DisplayMate posted a review of the new flexible Super AMOLED display used in Samsung's latest phone, the Galaxy Note 8. This is a 6.3" Quad HD+ (2960x1440) flexible edge-type display and DisplayMate says it improves on Samsung's previous OLED display (the one used in the Galaxy S8) and it declares that this is the best mobile display ever tested.
DisplayMate says that the new OLED display has several improvements compared to the previous generation display, and Samsung also included several new display features and functions in the phone. The major improvement is that the Note 8 is 22% brighter compared to the GS8 - it reaches a peak brightness of 1,200 nits - the brightest mobile phone ever.
Other improvements in the new display include a full 100% DCI-P3 color gamut, a user adjustable white point with color balance slider for adaptive display screen modes, improved automatic brightness settings that use front and back light sensors and a new night-mode with a blue light filter.
