Hi there,
There is a green tint in the right part of the screen, it's more noticeable in low light and grey colors. Using PA Rom, but I think is not related to it. I use 66 hz screen oc, but the problem persists in 60 hz too.
Searching in the web I've found that may be burned due to oc, but in the forums people have been using it for a long time without issues at higher hz. I found a forum with a man with the same issue in miui stock without screen oc, but it got fixed, so maybe it's software related.
I think I'm going to flash stock miui and see if it happens again.
Anyone with the same issue?
Your screen is fried bro

Yep, that's what I think. :crying::crying::crying:
I'm thinking about flashing stock and use the garanty. But in daylight or light theme is not visible. Probably I'll wait to see if it get worse to contact the seller.

Hey guys quick question
Me and my girlfriend both have the SGS but I noticed today that he screen has a weird yellow colour when compared to mine.
Like my blacks are black, where hers just seem off from mine even at low, medium and full brightness, power saving lcd thing off on both.
We are both running JPU.
Is her screen dying or is it faulty? if so should i contact samsung for a replacement model?
Thanks
Hi
I have an issue where my screen is much darker than those of friends of mine, both with brightness set to full on all phones or with auto brightness on. I didn't notice it at first but now that I did it bugs me like hell. Maybe its related.
Depending on country and service center it shouldn't be too much of an issue to get a replacement screen / device. It goes without saying you have to roll back from JPU to the original froyo for device.

Running any custom kernel with colour fixes etc? I think some roms/kernels tweaked the settings
I think its possibly some variance in the manufacturing process. Mine has a blueish tint which i find quite annoying, but only appears when looking at it from the left hand side
Thanks for the responses guys, we are both running stock JPU roms but ive contacted samsung and they said they will have a look at it :/
I played with my NC nearly one week and I like it. But I want to know dose anyone notice the screen of NC is flickering. If you couldn't understand what I mean, please refer to below video,
http://www.youtube.com/watch?v=iDnBSWF44rM
it is not so obvious in real world as in video, but it is noticeable and uncomfortable. I have ipad with IPS LCD but never find this kind of issue. It like some kind of low fresh rate issue in early PC screen, so I want to know whether it is possible to fix it via adjust screen refresh rate in OS level.
Your comments are welcome!
Mine does that but only on the gray background, otherwise I don't see any flickering.
I exchanged my first NC because of this issue. The salespeople thought I was nuts until I demonstrated it for them. My new one still does it but MUCH more faintly and not all the time. I do believe that Barnes & Noble is aware of it (or at least that's something I read in another thread here somewhere..).
It seems to only happen at middling levels of brightness. My first NC exhibited the issue under very specific settings and times, the brightness had to be set between 20%-40% and I had to be displaying a solid area of mid-range colors. I saw it all the time when the screen would dim to display a menu.
From personal experience, you MIGHT be able to get a unit that's better if you exchange. It does seem to be a very common issue, though. Rumor has it that it might be fixable through a firmware update.. we shall see.
I had a pocket pc with this problem many moons ago...The fix was to adjust a trim pot on the display...
No idea if anything like that would apply here, but just wanted to mention it.
I do have similar problem, could any people advise on how to check the refresh rate and increase it?
Many thanks.
Are you planning on rooting or installing another ROM on your Nook? The overclock kernels fix this issue.
from what I see there in the video, if that is what you are seeing...not refresh rate. Rather it looks like a cycling in the backligt control. Almost looks like the PWM duty cycle is out of wack...would explain why it happens at mid range of the brightness.
My first nook color had this problem, I solved it by leaving the brightness up all the time which seemed to prevent it. I got it replaced for other display issues, and my new one doesn't flicker at any brightness, so yeah it sounds like a defect.
Not a defect. It's a problem with stupid coding in the backlight driver.
They set the PWM (pulse width modulation) rate too low, at 40Hz if I remember right. It's easy to fix by setting it up to 60Hz in the driver, which I did in my old Quickie kernel. Totally gets rid of the flicker, and I've seen no side-effects, nor have any been reported to me.
I don't have the time to keep up with the kernel anymore, and for some reason no other kernel dev has pulled my driver fix into theirs. You might talk to Dalingrin or one of the other devs if you really want it, and put them in contact with me at [email protected] and I can help them get it integrated into their kernel.
Can you link to the github commit?

