The crease on my Oneplus Open held up shockingly well after a year. Shane Craig and Greggles have both put out videos comparing those phones with the Find N5 and you can see what I mean. It’s barely any different from launch.

Oppo is comfortably ahead of the pack on the crease (for the last few years), but some of the other Chinese manufacturers are starting to catch up now and it’s getting close. Google and Samsung are lagging there, but that’s only a matter of time, and the slimness is obviously gonna happen organically as the new battery tech proliferates.
