Oh the thing I read mentioned the S8 directly. I'll see if I can find it.That was the issue with the older nonexistent Note 7. The S8 upped the security measures and im sure the Note 8 went even higher on it. So that’s not a problem with the current Samsung phones anymore.
To my knowledge, the only one’s who were able to do it were German Hackers thru a IR picture printed out by a lazer printer and using contact lenses. These hackers were also able to hack the IDTouch from the iPhone, so go figure.
