Display testing and evaluations master Raymond Soneira from DisplayMate posted a comprehensive review of the Super AMOLED displays used in Samsung's latest Galaxy S7 and S7 edge phones. Raymond says that Samsung continues to improve its OLED displays, and its new Super AMOLED displays are the best ones ever tested on a mobile device, surpassing the Super AMOLED used in the Note 5.
The GS7 display (5.1", 2560x1440, 577 PPI) is actually quite similar to the display used in the Galaxy S6, but with some significant improvements - the maximum brightness is 24% higher, and the contrast and contrast under high ambient light has also been significantly improved.
The Galaxy S7 also introduces two important display enhancements. First us is a new personalized automatic brightness control that learns and remembers the display brightness settings that you set for various ambient light levels. The second improvement is the new Always-On Display mode that draws very little power and is quite useful. Finally, it turned out that this is one of the few displays that can be viewed with polarized sunglasses in both the portrait and landscape orientations.
This is no surprise at this stage, but the performance of the flexible OLED display used in the GS7 edge is pretty much similar to the glass-based OLED of the GS7. Of course the GS7 offers a large display (5.5" vs 5.1") with the same resolution (lower PPI).
