So far feels much smoother and fingerprint feels better i didn't even had to re-register, tons of new features from the OneUI 2.0 i'm digging it. (for example we now have Dynamic lock screen, Dual Audio, Adapt Sound can be now activated for all media or just multimedia, or only for phone calls, you can rebind side buttons for different stuff, turn off fast charging and much more)
I only dont like the new FP unlock animation, hope it's possible to change it.
I dont really use camera much on my phone (but i noticed there is a Pro mode, not sure if it was here before), but i will try running some benchmark later, performance (smoothness) feels very goooood. Also if someone wants it's now possible to turn off fast charging.