Hmmmm.... my Nook definitely had the flicker issue on most gray colors, especially at dimmer brightness settings. I'm not using your kernel, but I am using Dalingrin's. I haven't seen flicker in months. Could this issue be limited to the stock ROM only?

It appears that way from my experience. I was running the dual boot package with stock and CM7 nightly.
The stock rom flickered very noticeably on greyish type backgrounds. Using CM7 and now Phiremod, the flickering has totally gone away.
Actually the fix is already in init.encore.rc:
Code:
write /sys/devices/omapdss/display0/timings 68000,1024/70/200/40,600/10/11/10
That said, it's going into the driver too.
Though these 4 pixel dot only visible when brightness is at 60% and specially visible when background color is black. Can Dead Pixel Fixer app fix it? or I have to do something else.

see if it's a hardware problem first by taking a screenshot and seeing if you can see the pixels in the screenshot. If you can, it's a hardware problem, if not, then I guess you can solve it somehow, either with that app you mentioned or flashing a new firmware

I took screen shot, there was no problem in that picture. I tested many things, and the result is - the dots are only visible in Black background when brightness is above 50%. Otherwise its not visible at all. Phew....... That's a relief :victory:

OOHH woops I meant if there are dots in the screenshot, it's a software problem, and if there aren't any, it's a hardware problem

My history:
Buy Xperia V with .489 no have stuck pixel (60%, 80, 100%)
upgrade to .140 increase brightness at 60% and now have one stuck pixel (green). :S software problem
im using .140 deodex and DoomKernel or vKernel
note im not sure but I thought I saw it before unlocking the kernel and put vKernel/DooMLoRD kernel did not have this problem.
Hello.
Just bought this terminal, D410, and when luminosity is 0% or close there is a little but noticeable flickering on the screen. It's better seen with a white background.
I read some LG phones had this issue, can you confirm it happens with yours, if not I'll just try to replace it.

looks like that is normal, mine does the same, i was wondering if it was only me, but now i know i am not alone
besides that the phone is great so no complaints
Ahhh and mine is an L90 ( D415)
so looks like that "issue" happens across similar models
Yeah, I thought so. Looks like G2 has the same problems.
The flickering is minimal so I won't bother too much. I can always use screen filter
And yeah, this phone is great!

That's actually a normal thing to happen, something to do with the frequency at wich the leds pulse to appear "less bright".
Turn brightness up and it will go away.
Hi.
mine also has this problem. For me, it quite annoying, I do not want to use screen filter.
Is there anyone know how to fix it?
Does it happen on non-stock rom (slim, CM...)?
Edit: I have flashed Slim rom. It is great, and I barely see the flicker. In stock 5.0.2, it is annoying, and in Kitkat it is unacceptable for me (I think my eyes are sensitive).
Will anyone try to modify the stock kernel so that the backlight pwm will increase?

Which Slim, L or M based? Try using a higher minimum CPU frequency (make sure you pick a governor that allows setting frequencies), I remember reading that it's what made stock Lollipop better regarding screen flickering.

slim 6.0.1 and cm 12.1. both are almost flicker-free (infact i think i see a little bit, but i dont know if this is just my imagination or not). in both stock 4.4 and 5.0, the flicker is clearly seen.
thank for your information, i will try.
Edit: I have tried with Kitkat v10f. No luck I just dont want stock Lolipop, it is just too laggy compared to Cm 12.1
Hi guys,
My phone's screen is very mildly flickering . Very mild . It's like light blink. It happens mostly with white screen background . It is quite a concern cos am worried this might become worse as time goes by . Anyone knows what's causing this and a possible fix ? Btw this happens in safe mode too
Pls someone reply
It sounds like a hardware issue, I would take it to a Samsung Store and see what they can do about it.
Mine just started doing it, but my note 8 is already gonna be shipped to them to fix the burn-in issue im having. Hopefully it will fix the flickering aswell.

Hmm I too feel the same but it is only very mild . Only when observed very closely the flickering is visible that too happens only in white screen

Doesn't look like a burn in issue for me . Looks more like something wrong with ambient light sensor.
