When something like this is happening @nmax I suggest the following two troubleshooting guides.

• Https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to hook up to a Computer or insert your earphones to enter into recovery mode. 
• Https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ will help to highlight if an app or theme etc is potentially causing issues. 

As a very last resort consider backing up and perform a factory reset.

I wish you all the best.

I would also recommend running App Booster after clearing cache. It's part of Good Guardians which can be found in the Galaxy Store.

I had this real bad after January patch. I noticed that when "Adaptive Power Saving" kicked in, it changed the screen refresh rate, which caused the lag. I disabled "Adaptive Power Saving" and no more lag for me. At least that's what I think fixed it, try it?
