The Samsung Galaxy Nexus sports an HD Super AMOLED display that is currently blowing our minds, but it seems it is not perfect. XDA Developers member mumchristmas has taken it upon himself to investigate just how great this display was, and came up with some disappointing findings.
The user used an application called Voodoo Screen Test, and he found the following issues with Google’s flagship device:
Average Gamma value is about 1.9, far from the ISO stand 2.2. So the color is just too bright (Im not saying screen brightness).
The shadow part (0-40% gray level) of 3 color curve were almost out of trim. In another words, inaccurate color balance.
As the color unbalance. The color temperature is starting from lower than 5500K to 6500K, which the ISO stand is 6500K at any color level.
It was not possible to fix the gamma value issues, but the user’s custom kernel is able to improve the device’s color balance and temperature. The custom kernel comes with ColorControl function. After installing this, as well as a new Android structure file, the color balance is said to be substantially improved.
In order to get this kernel, you can simply head over to XDA Developers and check out mumchristmas’ thread. As always, be careful, this may void your warranty, and it is no one’s responsibility if something happens to your device.
With that said, check it out if you feel like getting a better display experience. And don’t forget to come back and let us know how it works.
