Color banding issues - Galaxy S II Q&A, Help & Troubleshooting

Why does my SGSII show banding on colors with ICS?
Examples: Facebook login, when I first set up the phone, ICS dialer background etc.
I never tried GB as I bought it a month ago.
It does the same with AOKP CM9. The banding disappears when using Camera scenario, but that just gived the screen an ugly blue hue.
Is my phone faulty, or is it a common problem to the SGSII which the community has accepted?

It's a known problem, AFAIK. Stock GB kernels had the same problem, some custom kernels took care of the problem with various patches (if I remember correctly, Speedmod's excellent kernel had different display tweaks and there was no banding visible - there's a changelog here which lists them, but don't go flashing it right away - it's a GB only kernel).
Wait and see

So this is a issue on all SGSII on stock ROM?

Well, yeah. First result goes to this older thread about color banding

That's an old thread regarding stock GB rom...

Yeh.. As previously stated OLD ISSUE.

Is the camera pink spot problem fixable in software?

Hey everyone.
I've installed all the latest ROMs from Samsung, updated the camera firmware whenever a new version comes along but I can never get rid of the pink spot...
I've heard thatnsome people used to have it and don't any more thanks to a software update but regardless of what I do, I still have it.
So the question is: should I change it for a new unit or is there a way to fix it in software? Thanks...

which firmware are you using?
the OLD KE7 solved this problem for most users.
are you updating your firmware regularly?
I have tried several roms including stock,CM7 and MIUI but I am having pink spot with all of them
I think it's hardware fault, it will appear on close subjects or on white/beige background like walls, too bad for a so good 8mp camera.
The Arc one is still the best hands down

[Q] "Grainy" display issue?

The display on my GS2 has a "grainy" appearance when used at medium to low brightness. It's hard to describe, but it basically makes colors on the phone look like they have a grainy texture. When stuff scrolls on the screen (pulling down the notification bar, for instance), it looks like partially transparent images moving over a textured background.
Is this a normal aspect of the SAMOLED+ screen? I haven't seen this reported, but I've seen it on all 3 of the GS2 phones I've used. It basically makes the display look like total crap at lower brightness settings.
Are you using a screen protector?
I've had a couple on mine, and have noticed different the quality of brightness and colours between each, particularly at lower brightness levels.
Nope, no screen protector.
What is your Product code & Firmware (PDA, Phone, Kernel etc). Are you rooted and or using official or custom firmware?
try using a different screen mode?

I flashed the following firmware, rooted, then installed a Cyanogenmod 7.1 nightly.
PDA:XWKJ3
PHONE: XXKI4
Date: 25/10/2011
Android 2.3.5
I've noticed the problem on the stock firmware that came on the phone, with the new firmware, and with CM 7.1.

I'm running CM 7.1 -- I'm not sure what you're referring to, or if it's something you can only change on the stock Sammy firmware.
Even just a confirmation that someone else experiences this would make me feel a lot better
I do have it, only visible at a low brightness setting, and even then it's mostly on white/light-grey colors.
I think this is the same issue as well:
http://androidforums.com/samsung-galaxy-s2-international/444844-do-i-have-problem-my-screen.html
Nothing to worry about, just another price to pay for having an AMOLED screen. Search the forums, you'll find a couple more prevalent issues with those screens. As long as it doesn't affect your everyday use just pretend it's not there.
this happened with my old white Galaxy SII. I posted a topic about it a month ago. There are other users who also have this issue, so you are definetely not the only one

[Q] Any ROMS that fix the black crush display issue?

