Yep the oled was relatively poor compared to the best. Low peak brightness and inadequate sRGB calibration to add to your list.
Postituves were proper front facing stereo speakers, though some reported rattles and distortion.
And the usual fast updates, but with more bugs than we'd like.
Problems with fast charging and battery drains are just not acceptable at this level. If it weren't for the camera it wouldn't be note worthy at all. I'm hoping tgat all these problems are fixed in the 3, I can live with the notch if so.
