[Q] Screen darker than stock screen - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi,
I already asked this question at Darkys forum thinking that it was related to the ROM. Well I did not get a useful answer and maybe it is not ROM related.
Anyway a friend of mine got a S2 some weeks ago and I was curious about the difference in screens.
We turned our screens to 100% and to our surprise his was undoubtly brighter and had more contrast.
I remember reading a test about the two screens and the result was that there is no big difference...
After that I compared my SGS with Darky 10.1 RE with a stock SGS. The screen from the stock SGS is also brighter and has more contrast than mine. How can this be?
My phone is ~8 months old and his is ~4 months. But I sent in my phone for repair ~2-3 months ago because my screen randomly got horizontal/vertical lines. I got the name and adress from the company where I sent my phone to from Amazon(I bought my phone there). So it was not Samsung who repaired my phone.
Nevertheless my screen should not be less brighter or contrast than the screen from my friends phone.
Does someone know the cause of this?

Maybe because of different kernel? Thinking of vodoo kernel handling the amoled settings different than stock kernel? Have u tried the vodoo control app to adjust screen brightness?

I downloaded the newest vodoo app but I can only change sound settings.
And I am using Dark Core 2.6 which is, as far as I know only based on vodoo kernel.

[Q] Problem with the screen's colors.

Hello, I bought my I9000 about one year ago. My brother has an older I9000 and many friends have newer devices. I just noticed that my I9000's colors are weaker and un healthier compared to other devices.
The colors on the screen are weaker, especially the blue colors. I don't 100% sure but I think that more colors are weaker. I took a shot of my galaxy near my friend's galaxy when they both running the same facebook application.
My galaxy is the device on the left.
It's very noticable and very annoying since it has to be exactly the same. I'm not sure, but I think that the problem was since the first day I bought it. I just noticed it few days ago when I used my friend's galaxy.
Any advice?

check your brightness level
Settings - Display - Brightness
or if your phone was rooted, and the rom/kernel has voodoo controls, you can make your phone twice the brighter as normal. my lowest brightness in settings (with voodoo controls RGB multiplifier and gamma hack) is just as bright as the iphone's MAXIMUM BRIGHTNESS. or i think mine is more brighter. (WHAT MORE IF I SET MY BRIGHTNESS IN MAX? LOL)
First of all, thank you for your answer.
I'm using full-brightness all the time. I do have darky rom, your voodoo suggest is very interesting, I'll check it. But any way I'm pretty sure that it's not the problem. He's using the same rom I used a few days ago (DamianGTO) and still he had better colors when I used it.
I have pictures of the two phones but I can't upload them to the forum because I'm new.. I'll upload them after I'll get the permission.

SGS has two kind. the Super AMOLED and the Super Clear LCD. the amoled has brighter color compare to the clear LCD, and cost higher than the super clear LCD.
the super clear lcd is just like the iphone4's retina display

Same here, My SGS from is one year old and I just got my girlfriend a brand new SGS, hers is stunishing bright and crips, mine looks decolored next to hers.
This is "normal" behaviour on AMOLED screens, they bright so much that they deteriorate in time, you must have noticed some burning in your screen, specially in the clock area when having an all white screen. Our screens are just simply more burnt, that's why don't look so bright as a new phone
Well, as I said, my brother's older I9000 had better colors, so it's not about the age of the phone. Any way, I flashed a kernel that supports the voodoo colors change, and I changed the colors. Now the screen's colors are way better, and even better than my friend's I9000... So it's all about the colors settings. Now I'm happy with my screen

[Q] anyone in UK with a good screen? (gamma test)

Recently upgraded from a black S2 to a black note (which i love) then learnt of the whole screen issue (black clipping/crush)
ive trailed through soooooo many pages and seems very little evidence of anyone who has done the gamma test pattern and had a good screen
My gamma result is that i can see all the way to the number 4 and then it turns black (i have blocky grey squares for example when there is a scene change during a video and the screen darkens)
my question is is there anyone in the UK with a good screen? i am within the 28 days so i guess they would swap for a brand new note but dont want to go through the process if there doesn't seem to be any good screen units in country!
(i realise there is a member supercurio working to correct this in ics but some people saying it might be a hardware issue since other solutions are simply shifting the values in the gamma test to 6-7 so i would rather have a good screen if possible)
I think its a software and not a hardware problem, but I read the threads on this long ago. In day to day use I can't even tell about the black leveling off, so it doesn't matter to me. If I were you id just stop looking for problems in this amazing device because if you look you'll always find something wrong.

