Sooooo unfortunately I had to return my S8+. The FP scanner was the deal breaker. I need to lock my phone, I use it for work. So I am unlocking my phone countless times a day, and there is nothing as seamless as a good FP scanner. Also, there are a great many places around me that take mobile payment, so another use case in which the FP scanner just made things impossible. Iris scanning is fine when you're stationary at a desk, but on the go not so much. And I sure as hell ain't going back to tapping in a 4 digit pin constantly again. Horse left that barn a long time ago.
I've said this before, and I want to be clear: while the placement of the scanner isn't ideal, that wasn't the issue. The scanner itself is crap. There were times it kept rejecting my attempts where it got to the point I wanted to throw it against a wall. I don't think this can be highlighted enough because if Sammy simply "fixes" this on the Note 8 by moving the same crappy FP scanner to a better location, it won't matter.
