Each person calling me is complaining about they can hears thereselfs, that loud that it's almost not possible to proceed the call reasonably...
Might be a software bug, when calls are done via whatsapp i.e. there's nobody complaining.
With this bug, the primary feature of a the mobile - doing phone calls - is lost.
That's not satisfying, particularly not at the price of an xperia xz 😞
