Nothing fancy. 1 photo comparison. My friend also agreed N9’s display is visible brighter than his SGS2.
Not the easiest test to show with a photo instead of you seeing “live” but this is the only way to show it.
Anyways, the conclusion here is that N9 does have a nice AMOLED with very high brightness. (good for day time / direct sunlight)
– Have disabled auto brightness and set it to maximum brightness. Ensured that it doesn’t auto-dim after the timed backlight period. (made sure default web browser was also set to max brightness)
– Have set brightness slider to maximum and also had to shine a torch at the light sensor for a brief moment to trigger the maximum brightness. (You cannot disable auto brightness on N9 currently and hence this maximum brightness is not really achievable indoors right now)
I also have the Nokia X7-00 which has one of the brightest AMOLED of all phones according to gsmarena test. Nokia N9’s display brightness is very similar to the X7. However, as you can sort of tell from the photo above, my N9 exhibits a slight pink tinge at maximum brightness. So this makes it look less much vibrant than the X7-00.Now if your N9 does not show such pink tinge at maximum brightness, let me know. (make sure you trigger that extra level of brightness by pointing something bright at the light sensor)
UPDATE: I have now one other person here in Oz with N9 64GB reporting to have the same pink tint as mine. So I guess this might be normal. However, this pink tinge is not really noticeable while in a bright environment. Only in the dark but you can’t even use that setting while in a dark / indoor environment anyways.
UPDATE2: The pink tint has now been explained by Konttori (Nokia dev) as being intentional. It is called over-saturation which actually makes the colors more visible during bright sunny outdoor situations. It was never really intended for indoor use and hence this maximum brightness is not even accessible manually via the brightness bar. So this isn’t actually an issue. Also, apparently the colors have been adjusted in PR1.1 to make it more consistent at all brightness levels except the maximum. N9 even at its second brightest setting (which is accessible manually via the brightness bar by setting to highest) keeps the color consistent and is still brighter than the maximum brightness of SGS2. So you can say that the over-saturation maximum brightness setting is just an extra bonus for bright outdoor use.
