While testing some changes in the color science math of my calibration and measurement program, I took a look at my Galaxy S4 I9500 set to Movie Mode, at 100% brightness

This is is the mode described as color-accurate here: http://www.displaymate.com/Galaxy_S4_ShootOut_1.htm

Quoting:
The Galaxy S4 Movie Mode provides very nice, pleasing, and accurate colors and picture quality
Movie Mode, Very Good Calibration
Very Good Images, Photos and Videos have very good color and accurate contrast

Based on those high precision measurements, I beg to differ. My rating would be poor or very poor.
Color manipulations are so wrongly done that some secondaries (cyan and yellow) are not even in line with primaries!
Well, this is an example of what happens when using not enough data to cherry-pick evidence that suit your established conclusion.

That's the reason why I'm committed to provide display analysis software and training to any reviewer interested.
The current source , considered as reference is not as good as it should, also possibly biased based on the fact its conclusions doesn't even match the data published.

Anyway. Yay, the new code works great ­čÖé

  1. +rajan nakarmi I remember seeing some pretty strong dynamic contrast on the One X, which couldn't be disabled.
    That disqualifies it for any kind of color accuracy.
    The best mobile display calibration is yet to come, and excellent one from factory will require some changes in the industry as well.
    However yeah the One X display lens almost made the image float on top of the device.
