Its already been established several times over that there are some screens that do not respond well to the calibration profile and some adjustments on the red in white must be done, just because your screen happens to perfectly work with the profile it does not mean its gonna work for everyone else. It would be more helpful to the thread if you post actual solutions.

Re: [Kernel][28/02][N7100 N7105 R950] Perseus

I use master sequence for a couple days and very satisfy with it. today after reading Slimmer777 about how to properly (micro) adjust the white balance. I end up with -4 for red in white and it just perfect.

For the gamma, I can read all the texts at about 20% brightness. but at minimum brightness i can see something in the dark but cannot read the word.

This is surely the best kernel and the best calibration. Thank you.

Hi,

I just want to personally thank AndreiLux and Slimer777 for this wonderful creation.

The battery life and screen is unbelievable. Thank you. :)
[Galaxy Note II Original Android Development] Slimer777:
Lets just all measure at 50% brightness which is Samsung's standard brightness. If you can make out the 5 lines at 50 you will have no problem from 40-100%. I don't think anybody would watch any video material in total darknesss with brightness at 30.....Then again, some may.:o

On my phone with 50% brightness, I can read very clearly 'perseus' but the other 4 are blurred and not clear.

So guys, at 50% brightness, in total darkness, what do you see?

---------- Post added at 01:18 AM ---------- Previous post was at 01:15 AM ----------

With 'master sequence' ticked, ticking SCR = disabling it.

Give it a try, default everything, tick 'master sequence', tick 'register hook' and leave everything else. What do you see?

---------- Post added at 01:21 AM ---------- Previous post was at 01:18 AM ----------

Well, you are correct.

It has been repeated numerous times, if someone thinks his screen is tinted with colors then go and read the DOs and DON'Ts.

---------- Post added at 01:28 AM ---------- Previous post was at 01:21 AM ----------

Another member able to adjust to his liking, great. There is no real 'right white' or 'wrong white' unless you want to get technical. For movies are different because the directors want you to see a specific tint or colour to his film and the reference standard is at 6500K colour temperature.

But for a phone, unless you want to watch a movie on it you can set it to whatever you desire.

Seems like so far I have the highest gamma. It's good to know what's out there.

Re: [Kernel][28/02][N7100 N7105 R950] Perseus

At 50% brightness in total darkness I can see "Perseus" clearly but not the 4 levels. At 100% they're all clear.
[Galaxy Note II Original Android Development] scote:
Re: [Kernel][28/02][N7100 N7105 R950] Perseus

on my 7105 Perseus was the clearest, the level one to three were readable and level 4 you could just make out something at 50% brightness

I have only master setting enabled in stweaks, everything else is at default now.

There is a setting in the stock display settings "auto adjust screen tone", I think it may have been slightly clearer with that setting off, but my eyes could have been getting used to the dark by then.

Re: [Kernel][28/02][N7100 N7105 R950] Perseus

50% I can vaguely make out the perseus. Had I not viewed it at 100, I would have thought the stuff above was random rendering artifacts. That said, they're barely noticeable at 50, and can't make them out at 100.

I tried to grep lcd from dmesg, if it would help but I think my uptime has been too long. If there are any hw specific things you'd like for comparison, just let me know.

So, since installing 33.3 I have a charging issue. My phone gets to 100%, but the led stays red and it continues to say charging.

If I install 33.1, it goes to Charged and I get the little status bar icon saying the phone is fully charged and the led goes green. Also tried the newest Saber Kernel and that works correctly also.

I flash 33.3 again, and its back to 100% and charging and red led.

I redownloaded the file again to make sure it was not a file issue, but same thing.

So.....amyone else having a charging issue with 33.3? Just seems it never triggers the fact the charge is complete.
[Galaxy Note II Original Android Development] themichael:
let it charge for 10-15 minutes at 100%, it will change over to green eventually. battery percent is never completly accurate as it is a very accurate educated guess by the software but still a guess.

