Hi all,
I'm looking at a Galaxy Tab 10.1 for a friend: everything seems to work fine except the screen is a bit stuffed. It really looks like the colour depth has been set to something ridiculously low, but I can't see anywhere to change this. See attached images of the stock wallpaper and the second test image posted by asolanki in this thread: http://forum.xda-developers.com/showthread.php?t=1603650.
I had to take pictures of these links: if I just did a screen shot and emailed the images then although the screen shot showed the banding / colour depth problem, the emailed images looked fine.
I've done a factory reset, but still the same. Could this be a hardware issue?
Model: GT-P7510
Version: 3.2
Kernel: 2.6.36.4 [email protected] #1
Build: HTJ85B.UEKMP.P7510UEKMP
Has anyone ever seen anything like this, or have any suggestions? If it's a software problem, could rooting the device and/or installing a custom ROM help in any way?
Thanks,
Barney

Rest assured that is an hardware issue, and a screenshot (taken with the software) won't show us the stains on the device's display you will have to take a photo of the display and post it, so people can compare it, your best bet is to put that tablet on warranty service :|
The same thing happened to my tab yesterday. I left the tab off during the night and when I fired it up this morning it was OK for about 5 minutes. After that the banding/colour depth display problem returned. It sure looks like a hardware problem. Not so good for me since i bought my tab in the US and the without the global waranty (I live in Europe).
SOLVED:
I removed the tab from its Belkin case and placed the tab in the fridge for 30 minutes. After that it looks as if the tab is OK again.
That's weird - I saw your post and wondered if it was overheating, so tried the fridge thing myself. Unfortunately, it didn't work for me, so looks like it's stuffed! Oh well - hope yours stays working - a bit tricky to have to sit in the fridge to use it!!!
Cheers,

Hello guys,
after flashing batista70's ROM, I started to notice that on the default wallpaper, there was heavy color banding, as if the bit rate of the colors dropped.
For example when I use the microbes live wallpaper, the microbes are much bigger and it looks like it's zoomed in, plus the dark background, instead of having some smooth grey areas has a net separation between black and dark grey.
I've tried flashing stock ROMs back, but it didnt fix the problem.
Do you think that if I send it to samsung saying that it happened after I updated it via Kies, are they gonna fix it?

If something happened to any hardware component of your phone, they will fix it.. But only if you pay, unless you use a JIG to reset the custom binary counter...
I can't imagine why a ROM should damage your phone, you should try to flash another kernel...

Im having the exact exact same problem. Kind of dissapointing. I thought rooting and flashing roms made better. Its a small problem but an annoying and ugly one. PLEASE HELP!!!!
Funny this, I have the same problem after changing screens (so a hardware, not software, change). Did you guys find out what's causing this?

possibly display drivers issue?

That user suggested a re-flash
Any news on this issue? I just changed my cracked screen, and when I plugged the new one and turned the phone on, image was perfect, then 1 second later it went all strange, with heavy horizontal banding.
I didn´t have a chance yet to flash new FW because my S2 has a broken power flex button, I´m waiting the replacement one to arrive in the mail, but I would like to know beforehand if this may be just a software problem. If it´s hardware, I think I´m screwed.
Thanks!
Hi all,
After cracking mu i9100's screen, I've replaced it with a Samsung replacement kit bought online (complete screen, led and digitizer). Install was easy and the phone works again. No software/firmware changes made.
The problem is that it looks like the color depth is greatly reduced. It's like changing the color depth on a computer from 24 to 8 bits. There are no other artifacts and all cabling seems secure.
After searching a lot online I can't really find what's going on. Would anybody here have a pointer for me? Thanks a lot in advance!
Update: Apparently this can also happen in software: http://forum.xda-developers.com/showthread.php?p=21780618

Take a screenshot in android and upload.
If the screenshot does not show this then it's the hardware.

@Omega: very good idea!
The problem was solved by completely flasing the phone again (The Feb 3 leaked ICS in this case).
I can only speculate that there is a discrepancy in firmware/driver which occurred when the phone was flashed before; likely that the old screen's firmware probably was also updated somewhere in that process.
At any rate, colors are normal again.
Hi. I have a galaxy tab 10.1 wi fi 16 GB tablet. I just recently replaced battery, and lcd ribbon. Also, downloaded ICS and now using that wtih version 4.0.4. My problem is the pictures are not all 1200x800 resolution. Most are like shadowing of water scene, you can tell it is water, but very plain looking. the camera pics look the same, both before and after taking the picture. Samsung rep said it could be hardware problem, wants me to send it in for repair...I would like to try and fix it myself. Anyone have any idea what the hardware would be that is causing the problem? See the attached picture as to what the screen looks like. Any help would be greatly appreciated!

