Nope, and I don't intend to anytime in the near future either. Mainly because I see it as just a gimmick with very little practical application. That and you're not going to convince me that you can make glass that will not break after being folded. No thank you. Phone screens are already expensive enough to replace.
Maybe impractical for you, highly practical in my life. Folding smaller makes it easier comfortably carry in accessible pockets, and the center of gravity is more stable so I've had no issues of it falling out of my jacket pockets which uses to happen to me quite a lot!!
Had fold 3 for 3 years. The UTG is not broken. And with it being folded closed when not in use i would be more concerned about the outer gorrilla glass breaking that the flexible inner screen....
Today I learned... My mistake. I was basing solely on the experiences I have had playing with the phones of 2 people I know that have them (one is the fold, one is the flip), the screens did not feel like glass screens to me, felt more like some type of plastic touch screens.
