Microphone problem in my Redmi Note 3 - Xiaomi Redmi Note 3 Questions & Answers

Greetings everyone,
I had bought a Redmi Note 3 a couple months back. The microphone was perfectly fine at that time. After the MIUI 8 update, I am having a lot of issues with the microphone. When I call someone or vice-versa, I can hear them but they cannot hear me. People complaint that all they hear is static. When I restart my phone it starts working again for half to an hour. I even used the sound recorder but all I heard was pure static. A tap on the microphone gets it started everytime. I tried CIT and it doesn't work until I tap on the microphone. The tap isn't too hard nor too light. I thought the problem was with the MIUI8 and unlocked bootloader and flashed CyanogenMod 13 to see if it gets fixed. Now I hear static plus a little of my voice. When I shout right near the microphone, I can hear my voice but very lightly, along with lots of static. Is this a hardware or a software issue. And can someone tell me any way to fix it?:crying:
Edit: Just noticed that even though I can hear a faint sound of mine in sound recorder when I shout into the microphone, during calls people can't hear me. All they hear is static.
Thank you
Regards,
Sriram
Device: Redmi Note 3
Bootloader Status: Unlocked
Firmware: CyanogenMod 13

well, easiest step would be to go totally stock ... normal MIUI without anything fancy.
if the problem persists -> hardware issue
if problem is solved -> software issue

Thank you very much for replying. Although, I have already tried that. I went to cyanogenmod, then back to MIUI and then I even downgraded to check if the problem is there, after which I came back to cyanogenmod. The problem is always there. Its happening to a lot of redmi note 3 phones. Also, when I record audio I am able to hear my voice, but its very faint. There is a lot of static cutting it. Also, I had unlocked bootloader the unofficial way and had rooted it too. I did it the unofficial way because after I got permission from MIUI to unlock bootloader, the software to do that was constantly giving an error and was stuck at 50%. So due to this reason will my warranty get void or it will be good? And should I take the phone to the service center with cyanogenmod or MIUI and lock the bootloader and unroot it?

so youve been at the original stock software and the problem was still there?
then i believe its hardware related.
as you hear a bit of a sound ... maybe something blocks the microphone? ive watched severall dissasembly videos and it seems to be easy to take the back housing apart. i would do that, check if the microphone seems to be fine and test audio with the back housing apart.
in case you want to go to a service center i can only say what i would do.
i would get the phone as stock as it could be ...

Yes I was at stock and it was there. And I don't think I can remove the back housing part as doing that on redmi note 3 voids warranty and they charge you money for it and return the phone without any repair lol.
Anyways thank you very much. I will put it back to stock rom, relock the bootloader, bring back the old recovery and remove root and take it to the service center. Thank you for taking your time to reply. I really appreciate it.

And on stock ROM, does your sound work? It could be HW problem. But, have you been doing something unusual with your phone in thath "suddenly" time?
No on stock too it doesn't,there was one occasion though on stock to everything came back to life now again no audio(moved to Stock so I can take it too Service Centre)
If you try to take it to Repair-centre, you have nothing to lose. Thats worth of trying.
Thanks will do this and report what exactly is the problem,though audio is working again strangely,now I am sure it is h/w related
Update
Just went to Service Centre,they changed whole speaker set,but again no audio.
So finally he just said motherboard gone bad and will have to be replaced and said will take 2-3 days.
Does anyone think it really was the motherboard as everything else worked fine and audio came and went?
Also what can actually be reason for this(some water entered through speaker grill(it never did as per me but maybe some sweat or in rain a drop possiblity) or due to overclocking speaker went bad or due to extremely loud audio in mik's CM7 during call)
I will like to take advice from someone who might have experienced this or know something on hardware, so I don't repeat the same act.
I would now be damn scared to try custom ROM,but really the stock feels lousy in front of CM's,so please advice.
Phone Repaired
Well service centre replaced motherboard and sound is back permanently.
Though they didn't know what the problem was,anyone can guess real reason for that.
Now I am damn scared to try CM 7.1 again as it had loud volume could that have been the cause?
our phone has background hissing always present y

Serious microfone problem

Hi all
Am I the only one experiencing microfone problems on my new galaxy S3?? Im on my third I9300, because of this issue...
People complaining about that the mic vol goes up and down...
I'm also facing similar issues. I'm going to get mine replaced also.
First of all guys make sure 100% it's not the mic. Record some song and see if you still have the problem. I was facing similar issues with the mic going up and down durring calls.
In my case it was the simcard. Don't ask me why, because the same simcard was working fine in another phone, but after getting a replacement everybody said that they can hear me a whole lot better.

