So had it for a day or so now.
Still love how good it feels to hold - massive difference when holding the old S6 at the same time
battery life is SO much better than my old S6, and I've changed the screen resolution to the max
Camera seems good
Slowly getting used to the finger scanner location, but I've got retina unlock active as well which works well except when I have my glasses on! (doesn't seem to have any problem with my contact lenses despite the warning)
I disabled Bixyby and my Bixby button now does nothing - wish I could map this to something useful!
My screens don't have any red tint except on the edge which is expected due to the angle
