Z2 Echoing issue during video calls

[CLo]

When using video chat apps such as Google Hangouts with Z2, I experienced severe audio echoing throughout the call.
I understand the usual way to solve this issue is to use headset.
But this echo issue wasn't so bad with my previous devices (Z, Tablet Z)

Echoes on Z2 starts as soon as I speak and it doesn't end until I mute the microphone. It's also loud enough to make me unable to hear anything from the other end of the call.

Is this a software issue or a hardware defect? Is there any settings I can change or do I simply need to exchange my phone?

TIA.

I had similar issues with other Xperias and for the most part the issues were the app itself, or a poor data connection on the other side

So, here it is, my wife and I got two Sony z2 from Bell.
We have had them for three months.
However we have not had them for month and half as we have sent them in twice.
We just got them back and still have problems
Her phone heats up to the point wear you can hold it.
There is horrible echoing when using Sony install handouts (or any other video chat)
Her battery is not holding a charge as long as mine.
So.please Sony reply with good news on what we should do. If I send them in a third time
I.do.not want them back.
We moved from iPhone to you and we can not.video chat while I.am.at work.
Can you send us new phones and stop.this horrible service, that your current repair shop is providing.
Please help

My girlfriend and I are having all of the same problems... With no help from Bell or Sony. I will never buy another Sony product.
