Voice echo on Sony Xperia Z5 Compact

[AC Question]

Hi. I have an issue where everyone I phone from my Z5 Compact complains of a voice echo.

I know this issue existed on previous Xperia phones but can't find any mention of it online in relation to the Z5.

Anyone have any solutions?

Hello!

I have the same issue with my new Sony Xperia Z5 Compact. The receiver of the call has a ~1s echo of their on voice for the first 5-10s of the call and then everything is clear.

Anyone have any tips? It has been like this since when I first got it a few weeks ago.
