We know that Samsung is working on the Galaxy Note8. This was confirmed earlier this year by DJ Koh, Samsung's Mobile Chief. The Note 8 will likely debut this fall, but the first leaks have already been revealed.
According to the latest report from China, the Galaxy Note8 will have a huge 6.3-inch display, most likely with the same 18:5:9 aspect ratio as the Galaxy S8.
The same source claims that the Note8 should sport a dual rear camera setup. Unfortunately, no other info is available at the moment.
What is confirmed is that the Galaxy Note8 is coming this year and given how amazing Note7 was which was followed by the fiasco with the faulty batteries, I am pretty sure that Samsung will deliver a marvelous device.
In case you miss Samsung's Note series, the refurbished Galaxy Note7 recently showed up on a Chinese retailer's web site. The phone is identical to the original Note7 but with a new battery.
