XZ1 UI crashing/ stopped oreo

[KittieHearts]

I was just wondering if anyone else had this issue. i've had to do hard restarts on my phone as i will lose the screen sometimes. i keep getting the message that my Ui has stopped working. i'm slowly running out of ideas. has anyone else had this issue or is it just a bug in oreo that might be fixed?

I have been having this reboot problem since purchasing the xz1 about 1 month ago. This is a very disturbing problem as the whole basis of buying the Sony product was for the reliability. To be told that I can't refund either because I have used it makes me sad. £660 WASTED! Please help make this stupid phone work.

Update

Performed factory reset. The phone worked normally for a week. It's now gone back to freezing. Crashing having bad performance recognition. I have only installed my carrier app and one drive. 

Factory resets usually fix everything bug it hasn't. I've even taken the SD card out ax thought that could be the issue. Is there any other solutions.

actually you should be able to get a refund as the phone is have issues. you might have to send it to warranty. I'm almost at that point.
