You cannot rollback the firmware via any settings in your phone once your phone has updated unless you use a custom rom but a person has to be very careful when trying this. Look at xdadevelopers website for more info.
Be aware if something goes wrong with using a Custom Rom you could end up with an unstable phone or in the extreme unusable.
A person decides to use a Custom Rom at their own informed decision.
Before looking at this though inwouod strongly advise to back up, remove any relevant Sd card and Factory Reset.
And or let a Samsung Experience Store / Samsung Service Centre have hands on with your phone.