i'm with you on what you said at the end...but the blacks on my phone are more grey and if i watch videos/youtube etc its obvious (actually prefer watching stuff on the s2 and that goes against why i wanted i bigger screen)
i did specifically want to know if there are phones without the issue in the uk as i'm still within 28 days and eligable to swap the unit
regarding if it is software - people still saying the problem is there who have flashed ics though?

Samsung may just not care about it with ICS and things like that, exactly why a XDA member is working on it instead. But since you just got it you might as well swap it quickly and see if it's better. Personally on my note (it's not from the UK) I don't notice this at all, just a yellow tinge sometimes (Damn you pentile!)

[Q] Display quality differences between two SGSs?

Hey,
I've got the Samsung Galaxy S (classic version, distributed to Europe) just like my brother or my friend. When I look at my and at someone else's SGS, I can clearly see the quality difference of the displays. My phone looks much better, the colors are more natural. We're using the same fresh ROM, even the same kernel, and everything. Can someone tell me how it is possible? Did Samsung released more "versions" of i9000s with improved displays or something like that?
Thank you.
They didn't release 'new' versions, its just some are wierd. My friends i9000 has a pixelated and washed out display. Just happens i guess. I got a good one, its going strong like yours.
With mine being a couple years old the screen has a nasty green tint to it, or I should say used to, until I ran the colour calibration. Looks perfect with a little tweak. Big tweak actually
GT-I9000 / SEMA / SLIMBEAN2.3
AMOLED Displays lose brightness and colour over time. I really noticed it when my display was replaced by Samsung. Now the colours are bright again.

[Discussion]Screen Burn-In/Stuck Pixel.

Ive seen no threads on this issue so I decided to make one! But I wanted to know if anyone had any! Personally I had one stuck pixel on my tab s. Yet it was really hard to see I later got it fixed by doing a stuck pixel remover video for about a couple of hours and later installed discreet blue theme. Now its not there! I own the tab s 10.5 Wifi.
So... Has anyone else got a stuck pixel or an image burnt into their screen? Let me know below! Could be useful for others buying this tablet!
I've had the Tab S 10.5 LTE since release, use at least 8 hours daily for work and haven't got any issues in terms of the screen degrading like burn in or stuck pixels, have thoroughly checked to be sure, might have just been a one time thing, generally take years for a burn in on Amoled but even then I have had other AMOLED screen devices for years without a problem
No burn ins on my unit as well , im using the 8.4 as my primary phone and gps. Im always at 1/16th brightness. I also have a 4 yr old 7.7 slate, no burn ins as well. Seems like newer amoleds are not that prone to burn ins. Just to add, im using an all black theme.
Somehow (turning brightness all the way up all the time) my friend burned in a new note 2 in about 3 months. He used his phone a LOT as well.
My Tab S (about a month old now, auto brightness below 10-20% using Velis Auto Brightness, not much used) is perfect for now. However I saw the two 10.5" samples heavily burned at the local mobile shop. Also saw two months old Note 4 heavily burned at the same mobile shop. So it seems burn-in problem with this latest amoled screens still remains.
Thank you guys for your response! Yeah turning the brightness up to 75‰ is how I got mine. That was when I first got my tablet and had it on 75% for the whole month. I want to walamrt the other day to see the samples. The screen seem imrpoved from when I got mine. I will try to use a autobrightness app
Thread should now be a discussion thread about the burned in pixels. Guess I made it look like a question. Thanks forum mods for telling me about this problem and moving the thread back!
I assume this thread is for burned-in and stuck pixel questions/discussion?
If so: I just went to a couple of local stores to test out the Tab S, with an intention to bring one home. I didn't so far -- all devices (4 in 2 different shops) had pretty severe burn-in from the demo programs that Samsung installs and runs on the devices in the store. A couple of them so much that it was actually disturbing for things like browsing plain web pages (white background); you could read the "inverted" text that had burned in.
One store anticipated the device had been on for 10 hours a day since somewhere August last year, which would make it around 10*6*40 or about 2.400 hours of use -- presumably close to max output on the display in "demo mode".
This caused me to hesitate... is this a common problem with the devices, particular to early models, or just something that happens if you run it for too high output -- or will it happen eventually to all devices? A life-time of less than 2.000 hours seems quite low to me in any case.
Also, when/if it happens, are there any ways to "reset" the screen again, or is the damage permanent?
I have a ~2 yr old S4 that does NOT have any burn-in, but I also use that much less, not at 100% brightness and usually with varying content on the screen. I guess the display technology is similar even if the Tab S is a much newer device.
I never had burn in problems in any Samsung amoled devices (since S1).
Just made sure box was sealed and auto brightness was always on.
Actually, I personally have a worst experience with LCD with light bleed and other issues.
Yeah, No problems with my 10.5" Wifi , I watch a lot of Animi and always run it fullscreen, so no black bars, also i set brightness to auto -5 when i am using it indoors.
No stuck or dead pixels, fingers crossed.
John.
@pacc @tinderbox(UK): That sounds re-assuring. Sounds like it's still safe to go ahead and acquire the device (in my case probably the 32GB WiFi 10.5" edition). Hopefully this is the general experience by most people then.
On the LCD bleeding, then yes, that can be quite annoying too!
Just be glad you did not buy the 8.4" version as that is having some problems with the display that might affect some people.

