Guys have a look at this thread http://xdaforums.com/google-nexus-5/help/help-camera-sound-nexus-5-horrible-t2776502

There is a fix that works for me.
[Nexus 5 Q&A, Help & Troubleshooting] Wutang200:
That's not a fix! It's a work around that requires root access which voids warranty. Not everyone wants to go down this route.

The issue can only be fixed by Google or LG (more likely LG). BUT they won't fix something they won't acknowledge.

I still think it's a manufacturing defect.

Anyway, the new Android Silver device will be getting announced soon and the new Moto X successor will be announced too. There's plenty of better phones to choose from. This excludes the ugly and horrendously sized Samsung Note phablets!!!

New phone...****y mic

2 days ago I purchased this miraculous phone... In the year 2014 is it posible to exist something like this cr#p? Faulty microphone.. every time I must to repeat, repeat, repeat and finally SCREAM at the mic to be heard, so that people on the street look at me as if I've been crazy!

I have read the entire thread... w#F google lg? Never in my life I haven't occurred with something so elementary/basic... First time lg google buyer...and I was thinking to buy between "now known like crap" and WP Nokia 925 :( . Can't believe what it's happening....first and last time buyer lg or google deaf phones.
[Nexus 5 Q&A, Help & Troubleshooting] dr_stevens:
Found a solution to this problem. Hopefully it helps. But I'm not sure about it - need more reports from Nexus 5 owners.

So, I think, the problem is caused by LTE Mode.

The issue probably persists in networks only not supported LTE. So, disabling LTE mode and switching to 3G mode should solve the problem.

Report here pls. if that was helpful.

WARNING: This is only for non-LTE cellular networks.
[Nexus 5 Q&A, Help & Troubleshooting] markdapimp:
Doesn't work, I've been on set 3G mode for the entire month now
[Nexus 5 Q&A, Help & Troubleshooting] dr_stevens:
So, disabling LTE doesn't help. But people say my voice is clear now. But I'm not sure about it anyway. Moreover, what I did also with my phone, was removing and installing again the sim card for 3-4 times. Perhaps this was the case. But I'm testing now, despite people say all is ok with my calls. And of course before all these operations I did hard factory reset.

Hi i finally found the solution for this problem. The problem with my nexus 5 was occurring mostly in call and after reading your post and dozens others I investigated my self and the way I fixed this problem is by going into root Explorer than going into system and from there into build prop and I changed, dual mic config from '' endfire'' to yes and after restarting my both mic worked in a call. For testing purpose I changed the value back and after restart my top mic was dead and it wouldn't pick any sound but after changing the value to yes and after a restart my top mic works and people can hear me on the other side.

Can the people who try my method write back so I can be sure that I'm not the only one who's problem has been solved.

For my method to work on your nexus you need to be rooted.

Fix?

My girlfiend has a nexus 5 with a dead microphone. We have looked online for a solution and came across this thread.

Today she called google and they tried to rule out a hardware defect by asking her to reboot in safe-mode and check if the sound works properly when calling. And it does!

Now they have to give her a solution to fix this but perhaps someone can test this method to validate it.

Here is how-to-safe-boot:

1. Ensure your device's screen is on, then press & hold the Power button.

2. Touch & hold the Power off option in the dialog box.

3. Touch OK in the following dialog to start safe mode.

I will let you know when/if google comes with a real solution.
[Nexus 5 Q&A, Help & Troubleshooting] Globespy:
Hmmm.... Since it's your first post you can be forgiven for not using the useful thing called 'search'.

Google have a bunch of supposed 'fixes' that they will try to get the customer to try, this is one of them, another will be to turn off Bluetooth and do the same silly factory reset/go into safe mode.

Net net none of their options work. You are wasting your time. The only way to get a true fix is to keep RMA'ing your phone for a new one every month until they get tired and give you a full refund.

The several hacks on here do help, but there's always a compromise/down side. Frankly, for $400 you shouldn't have to compromise on a most basic function such as talking to other people without sounding like you are under water!

Good luck!
[Nexus 5 Q&A, Help & Troubleshooting] jacknicholson:
Having tried all of the usual build.prop mods, including changing 'endfire' to 'broadside', 'false', 'none', etc., the best I can say is that, well, they all kind of work. In my experiences, at least, although they certainly haven't been scientific.

Personally speaking, I'd hardly describe the sound as crystal clear (moreso intermittently perfunctory and often accompanied by a random buzzing/ringing of sorts), but at least I'm mostly audible.

