I wasn't sure what to expect from the iPhone 6 LCD 720P-sh screen, especially compared to my S5.
Prognosis is the iPhone 6 screen is pretty damn good.
The contrast is probably the best I've seen on LCD display, color saturation is just right, and display leans toward the cool side, which I prefer. Black levels are not in AMOLED class (nothing is), but black is pretty close to what it is intended to be.
Fuzzy? There is nothing fuzzy about it, and brightness levels smash my S5, even with auto-adjust reserve boost in sunlight. It isn't even close.
I'm also impressed with the display on the 6. I had a G2 then an M8 so I wasn't sure how the display on the 6 would compare, but it looks pretty good to my eyes.
