DeFluence App -[Root] Potential Echo Fix

[stvn1337]

[ALPHA APP (V 1.10) ]
Disclaimer: This app only modifies the build.prop, so it should be harmless.
However, I am not responsible if your phone explodes, melts, dies, changes color, disappears, or any other humorous example.


On many roms, users experience a call echo problem. This is where the person on the other end of the line states that your phone is echoing.

Fluency- or noise filtering - could be the cause of you'r echo.
Another cause could be the Call Frequency/Band.


What this app does, is essentially try to optimize the build.prop settings with the Fluency/Noise Suppressing/ AANC all disabled and the AMR Wideband Codec enabled when you click the Disable button.


This app was created for my own personal use, and I am sharing it with you free of charge, but feel free to donate to me if this app helps you.

This includes various tweaks found all over XDA. If you are an original poster which discovered any of these tweaks, feel free to PM me to be recognized in this post.
Soon, I will attempt to find all original contributors of the tweaks used and modify this OP accordingly.

Tweaks Include:
___________________________________________________
Fluence mode and type
Fluence Voicecall (on/off)
Voice Clarity (on/off)
AANC (on/off)
Handset RX Type
Speaker Protection (on/off)
In Call Mic2
Handset Mic
Audio Noise Suppressor (on/off)
Audio SSR
AMR Wideband Codec (on/off)
Fluence on calls (on/off)
____________________________________________________

This app may or may not fix the echo problem for you, you will just need to try it and see.



Also open to requests / tips.

Хiaomi Redmi 4 pro, LOS Unofficial 13, Xtreme Music mod caused an echo in calls. This app fixed issue!

Hey @stvn1337, I am using JDCTeam Nougat ROM for OnePlus X and some of my callers are complaining about hearing their own echo on the phone. The same applies when using the speaker phone on Skype calls. This doesn't really happen all the time, so it's random (yet frequent).

Note that I've tried changing some of the settings in /system/etc/mixer_paths.xml but none of that seems to be fully addressing the issue...
Can you please let me know which parameters does your app change in build.prop so I can maybe try to do these changes manually on my OnePlus X?

Thanks in advance.

This app will be safe to use on any nougat+ ROM on any device as it only modifies build prop values. Have you tried the app to see if it works for you?

Not yet, but I wanted to know the exact values it changes in build.prop.

Thanks again..

 

[stvn1337]

I would try these setting in the build prop for the oneplus X device specifically:

/system/build.prop. Change
ro.qc.sdk.audio.fluencetype=none
persist.audio.fluence.voicerec true
persist.audio.fluence.voicecall false
persist.audio.fluence.speaker true
persist.audio.handset.mic=analog
persist.audio.voice.clarity=none

I have try this app but no luck, echo remain. Have you found a solution ?

I'm afraid not. The only possible workaround for now to avoid this annoying echo for my callers is to use a bluetooth or wired headset.

Speakers don't work anymore.

I used this and now while on calls, if I put my phone on speaker, I cannot hear anything. It just makes a distorting sound when the person on the call speaks.
Kindly help in fixing this. @stvn1337

The build prop settings that have been modified will need to be reversed. If the Defleunce app toggle isn;t helping then try deleting these lines from build.prop using a root build prop editor:

/system/build.prop.

persist.audio.fluence.voicerec
persist.audio.fluence.voicecall
persist.audio.fluence.speaker
persist.audio.handset.mic
persist.audio.voice.clarity

The file only had the first 3 lines. Deleted those.
Phone's back to how it was before.
Thanks a lot! ?

Hi,
My OnePlus X has always been having this echo pb. I would say 1 call out of 4 was problematic.
Now (since 10 jours approx.), with this apk, not a single complain about echo !
So a big thank you to the dev !
