Rumor: The most important feature on the Galaxy Note 8 is its dual rear cameras
While the Galaxy S8 and S8+ do not have dual rear cameras, it is highly likely to appear on the Galaxy Note 8.
KGI Securities analyst Ming-Chi Kuo, who is well-known for his accurate predictions on Apple's products, shares in his latest investor notes that the Galaxy Note 8 will be Samsung's first dual-camera smartphone. Calling it "the most important upgrade" in the Galaxy Note 8, Kuo believes the dual rear cameras consist of a 12MP wide-angle lens and a 13MP telephoto lens with 3x optical zoom. Both sensors will have optical image stabilization and six-elements.
In comparison, the Apple iPhone 7 Plus has a pair of 12MP cameras at the rear; a wide-angle lens and a telephoto lens with 2x optical zoom. Only the primary wide angle lens has optical image stabilization.
Kuo believes the dual rear cameras of the Galaxy Note 8 will be "much better than that of the iPhone 7 Plus, and likely match that of the OLED iPhone". Samsung was previously rumored to be working on a dual camera module for the Galaxy S8, but the project was canceled as the company felt that there was "no real value for it yet".
