The note 7 was the brightest screen on any phone. Comparing the v20 to my s7 edge in the store, the edge was maybe a little brighter when they were both at max, but with both at 75% the s7e was clearly brighter. LG screens seem to only get really bright above 85% or so.
Viewing angles on the s7e also blow the v20 screen out of the water, but I expected that. All in all, I've accepted the fact that I'm downgrading in the screen dept to regain a replaceable battery, a bigger (flat) screen and an ir blaster. I'm surprised how much I've actually missed the ir blaster lol.
Not in recent tests. It only did around 500 nits where the lg did 700 and iPhone 700.
