[Q] In call microphone volume low

The microphone volume is very low on my dhd, people can barely hear me when I call them. The sound is also low when I use a voice recording app. When I plug in an external mic the sound is fine though.
I've been looking for a solution for this for a while, does anyone have any suggestions?
I'm running MIUI 1.5.20, but I had issues when I was using the stock ROM.

Yes i have this problem, often people complain they can't hear me any good.
However if i turn the phone with backside towards me they can hear fine so i guess it's a design fault that they place the microphone at the back, why?

Did anything ever come of this? It's just that I am experiencing the exact same issue

[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?

How do you adjust the voice codec?

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

Nexus 5X Microphone

So here is the problem. I have tried talking to Google Support and also LG Support. Not under warranty anymore. I have heard several different people mention problems with their mics in calls, be it incoming or outgoing. I have done several things to try to fix this problem; flashing stock firmware and upgrading thru OTA's, clearing cache, rebooting every day, flashing custom roms, modifying the build.prop, opening the device and checking for physical damage. To my knowledge this phone has 3 microphones that are used for actual speaking and background noise reduction. When I opened the device everything looked ok on what I assumed were the mics (the tiny square bits soldered to the logic board at the top and the bottom). I assume these were just going bad and finally gave out on me. Has anyone had any experience getting these fixed or repaired? Is there any software based approach I can look into? I am really tired of using my speakerphone in every call. I assume I am not the only person with this problem.
If anyone can shed some light on this or help in anyway I would appreciate it
Thanks!

I would start by describing the mic issue you are experiencing during voice calls.
Haven't had any myself.

No one can hear me using the microphone, as soon as I switch to speakerphone the other party is able to hear me.

I've read mics can stop functioning if you try and clean the phone with compressed air. As far as fixing or replacing a mic I am unable to provide assistance.

Well rats. Hopefully someone can shed some light on getting this fixed. I do have some soldering experience but I don't even know how this translates via the logic board. Anyone that has more information the help would be awesome. Thank you for your time though previous posters.

I have this problem as well, but also all media volume can't be heard through the speakers. I've personally cleaned and replaced the unit and nothing works, I just have to choose speaker and start talking, else use a headset or a bluetooth mic

Same problem, no solution yet.
Think that is a software/driver/app combination bug.
When Iam in call hardly can anyone​ hear me, if I cover top mic - then im heard again (proof that bottom mic is working).
Top mic is used to cancel background noise, phone interpret your voice as background noise and volume it down. That way nobody can hear you.
When I cover top mic - no background noise detected and my voice is heard again.
Question is why top mic detect legit voice as background noise?

Same problem here. Can't use microphone normally on any sort of voice call. I have to change to speaker for people to be able to hear me. I'm not sure if I still have warranty so if it's a software problem I might be able to fix it by myself.

Redmi note 5 pro microphone problems

Hi there,
So i bought redmi note 5 global version which seems to be identical to note 5 pro. Problem is during skype calls and even phone calls the recipient can not hear me clearly most of the time. Sound becomes muffled and incomprehensible, person can hear me but can't make out what i am saying. It does not happen constantly, issue comes and goes. I am on 9.6.4 MIUI version.
Does anyone experience the same issue? Could it be firmware issue or charging pcb microphone issue. I don't feel like dealing with warranty since i have sensitive data on my phone, i spent ages setting everything up and it would probably take long time to get it back. I was thinking to replace microphone pcb myself since they can be purchased for 10 buckaroos and replacement it is easy and straightforward.
Does anyone have some insight into the problem or has dealt with it themselves.
Cheers

miui 10 is out
please upgrade and try

So i upgraded to MIUI 10 and issue persists, doing some reading it seems during voice call apps like skype top noise canceling mic goes bananas and messes up sound for recipient.
I feel changing bottom mic pcb won't do anything. There were posts about disabling noise canceling but for some reason those posts are taken down.
Does anyone know a fix other than throwing my phone against the wall. I need to use skype a lot, i've gotten used to my lil redmi, would be shame to buy smth else.

Have you tried this:
https://forum.xda-developers.com/re...gisk-fix-bad-camcorder-audio-quality-t3828711
It fixes the static background noise in recorded videos,but it might work in skype too

I have the same issues like Dzessi.
Mic is an garbage, unusable. Allmost all the time is not working properly, expecially in games or apps (voice chat) is low, high, diatorcions, radio white sharping noise, echo. I ve tryd everything on YouTube an papa Google, nothing solve it. I receive it in September as my bd gift, and I can't enjoy it, so frustrating I never write so many mesages on apps since I ve got an Java phone, nobody wants to voice chat anymore, (my brother recorded me and send me the voice message on whatsapp) well, I didn't voice chat whit me allsow in that horrible noise. If someone can help me solve this I ll be so happ. thanks in advance

I also have the same problem. Some say that some of you talk nice we do not hear you. Does anyone know the way to overcome it?