John
I have 8.4 version and the screen is in perfect condition.
You need to use one of the screen test app to check for any problems with the screen before you buy, or the time runs out for you to return the tablet for a refund.
Some people are not bothered, good for them.
John.
I'll test it out thoroughly while it can still be returned. Thanks for the heads-up on that issue as well
If you really want to find every possible quality problem with the display, view a light gray screen in the dark, using a screen test app , set the brightness to low, look for circles and clouding, as well as dead or hot pixels.

I have an S4 I bought used and have used for about a year. It is getting heavily burned in. I am questioning how long this display will last. Hopefully by the time I need to replace it the screens will be cheap
Sent from my SM-T800 using XDA Free mobile app
What was burned-in on your S4 , notification bar?, home screen icons? , were you using an navigator app? , how high did you have you brightness set?
Using an low brightness setting can reduce the change of screen burn-in, but if you live in an sunny country you most likely have the brightness set virtually to max to allow you to see the screen outside.
Thanks
John.

I decided to check for stuck pixels on my Tab S again. Turns out, I have 3 stuck ones now! They are really really tiny that I can even notice them. Took me a minute or so to search for them. In order to see them, you have to use a holo background and not full black ones. You would have to find an dark gray image or something like an inverted app but isn't full black which is a good thing for me I guess. The good thing is that they don't appear on bright colors (red,blue,white,etc) which I personally couldn't see it. A holo background or gray image is when I can see it the most. When I put a black image, its fully black with no stuck pixels in sight. So that could mean they still work and turn on and off fine. So I'm thinking it's just stuck when displaying colors other than black.
I've kept my brightness 1/4 bright all the time, only used it for watching videos and browsing the web mostly. It's been one year since I bought this and I personally don't mind it. This is what I've seen so far
Edit: using a screen filter app to darken the screen on an holo image made it show the most so I can see. This lowest stock brightness doesn't seem to show a lot unless you get close to the screen.

A couple of weeks ago a guy bought an demo 10.5" and it had an perfect Samsung logo and stripe burned almost across the entire center of the display, the worst i have ever see.
He was asking would burning in the inverted image reduce the burn-in, I found the exact Samsung wallpaper responsible and inverted it for him, but i never heard anymore, it really needed an new screen.

[Q] Want to buy nexus 6, are there still screen issues persisting?

Please help. I am planning to buy nexus 6. I have read a lot about nexus 6 display issues like burn in issues , uneven color, grey lines and lower half of screen freezing. Some say these are present in all devices to variable extent and in most exist in mild form.
Should i get nexus 6 ? does these screen issues still exist?
Else i will buy Galaxy s6

I've had mine since November 2014 and I have none of those issues.
Smooth sailing here
I keep it adaptive 66% brightness and its all good no burn-in that I can see I have noticed some specific apps like chrome cause a weird freeze on the right screen half happens maybe once a month with no pattern (a quick screen off/on fixes it could possibly be a custom kernel thing). Only other thing I'd say is the screen has a very warm color palette by default, I use code blue with kcal 237, 235, 255 to make a cooler feel, there's a thread about it somewhere. I've had mine since February.