There are several threads on these forums about the video and picture quality viewing deep blacks with both the international and AT&T versions of the gnote. It's a widespread problem that affects almost every unit. And yet there are developers here that are working on ROMS, themes, radios and other custom tweaks as if these customizations could allow me to overlook this glaring problem.
So my question is are there any ROMs or other fixes that will correct the black crush problem? I have read that the gnote might need a forced 24 bit color fix. Or perhaps the Bravia engine might help.
Until the black crush issue is fixed, I don't plan on spending any time customizing this phone, and I probably won't keep it much longer if it looks like a permanent problem. With all of the advantages that the gnote provides, the display is the absolute worst thing for Samsung to screw up because it's the #1 reason why people buy this phone.
Both Roms have it.
Never thought of trying the bravia engine. I will try that

I'm sorry. Both ROMs have the black crushing issue, or both ROMs have a fix that works? And which two ROMs are you referring to? Thanks.
TPC and Saurom both have the issue, as well as the stock ROM.

Your experience with the new ICS roms and Leak ICS rom

I'm actually proof the ICS Phone Bricker 2.0.1 on may Samsung Galaxy SGH I777 and this is what i found on it:
1.-When i use the Talk app and somebody write to me it make a weird sound again....and again....and again......
2.- I must make around 15 wipes and go back to the factory kernel and root again my cellphone and over 3 hours or more left i make my phone works with my service provider because in ever install of this rom not works.
3.- Going crazy trying to recognize SD card on my PC.
4.- Lag buttons
5.- apk's like Android Overclock, or Chainfire 3D Pro Crashes if u reboot your phone.
6.- Takes a lot of time to sync with my Wireless Access Point.
7.- Some native functions on Setting not works.
Please comment your experiences about this ROMs.
Was on the rooted leaked ROM posted by task but I just restored back to UnNamed 2.2.1 after a couple of days. It bugged me that I was not able to view battery stats and contacts tab was missing in the dialer. I hated the wifi bug of it not being able to reconnect automatically.
I really liked that the stock messaging app did not show mms as slide show and I loved the pattern lockscreen (clock, brighter wallpaper and smaller dots). Never did get the weather to show on there though.
For me UnNamed works better. Might try out SHOstock this weekend if I am not too busy.

im on the ShishirROM ICS and i love this thing! i tried phonebricker and another one and then ShishirROM was the last one i tried and i have been on this ever since. i have yet to notice a single bug that i can find... i came from unnamed and i can say that i dont believe i am going to be going back to it since ive installed this. i have had it on my phone for 4-5? days.
I tried Mystic's rom and was not satisfied with ICS, i've been on unnammed 2.2.1 for awhile and with launcher pro it flys. I used Apex launcher but it still seemed that the rom lagged switching screens. I use email a lot for work and hated that the background was black instead of white like GB. Overall, the rom was well done by Mystic no real bugs I could see but I think I am going to wait for our source to drop and hope who ever did UnNamed makes an ICS rom. I can deal with the battery issues of KK6, I gotta have my speed.

We have the i9100 source already and the only real benefit from i777 leaks could be NFC if it were included. Ultimatum is a good ICS ROM which will be rebased soon. Phone Bricker is also good I don't know what the OP is doing wrong. Most of it is just waiting for better i9100 firmware to be released along with allowing time for our current kernels to mature a bit.

I've tried several ICS ROMs and they've all had some sort of bugs floating around in them. I'm currently using ShishirROM ICS and it's been the smoothest so far.
I think a lot of the problems are with the latest UCLC2 Modem. I was having major heating issues and reverted back to KH7. Now all is well.

Did you try different modems?
Nobody else is having this issue as of yet.
3.- Going crazy trying to recognize SD card on my PC.
ICS changed how USB storage works, hope you know that.
4.- Lag buttons
Seriously? These are early stages and every build and kernel update makes things better.
5.- apk's like Android Overclock, or Chainfire 3D Pro Crashes if u reboot your phone.
Overclocking/volt changing does not work properly, its in development by the kernel devs (PLEASE DON'T BOTHER THEM)
6.- Takes a lot of time to sync with my Wireless Access Point.
Haven't heard of this problem before.
7.- Some native functions on Setting not works.
I removed a good amount of bloat, but only things that don't work is the "track me" settings as I don't care for it.
If you want it I could have sent you the apks but nobody has requested for it in my thread.

