My flip recently had an issue with the screen protector coming away from the screen and two dark circles appearing at the top right of the screen, I contacted samsung and they arrange a home repair within 3 days, it has now been repaired with a new screen and battery, it also looks like the frame has also been replace, shame this happened but credit to Samsung for a great and swift repair, phone is 8 months old
Did you pull if off? That won't be coverd under warranty. Those screen protectors on the fold and z are basically glued onto the display. If your screen protector suddenly came away from the display it means you pulled it off.
