To be honest samsung has just added new features and kept the ones which were already present in one ui 3.1. But the new ones which i discovered till now are working superbly and haven't seen any bugs or issues such as battery drain either so if you are a S20 Fe user you can go ahead and install the update you don't have to worry and you definitely won't be disappointed.
Thanks for sharing valuable information. I am afraid to update as my mobile has lot of my work place Apps if any of it stops working after upgrading all my work in jeopardize and it's quite difficult to get them all setup again in this WFH sautuation.
