Color me unimpressed. Big feeling of meh.
Sure the Note 7 is an upgrade over the Note 5, that's easy with the small battery and no SD card on the Note 5. But other than that, I'm not all that impressed with the Note 7. it ships with the old and soon to be outdated Android Marshmallow, with Android N officially releasing before the Note 7 hits retail stores, meaning you'll be waiting until Spring 2017 until the Note 7 gets N.
And it's still Touchwiz, yeah yeah I know, Touchwiz has been improved. But it's still a laggy slowdown after 6+ months of use. My Wife has the Note 5, and it's almost one year old, and it's pretty laggy now, whereas compared to when she first got it, was warp speed fast, smooth as butter, but over time it starts to get choppy, like those old Windows 95 PC's.
My Wife also had the Galaxy S6, same thing happened, at first was a super fast and smooth phone, but many months later, a different story.
Now my Nexus 6P, I've had a while now, it still feels snappy fast, and smooth as butter, no different than the first day I got it. And I will get Android N right away this month.
To me the only smartphones to buy, are the iPhone Plus version, or the premium Nexus phone.
