[Q] Does Custom ROMs and Custom Kernels have Mic problem - Nexus 5 Q&A, Help & Troubleshooting

Hello Everyone,
I have recently purchased a bright red Nexus 5 32GB, and found that there is a problem with mic.
I have to speak loudly or repeat my words so that the other person on call will be able to hear me.
I have gone through this thread and found that am not the only person with this problem and users have also raised the same in this google group.
Users are stating that they have RMA'd the phone but the problem still exists.
I too have done testing with sound recorder apps and they all seem to record my voice properly.
I want to find out if this problem is only in the stock ROM or does it also effect custom ROMs and custom kernels.
so, anyone using custom ROM or kernel can please check and update us if the mic is working properly in your phone, can the other person hear you clearly. can you check any voice recording app and google keep and confirm if the voice recordings are of same volume and clarity.
Thank You.

It exists for everyone and there is no known fix as yet

Ah, so it's not my network then... lots of people saying I'm either very quiet or garbled when I call them. I wonder if the noise cancelling needs tweaking? Could be that it's partially cancelling our voices.

It is indeed believed to be a problem with the noise cancellation algorithm.
some rooted users change a value in their build.prop to "turn it off" but I cannot say for sure it works for everyone.
Waiting for a fix.

i believe its because of noise cancellation.
to check it, i tried using ' ok google ' on my home screen. it wasn't picking up my voice.
then i've closed the secondary mic on top with my finger and said ' ok google ' and it works as it should.
this is working even with my phone calls.

[Q] Echoing when talking on Viber/Skype?

Hi all,
I am from Australia and got a sony z3 the weekend and so far it has been great but I am having an issue when talking to people over viber/skype. When using video chat or loud speaker the other person can hear themselves back quit loudly like it is an echo. Even if i put the headphones in on my phone they can still hear themselves back but it isn't as loud.
If I switch to my old samsung s3 it has no problems I am using the same wifi etc same location and calling the same people.
There doesn't seem to be much of a issue when calling normal and using the loud speaker. Just with apps like viber/skype.
Does anyone else have this issue at all? Or can anyone test video/using loud speaker on Viber and letting me know if they have the same issue or is my phone possibly faulty?
Thanks Matt
Try a reboot.
Or try another app. It's possible Viber/Skype doesn't use noise cancellation. You could always use a headset or BT speaker (set it further away from the phone). If that all fails, there's a Mic Sensitivity setting under Settings -> Sound -> Audio Settings.
Thanks for the reply,
I have tried rebooting and it didnt help. I have also tried using headphones and while it made it a bit quieter they still had the same problem.
I will have a go at messing with the sound settings, thanks.
I think i am just going to take it back and see if it is just my phone with the issue or all z3's
Is anyone able to test on the z3 and video call someone on viber and let me know if they have the same issue?
Thanks,
Matt

No sound occasionally when making a call

I have a Galaxy S5 Active and have recently started having a problem. Occasionally when I dial a number, no sound will be output even though the phone is making the call, and the timer at the top corner counts as if the call is working. I'd say it does this about 1 out of 5 calls, I have to hang up and call back and it will work fine. I am not positive, but I think this may have started with the recent 4.4.4 update. I really dont want to restore my phone if not necessary.. anybody heard of this issue?

Maybe it's the front ear speaker issue or network connectivity problem.
Next time you get this problem, see if the loudspeaker option helps to find if the front ear speaker is damaged

I have tried this and there is still no sound even in loud speaker mode. I have also verified that other caller cannot hear me also
I think this issue is with Google play services... Try to search on xda or Google about it. I had read somewhere about it
Tried clearing cache of google play services like suggested in another thread.. but it didnt help
I should also mention that the problem only occurs when I am the one making the call, never when I receive a call

If you have root then try to disable google play services and other Google apps. And check if problem occurs in 2-3 days.

Bad Call Quality - How to Improve?

Hi guys. I have a OnePlus One and I flashed CM13. For some reason my call quality is very bad and callers say that I sound muffled. Is there a radio that I can flash or something that I could do to improve call quality?

