[Q] Microphone Problem - Defy Q&A, Help & Troubleshooting

Hello!
I have the following problem with my Defy (red lens).
When I turn on the speaker during a phone call, the microphone on the front of my defy becomes very quiet. Logically the microphone should become more sensible, because usually you turn on the speaker to speak free, without holding the Defy at your ear. But what happens is the opposite: it becomes less sensible. On the other hand, I discovered that the rear microphone becomes more sensible when I turn the speaker on.
Is this normal? Does anyone have the same problem?
The microphone (at the front) of my defy seems to be fine, because I can make very good recordings with the app tape machine. That's why I think it is a software problem. I have a red lens Defy and I have this problem with MS2Ginger, MIUI and a Defy+ Gingerbread Rom.

Hi!
Are you sure it's a software issue? As I read this there were modells with hardware bug.

Loudspeaker microphone problem

Hi all,
I'm having a problem with the internal microphone when trying to use the phone handsfree without a headset. Basically if I turn the phone onto loudspeaker, even if I hold the phone right up to my mouth people have a problem hearing what i'm saying. The microphone works fine if i don't have the loudspeaker on, even when i'm holding it a good few inches from my face but as soon as i turn loudspeaker on, the microphone seems to stop working very well.
Is there anyway of correcting this problem as it seems more software related than hardware...

[Q] Speakerphone on D+

Hi There!
We have a defy original and the speakerphone is basically completely unusable. I have been told by the company I bought it from that it's because the speaker microphone is half duplex.
Does the Defy + have the same crappy speakerphone?
Thanks.
yup!
I only had issues with the ear-piece speaker, it started to crackle and fail eventually, but it was covered by warranty

[Q] What's going on with my in call sound?

Hi,
I have unusual problem with my motorola defy earpiece (or at least i think it's that). Bought it used, so don't know how it was before...
During calls the volume of earpiece speaker is very low, practically unusable unless you are using phone in completely silent environment. The weird thing is tho, when i turn the phone around and listen closely on the back side the volume is actually a bit higher - seems like in call sound is coming from big phone speaker on the back, just very silenty... When turned to loudspeaker mode during call - everything works as intended, i can hear loud voice on phone's back speaker. I know that people are having problems with defy's earpiece not working at all, but it's not like that for me. It actually seems that both speakers (earpiece and main speaker) are working during calls just on very low volume. No luck searching for help on internet, doesn't seem that anyone had this happen... Problem egsisted with stock ROM, so i installed CM 7.2 - nothing changed. Volume buttons work, but even max volume is just too low. Wonder if that could be software problem or the hardware is somehow ruined? Any ideas? Don't know where to turn - i'm intending to take phone apart and see what's going on in there, no previous experience so please stop me
I just got my defy today and have exactly the same problem. I flashed cm 7.2

Defy+ Very Low incall volume

Hi All,
Recently I replaced the LCD screen of my defy+ phone. However after replacement mic volume has decreased a lot. In call, other party can't hear any sound. I checked all the rubber parts (yellow seals) & can confirm have placed each of them in place which packing back.
However if I switch to speaker mode incall, mic volume increases again.
I have tried various ROMS right from flashing original sbf to latest 4.4 ROMS.
Please can any one help or throw any light on this.

[Q] Mic issues

Has anyone dealt with a dead mic ?
One day out of the blue on 4.4 mic stoped working.
Installed L 5.1. beta 3 and the mic still seems dead (Calls and Google voice) HOWEVER in sound recorder the mic works (picking every single sound) ...
Further more installed the HiQ Mp3 recorder which apparently can use front and or back mic and it works in all configs .(front back and stereo)
Tried different values via engeenering mode with no luck ....
****** Apologies to all this post was misplaced in this forum *********
I guess I should replace the charging board alltogether however I am puzled that the recordings come out clean ......
Anyone with a similar experience ??
(btw sound on wired headset is fine ... bluetooth sound is broken I think due to beta since the bt headset and speaker I tried didnt work)
Phone is Jiauy S3A
Ok Results
The issue was a dead mic (low mic) or rather a near dead mic.
Replacing the mic (on the same board ) resolves the issue (note that you can use third party mics i used asamsung one)
Best test to realise where is the fault
Open the camera recorder and start recording
Close the top mic hole with your finger, start talking in the lower mic and in the end gently (very gently) blow towards the hole.
Repeat on the top hole with the lower hole closed
After that listen to the video
If there is a problem with a mic the voice might be heard but the blow will be almost inaudiable in the problematic mic.
I have exactly the same problem - mic works fine on sound recorder and on the video camera, but Google Voice Search and using the phone does not (I've tried your blow test and it's all fine). This surely cannot be a hardware fault, can it ?
I've tried updating to LL5.1 beta3, but same problem. I've fiddled with the audio settings in the engineering menu, using a variety of values, and turned off the noise reduction without any success.
Any ideas ?

Click to expand...
Click to collapse
Google voice was the main indicator that the mic was bad ....
Do the blow test again and try as "gentle" as possible and then compare the results, if the uper mic is louder then then mic is dead or nearly dead.
Most probable that you ll need to change your mic
Thanks for your help - can you provide a link to the replacement mic you used (or did you use one from an old phone) - and is it easy to replace ?
Unfortunately I did go to a service shop for the repair, so I dont have a model number, all I know is that he proposed two different types, one was a noname and the other one was made by samsung (so my guess is that any samsung service center can sell you one) .
The process took about half an hour, unsoldering the old mic and soldering the new and the cost was 10 euros ( around 11 USD)
Sorry I couldnt be any more helpfull on that.
I found that, after video recording with stock camera app, main mic stop working for calls. only upper mic working. you can test it with 2 phones in both hands. but I was find simple solution: many people holding phone when taking pictures so the controls are on right side. but if you turn you phone so the shutter button will be on left side, after video recording, main mic still working!!! btw. if you like to take a shoot with control button on right side, just after you finished, turn your phone for 180° and make one more shoot, just to save your main mic for calls. no reboot needed after this action. tested on many roms, KK or LP, happend with all roms and stock camera. so problem is with stock camera app and sensor that give the information to phone to disable main mic.
Well mine was definitely a hardware fault - got a replacement lower board (USB/mic/speakers) and replaced it myself - all good again.
I think i've got the answer. The lower mic is broken for some of us. When we got to the camera app and take a video and turn the phone around it will indeed change the mic and then will use the upper one (still working) in future calls. This is why you can then be heard after when you call someone, but you'll be using the upper mic and the lower mic is still broken. Once your reboot you have to redo this. I'd like to buy a new board (usb + mic) but we cannot find any on internet anymore. Except some sellers on Ebay who are selling it from 150 dollars to 900 dollars (no joke). I guess i don't have much solution except doing that trick and use the upper mic and then try not to reboot the phone.
