Ive been excited to see folding phone screens for a few years now, but I'm reminded of the horrible creases that form over time (at least in the Samsung models I've seen).
Are there any folding phones on the market now that don't have this issue? Any that are worth the price?
I have a Z Fold 4 and I like it a lot for the screen size. Like others have said, the crease isn't noticeable once you're used to it. It's not all great though. I had the first one replaced under warranty because it stopped working correctly when a cable in the hinge must have snapped. I would be concerned using this phone without a warranty.
I'm guessing like you said screen size is the defining difference here (thats a lot more screen to bend), along with camera quality being a bit better, and also they want to encourage the perception that the Z Fold is the more premium product.