I've noticed the same here. No solution yet for me.
It's most likely your screen cable, check if it's damaged
Were you able to figure this issue out?
anyone find a fix ?
Hi there,
Has anyone found a fix to this problem.
My samsung galaxy note 10.1 resolution seems to have changed like reported (in the screenshots).
Please let me know if anyone was able to fix this.
Thanks,
I have the same problem with my samsung 10.1 tablet! Help
Hi there, dear Galaxians ;P
Long story short... I got my 3rd in a row Galaxy S2, but this one is a brand new, never opened SOB (I guess this is allowed here, if not sorry). Last two S2's were used. Nevermind.
Those first two has awesome saturation. This one was UGLY! Whites were pinky'ish, Green was eye-popping, and Movie setting didn't help a lot. For those who has normal saturation on Movie setting it was like I had Dynamic turned on. Well, I tried all possible software to make it look good. Then I found a post about it where one of our fellow friends wrote, he upgraded firmware and saturation issue were gone. Well, I wasn't happy hearing that as I consider myself stubborn and conservative 2.3.6 GB user. I guess when I buy Galaxy S 2000 in the future I will downgrade to 2.3.6 anyway, unless they invent week-lasting batteries with 5" or higher screens. Whatever...
Since I found aforementioned thread I was considering firmware upgrade but with another reason. What came to my mind was: "Geez, I got my previous S2's came with JellyBeans on borad and each time I downgraded to GB." Getting things together I found a connection here: "Is this possible that JellyBean can calibrate colors and saturation properly?" Well, my last, brand new S2 came with ICS so it wasn't good calibrated either. I decided to try it and upgrade to JB but then try to downgrade again to GB. As far as I try to have control over my phone I use RootAppDelete and Disable Services apps. I turned off some stuff and I was unable to run Automatic Updates (instead of Kies crap). Well, I messed it up a bit so I had to restore factory settings (all stuff backed up with Go Backup of course). After all I thought: "Why not to give a try again before upgrade?" So I did it. First, I wasn't able to saw a difference as I found out bad saturation after installing Go Launcher and all stuff to get my own icons on desktop and specific wallpaper. After I restored everything I was a little confused, but I checked few icons containing a lot of white like Gmail. It hasn't blinding red color on it and white was white not pinky! Hell Yeah! Then I shuffled through some pictures which were definitely oversaturated and they were fine.
Final conclusion: try NOT to use any RAM and battery eating apps as they never do what you expect, trust me, I tried them all. I don't know if this is universal solution, but in my case after flashing new ROM I had to restore factory settings (stock thing, not CWM or else) to get solved saturation issue.
I hope some of you will try it and mayby you can sort it out, too. Happy Trying.
Let us know if that worked for you too.
I decided not to edit previous post as it was a little too fast to say it was solved. Well, after re-flashing firmware my eyes were probably misled by black screen during flashing. So flashing ROM wasn't necessary and did nothing, to be exact.
Anyway, there is a chance to repair saturation problem with Soft Screen Tuner app. I found it somewhere around here. I gotta tell ya, it really works. This time I'm sure. Although, it doesn't work completely. I don't know it this is a software isuue or it doesn't work with SGS2. But there are four groups of changers in it, but three working: sharpness (don't care), RGB sliders ( use R-235, G-245, B-245) and Temperature (use 7000). That looks like too much of red colour is gone that way. This tool has saturation slider but it don't work for me on 2.3.6 GB
Hi,
Just got the phone yesterday and I'm completely in love with it, having upgraded from a OnePlus 3T.
However I have encountered a display issue I beleive. It's a bit difficult to explain but when animations are preformed on the screen, for example when pressing buttons in the settings, or when the wave animation that comes up when plugging in the phone for charging, the color in the animation looks like static on a TV (happens both in dark mode and light mode). I'll upload examples here since it's a bit difficult to explain like I said. Anyone else that has encountered this? Haven't found anyone with similar issues so far, or maybe it's supposed to be like this? Do you see this it like this when plugging in the phone for example as well?
Did factory resets, tried starting in SafeMode etc but no luck. ASUS support told me to contact my retailer since it's a brand new device.
Thank you!

That animation is intentional. Nothing to worry about

Thank you for your reply! So the static-looking colors/theme in all the animations are intentional? If you also have the phone, does it look the same for you like it does in the videos I uploaded?
Sorry for all the questions, just want to be really sure before I contact the retailer

Yes, it is an Android 12 design choice made by google, as you can see in the article I linked, they had to reduce the effect because it was too strong during the first 2 beta versions. So if that is what you are talking about, do not worry its a design choice!
