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 :/
Hello friends! This forum has been of great help to me and my device for a very long time. Appreciate all the help and guides provided here for the not so tech savvy people like me.
Just wanted to check for an opinion from you guys here. I have been having this ghosting problem on my i9000 where on a clear white screen, there is a fixed ghost image (or whatever you call it) of the pattern lock screen hard on embedded.
This is only visible on a clear white background. I have enquired in the local shops here (in Malaysia) but they all seem to suggest changing the screen and the digitizer but cannot prove that it will work and I would have spend more if the problem isn't fixed.
There are 2 links of the problem I mentioned here and I appreciate any suggestion from you forumers as to what would have gone wrong and the most probable component that needs to be changed as I believe people here would have seen more occurrences like these compared to the local stores here. FYI, the warranty period of my phone has already expired as it is a 1 and a half year old set. Thank you very much in advance!
p/s: i would love to add an image link of the problem but due to being a new user, i am unable to show this problem to you.
could you please upload those images on upload sites
The link are as below

I have the same, but less visible.
It's one of disadvantages of OLED screens - screen degradation. The more particular pixel is used, the darker it becomes.
In our example - previous owner left phone with lockscreen visible and long timeout set for very many times.
Only way to get rid of it is OLED screen replacement, warranty is not covering the screen degradation. Remember that the screen is integrated with digitizer.
Hi fellas,
We know our SGS is old but it still is very much capable. One thing with this device that can't be worked out is the amoled burn-in. I had my SGS's screen replaced twice due to burn-in, and some of you might think that "you've had your brightness settings too high for a long time" etc. The thing is, I've been using lowest brightness setting since I had the second replacement and for over a year burn-in still take effect. I know SAMOLED is superior in terms of overall display experience but the way I use my phone isn't the same as I use it when I first had it (meaning I'm used to looking at my screen and I don't bother the contrast/deep blacks anymore as I used to). I wanted to have a peace of mind using the device for long (4) hours browsing the web or playing a game or using an app without constantly timing in my mind that the status bar or clock is now a little more burned than yesterday, something like "at this duration use, you're blue subpixel is 0.00001% weaker". Those who suffer the agony of watching a burn-in on their displays understand this. So I was thinking of replacing my screen again with the SLCD from i9003 and I wonder if someone already tried it out or if it is possible?

Areas of the screen not registering touch input in most cases is a hardware issue with the digitizer. Loose digitizer connector may cause similar issues, but the only way to check is to open the phone. Opening is not easy and there is a high risk to damage the body. If you decide to go this way, my suggestion is to get new front and back panels + screen kit and to transplant the rest into the new housing. It's also a good time to replace a worn battery or a faulty camera module.

some times the screen back to full funcanlity
and please help about the other problem with the brightness .. its look like one of the sensors is broken in the phone .. maybe its the problem ?
When Auto Brightness is set to Off, the phone is not using the light sensor.
You'll have better chance to get help if you provide some basic information about your phone:
- What OS version? (KK, LP, stock, custom)
- Was the phone factory reset after the last OS update? (highly recommended)
- Do you use any applications that control screen brightness? (like some picture viewers, barcode display apps, etc.)
You may fix the brightness issue (most likely software related), but non working digitizer on parts of the screen is hardware related and no app will fix this.

lollipop not root and other .. i deleted everything , did a soft reset not the hard type . no but i download lux to see if its help and it doesnt help either
The only thing left to try on a software side is factory reset the device. Many users report it clears various OTA Lollipop update bugs. The process takes about 10-15min, the OS will go through Android system update process again and the device will be reset to factory default state (don't forget to backup all your data). During the initial setup process don't restore your online account backup, make clean setup. Test the screen and digitizer before installing any 3rd party apps. Make sure your screen protector (if you have one) is not bugging the digitizer. If you have the same issues, then it's definitely hardware related (screen/digitizer assembly or connecting ribbon cables).
So my display after being replaced 2 times in 6 months started flickering. My phone is very hard to be turned on because of the green flickering.
I just want to upgrade to a S6,S7 Edge or non edge. i just want to know if they have the save problem with displays ? I want to have a phone at least 2 years, can you recommand me a phone like that ?
I was just considering switching to a iPhone even though i prefer android on phones ... o how are S6,S7s displays ? Samsung still have the same problems?
Samsung improved a lot on screen quality in S6 and after, so you should be okay

Wow that's amazing. Been using samsung s5 exynos version for the last 1yr. Never had that kind of problem till date. And it have the same display as snapdragon version. And on comparison I found that this is by far the best display out there when compared to other brands.
Maybe perhaps you might be having a faulty unit from the begining.

