Hi!
I have a Samsung S8 G950W snapdragon running Android 8.0.0 latest build BRF5.

The problem is whenever I do some intense task like as playing PUBG or some power-hungry game the phone gets warm and then it crashes. Crashes means it just goes black (Straight turn off no Samsung Logo that we usually get when turning off phone manuallly).
So, when I turn it off right after I keeps crashing. The only solution is to wait for 5-10 minutes then start phone, let it stay locked for 2-3 minutes then unlock and use with low brightness along data or WiFi off. Then after use of 10-15 minutes I can use it normally with data or wifi on.

I'm getting this issue after Oreo update, never had anything like that before on Nougat.

My question is
Is anyone having or facing the same issue or is that me? Was someone able to solve this problem and find real reason behind this? Can it be an hardware issue or software glitch?

What I tried:
I have already tried several things before asking here,
1: I uninstalled many apps which I thought could be real reason for that.
2: I soft reset phone
3: I tried factory reset too (removing everything from internal storage)
4: Also tried formatting sdcard
I am running this phone without any modification. It is stock android.

If anyone has any solution kindly tell me!
