Hi. Ever since i bought my redmi 3 pro i have a microphone problem. It's not ROM related as i had it on global rom and on every xiaomi eu release up to 6.12.1.

When i call someone or get a call after a few seconds nobody can here me. Searching the web it seems to be caused by a bug in noise canceling. I couldn't find a software fix that works yet and the only workaround is to put a finger on the top microphone (next to the IR blaster).
Does anyone have a solution for this issue?
greetz and thank you.
 
Hey,
I have exactly the same issue. I thought it was due to hardware, but since you got the same problem it will be software probably.
Anyone got the solution? I can't find any for the Redmi 3 on the internet....
 
Hi everyone,
Try to add this parameters into end of the build.prop:

ro.qc.sdk.audio.ssr=false
ro.qc.sdk.audio.fluencetype=fluence
persist.audio.fluence.mode=endfire
persist.audio.handset.mic=digital
persist.audio.voice.clarity=ON
persist.audio.handset_rx_type=DEFAULT
persist.audio.fluence.voicecall=true
persist.audio.fluence.voicerec=false
persist.audio.fluence.speaker=false
persist.audio.fluence.audiorec=false
persist.audio.fluence.spk.mono=true

If you will still have a negative result after that, then try to disable the noise canceller and dual mic configuration:

ro.qc.sdk.audio.ssr=false
ro.qc.sdk.audio.fluencetype=none
persist.audio.fluence.mode=false
persist.audio.handset.mic=analog
#
persist.audio.voice.clarity=ON
persist.audio.handset_rx_type=DEFAULT
persist.audio.fluence.voicecall=false
persist.audio.fluence.voicerec=false
persist.audio.fluence.speaker=false
persist.audio.fluence.audiorec=false
persist.audio.fluence.spk.mono=false
 
Hi guys,
I come back to you again with 100% working solution regarding this issue. In additional to this, it resolved my issue with not working microphone on my wired headset Panasonic RP-HJX6M.
Just find and comment out the next rows in the build.prop:

#persist.audio.fluence.voicecall=true
#persist.audio.fluence.voicerec=true
#persist.audio.fluence.speaker=true
#persist.audio.fluence.audiorec=false
#persist.audio.fluence.spk.mono=true

Add the next rows at the end of the build.prop:

persist.audio.fluence.mode=endfire
persist.audio.handset.mic=digital
persist.audio.voicecall.mic=0
persist.audio.voice.clarity=none
persist.audio.aanc.enable=false
persist.audio.handset_rx_type=DEFAULT
persist.audio.nsenabled=ON
persist.speaker.prot.enable=false
persist.audio.spkcall_2mic=OFF

I have tested it on global developer ROM MIUI8 6.11.3. Besides that, the voice call has become much clearer than ever before.

this is not solve my problem...
 
for me with the fix it works for about 1 minute but if a call takes longer the sound drops again so the others cant hear me as before.
 
I got the same problem with different ROMS, I have tried factory reset and flashing but the same problem continues.

Tried to find and comment the rows in the "build.prop" but I couldn't because my cellphone isn't rooted...

does anyone know if there are any other solutions?

Thanks.

For me the only working solution is to cover the top microphone with a finger as i wrote in the entry post.
i wonder if its possible to just disable the noise canceling mic through the build prop.
