It's sounds like you've accidentally turned on one of the accessibility services for use with a switch.
First of all try booting in safe mode.
Turn off the Phone
Press and Hold the Power Button
When the Samsung Logo appears, Press and Hold Volume Down.
Release Power key
When phone has fully booted Release Volume Down.
To get out of Safe Mode, press and hold the Power Key until the phone restarts.
