Call HP support. Your problem could be the result of a defective sim/SD card tray. When I purchased my elite X3, I had a phone reboot in the middle of a call. I'd read before of this happening to someone and called HP tech support about it. The techs sent me a replacement sim/SD card tray. They stated the original had a design defect causing such problems mentioned. If I can remember, they'll ask for a number etched on the tray which is difficult to read with bare eyes. You'll need to have this information ready before you call. Use a magnifying glass or your phone's camera to take a close, clear picture of the tray where the number is located. Look closely and you'll see this number. HP tech support will ask you for this number to determine if you need a replacement tray. I received my tray within one day, didn't cost me anything extra, and I haven't had any more reboots during a call.
