Hi, I doubt within the next year, u can see a foldable with screen as durable and non-fragile as a normal rigid phone. So this will be a trade off for foldables.

Erm, what do you mean by "NOrmal USABLE SCREEN"? 
What's your issue exactly and is the problem with the cover, main (folding) screen or both?
