I'm not sure if this is an issue, or where it belongs, but I think I mistakenly wrote an app developer of a night-time alarm clock yesterday telling them that the "black" background on their alarm clock app was more a bluish glow—similar to a TFT display—which should not be the case on the Galaxy Nexus.
Then, I ran a screen test and discovered that a pure black background with NO soft key glow (I have made my soft keys 100% transparent) and no other elements on the screen, is actually bluish if you view it in a completely dark room
I don't recall the screen exhibiting this bluish property when I first got it, and I played around with the both color control settings and brightness, to no avail.
Is anyone else unable to achieve a "true black" on their Galaxy Nexus, running the latest milestone builds of Franco's Kernel and AOKP?
What could be the cause?
UPDATE: Found this post in another forum regarding the screen glow. Not sure if it could be fixed in the kernel, but I just never noticed it before yesterday.