Hi, I've had the same issues using the new 00011 or 00013 baseband. I've flashed the 00241 baseband from lollipop which fixed it for me. Here's the link: https://www.androidfilehost.com/?w=files&flid=28032
All credit goes to Chineel for the upload.
I was having all kinds of problems with phone call clarity as were my friends that had purchased based on my recommendation and invite. These problems started around late August/early September. We tried flashing different ROMs, modems, and firmware to no avail.
Then I discovered an obscure post in the Oneplus forums suggesting turning off "OK Google" detection from any screen, and viola! No problems since. Apparently, the always on "OK Google" detection interferes with the noise cancelling microphones on the handset creating all sorts of problems with phone call clarity.
The workaround is to go to the Google settings app. Then dig down to... Search & Now/Voice/"Ok Google" detection and disable "From any screen". It immediately takes affect and the results are like night and day.
Good luck. I hope this helps, and don't forget to hit the thanks button if this works for you like it did for me and my friends.

Mi4, CM13 echo in calls

Hello,
I have a Mi4 with TWRP and CM13, latest nightly from today, but the problem also occured on the nightlies before.
During calls the other party complains about hearing himself. On the internet I found ideas like:
- disabling the "OK Google"-recognition on every screen (although this held true for Skype-video-calls)
- lowering in-call volume
I did not find any other ideas. Do you have an idea?
EDIT: I also tried two things:
1. entering the following things -> no changes
su
setprop persist.audio.fluence.mode false
setprop persist.audio.handset.mic analog
reboot
2. disabling the mic while calling -> success, the other party has no echo anymore
This of course is no useful solution, as normally a mic is needed for calling.
I'm facing the same problem. Did you find a solution?
nope
Same here.
Posted this in another forum. After trying a few things it appears that microphone is relaying sound from the speaker back to the caller. It's like the microphone is too sensitive so it picks up the callers voice from the speaker.
yes, it is definitely a problem with the mic. as soon as you deactivate it, the other party has no echo anymore.
EDIT: I wonder if this is the case, because in the native MIUI there was a noise-suppression and dual-mic option which may be good for avoiding this problem. I highly doubt CM will implement this specifically for this phone. Right now I am always calling with a headset which works fine.
EDIT: Headset isn't working anymore too. Callers say I am way too silent. Soundrecorder App confirms that mic sensitivity is too low.
I think the solution might be here, thought I am not able to understand completley what they are doing there: https://jira.cyanogenmod.org/browse/NIGHTLIES-2619
It should be solved after installing the next nightly:
https://www.cmxlog.com/13/cancro/
http://review.cyanogenmod.org/#/c/139932/
Could someone pls give a feedback after installing it? I switched from nightly to snapshot-channel and therefore am not able to check.

Is the problem still existing with the new snapshot release?
I'd like to know that too! I switched to nightlies now and some people I talked with say it's still there, some don't.

I heard from some guys using latest Snapshot that the echo is gone but when they make a hands free call, the speaker and mic is very quiet/ low. So probably the problem is not totally fixed right now.
I'm on Nightly 13/04 right now, no echo at all but the phone is turning of during call (after I tried to turn on the display). Is there another behaviour on the Nightly you are using?

Samsung galaxy s8 plus audio problem during videocalls

Hello!
I have a major issue during videocalls using google duo, skype where if there are any background noise around me, i can't hear the person i am talking to. The audio cuts off. It has to be silent around me in order for me to hear the person i am talking to. Is there any fix to this problem? I have already reset the phone but the problem is still there.
mic (over) sensitivity? perhaps some will stop by and know the file and file entry to edit.
any of this type setting elsewhere (Settings, the app itself, and sound modification yo have installed, eg Viper, etc... that you can check/get to?
I have no sound modification installed. I checked the settings but there seems to be no part adressing this issue. The same problem happens when i use different apps like skype, google duo and signal. Could it be a hardware problem? The microphone works fine when i record a video or recording audio.
Maybe.
Rooted? If so, and you've done a full, clean install, and sure that the install is working ok, maybe try another custom ROM.
Normal calls work, as I get you it's (just) video calls? Another possibility, I'd consider looking up mic sensitivity and ways to decrease it. On the OnePlus One I am aware there was a configuration file folks could mess with to try and resolve that phone's mics over sampling. That was a common issue for many.
Have you tried turning the volume down and see if that has any effect?
Wish I could offer more ideas, I have used video calls maybe 3 times in 8 years.
The phone is not rooted. This problem occurs only when i use internet based videocalls (skype, google duo). The volyme is not usually high when i call. Thank you for your time, hopefully i will find a solution soon.
Frustrating. Good luck.
