The finger print scanner is a non issue trust me after a day of use you'll know where it's at . beside why not use the super fast iris scanner
Firstly the S8 phones have been a commercial success even with an awkwardly placed scanner.
If I had a new Samsung, I'd never use the fingerprint sensor. It would be iris scanner 100% of the time (not counting trusted places)
I don't even use the FPS I have now, so that doesn't really bother me I guess. I get how it could seem frustrating though.
I only use mine to log into apps. Like my bank, or credit card. Safe, secure, easyotherwise, i live with an 11 yr old, dot pattern all the way
shell lock herself out before guessing it
