My S8+ died?

OP: Sounds like a possible SOC problem. Most likely will only get worse. Exchange ASAP and avoid any further hastle.

Correct. I can sympathize though op. I went through the same feelings. Running games without issues, doing all sorts of things without issues. Only to be struck by that sudden hard freeze, just by opening my screen. Or being saluted in the morning by my pincode, due to an unsuspected reboot.
I managed to clock almost 100 hours without a freeze. So I decided that was good enough. Yeah sure, next freeze was within 24 hours etc etc.
But good luck with whatever you decide to do.