That said, I've currently left the 'persist.audio.dualmic.config=endfire' line alone, and have opted to edit 'persist.audio.fluence.voicecall' from 'true' to 'false'. For no particular reason, to be honest, as each individual edit (or combination thereof) seems to provide, more or less, the same passable but ultimately mediocre result. In the end, I've simply been using a headset or the speakerphone whenever possible.

As an aside, I've found changing 'persist.audio.handset.mic.type=digital' to 'analog' to do absolutely nothing, although others have shared contrary experiences, so who really knows.
[Nexus 5 Q&A, Help & Troubleshooting] allisonfranz:
It's getting ridiculous! To prove a point for a third time, I made a phone call earlier on this evening from a Samsung Galaxy S2 and my contacts I spoke to immediately advised me they can hear me crystal clear.

I didn't mention to them that I had changed phones just to speak to them.

As stupid as it sounds, I think I might have to carry 2 phones with me so I can use one for phone calls and the other for everything else.
[Nexus 5 Q&A, Help & Troubleshooting] Globespy:
I've just ordered my 3rd N5 as this circus continues.

The supervisor said he had never heard of the issue, which I find hilarious.

And I was also told something mind boggling, and whilst very smart on their part gives you an idea of just how slimy this company is:

"Google does not provide a SIM card with any of their phones, and as such they DO NOT GUARANTEE CALL QUALITY!! Any issues you have with call quality should be taken up with your provider".

I of course asked if he knew that this microphone issue has been reported in nearly every country around the world with the N5, and if he still thought it was simply that every telecommunications provider on the planet had problematic networks? He maintained that there's nothing wrong with the phone and it's all the carriers' fault.

The good news is that once you get to your 4th phone (so after your initial purchase and 2 replacements) and the issue is still there, then they will give you a refund. But you have to have gone through 3 devices to qualify.

So when my phone arrives in 2 days, it's going straight back and I'm getting my money back before my 1 year warranty ends which I will put towards a new phone that's not a Nexus. There have been ZERO hardware updates to the N5 and the problem is simply never going to be resolved. Some phones seem to be less affected than others but at some point I am positive that every N5 will experience the issue. The average user will simply put it down to the network, and won't think twice about it.

I'd love to say I was going to buy the N6/X (whatever it's called), but I think I'm going back to Samsung (s5) or perhaps HTC (m8). I love Android, but having gone through hell with both the N4 and N5 I'm just not willing to support their business at least as far as devices is concerned.

PS - any replacement phone at this stage is 100% a refurb. They have entered very specific verbiage on the replacement order email. So you KNOW all you are getting is someone else's old N5, polished up to look new but essentially with the same broken microphone. New box, old phone. Same problems.

"Your replacement device will be refurbished and has been reconditioned to strict factory standards and like-new condition. The device will operate to its original factory specifications."

[Nexus 5 Q&A, Help & Troubleshooting] Wutang200:
I've found something out that is very interesting indeed!

A couple of my work colleagues bought the Nexus 5 and I immediately advised them of how rubbish the phone really is when it comes to call quality and video recording. I even emailed them with specific tests to try out to see if they're affected by the same issue as here. I strongly advised them to get another phone due to these manufacturer defects.

Once their phones arrived, they both said their phones work perfectly fine when making phone calls to people as well as recording video. They could have returned their phones as part of their cooling off period if they wanted.

The only thing I've worked out from all this is that they both purchased the N5 through mobile network providers instead of buying them through the Google Play Store. I'm beginning to think the phones provided from Google Play are somehow different to the ones they provide to network carriers.

Can anyone else check this out somehow?
[Nexus 5 Q&A, Help & Troubleshooting] monkeypaws:
They're not. They're the same. And also I've owned my nexus 5 purchased from Tmobile almost half a year and have never had mic issues. Actually. I've had two. None whatsoever. So either some of you are super unlucky and getting bad batches or are super picky which I'd say go to another line of phone.
[Nexus 5 Q&A, Help & Troubleshooting] Falysix:
Is there any fix now ?
[Nexus 5 Q&A, Help & Troubleshooting] chdloc:
The Nexus 5 seems to suffer from unoptimized dual microphone processing, which is used in the call and camcorder use cases.

It is also possible that the dual microphone processing is too sensitive to hardware tolerances when dealing with the signals coming

from the two microphones. This would explain why people seem to experience different level of problems when making cellular calls

and/or using the camcorder.

If you are having issues with the audio quality of camcorder recordings - and have a rooted phone -

I suggest you take a look the mod discussed here

[Nexus 5 Q&A, Help & Troubleshooting] bblzd:
There's no differences. Most phones just work properly with no noticeable mic issues, as we've been trying to tell you all along.
[Nexus 5 Q&A, Help & Troubleshooting] Wutang200:
There must be a difference as that's what made me return my N5 11 times!!!

