I also found the video quite interesting, similar to other comments, I’m fine with the current UI… it offers something different, you know you’re using Android but, it feels distinctly different yet, it’s not on the opposite end of the scale where it’s mimicking iOS like many Chinese brands do.
I do agree with the comments re; the control centre though. I’m a former Huawei user and was spoilt by a comprehensive control centre where you could action most things at a swipe/press.
The rest of the video was very much personal preferences. I do see NothingOS as one of the more consistent Android skins and, think that the dot matrix styling is applied in the right areas, at the right times.
Finally, don’t get me started on RGB lights… I know Carl has said this wouldn’t happen and I hope it doesn’t. Not once have I felt the need for or, wanted RGB and like you rightfully said, it cheapens the look and the brand.
