I'm bummed it moving to 10.2 messed up my all black look as well.
I use both android and iOS and this one little detail really irks me because I don't like the frosted look on the bottom bar especially on my jet black iPhone 7 Plus. I will not be updating to 10.2 solely because of this one reason. Is there something I'd be missing from 10.2? I would love to find out if there's something much better in this updated version.