Oh good Lord. Not only do we have like 2 dedicated ICS threads, this thread serves ABSOLUTELY no purpose. Im not going to allow threads to be started to bash Dev's hard work (THAT STILL IN PROGRESS I might add) and to just whine. If you dont like ICS, then downgrade back to GB. No need to start a thread about it.

SOLVED Screen brightness on ICS compared to Gingerbread

I have been using the same rom since the day I received my Galaxy Note so I am used to it by now since I have been using it for over four months. I even flashed a couple other Gingerbread roms which were nice but I came back to the Solaris Prime rom qickly after flashing. After waiting since the first ICS leak I got bored and flased a custom ICS rom with the intention of playing with it for a while then flashing back to Gingerbread. The screen was bright on every Gingerbread rom I flashed, but on the ICS rom I flashed it was nowhere near as bright. I always use full brightness and never use auto adjust which is what I set it to on the ICS rom. This is the ICS rom I tried out http://forum.xda-developers.com/showthread.php?t=1686320 Now my question is, has anyone else noticed this or is it maybe only a problem with this rom? Are ICS roms not as bright as Gingerbread roms cause I need the screen to be very bright? I noticed the brightness was very dim compared to Gingerbread roms I have used within five seconds of setting the brightness to full and turning off auto adjust. If all the ICS roms are like this I think I will stay with Gingerbread cause this is a deal breaker for me.
EDIT: I figured it out. It is the Auto Adjust Screen Power setting, when checked the screen becomes dim when unchecked the screen is vived and bright. I guess this setting is not in all roms.
Hard to compare since I can only load one ROM at a time. But I never noticed the difference in brightness. I leave mine turned up also as I am frequently outside with my work and play. The 15 toggle mod is not somehow overiding your brightness setting in ICS?
I believe I have noticed the same issue. I thought maybe it was just me, but apparently I am not the only one. I am rooted and running BlackStar rom right now, and I can compare it side by side with my girlfriends stock unrooted note and hers seems noticeably brighter. But even that I chalked up to her not having a screen protector and me having one. But I wouldn't think the screen protector would inhibit the brightness much if at all.
I also have gotten to the point of using full brightness, becuase auto brightness is unusable at times, even indoors.
Are we the only 2? LOL. I have noticed another issue with the backlight today. The screen seemed dim, but every once in a while would get bright for like half a second then go back to dim. I have it set to full brightness, but I tried covering the sensor, or at least what I think is the sensor(gonna have to google that) and it didn't change anything.

Well did you compare when you both stock? Not every screen is created equally. I've seen identical phones next to each other and both have completely different temperatures on the screen (one bluish and one yellowish).

This is not anything that I needed to compare. It was noticable and since it happened I have read about other devices having the same issue after upgrading to ICS. It seem like the only devices this happens with are Samsung devices cause every device I found with this issue was a Samsung device. Not sure if they are putting a limit on brightness cause I know a lot of people said the contrast was too high on the Note but there is clearly something making the screen look washed out with ICS. I want my screen to be bright like it is capable of. I want my whites to be white like they are on Gingerbread.