The Galaxy S6 has lots more software issues then the N6 atm and besides that i have never personaly had this screen issue. The N6 is a great phone especialy now it is beeing discounted here and there (US and UK).
Been rocking N6 for last 1 month and i am loving it. No issues at all. Like u i was also very concerned to put into huge sum of money into N6 purchase after reading soooooo many discouraging videos and reviews and comments.
But i am using it as my daily driver for like 1 month now and i haven't seen any issue related to screen, battery, or even software. 5.1.1 is very stable.
I keep the adaptive brightness on and brightness level at 50% and i get 4 - 4.5 hours SOT with everything on...including google now, location history, location reporting high accuracy.
No screen burn, no battery swelling, no battery life issues, no screen freezes, bt yes i'll admit the screen colour is more on a warmer side.
I got a Nexus 6 from Google Play and a friend got one from Motorola in June 2015. Both have screen issues, one have vertical banding noticeable on gray or dark backgrounds, the other has a yellow tint and very uneven backlighting. I'm not sure if most have these issues and simply aren't bothered or what. Not sure what to do at this point.
Flawless here
No issues with mine ....
mine works fine never had any of the issues above
No issues for me.

There's no backlighting.
What I meant to say is that strips of the screen are brighter or darker than the rest of the screen and it looks blotchy. If I hadn't viewed a solid gray screen, I might not have noticed but this doesn't make me happy, especially knowing that Android M has a dark theme with lots of grays.
I've had my white 64gb from Motorola since March. Had it replaced once already for the screen tearing issue when running a custom dpi. The replacement I got a month ago does the same. Will be calling again soon

I got a nexus 6 at ATT through the next program a couple months ago. It had banding on the right side of the screen right out of the box. It was pretty discouraging. I took it back and got it swapped for another unit and honestly couldn't be happier. The n6 is an amazing phone.

Screen tearing or half black?
Issues relating to custom DPI happen on them all.
I received mine on 6/18, no issues other than a pink hue at low brightness (with adaptive brightness turned on) which seems to be software based.

Half black, and half freeze, which I've seen be referred to as screen tearing in just about all the posts I could find on it. Funny thing is on every kernel or ROM thread ice asked about it I've been told it does not happen on all of them. Seems many have had their phones replaced and had no issues in the replacement and that has led to people believing it's a hardware issue. Only other explanation I had seen was something about Franco saying it's a possible display driver issue. Sucks that I can't use Franco kernel at AOL because it becomes horrible

The tearing, which by that I mean freezing definitely seems to be a graphics card issue. The half-black if you change the DPI and rotate clockwise so buttons are on the bottom, afaik happens to them all. I think this is related to the GPU to, though I don';t think that is hardware issue. The tearing issue seems to manifest more when the device is warm/hot

The tearing is a graphics card software or hardware issue? I love this phone, but it's getting very frustrating. Especially since my RMA prices with Motorola turned out to be a series of clusterf*cks.
I'm running Chroma right now and with the included Franco it's unusable in both my phones at a lower dpi. Half screen freezes left and right within seconds of starting up. The reasons I initially believed it was software was that it only seems to happen in certain apps. Specifically ones that required a lot of scrolling, like XDA, Facebook, and chrome. But no one else in the thread seems to have the issue
The half black screen I figured had to be software because the soft buttons are still on the screen.
I just wish there was a solid answer so I could stop guessing

I've never had the tearing issue and not everyone has that one. The guys who have had an RMA have generally said that it had stopped the issue happening. Im not sure that has any link to DPI either. My suspician based on not really any evidence at all is that it is hardware related, since some have it and some do not.
The half black is definitely linked to DPI and there is no fix to that that I am aware. I just turn that rotation mode off so I can only go anti-clockwise.

The weird thing with me with the tearing is it only happens in certain situations and has been consistent across both devices I had. Certain kernels I get it, other ones I do not. Franco has been unusable for me on both. It has only happened at lower dpi. Never on stock. Send to be less frequent with interactive governors than ondemand or conservative
