Xperia XZs Proximity Sensor Issue

[Taroonz]

Please help, proximity sensor doesn't work properly .. Screen blacks out on calling immediately... It comes back when i push upper left corner of the phone... Is there a way to re caliberate the proximity sensor?

It looks like a physical issue to me, so I'd recommend that you contact your Local support and get your phone inspected by a professional.
