[Q] Mic not working - Galaxy Nexus - Samsung Galaxy Nexus

Hi, I have a Samsung Galaxy nexus. There has been no physical damage or any exposure to water. Although I had dropped my cell phone a few months back which cracked my screen at the bottom-right corner( did not damage the display). Suddenly today the mic isnt working. When on a call the other end do not hear a word neither does any voice recognition software works. but when i switch on to loudspeaker the other end can hear my voice . similar is the case when i plug in headphones. I tried flashing and also did a factory reset. Nothing happened.
I am really worried as to what is the issue. Do is consider replacing the mic strip? Is there any cause behind this? I am not ble to figure out whether its a hardware or software issue . Please HELP.

Problem: Speakerphone always on... always.

I had a strange problem on Sunday where my phone was constantly sending the * non-stop. I tried powercycling and yanking the battery, but it was relentless. The key was still 'clickable', so I decided to disassemble the device and clean the key sensor. (I had disassembled it a while back to replace the screen, so I wasn't intimidated by this procedure.) I used one of the guides on youtube to take it apart, I gently cleaned the sensor with a qtip and reassembled the phone. And it worked! No more stuck keys
Now though, I have a new problem. All conversation comes out of the speakerphone. I can turn the speakerphone on and then off, warm boot, cold boot, yank the battery, adjust the volume properties, I even reflashed the newest Ricky 6.1 rom. Still, I get all audio out of the speakerphone. As far as I can tell it also is coming from the ear speaker, but the speakerphone is loud enough that I could just as well be hearing it instead.
The question is, is this a short? I'd have a hard time seeing it to be a s/w issue after I reflashed. Does anyone have any ideas what I'm facing?
bump.
I realize I'm posting a probable hardware issue to a primarily software forum. I wasn't sure where else to go. If anyone can suggest a different forum that I could post the question at, that would be equally appreciated.

i have same problem please help
take it to service - HW fault .. or if you wish to open device I can tell you what the test points are
I agree with JSP_M
You didn't have this problem before you opened your device. You have the problem now, since you have opened your device, so that obviously means that something went wrong when you opened it.
The audio output is one line. It diverts the signal to the earpiece or the speaker. These diversions are controlled by your registry, since you have reflashed your phone, the registry will have been cleared, so that is not the problem. Plus, you claimed you hear sound in the earpiece at the same time you hear sound in the speaker, so open up your device.
Trace out the lines from the speaker and the lines from the earpiece, if you feel froggy. Then, see if anywhere that shouldn't be touching is, or if something looks brown or discolored. This indicates a short circuit. I can safely tell you though, that something is touching somewhere that is not supposed to be. Listen to JSP_M, he sounds like he has some other points of interest for you test, once you get you phone opened up.
Hope this helps. Later.

Try to call the customer service line from Tmobile and tell them your phone is defective and they should send you a new one.
The loud speaker is harnessed in the back housing of the phone and the ear speaker is harnessed in the faceplate above the LCD. The pads that they connect to aren't even close to each other and are on opposite sides of the mobo. I have repaired a lot of Dash phones and I have yet to come accross this problem. Try cleaning the pads they connect to and make sure the contacts are making a good connection. Or, if you can live without speaker phone then just remove the speaker from the housing all together.
I'm having the same problem on my Wing (Herald). But I never took it apart. In addition Activesync will no longer work. It never connects but my computer makes the 'ding' and the PPC screen lights up when I connect it so it can't be a bad usb port. It seems like a software problem to me, since it recognizes being plugged in, just not the connection.
What are the registry keys that route the audio?
how can i edit register keys
and i get new ear speaker still same problem
thank you
Send it to customer service
I once had that problem.... I sent it to customer service, and i got a new phone in 3 days. You have to pay for shipping though.

My Galaxy Nexus produces a pop/crackle noise time to time

Hey,
It seems it only happens when sound is out after absence of sound through the speaker.
I don't know much about hardware, but I guess it happens when the speaker is internally turned on again?
I can easily reproduce this when chatting with someone. All I gotta do is not type for a couple of seconds and start typing again and the speaker will produce a very brief pop noise at the exact moment when the keypress sound effect is played.
I just got my replaced Galaxy Nexus and I don't believe I noticed such problem with my old one.
This is my third replacement and each devices had errors of their own.
Do you think this is yet another hardware defect? Can I fix this through any software fixes?
Ideas, anyone?

vzw galaxy nexus static during call

OK..so here it goes... When I try to make a call all I hear is ridiculous static... This is through the earpiecec, wired headse, BT headset and speakerphone.. This has happened on multiple roms, kernels & radios... What's really weird is that when I use Grove IP it works fine... Ive searched & searched & can't seem to find a solution... I just returned the phone to 100% 4.2 stock (jdq39) & the problem persists... This all leads me to believe its hardware related... I guess my next step is to take it apart... If anyone can point me in the right direction or tell me what I should be looking for when I take it apart it would be GREATLY appreciated!!
I just finished replacing the screen on my GNEX after a bad drop and water damage. Everything worked except for the earpiece and microphone having static during calls. Strangely though, unlike in your case, it's crystal clear on speaker phone and with a head set, in both directions (they can hear me and I can hear them). I have even replaced my earpiece, leading me to believe something on the motherboard is fried.
Thankfully, it's only a backup phone/media player at this point.

yeah...Im starting to think that maybe my problem is the antenna that recieves signal from verizon... since Voip calls work fine & when I make a call using verizons network I get static through earpiece, speaker & headsets as well... Im trying to do as much research as posible before I go craking the phone open and poking around inside... Im just using it as a media player now like you but I really wanna fix it! Its not a bad phone and dev support is still strong... Thanks for the reply by the way...

Up speraker - earpice not working Hardware issue

Hi my up speaker earpiece not working well. If you push ( not strong push almost touch ) with your finger the up section of the phone the speaker not working or make strange noises or plays in low volume .

Sounds like a defective device. You could try sending it in for a replacement under warranty.

Nexus 5x low microphone volume!

Friends,
I have noticed that most of the people that I talk to with my nexus 5x, ask me to speak louder!! It usually happens once or twice during the call. I think the volume drops to half at some points during the call! It has never happened with my other devices!! My nexus 5x doesn't have any cover and screen protector and the microphone is unobstructed! Is it a universal problem or am I the only one affected.
I am on stuck, unrooted, 6.0.1, march update!
Is there anyway to increase the microphone gain?
Thank you in advance
Do you have headphones connected? I think that the 5X uses a different microphone when headphones are connected vs. not connected. It's rather frustrating, I wish it would use the same one.
Having same issue with two phones I bought.
Any update on this, it started on nougat update for me galfren (fully stock) . My one still on marshmallow, work fine
I am having a similar problem. my case is not covering up the microphone but people always ask me to speak up. It is really frustrating coming from my galaxy devices that I could lay on the couch with the phone on my chest and carry on a normal conversation. With the nexus if I turn the phone slightly away from my check they hear nothing. I doubt they will give a warranty phone, but right now it is enough for me to never buy an LG again.
you could root your phone and install a custom kernel inck. kernel manager to adjust volumes such as microphone.
