It's just the location change. Whatever apps support the fps continue to work the same way irrespective of it's in the back or front.Awesome guys!!
Do all the apps work the same with the FPS?
How does Samsung Pay work now that the fps is on the back? Do you touch the sensor and then place the phone against the reader?
Should I be able to wake and unlock my S8+ by just placing my registered finger on the FPS?
That's not working for me.