There is definitely something defective about this handset!

My Moto X has been solid for call quality with the exact same SIM card within the exact same conditions!
[Nexus 5 Q&A, Help & Troubleshooting] bblzd:
I'm glad to hear your device is working as expected. Just try and remember your case is not typical, in almost a year you're the only example in this thread of someone who was never able to make a working call across multiple devices. That should tell you that it was an isolated issue with your situation and I've offered some theories in the past so I will avoid doing so again.
[Nexus 5 Q&A, Help & Troubleshooting] Globespy:
If you experience these issues (I'm on my 3rd device), know that the best way to resolve it is to keep getting a replacement phone. Google will not send you 11 phones. If your 3rd handset had the same issues when you call to complain they will refund you. They won't send you a 4th phone. I'm about to begin the refund process and be done with this device. I was going to ditch the Nexus program, but if Motorola is the next phone manufacturer then I know that phone calls will work!!
[Nexus 5 Q&A, Help & Troubleshooting] Wutang200:
I was able to make the phone calls, but no one could properly hear me. It sounded like I was very far away from my handset and like I was underwater. Also it would disconnect often and wasn't very stable. Mine was definitely not an isolated incident.

Anyway who cares, the Nexus 6 is around the corner to help us all forget about this defective handset.

[Nexus 5 Q&A, Help & Troubleshooting] danarama:

[Nexus 5 Q&A, Help & Troubleshooting] 350Rocket:
For me the fix was to turn off the noise cancellation, and then turn the call volume down enough that it doesn't cause an echo. Not a perfect solution considering my old HTC desire makes perfect phone calls but I can now carry out decent phone calls every time. Maybe not good in noisy environments though.
[Nexus 5 Q&A, Help & Troubleshooting] :
To make such modification you need root access right? I have a dumb question: If I root my phone, will I be able to get android OTA updates normally?

=S
[Nexus 5 Q&A, Help & Troubleshooting] :
Yes, but after OTA Update root access will be lost iirc. Check out Apps like RootKeeper or root again manually after OTA. Bootloader will remain unlocked after OTA.

Oh... Important. Undo all build.prop changes before OTA. Any modification like xposed will break OTA.

I got a fix (loudspeaker helped)

I just received my Nexus 5 a week ago and i had problem with mic in default calling process and in others calling related apps ( Skype ).

I worked a fix for myself ( at least ).

I made a random call to one of my contacts (I were testing a microphone out then) and I pressed for a loudspeaker on my nexus. And even after i disabled loudspeaker, microphone still kept working.

I previously tried to take out the headset/headphone from the audio jack and put it back in, even tried to disable MusicFX (which was disabled when i made a loudspeaker test).

I hope someone from here gets it fixed just like how I did. SO Good luck to everyone here, with a same problem.

Garbled Calls

Hi all, new to post

I am getting recurring issues when sending/receiving calls,

both yesterday and today the call becomes garbled at both ends.

Sounds very similar to a dial up connection, if you have ever held two phones close together that is what it sounds like.

Also re-calling remedies the issue temporarily,

However unable to remedy this and does not happen 100% of the time. I have not flashed or used audio recording

Currently running android 5.0 with a Sprigen case, could this be a noise cancellation / microphone issue ?
[Nexus 5 Q&A, Help & Troubleshooting] jpchopper:
I had the same issue. Voice search, calls, all media volume (but not ring or alarm volume). Flashing a new zip didn't fix anything, but a complete stock image flash from fastboot worked. Mostly.

This week it did it again, and I no longer have a computer available. Same problems, installed new ROM, no luck, used Flashily to put stock recovery back and wipe cache... still no good.

Finally, I plugged in a headset, (which worked) rebooted the phone with the headset attached, then removed the headset.

Problem went away.

Merely speculating, but it seems as if the phone on some level starts acting as if a headset is connected, and needs to be gotten out of that.

Hope this helps someone!

[Nexus 5 Q&A, Help & Troubleshooting] deamonix:
This is an ongoing issue, that I think is being masked by the simple fact that the majority of people don't actually use their phones to make calls any more. Using any BT headset or car hands free masks the problem, as well as those that use their phones just for net access. I have already RMA'd my device ( 32 GB Black, batch 311K ) and the issue is still present, even with no additional apps installed.

This only happens for me when using the stock dialer. If I use any VOIP app with noise cancelling enabled it works just fine.

This is one of the original threads reporting the issue, but it isn't getting much attention from Google.