Ok, let's re-word this so that even a 5-year old can understand it.

If you have a red-tint and you are posting your personal values which supposedly fix this (like -6 red in white), please also provide your display type.

If you think your display is fine (Good white), please also provide your display type.

If you don't have anything to say, then please don't provide your display type because it doesn't advance anybody on anything.

Edit: And this is after you have had the master profile going on for a while, so people's eyes get used to it.

Forgot to mention I'm on EA8061

When I first flashed 33.3 it was 4 am this morning and I thought my photos really looked great.

Come morning time, I have started to see more magenta tint and thought it will go away by after lunch when my eyes get used to it.

Lunch time at work, I see greenish tint with the magenta still there.

This evening when I used the phone in my room, I thought it looked washed out.

So I tried the Red to white, Blue to white, and the Chroma Saturation Weight setting that slimer mentioned earlier in the thread, but to no avail, I didn't like the results.

The magenta tint disappeares after -6 to -8, but the screen looked washed out and looked greenish.

(here it is because it can get difficult to find for people who haven't followed the thread - http://xdaforums.com/showpost.php?p=38592217&postcount=2940)

I think the problem lies when viewing the phone in different lighting conditions, just like when calibrating monitors, you get different results/readings because of ambient light.

Also bearing in mind that no 2 similar phones have similar quality screens, again just like monitors.

Also add to this the automatic brightness that kicks in, then it gives more problem (at least to my eyes)

Only solution I can think of, is if there is a feature in the phone with automatic gamma and ambient light correction, maybe the devs can achieve an excellent result.

Or another way is for slimer to give us presets (to toggle) at different phone brightness and and white balance. But maybe automatic will be better.

Another possible way is to not give us presets and just give simple controls for red green blue, gamma, and white balance/kelvin. So people can only blame themselves if their screen color is not good.

Many many thanks to your hard work Andrei and Slimer.......

Re: [Kernel][28/02][N7100 N7105 R950] Perseus

Using cool tool I see that with perseus at default settings 4 cores never go online at the same time. Most of the time there are 2 cores online. With stock kernel all four cores go online quite often.
[Galaxy Note II Original Android Development] MeetFace:
You doing things that would require that much power?
[Galaxy Note II Original Android Development] i900frenchaddict:
So I guess stock kernel put the 4 cores online too quickly even if it's not needed (and thus draining a little more battery).

I mean, perseus is great in term of performances when huge power is needed (for example: PS1, N64, Dreamcast, PSP emulators, etc.)

To be honnest, only a few apps really require the full power of the Note 2 ;)

Is it the same during a CPU stress test or a benchmark like AnTuTu? What is your i/o scheduler? (try using deadline)
[Galaxy Note II Original Android Development] Mindfield21:
Re: [Kernel][28/02][N7100 N7105 R950] Perseus

Is it that stock puts all cores online while not needed or maybe perseus isn't triggering all the cores when needed? I tried heavy apps and procedures and perseus kept using only 2 of the available cores...

The panel is the same model produced by Samsung, there aren't many OLED manufacturers out there. I don't think they multi-source it.

As for the MagnaChip controller, no idea. We didn't establish any pattern yet in how it's distributed. I just know that it's a minority of devices.

i know i had the red in white for my i9305 at 0 before, but comparing for ages in a dark room I found this to be the best. the i9300 seems to be the best config off the bat, the n7105 whites are quite different in the dark and it's hard to adjust the red in white to make it the same as the i930*
[Galaxy Note II Original Android Development] Slimer777:
Exactly. The i9300 colour calibration has gamma correction while the N7100 does not. I also notice for the i9300 that after gamma is corrected, you get less banding because the gamma curve is smoother.

Seems like the two drivers doesn't make a lot of difference, I guess that is because Samsung has quality control tolerance that limits the differences between the two. What we will eventually find out is Samsung's error allowance in their panels.

*** For the record, my S3 is s6e8aa0

[Galaxy Note II Original Android Development] Tatsuya79:
No, you get more blue.

