Physical finger print scanner

[AnilSamFan]

The physical finger print scanner (either side or rear or front) should also be enabled to scroll up or down the screens. This feature is not there currently in Samsung phones. In some phones one can use it to pull notification bar down or up but it can't be used to scroll up or down any screen. If it is enabled it will be a great value addition

It had been there on earlier smartphones.
However still on newer ones also, you can set swipe down to view notification panel feature.

No. In general improvement needed in Galaxy devices.
