Once you've downloaded a software update and allowed it there isn't a way to downgrade i.e revert back to the previous software via the phone's native settings @visage3
You could consider a Custom Rom which you can find out more on the xdadevelopers.com website.

Using a Custom Rom can bring about an unstable phone or it may not work properly if the process glitches or the wrong Rom is used.
A person takes full responsibility if they perform this process and do so at their own informed decision. Samsung would levy a charge to put this right.
However before this I'd suggest the following after a software update appears to make the phone sluggish etc.
1, Clear your phone's System Cache Files by turning your phone Off and then from a set series of button presses go into the phone's System Files and clear the cache. No information is lost this way. You may need to insert your headphones or hook upto a computer with your data cable to get to this menu on the phone.
2. First please put the phone in Safe Mode which disables your downloaded app's but let's your stock app's keep working. If the issues stop then this highlights a downloaded app as the possible issue. Come out of Safe Mode and start deleting your most recent downloaded app's one at a time until it stops.
3, A final resort is to back up and factory reset after removing any relevant sd card.
I wish you all the best with this.
