yesterday, i seen someone with the one of the officially avalible foldable phone, huawei mate Xs, so far haven't seen the samsang fold or motorola razr, mate Xs, unfolds to 1:1 square tablet in my opinion, kinda useless in tablet mode, netflix and youtube better in 16:9, but doable in 18:9, seems more niche than 21:9 super long ratio, the crease was notable from 50cm away, some people with deep pockets especially for a product with only 2.5 -3 years life span.
i believe this unique phone cost around HK$15999