Or you mean -9 red and then something like +5 blue.
[Galaxy Note II Original Android Development] Slimer777:
Two parts answer here;

1. Calibrating white balance.

==================

When you have a reddish screen, turn down the 'red in white'. When you have a greenish yellowish screen, first turn up 'red in white' if possible, if not, turn down 'green in white'. The funny thing is that at one point you had a magenta greenish screen!? You said that the magenta disappeared after turning down 'red in white' by -6 to -8 which is the average that people have a reddish screen will do. The key is that after the -6 to -8 you said the screen turned greenish! what that means is that you simply turned down red too much, increase it back up until the green is neutralized. At that point if you think the screen is a little yellowish, up the blue.

You also said that the screen looked washed out after white balance adjustment. WB does not affect saturation nor luminosity of colors. What you encountered was that the veil is lifted and now you see the calibrated colours and you either did not like it or not use to it yet. if you also adjusted chroma saturation weight and you screen is still washed out, there is something really wrong.

2. Screen Modes.

===========

The newer higher end TVs have night mode and day mode. Night mode has a lower contrast and everything else calibrated to that particular brightness and contrast. Day mode has a higher contrast or else you can't counter the ambient light and you may not be able to see at all.

No display can auto adjust its colours to counter all sorts of different ambient lights in realtime. Movie buffs only calibrate the display in total darkness (for dark mode) and normal daylight (for day mode) but dark mode will always be more accurate to the eyes due to no interferance of coloured ambient light.

What we are currently doing is setting a night mode with an addition of Samsung's brightness control. Yes, by changing brightness you are ruining all calibrations (from a professional standpoint) but for the phone, I doubt anybody will notice it.

But either way, having a calibration will still be better than one without. Especially having those original Samsung profiles!:eek:
[Galaxy Note II Original Android Development] aussiebum:

Noticed if SCR isn't enabled the everything looks a bit washed out. With SCR enabled colours are fine
[Galaxy Note II Original Android Development] Slimer777:
The incremented blue is a side effect for his situation because he wanted to remove the red, so lowered the red. Then he thinks it's too greenish, so he lowered the green. Yes, he ended up with a white balance of higher blue but he never intended to do it.

Again, he should have lowered the red (assuming he cannot increase the green), then the screen becomes greenish is what he said. Now take the red up one by one until the green is gone while not reddish. Final step increase the blue to get a desired white. At this point if you cannot increase the blue, decrease both red and green by the same amount until the screen is white. By saying the same amount is a little vague because the two colour have very different luminosity and since the user doesn't have a meter, he will have to rely on this eyes.

---------- Post added at 06:32 PM ---------- Previous post was at 06:29 PM ----------

Good, when gamma is corrected your red tint will either be lowered or removed. I had the same thing on my SGS1! By the way, you have a real high gamma at the low end.

I hope you realize that 'enabling' SCR (I assume you mean you ticked it) means disabling SCR in reality. With SCR disabled your tint is shifted and colours oversaturated to the point between Pre-cal and caled.
[Galaxy Note II Original Android Development] Tatsuya79:
Sure, I thought this could be misunderstood as "lowering red and green together reduces brightness".

I wonder if maximizing the highest color value is great to compensate the loss in brightness after calibration.

Like if I'm R -10 G-15 I would better go for something like R 0 G -5 B +20?

Would this cause some side effects (like banding)?
[Galaxy Note II Original Android Development] Slimer777:
The original master profile was already done in this fashion with minimum brightness loss. Even for the people with the reddish tint, they wouldn't have anymore brightness than a few click of green. But we can see that we have more people who are ok than having red tints so I would only make tiny adjustments in white balance.

Re: [Kernel][28/02][N7100 N7105 R950] Perseus

A good example. Try it for longer time to see if your eyes adapt. Fact is fact, if it is reddish then it always will be and your eyes will not be able to adapt. Turn it down and done.