That makes no sense. I need a dev to tell me they limit the brightness we can use before I would beleive that. And not only that the problem seems to be happening on official firmware upgrades not just custom roms. I do not think its a coincidence that all the devices I have found this problem happening on after updating to ICS were Samsung devices.
I recreated the problem so people can see it happening on their devices. Try this
1: Turn full brightness on and turn off auto adjust.
2: Open the default browser, and Gmail and leave them running.
3: Now go to home and long press the home button and the app icons will popup. Pay attention to Gmail and the browser, and you will notice the task manager icons are much brighter than the apps.
4: Without taking your eyes off the task icons open the browser and you will notice it gets dimmer then the task icons.
5: Now hit the menu button and when it pops up the browser will get brighter. Hit it again it will get dimmer.
6: Now hit the tab button and you will also see the tab icon is much brighter than the app itself.
I have noticed the apps that have the black menu popup get lighter and darker when you push the menu button but the ones with the white menu popup stay the same when you push the menu button. The weird thing is it seems like the system menus, app menus and the launcher are all as bright as they should be its just the actual apps that are washed out. I have only tried two AOKP roms so maybe this is a problem with those roms but it is very noticeable especially on apps that have white backgrounds. I cannot figure out why the whole system is bright til I open an app then the app gets dimmer then the rest of the system.
Lol

This ICS rom I'm using (FJ ucle2#6...is not "darker" per sey .
I'm leaning more toward darker theme features perhaps ?
But I prefer the dark background popups with white letters etc. And I suppose it's possible that the ICS leaks are reduced to improve battery life ?
I honestly can't say, but I do know that my stock GB was like looking into the sun at night for me.
My eyes don't do bright very well ....g
I have the same problem!!!
I use my Galaxy Note (ATT) at full brightness and I have had it for 4 months. Got bored and decided to root it yesterday and installed an ICS rom. The screens were noticeably darker even at full brightness. It was depressing me and I wanted to go back to Gingerbread, but the MDSUM of my nand backup was incorrect for some reason, so I have not been able to do that. Looking around now for some Gingerbread roms to flash today!!!

Just an FYI, - I was downloading another rom from the same team as the one you recommended when I saw your update, so I went ahead and flashed the one I already downloaded. Took me back to 2.3.6, but it did NOT fix my screen brightness issue. I therefore went ahead and took my phone completely back to stock,unrooted and it's all good now.

Thats the rom I use and its super bright. Try it out I promise you will like it.
just pointing out - I agree about the brightness thing.
specially so in my favorite new rom, the latest from team perfection (the one released at the end of june 2012). it's an amazing rom, but it is quite dramatically dimmer in autobrightness modes than GB roms and is in fact so fim in autobrightness modes that I can't see it very well with my old eyes. I had no problem with other roms, and the stock gb rom is MUCH bright in auto mode.
then I take it out of autobrightness and go outside in the sun. it's almost unreadable in the sun outdoors (walking around). reverted to stock nandroid in autobrightness mode - I can read it ok in the sun. reverted to nandroid of the new ics rom. crank the brightness, can't read it, autobrightness is no brighter (maybe even dimmer) in the sun.
this isn't acceptible - the display on the note is amazing, why take away one of the best features of the note?
I cant' even use the phone in the sun when walking now.
I hope someone can find a way to change the brightness levels after the fact - that would be a really helpful tweak for those of us who can easily tell the difference (between readable and unreadable) in our roms.
I've looked through build.prop files but can't see anything there obviously related to screen brightness, so it must be something in teh roms or kernels.

I mentioned this on one if the rom threads and they got mad for some reason. They acted like I was making the issue up. I do not know how I noticed the ICS roms are not as bright as the Gingerbread roms but not many others have noticed. It is insanely evident that the ICS roms do not match up in brightness when compared to Gingerbread. I have also searched the web about the issue and all the devices with this problem are made by Samsung. The big bright screen should not suffer with an upgrade. I want my screen to be just as bright on ICS as it is on Gingerbread. With this issue ICS is a big turn off for me. I am beginning to think that all the reports of over saturation on the screen of newer Samsung devices have forced Samsung to put something in the newer ICS software to control the problem that some had with the saturation being too bright. I really hope someone else notices so it can be taken seriously and someone will give it some attention and fix it.
cool, yea I read that... LoL, I felt bad for you.
I think I may have found the possible culprit, if devs are doing this on purpose at least.

I'll look at this tomorrow and see if I can brighten up my new favorite rom, team perfection (the june 28th or whatever latest rc1 version is).
