I work for a company that repairs these. The Flip and Fold phones have been riddled with issues since day one.

They're literally plastic screens. Over time the crease on the screen where the hinge is will get so deep that Samsung's required "screen protector" will no longer adhere. If you close the phone and the hinge decides to break, you can never open it a full 180 again. If you accidentally open it all the way too fast, you will literally rip the screen off the frame. The weak point is hinge which could lead to a thick black line across, or upper or lower portions malfunctioning. One day you may open the phone and it's unresponsive to touch. Screens randomly fail all the time and either display static or nothing at all.

Samsung knows the failure rates and how they're problematic. Any physical damage on the phone will void your warranty. If it's the tiniest scratch, warranty void. Not kidding. I see Samsung deny them left and right. If you remove the pre-applied screen protector and replace it with your own, warranty void. They literally record how many times they've been dropped. If the count exceeds an acceptable value, warranty void.

In terms of outright failure across all phone brands and models, the flips and folds are #1. Behind that is the A series. But those are cheap so it's expected.

Please purchase insurance for it if you can. It will save you at minimum $400 on a screen repair.
