Don't wait for the Galaxy Note 8 if all you want is a bigger screen. That's because all signs are pointing to Samsung using a 6.3-inch Quad-HD Infinity Display. And while yes, that's the biggest screen of any flagship Samsung smartphone, the Galaxy S8+ is 6.2-inches. And you can buy it right now.
That means the Note 8 will only be a hair bigger than the Galaxy S8+, which is the smallest difference in the history of the Note series. It is bigger though, and that's all that matters for some people.
A big reason a lot of people chose the Note is for the big screen, and not necessarily the S-Pen stylus. If that's you, just go ahead and get the Galaxy S8+ right now and enjoy all it has to offer. However, those dual cameras sure sound fun.
