I am loving mine. Had the OnePlus Open before, and I am shocked at how much difference the thinness and larger screens make. It really does feel like a normal flagship slab phone.
By those standards, the speaker is sub-par (but does the job) and the Ultra-wide camera is noticeably weak. The main camera and telephoto camera aren’t going to win awards, but they aren’t the weakest you’d see in even a flagship bracket - they don’t feel cheap, but won’t blow anyone away.
That aside, it’s glorious. Thin, light, fast, powerful, amazing battery life, the smallest crease I’ve ever seen (and you really only see it at off-angles, not in normal use where the screen is facing you). I know the OS isn’t as versatile as on Samsung phones, or as seamless as Pixel phones for those who use all of Googles services, but it is a really smooth, attractive and well-optimised OS with a good range of functionality and I think boundless view/Open Canvas is the best multitasking UI around. I’m happy that I don’t have to use weird workarounds to have circle to search, too!
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.
