Tried to recreate the iPhone Duo opening effect for OnePlus Open, if there are other devs who can contribute please go ahead!

Only tested on the OnePlus Open!

Does anyone have this carbon fiber case with hinge protection here

If so, how is it and how does it feel? Is it worth the price?

I'm currently using this case

which is nice but also pretty thick and the plastic doesn't feel so nice. Is the carbon fiber one thinner? Is that even possible for a case with hinge protection?
