The blacks are definitely not as deep as the AMOLED, but it is black enough, if that makes sense. It's not like the LCDs of old that made the screen almost look grey.
I think the screen is more vivid than the Note 5 I have compared it with. I'm very impressed with the colors!
I have been averaging 17 hours off the charger with around 5-6 hours of screen on time...it's the best battery life of any phone I have owned.
The speakers are ok. Not as good as previous models, but the headphones... amazing. I have heard sounds in songs that I have never heard before.
I haven't had a stutter or slow down or dropped frames at all. All of the animations are smooth as can be.
So far, it's taking great pictures on both cameras.
Very comfortable. The design of the back makes it feel great.
It is about as thick as a Note 5. And yes, it is very pleasing."
