[Q] Very curious Nexus 4 defect (in my opinion)

Hi!
A few weeks ago my Nexus 4 fell down and the front display cracked right under the camera.
At first there was no problem and the crack wasnt disturbing. But since last week my microphone doesnt work properly anymore.
It doesnt work in several apps (Skype, Teamspeak, Google Voice Search) and also not when Im trying to make a phone call.
I can only take a phone call when Im turning the call into the "speaker mode". So then the caller hears me but everyone around me hears my call..
The support says that it isnt a warranty case because I let it fall down. But I cant imagine that the microphone is defect 1 month after it fell down.
Also I think that the german support engineers are not the best educated ones because they have so many devices to analyse.
Do you have any ideas?

The mic probably got misplaced from the pins when you dropped your phone. You have to open the phone and place it in the right place

The mic is broken so you can't talk. Nexus 4 has 2 microphones and maybe the 2nd one works on speaker mode
As denpei above said here, the other mic will probably function when you're in speaker mode.
In that case your phone has to filter out the voice of the one who's calling you from the speaker, since its a noise cancellation mic.
There's no defect. You dropped your phone and you broke your screen and the mic. Duh, put two and two together. :good:

Yeah in Speaker mode i can call normally like i said above.
Is there a tutorial how to replace the microphone? I only find some teardown videos
EDIT
Ok i found a video where it is shown where the main mic is. And i found a way to replace it if its really broken.
Thanks

S7 Edge - Microphone not working in calls

Please help,
Samsung have returned my phone twice saying no fault found, but every time I make or receive a call there is no sound on the other end. The mic works for google search, video recording, voice recorder app etc, but as soon as I make a call no one can hear me at all. Any ideas welcome please before I end up selling it as faulty. Gutted and tearing my hair out!
Hey!
I have a similar issue with my S7. Microphone does not work only during the calls. Turning on speakerphone does not help (as it should when you have a broken bottom microphone) and also if I connect headset then the microphone from the headset works. In all other aps both (botom, top) microphones work (I do have stereo in video recording etc.). Did it happen to you after system update or when?
Cheers
A small update:
I have found that the issue is even more silly for me.
So I make a call and the person to whom I am calling cannot hear me. Then I connect a headphones, but ones without a microphone. And suddenly the microphone in the phone starts working. But the moment I disconnect them it stops.
Can you confirm this happening for you?
its old, but i have same problem. Now, I am trying to flash stock rom and see if it will work. After restart, I microphone works only once in call app, that it dont work. But i can record audio with it and in any other app it works. Idk what is the problem, but i want to find out

microphone not working during calls

Hi everyone i have Jiayu S3 (lollipop 5.1) my microphone stopped working during calls. I can hear the others but they can't hear me. I've tried switching to speakerphone and back, and toggling the mute button on and off during the call, but no luck.
But when i use sound recording its work perfectly so i noticed that my phone has two mics one for recording,videos... (work) and one for phone calls (broken) i think the second of these is broken so is there any fix for this issue or is there any app to switch microphones and use the first mic instead of the second one
Hi, I spent countless hours on your same problem, and I hate to be the bearer of bad news but here are my personal findings from my post about 9 months ago:

Microphone issue

Hi, i have my S8 for a week now
but yesterday
i noticed that the mic stoped working, the recorder was the last app i used.
i have made a factory reset but no change,
the fix telling that dust was the problem seems not to professional about it
so a launched the sound recorder again then i tried a call and it worked back, the recorder asked about authorisation and i think it was the real issue
mic needed authoisation but no notification and the phone app / dialler only wasn't working.
but now it's ok again
please a confirmation will be great from other owners / users of S8

[X00TD] Mic not working in loudspeaker

Hi guys,
My phone got into water recently, but luckily after going to local repair guy it works.
Only issue is, my secondary mic hardware is gone. So when I am on call and turn on loudspeaker, Other person can't hear a thing.
I tried to do some changes in build.prop so that always my primary mic is used but was unsuccessful.
Anybody knows how this can be achieved ?
Or if someone can give me reliable link of mic part online that will also help.
Thanks
