Hi @K44L. How often does this happen and does it occur when using a particular app or feature? Is your software up to date? Check this in Settings > Software update > Download and install.
That's not good @K44L
It's going to be a case of trying to troubleshoot what's happening.
If the following does not work then I'd ask for a replacement.
A Samsung Experience Store or Samsung Service Centre can take a look.
I wish you all the best with this.
Daily Driver > Samsung Galaxy s²² Ultra 256Gb in Phantom Black.
The advice I offer is my own and does not represent Samsung’s position.
I'm here to help.