I have the same problem here with the display and it's not a software problem (same by original os 6 and same by cyanogenmod 14).
After the temperatures are under 10 C. i can't open my s5 with home button i must do it over the power button.
Using S5 for more than 28 months still I have not faced any issue. I just had to buy new charger apart from that not a single problem and yes I mess up with my phone so much but I still working and no display failure yet. And also I have dropped it many times, it still refuses to die.
You are just having a defective model or some internals of the phone are messed up. Because Samsh*t produces one of the best displays..

Maybe thats a point, but shouldnt only the processor be different? I assume the display is.the same for both...

Its not a good sign. Try disabling your light sensor. Even then if you experience such a problem than it means that your flex cable that attaches the screen with the motherboard needs to be changed.

Hi,
Yes and expect the same problems with the following generations. It's an amoled screen thing. The green colour happen when there's a colour displayed on the screen for a very long time (for example, I have a green on my screen of the size of my keyboard).
I think a solution to this problem is to set the display to turn off after 30s (it saves battery too) and maybe, if you're using a custom keyboard, change the colour from time to time. Use the brightness of the screen to a lowest which would still be comfortable to you (and auto unticked).
This last tip alone is enough to prevent greening. My flickering happened after an incredible fall (it had a tempered glass so the screen was safe). The flickering showed green what it had in memory.
Samsung has a 2-year guarantee for its products so you shouldn't worry for that period of time. Problem not solved, replacement.
Best of luck

The funny thing is i already did "by mistake" all the tips you said and still have this. Never dropped the phone though. This problems seems very big though, i expected a burn in to be the biggest problem, but to have flickering at a level that i cant turn on the phone. I wanted recently to switch to a Nexus 6p, but knowing that it uses Amoled too, its a bad ideea. So the only "solution" is to switch to IPS screens? (btw i want a phone that holds on for at least 3 years)
In my research thus far, the AMOLED screen technology is to blame. When the display circuits get old or damaged, they don't sustain current at low power settings. In LED screens, a back light controls brightness, but AMOLED screens send current to each pixel for brightness control. If the circuit is damaged, or any corrosion has built up inside, this could attenuate the current below the point required to sustain light flow. I see this problem with some LED and CFL lights on motion sensor switches. Just enough current goes through the motion sensor to keep it's circuits active, and that current causes a flicker in the light.
With the screen though, since the problem is only resolved when you increase the brightness just a bit above minimum, it seems anything that lowers the display power (auto brightness for example) will cause it to flicker if this setting gets too low. I also noticed that before the screen locks on timer, it dims to low power for a few seconds and flickers as a result. There are apps that attempt to resolve this by putting a translucent black screen over your desktop and apps. This keeps the power up on the pixels but adds a black overlay, kind of like a screen filter. You can adjust the darkness if you need it to save your eyes when reading in the dark but it doesn't help save power any. They also require a rooted device, which could void warranties. The reason for this I believe is because apps are supposed to operate in a way they don't intrude on each other, and a filter that lays over your screen does in fact alter the output of your display rendering. With the added security concerns of these apps possibly collecting screen shots and sending them to another site, I would avoid this. Best to use a physical screen overlay you can put on or remove as needed as long as it doesn't interfere with your touch screen options.
Ultimately, these devices were meant for replacement every 2 to 3 years so if you're like me and you like to make your investment last, best thing to do is apply any work around you can come up with. A repair shop may be able to wipe the circuit boards down with a solution that clears away corrosion, but it won't repair any weakened pixels. I'm still using a Samsung S5 G900F
- And i finally got this fixed. it sounds like the reason for this is that since the latest update your phone cannot decide whether to use hardware or software back light settings. I managed to make the problem go away by doing this:
Go to settings >> system >> About device.
Find "Build number" and click 6 times fast on it.
You will then get the message saying: "You are now a developer"
and then go back to Settings >> system >> Now you will see the "Developer Options"
Now go to Developer options >> Drawing Section or Rendering Section >> Find "Turn off hardware overlays" or "disable hardware overlays" >> This will force the phone to always use GPU for screen adjustments. no more flickering.
but If I turn the brightness ALL the way down, it still flickers like crazy, however, if that's the only time it'll do it, I consider that a win.
