According Kate Beaumont, director of product, services, and commercial strategy at Samsung UK, this boiled down to protecting the display where an inwards fold would protect it better tthanan outwards one. “We considered a lot of options. There’s things like if you want to put a case on it, usability, durability, and we feel that having the screen on the inside is the best way to protect that screen.”
Beaumont adds, “We have the technology to do a fold that is very very tiny, as of course if you have the fold on the outside it doesn’t take quite the same amount of research and development to get that device to fold as it does something that is folding with a much lower angle degree on it.”
At this point in time ,it is unclear how durable either Samsung or Huawei’s foldable displays are in terms of how many folds they will allow before it breaks. There is also the question of functionality where we have yet to discover how useful foldable phones are, or how novel they might be.
