All I know is that if last year Apple had offered a foldable iPhone with similar hardware to what Samsung is selling alongside the non-foldable iPhone 15 Pro I bought, I would not have changed my purchase decision.
I'm sure the people buying Android foldables now are doing so for legitimate reasons, but for my use case the trade-offs take away a lot more than they add, so the current technology as-implemented doesn't interest me.
It's possible that a "neo-flip-phone" that actually works like a flip phone--meaning you can snap it open and closed satisfyingly with one hand, rather than having to crank it open with both--and solved the crease issue, I might consider it, but given the wallet case I prefer and the difficulty in making a case to protect a foldable phone from someone who drops it regularly, I still probably wouldn't.
An aside, I say this every time the topic comes up, but I have a coming-up-on-two-decades-old dirt-cheap slider and flip phone sitting on my vintage-hardware display shelf, and it's genuinely impressive how pleasantly tactile opening and closing them feels. It's actually fun to do! You want to just snap the thing open and closed for the heck of it because it feels nice, and the durability is such you can do that without worrying about breaking or creasing it. Contrast with the gummy-feeling hinges of modern foldable, and it's genuinely sad how far backwards we've gone.
