It seems as if the project of bendable phones
isn’t buried at all. Lenovo shows a prototype of
a bendable phone in a short video. However it
looks kinda odd and it has a strange aspect ratio.

The screen is even longer suggesting a 24:9 ratio (something in that range). And it’s also quite clunky which means that it won’t easily snug into your pocket.

Also it’s doubtful if you can bend the phone a full 180° or more to halve it’s height while doubling it’s thickness.

But as it’s said, it’s a prototype and what we can see is that there is indeed capacity for something we dream of for about 10 years: Foldable full screen phones!
