Poor call quality

[Peircy]

Is anyone else getting poor call quality on the compact? Is there any settings to tweak that will improve it?

The sound seems to be mumbled and echos during calls.

Disable microphone noise suppression.

Thanks for the quick reply. I will try this out and see how I get on.

I have received my compact last week.

I have what can best be described as an echo  when listening to calls and the call recipients comment that the voice is clear but sounds as thogh Iam someway from the phone.  Ive disabled noise reduction and audio enhancement but its not good and I will return this item

My daughter and I have both recently purchased Z3 compact and are experiencing poor call quality.  we can be hear clearly but the calls fade in an out and are very scratchy.  we are on the optus network and had no problems with our previous iphones on the network.  

turning of background noise suppression has not worked.

Just got z3 a couple days ago and love it. However the call quality is bad. I can hear them and they can hear me but I also hear this cracking sound. The volume isn't all the way up so I don't know what could be causing it. Any help?

I also have a Xperiea Z3 Compact which I am experiencing similar call quality issues

The recipients state that the call appears to drop / mute or gets very scratchy

I have tried with Michrophone noise suppression on and off and it makes no difference 

Model is D5803

Android version 4.4.4

I have already sent one handset back to Vodafone UK under warranty for the same problem

Exactly same issue as Burleyg, same model and Android version.

Anyone have a fix yet?
