[Q] handset microphone doesn't work well, speaker mic works fine?

This seemed to only recently have come up.. but the handset microphone does not pick up sound nearly as well. It is maybe 1/10th the amplitutde. I've tested phone calls to myself (to GVoice headphones, other phones, etc.) and the speaker mic works great. When you take it off speaker mode it barely picks up sound at all.
When I use Evernote voice note recorder or a simply voice recorder I get similar results of extremely attenuated sound.
I do not _believe it is a CM10/custom ROM issue as this new behavior seems to have only started recently (past 2 days?) and was running the same stable ROM the whole time. I haven't yet isolated, but it could be a bluetooth problem (doubtful) - as I recently paired with two devices sometime in the past 3 days, or maybe some App has taken control over the amplification of the handset microphone.. but I install/uninstall so many apps to test throughout any given day this would be hard to isolate.
Has anyone had this issue before??
I'll go ahead and reset to a clean ROM, stock ROM, etc. and see what results I get, but I wanted to post a Q first to see if anyone ran into the same issue. Thanks in advance!

[Q] Nexus 5 w/ OmniROM + franco mic issue only during call

Hey guys. I'm having an issue with my microphone during calls. People say that they hear me very soft, as if I'm on speaker phone and far away. Other times they can't hear me at all, just a lot of weird interference. I tried calling myself using a VOIP app and left myself a voicemail and I can't hear a thing regardless if I'm using speakerphone or not.
There is NO problem when I'm on a call using bluetooth in the car. There is no problem when I use any voice recording/google now/swype voice recognition type app. Video recordings also work fine.
I'm using the latest OmniROM with Franco.Kernel. I can confirm that the problem also persists when I use the OmniROM kernel.
Could this be a software issue? I'm concerned because my screen has a crack in it and I'm not sure if Google/LG will cover a microphone issue under warranty because of the cracked screen. (I can also confirm that this problem existed BEFORE the phone fell causing the cracked screen).

So I confirmed that this is not a software issue. I went back to stock everything and the problem persists. I opened it up to see if I could do anything to the mic itself, but it's attached to the board and there was nothing I could do. At this point I have a phone with a disfunctional microphone and a voided warranty due to a cracked screen. This sucks. Is there any software that will let me switch which microphone is used during calls? Again, the mic that is used for voice recognition and video recording and google now and voice recording and all that stuff works. The only mic that doesn't work is the bottom mic during calls. Can I switch it so that calls go through the other mic? it won't be perfect, but better than nothing.

[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

Mice issue!!! (only phone calls issue)

On my phone,graet when I'm making a phone call the person on the other end can't hear me clearly and it becomes clear after using the speaker (I mean isn't it the same mic?!) And this doesn't happen all the time (sometimes it's just clear sound without using the speaker and the mic is wotking just fine when using viber & facebook calls or just recording anything). It has to be a softwarsoftware issue. right?!
I just bought the phone and I haven't had the chance to compare mine before and after the 38R update because I just bought it and updates were raining dogs and cats.

Please, help, my microphone is VERY quite!

Hi, everyone. I have Lenovo K900 Android version: 4.2.1. Recently I changed the battery since then my mic hasn't been working during phone calls, both regular calls and on WhatsApp. Although it works perfectly when shooting a video, making an audio recording, voice searching etc., only during calls. It's not completely broken if I shout right into the mic the receiver can hear me
very badly (as if I was talking underwater or from very far). Other things to point out:
1) I can hear people well, so there is no problem with my speakers.
2) Using speaker (in order to enhance the mic) during a call doesn't help at all.
3) It has a very problematic back cover, so it took a lot of physical effort to open it, so my suspicion is that mic could have been damaged, though it seems unlikely since it works very well outside the calls.
4) Using a headset mic during phone calls works perfectly.
5) I don't have a warranty.
Some things I've tried so far to fix the problem:
1) Hard reset the system (twice), both normal reset and hard reset (thus deleting all the apps, so I'm doubtful, it could be a software problem)
2) Turned off "Background Voice Cancellation" and put mic quality to "bright".
3) Turned off "Ok google" voice option.
4) Made sure that it wasn't my fingers covering the mic causing the problem
5) Rebooting the system multiple times.
6) Using headset during the call, ending the call with headset on and only then taking it off in hopes to reset built-in mic settings.
7) Downloading "Sound About" app.
None of these options helped, even slightly.
I really believe that it's fixable since the mic works everywhere apart from calls, and even there it works, just unbearably quiet. I have one last idea left, which is to change the Android version completely, maybe upgrade it. Please, if you have any ideas, respond, this bug is driving me crazy. Thanks, everyone, in advance for your help!
