We have hope, potentially. The Oppo Find N is a foldable yet it's MUCH smaller in all dimensions than the Samsung Galaxy Fold 3 and although it only sold in China, it was sold out in less than 12hrs there! Something both folds from Samsung of every generation could not accomplish. Then again that may just be patronage amongst citizens and native company vs a Korean company.
I still don't believe/trust folding screens is the way to go, too many moving parts too many points of ingress for dust, water and other particles to affect folding mechanism and build quality lasting over a few short years. I think rollable screens is best - if done right.
iPhone SE 4 = a 13 mini with 1 camera, no MagSafe, no FaceID but TouchID underscreen (if cheaper in 2yrs) or thicker power/sleep button.
