[Galaxy Note II Original Android Development] Slimer777:
People, let not attack anyone on anything and do something productive.

I believe every word that everyone said. I would never challenge anyone who sees pinkish white because it is possible.

From what I have read so far, there are basically three groups of people; 1. satisfied with this sample calibration and don't think they have a problem. 2. Not satisfied because they see pinkish white. 3. People who simply loves vivid oversaturated colors. Now lets see how we can help everyone out. 4. people adapted to the sample profile and it satisfies them.

Group 1 and 4 need no help so forget them.

Group 3 cannot be helped or they can help themselve so forget them also.

Group 2 is what I am interested in. Lets find out scientifically what is going on. I need feedbacks and I need details. I need to know how your screen response to parameter changes.

Are you guys talking about pinkish WHITE only? or the whole screen is pinkish?

If the pink is only on whites then your phone is truely something else. If the whole screen has a tint of red, that's easy to fix. I see a lot of you changing parameters blindly and the change simply contradict itself. I am not going to go into the color science part, just do the followings;

If you have a Pinkish screen, go to White Color Balance. Adjust Red in White gradually until you don't see the red tint. Remember, adjust, look at some white paper, adjust, and keep going just so your eyes don't get trained to the current level of red. DON'T adjust Green, I am not going to go into this yet, just don't do it.

Now, use the phone for a couple hours, I don't care what the white point has changed into, all I care is that the red tint has to be gone. You may now have a different tint of color, that's okay as it's not over yet. At this point, you should be thinking..."it's just not white enough...." now, adjust the Blue in White slider until you THINK you get a white that you like and at this point, you should have no color tints on white. At least to your own eyes.

Again, use your phone for a couple hours, games, internet or whatever. If you still think that it is 'washed out', by all means adjust 'Chroma Saturation Weight' by whatever clicks that serve you. DONE.

All that you need to report back is how many clicks of red and blue that you have adjusted and we can continue the experiment. Now the 'To Do' is over, lets get onto some 'Do not do'

1. Don't attack the developer. The only reason that I rooted the phone and got interested in Andrei's kernel is because the ability to calibrate both primaries and secondaries. I have never seen anything like it on a cell phone. For us videophile, this is an absolute breakthrough.

2. Don't try to compare to anything else out there as a reference. Two problems here; (i) Chances are you don't have a good reference because broadcast grade monitors ranging from a few thousand dollars to twenty grand a piece. (ii) You are using your eyes as medium.

3. Don't try to compare to any Apple devices as a reference. Someone earlier mentioned MacBook Pro and since I have one lying around I just went measure it. Since Steve Jobs wanted you to have a unified user experience, ALL Apple products has a higher colour temperature meaning their white has a blue tint to it. Why do they do it? because bluish whites looks cleaner whiter to the human eyes. MOST i-devices have a less than perfect colour gamut except iPhone 5 and iPad4 which are closer but still not perfect.

4. Don't try to use a colorimeter to calibrate you device and think that it is accurate.Even if the colorimeter is profiled against a spectro on the same display, the spectro will still be more accurate measuring the colour gamut. Why some pros still use colorimeter? They are faster and have better low light sensitivity and like the Klein K-10 they are $7000 a piece. If a $200 Spyder is just as good, why would anyone buys K-10?

5. Don't do anyone of the above.

6. End of Don'ts.:laugh:

Pinkish screen people, get on it!

Now there is a member with good sense.:good:

Someone asked earlier that what colour temperature is the pre-calibrated profile, it's 6500K.

This is what other members should try except try not to touch the colour temp control. It will be used later.

All that it boils down to now is a simple white point calibration, simple fix. Chill.:highfive:
