Improve Screen Performance on the Galaxy Nexus

While display technology is still evolving at an impressive speed, XDA member mumchristmas decided not to wait for the next technology to come available on a new phone. Instead, he investigated the current screen performance of the Samsung Galaxy Nexus using the Voodoo Screen Test application, a x-rite i1 Display 2 Color meter, and HCFR software. The results weren’t so good, as mumchristmas points out:

Average Gamma value is about 1.9, far from the ISO stand 2.2. So the color is just too bright (I’m 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.

Although he wasn’t able to fix the gamma value, he did manage to fix the color balance and color temperature, using a custom kernel with ColorControl function and adding a new file to the Android structure. The result? Objective tests report a much better color balance, but you’ll have to check it out for yourself to notice any improvements. Continue on to the thread to find all the details.
