I use my phones on the desk, table, and so on and the back sensor is an extra step for me, doesn't matter where it is or how well it works. Neither is facial or iris a work around because you have to pick up the phone. I've read many comment that after a time you become accustomed to rear scanners, might even like it better. Didn't happen with me, I've gone through a couple and I like them less and less the more I used them. While there is no perfect placement for every situation there is a reason why Apple and Samsung are trying to get the scanner under the screen, it's the placement that has the most strengths and fewest weaknesses. I'm a Note man anyways and as reports seem to indicate that we have hope Samsung will get the scanner they failed to get under this screen under that one it's a no brainer for me. My current phone is only a few months old and I picked up an LG watch sport the other day to get my toy need in check for a while. Assuming the international Note 8 can be rooted it will be my next phone.
