Got to play with one more and I have to say - I like it a lot. However, I'm still leaning toward keeping my Note 4.
- It is definitely larger and though it's "not much more" compared to the Note 4, when you reset your scale by comparing it in your hand to a normal 5" phone, you realize just how large the phone is.
- Display is definitely dimmer - not an issue in-store, but I do wonder how it'll affect outdoor visibility
- The extra real estate is really noticeable and I wish the Note 4 had a touch larger screen.
- The build is nice - everything is very tight. However, the "metal" frame feels and looks like plastic. It feels like a very well put together plastic phone, though not what I'd call premium. The asymmetric design doesn't bother me at all and I'd like to see Samsung try their hand at a buttonless design like LG and Motorola that minimizes bezels.
- The side buttons for volume are terribly placed - even just playing around with the phone, I accidentally hit them several times.
- Sound is massively better than the Note 4- no comparison
The biggest thing for me is reported battery life. I run everything on (bluetooth, wifi, data, high accuracy location, Google Now, constant syncing) and the Note 4 barely gets me through my full day. A phone that does noticeably less is too much of a negative to me. Equivalent or very slightly less would have been good enough. I have no desire to disable functionality to get good battery life.
The camera in low light conditions is also an area I don't want to go backwards as the Note 4 is the first Android phone I've had where low light is good enough. I don't want to go back to depending on my wife's iPhone in those conditions.
So a very interesting phone - I'd 100% get it if it had the display and camera quality along with the battery life of the Note 4.
