Sony experia xz2 shuts down unexpectedly

[Sofe1]

I've owned my phone for less than a month and noticed that when my phone is in operation, it automatically shuts down and reboots itself. This is rather annoying when I'm on the phone and it shuts itself off, ending my phone conversation. I need help to resolve this issue. 

Thank you 🙂

Yeah, I have a same problem with this random restart.

Never had this happen to me on any firmware version and I have had this phone since release day. 

I recommend you seek a replacement. 

Had your problem on my note 3 even after factory resetting it. To this day it still does that. Worst is when you're using it as GPS and it reboots
