I had issues with my 950 xl when I bought it, It used to reboot at least twice a day. Then I opted release preview ring and my phone was good but recently it started again with the new update. So I did a full reset using WDRT and opted release preview again. U will get a configuration update after that and it solved my reboot problem. Thought this might be helpful for u guys. I am using single sim 950 XL international version
