say.

Called HTC, spoke with a girl who sounded like she was following some sort of flowchart. Needless to say she couldn't help and concluded that it was a defective hardware. I tried to explain that others are having the same issue and it appears to be a bug, but I don't think she understood. They are sending me a new phone. I'm sure the new phone will have the same issue. Maybe if more people call HTC with this issue, they will figure it out.

Hi there
the same problem here, without any mod, crack o root solution. But the difference were the answer from HTC technical support: " this is a technical and engineering design, it´s not a bug", this mean: " f**** you costumer, and again, a new dissapoint from HTC. I has tried in several forums, here in XDA and another ones: nothing for to do, i loose my faith in the HTC 10. It´s very frustating because a little detail ( the ringtone volume and quality) destroy a overall experience

OH, so they know about it? This is a technical and engineering design fu**-up. My notifications are half the volume of the M8. If that is their answer, then I will probably return my phone.

Any solutions yet?

On mine it rings from the bottom speaker for about 3 rings, quiet, then ramps up and uses the top speaker too. With V4a on now once the top speaker kicks in it's very loud. It gives me a chance to answer it before it blasts me out.

I just bought a new htc 10 and quickly noticed this annoying sound fading in issue, searched online and this seems to be the only place talked about it with no solution, does everybody else really okay with this??
I guess at least it sounded fine when using headphone, but with this speaker fading crap everything sound like its echoing right now. This NEEDS to get solved.

Any solution ?

I came here to search for any ways to turn this "feature" off (and that's what it is, despite how nobody asked for it or wanted it). Looks like nobody has found any solutions. But here's my theory anyway:
The "fading in" volume effect must be a function of the Boom Sound software. It's a noise gate. And it sucks. For instance, try listening to any music that has any hard hits around any silence (a good example is "Brain Stew" by Green Day). It's really annoying.
I wish somebody could figure out how to disable the Boom Sound software altogether.

According to Google, https://www.google.com/search?newwi...0i22i30k1j33i22i29i30k1j33i21k1.0.leWX0kmgR6I it's a known Feature of Android 5, and many people complain about it, but there is no way to disable it.
Some people can workaround the issue, on some rom, with some apps or players; there is no universal solution.
In the best case, some chat app will not bell if they are already full screen; and this is an issue for me because if I have my phone plugged, and display timeout is 1h, then, it won't bell for incoming messages, and if I am >1m from it, I won't know people are talking to me. That's why I try to always make all apps always bell. But, if I am listening to music, the permanent bell that comes with intense chat may turn the music off all the time.
I not sure if I shall downgrade my phone to Android 4, 2.2, or 1.8 ...
.. arg, I am stupid, those versions have never been ported for my most recent phone.

silent phone calls

I keep having phone calls where I can't hear the other person and vice versa. Seems to be related to my Bluetooth connection to a Gear S3 as disabling Bluetooth usually fixes it (but then sometimes it randomly sides itself with Bluetooth on and I haven't done detailed testing).
I'm on Fi, but have been for awhile and never had this problem with my previous phone... I am using the software sim.
Anyone else experiencing similar, or know anything about it?

It's off. I should add, there's not even the sound of the ring, just dead silence and the timer starts, then eventually a disconnect. That's making me think the audio is being sent somewhere besides the speaker (even though the icon says speaker).
