Callers hearing their echo in redmi note 7 pro

[Maxpayne_12]

I bought redmi note 7 pro on the very first sale from Flipkart on 13 march 2019
But unfortunately i had a problem in the handset..
The caller was hearing his own echo..on the receiver side during normal calls and..even on whatsapp or facebook messenger calls
I got the handset replaced ..
But unfortunately i am having the same problem even now..
I chatted with your customer support and even called them atleast 4 times..and everytime they told me to wait for an update..but i had received that update..(miui 10.2.7.0) but still the problem is not getting resolved..they told me to factory reset the device..but it was of no use..they told me to swap the sim cards .but no use..
And i think i am the only one facing this issue
What should i do ?

Replacement handset has same problem

Replaced handset, did factory reset, updated MMuI 10.2.10.0. Still problem persists.

Absolute peice of rubbish junk.

Is there a way I could ask for refund.

Learnt my lesson hardway.. Never trust Chinese crap... At least not the latest release to market.

I am having Redmi Note 7, I am having the same issue. After replacement of Device, the problem is still the same.
Done factory reset
Tried multiple Sim card
If I use the headphone issue get resolved but without headphone, you will get the echo.

Anyone here who got this issue resolved.

Remove silicone cover from the device. Hope issue will never persist.

 

[PKM1]

All of you fellas have a backcover installed.Remove the back cover and check

 

[MaxEmp]

This is killing me man. I really need my back cover.

 

[Shakti_Shadow]

Even I am facing the echo issue. Also sometimes screen became inactive during call and i am not able to see or do anything on screen.
Is there any solutions available. Please suggest.

 

[MaxEmp]

It's just a theory, but... the phone have two microphone, the second, in top it's for noise cancelling. These two microphones if not syncornized well, the echo appear. If without cover the sound it's clear, no echo, check if the silicone case have hole where the second mic.

I saw posts about the second noise canceling mic. Anyways, I thought it had to be the design of the case that had to carry sound from the earpiece to mic or mic to 2nd mic or whatever.

Note the original openings on the side of the case.

Therefore I carved out section in the case where you find the main microphone. (used a red hot nail to do that)

Echo is now gone.

Solved it Myself
If your phone is rooted download Build.prop editor (By J Rummy apps). Navigate to System>Build.prop through the app.

Check for the following codes in the file
#Audio
ro.qc.sdk.audio.ssr=false
ro.qc.sdk.audio.fluencetype=fluence
persist.audio.fluence.voicecall=true
persist.audio.fluence.voicerec=false
persist.audio.fluence.speaker=false

If the aforesaid lines are not there in that file, simply paste them there and your echo problem will be resolved.
