how do you replace the screen protector on the inside screen?
You cannot remove the screen protectors on ANY Samsung foldable phone, removing them destroys the screen. It’s not meant to be removed(even if it looks like it is). Don’t remove it if you want to save hundreds of dollars to get the screen replaced.Hope I helped :D
Just peel it off. On Fold 3 its not part of a display and after a year it will start removing itself anyway. Highly recommend having replacement at hand.
