Hard Reset - Warranty Void

[Oraki]

Heloo Sony,

Does hard reset voids warranty?

I'm having problem with calling functions.
Noise, echo and can't be heard by other party.

I Just bought it last week.
Model: Xperia Z3 Dual
Android Version: 4.4.4
Build: 23.0.F.1.82

There's another way, you will have to access either

myxperia or android device manager

You can reset your phone

Where to find that myxperia? uliwooly

Go to Settings > Security > MyXperia

Just keep in mind that you will need to have GPS, data / WiFi and the phone has to be on for it to work.