I am going through the very same issues.
I had a mic problem with my first S3 during phone calls. It was really annoying me because I couldn't do anything about it everyone was saying they couldn't hear me etc.
The sim I am using is an British UK O2 micro simcard that I used in a iphone 4, cheap samsung, and samsung S2 previously with no problems at all.
I then returned the phone to the T-mobile shop retailers, they said it was rare and not a common fault.
My new one is doing the exact same thing, I didn't update it nor is there a new update.
Can someone please help. Thank you.
I am getting the same issue but not everytime. I am sure that it is not the fault in mic that is causing this problem, as i recorded my voice (using both mics, the one at the top and at the bottom) and it was crytal clear.
turn off Noise Cancelling... fixed my problems
same problem
Had the same issue ,also with the s 2 , but the trick then (witch also worked now ) was to turn off the noise cancellation .
During a call just take the phone away from your ear and under the callers picture there u will find the option to do so
I have literally just started having the same issue today.
Am on FoxHound Rom 1.4 with Siyah Kernel. Had no problems, even made calls last night, perfect.
Then I tried switching Fast Dormancy on, flashed stock kernel and this morning I find when I made calls to Orange customer services, they were saying they couldn't hear me.
Tried testing it myself, and no matter who I call no-one can hear me.
I've tried:
re-flashing rom, kernel
Tried latest stock roms such as I9300XXBLG8_I9300OXABLG8_I9300XXLG8_HOME.tar.md5, none have made a difference. Even Roms I had backed up in clockworkmod that were working perfectly, like CM10 preview and CM9 have stopped working.
I've tried disabling Noise reduction, which has had no effect. Tried factory reset, flashing modems, kernels, roms, stock roms, nothing has made a difference. I can record video, google talk, anything else fine, just not get anything from the mic when making phone calls.
Tried putting a friends 3 SIM in, and the same thing, so it's definitely not network related either. I definately hope it isn't a hardware fault, as I bought mine on ebay and it isn't insured. Was kinda hoping for more than 2 mores usage out of a phone :crying:

[CM9 RC2] Mic not working whilst on speakerphone

Hi XDAers,
I believe since rooting (it might have occurred some time after) my Samsung Galaxy SII GT9100, I am not able to use my speakerphone as the other party to the call can't hear me. This problem is the same whether I use the regular phone, Skype, Viber or any other communication program. I have no problems with the mic when the phone is not on speakerphone, and I can use any recording application successfully.
I originally rooted my phone, flashed LighteningROM, went back to my service providers ROM (though rooted), and just today switched to CM9. I'm not sure exactly when the problem started occurring, but it was AFTER flashing to LighteningROM and before flashing to CM9. Is there any way to debug the error? Could it be due to flashing a bad radio or the like?
Any help would be greatly appreciated.
Speakerphone uses the top mic, not the bottom. Is the top mic clear and uncovered that you can see? If so, it may either be a hardware issue with the upper mic, or the rubber housing on the upper mic in the internals of the phone may not be seated properly, and is blocking sound to it.

The top mic seems to be uncovered. I believe I once read that Sound Recorder and applications alike use the top mic as well? If this is the case, why is the mic working in these applications?

You got me. Have you tried flashing back to stock and seeing if the issue persists?

Wasn't my intention to "get you" - hope you didn't take it the wrong way! I've just flashed back to stock ROM, but the problem persists. It appears people CAN hear me, however I am so low, they say it's worse than if I whisper with speakerphone off. Looks like it has to go back?

When I said "you got me", it's another way of saying "I don't know". I took no offense.
And yup, if you don't wanna mess with opening up the phone yourself, and you still have warranty, I'd flash back to stock, reset the flash counter, and send it in.

Did you ever get this working with your S2? I'm having the exact same problem. I flashed the stock 4.1.2 Jellybean via Odin and my stats are as follows:
Kernel: 3.0.31-Siyah-s2-v6.0b5+
ROM: I9100XWLSW
ROM Codename: REL
Radio Version: I9100XXMS2
Should I try flashing a different stock ROM? Does each one bring a different radio that may make a difference? Thanks.

Have you tried another ROM, restore backup etc. In short, what measures have you taken on your own to troubleshoot this problem.
- yes, the phone uses another means/ Mic when you are using loud speaker

Unfortunatly i was out of the country when it happened so i was never able to claim warranty on the phone or anything so i've had to live with it.
I have tried everything i can think of to try and fix it. Different ROMS, diferent kernals, different modems. nothing has fixed it.
One thing to note, is that when i have headphones in, the mic is fine. Would the be some trickery i could pull to make the phone always use the loudspeaker microphone, even when in handset mode.
current rom is paranoid android 1.99 w/ dorimanx kernal.
i think that lower mic is used when speaker is off , but in speaker phone it uses the the upper mic.

Sorry about that.
Your own case looks like a definite hardware issue. Too bad you are out of country but if you can still visit any Samsung service center, you might be lucky. Those guys are always very nice and helpful to customers in my country even if you are out of warranty.

I've not flashed a newer ROM to see if is that yet as its my wife's phone and I've not had time to back it up before I flash.
I have the same phone and not had this problem
I've also posted in the neat ROM thread and no one has had the same issue
So if there is two mics do you think it could be broken

Since its your woman's phone and you can't probably flash a new ROM at this moment, fine.
I'll say, let's assume it's as hardware issue.
I'll advise flash back your stock original or officially update firmware, And just send it to service center for repairs like normal warranty claim.
Good luck

Redmi note 2 Microphone bug

Hello. I bought this phone some days ago.. But when i make calls is very frequently that i can't ear anything and the person on the other side can't ear me. Im on last stable from Xiaomi.eu. Any ideas?
Defective microphone. You should apply for a refund. I also had this problem before with another phone, the seller give me full refund when I sent it back.
In my case it was working with recorder but phone calls or Google voice recognition weren't working.

Hey, I'm bringin this topic back to life. I'm also experiencing issues with phone call feature - people on the other side say they can't hear me well and that I sound like I'm standing far away from the phone. Can anyone tell me for sure wether this is a software or hardware issue?

Sometimes I have microphone issues too into calls , but only when I use speaker... Doesn't matter what ROM I use. I guess that's just the cheap quality parts into our device.. ( like soft keys stop working after 1 year )

This is funny! I had exactly same problem.
I was on global beta when it happened. Then I switched to global stable miui and the problem was GONE. Now I'm on Angel and Demons v9 and so far no such problems.
I'm using latest global stable. :/ 8.1.2.0.
