is there a way 2 amp the mic up? by alot . maybe in the buildprop??
Are you sure your mic is broken? Maybe it is just water stuck in there - it happens to me sometimes when I clean my Defy. Usign compressed air to get rid of it.
Wel do u open it up then?

Best thing you can do right now is open you defy and disassembly it. Dry for few ours nad assembly it again.
If it won't work, you have to microphone module or use your motorola phones

Ok, so.. i have this broken microphone on a hd2 board and need to replace it. But.. the microphone is soldered to the board + a metallic shield over it, also soldered to the board.
I removed the original (broken) mic and the shield and noticed it has 4 contacts to the mothebroard. I don't know if it's a digital mic, or what type of microphone is it. I soldered a couple of wires to that spot and placed an external mic to test to see if the board is fine. It worked, but i had a relatively low gain on the microphone. I tried to solder a nokia mic inside, but failed because i heated the mic too much (microphones and heat.. not good buddies). I cannot fiind a direct compatible mic so i need to improvise something.
Does anyone has an ideea about what types of microphones htc uses on hd2 or similar phones? And how to safely mount it on the board?
hd2 mic replacement
Hi Bogdan. Can you please share your experience with the hd2 mic? I have the sae problem after keeping a hd2 board in isopropilic alcohol after the phone took a bath. it works fine noww but the mic has very low gain and I think it's diafragn was destroyed (or at least the glue) by the alcohol. I would like to change it to some other mic, but after I red what you wrote, that it has 4 connections i'm in doubt. Did yu manage to make a "transplant" and have ot working? Also, I have a problem with the screen orientation (internal gyro sensor ) meaning the screen won't auto rotate after i removed the metallic band from the bottom of the screen, that connects the front to the bottom of the screen of smth like this (GND). Have you seen that problem? Problem is it works normally on Windows mobile but doesn't on android.
Thanks.

So today I accidentally dipped my phone in shampoo ( a bit hard to explain right now). The only noticeable damage is that now my phone is stuck in headset mode. It is easy to see how this could be of inconvenience.
My question would be if there is a such app that would allow me to manually switch between headset mode until I figure out how to fix the issue.
All the help is appreciated.
Thanks to all of nobody who helped. Left my phone alone and switched to a nasty blackberry for a day, when I came back, it was fine.
This thread can be closed.
The headset mode is chosen by the connectors in the headset jack. Try cleaning it out carefully (powered off) with a little bit of alcohol on a qtip. Make sure you give it a while to allow the alcohol to evaporate.

Hi there
I keep my Nexus in my front pocket while listening to music on my way to work every day. This seems to put a lot of stress and tension on the jackslot/plugin, especially when I sit.
And now it's broke... again. It's my 3. phone that this has happened to.
When I plug in the jack, there's only sound coming from my right earbud, but when I gently twist and bend the jack, the left one works for a second, but thats it.
I've removed all dust and such from the jackslot, and it ain't the problem. I figure it must be something to do with my phone's hardware. (Same problem with different earbuds/jacks).
Does anyone have any ideas how to fix this without having to send it in for repairs?
Sounds like an hardware fault. Use a Bluetooth headset

Hi,
My Defy+ (MB526) does not have any sound when playing back audio files (Music) nor the ringing sound can be heard when the phone rings.
I am certain, the "external" speaker is dead. However, where exactly is this external speaker located?
Initially, I thought the ear piece speaker is the same thing, so I purchased a couple of spares, opened the phone and tried to replace it. The internet have lots of instructions on how to replace the "ear piece speaker". Obviously that didn't work, nor can I see anywhere on the electronic board a thing that looks like an external speaker.
Pls help me... It's confusing.
Thanks in advance.....
im on the same problem

Thanks! I see it now.
I managed to separate the board from the rear housing. (I needed to remove the sim and the SD card and it was easier to separate it, not sure if that was indeed true)
Once I can see the speaker part (looks different and also larger than ear piece), I finally knew which part to purchase from eBay.
Thanks again!
Hey there everyone!
As my title says, my proximity sensor has gone crazy! It is of course a hardware problem but i need some help here! 2-3 weeks ago, i dropped my nexus⁴ in a bowl of dal , upside down (the phone's upper portion was affected only, the lower one was intact). For some hours the earpiece didn't work properly but the proximity and ambient light sensors were working properly and so were the camera(front and back both) and flash! Whenever i tried calling someone, the earpiece didn't work BUT as soon as i plugged in my earphones(with mic), i could hear and respond without any hiccups.. I thought it might be due to the phone detecting that there's an earphone already plugged in (before it was plugged in) to the phone , probably because the earphone jack got some dal (liquid) stuck in it. Anyways, i tried finding a solution for this and then i installed "SOUNDABOUT", an app which changes the way the phone's jack and earpiece and speakers behave (in short, controls what does what and media and phone call output) . I set the phone call audio to "earpiece" and media audio to "speaker" which works great and which solved the earpiece problem for me but now whenever an object comes in range of the proximity sensor, the screen turns itself off and turns back on as soon as the object is removed. This is making me crazy. However, when i switch the phone call audio to "earphones with mic" and restart the phone, the proximity sensor works fine but then no sound from the earpiece.
NOTE: When i restart the phone, for 2 mins or so, everything works flawlessly and works like it is supposed to, but after that it starts malfunctioning(maybe some service is causing this malfunction? )
I need your help with the following questions
1. Is it a hardware problem? (Since, the jack and sensors are one hardware unit)
2. If it's a software problem , can it be fixed without reinstalling the OS?
3. If it's a hardware problem, will i have to replace the jack unit?
Oh, and btw i am using Paranoid Android 4.6 BETA1 and Faux kernel.
Thanks!
Dal? You got goop in your phone. But it still sort of runs. I'd take it apart, take out the battery, then use the highest alcohol content you can find and rinse out the phone use at least 70% alcohol

It's a nexus⁴ -_- doesn't have a removable battery.. Phone is working perfectly...if you have a solution, please tell but don't crap the thread...thank you
if you don't know how to remove n4 battery - doesn't mean that it's not removable
and about your problem - as jd1639 suggested, try to clean mainboard, especially proximity sensor/ headphones connector area and maybe sensors itself

I know how to take apart the n4 and remove the battery and all but haven't done it before...maybe ifixit guide can help?
So should i open up my N4 and clean the sensors and the jack...i don't think there's anything wrong with the sensors as they work perfectly but the only glitch is they work all the time
Nevermind guys! I fixed it! all i did was turn off the sound about service and it's working flawlessly! Thanks a lot for your help anyways!
Just open the phone and remove mainboard to clean it with isopropyl alcohol. Don't wait until corrosion damage it completely . Also not bad idea would be take a look at sensors/headphone jack assembly ...
