There is at least a decent advantage in the flip phones of having the screen protected when the phone isn’t in use. I could see them potentially becoming more popular over time if they are improved upon and become cheaper, if only for that reason.
In my opinion modern screens are scratch resistant enough to put in the pocket without many problems and if you need more resistance you can get a screen protecting foil or a case.
If my non foldable phone would scratch too much in my pockets I wouldn’t really think about replacing it with a device that is twice as expensive and has an additional hinge that could fail.
