Network problem and not vibration not working in my Xperia XZ

[Camillus_Pancra]

I bought this phone in the month of March and within 15 days I got a problem that Network won't connect. Service center have fixed the issue by replacing the display and NFC device on the phone. Now vibrate mode is not working and the phone is getting heated even it is on idle mode. I think it is big time Sony has to  replace my phone. My last 5 phones were Sony Xperia, now problem on my 6th phone. I am very much unsatisfied with the device offered to me

Hi @Camillus_Pancras, I'm very sorry to hear this.

If the vibration doesn't work when you test it in Settings > About phone > Diagnostics > Tests I'm afraid it may be in need of repair. I recommend that you contact your Local support team directly for further assistance with this matter.
