[Q] Display fault. Hardware/software?

So i recieved my Galaxy s2 the other day, as a replacement for my HTC HD2 which was in for a repair with a broken screen - apparently it was 'unecconomical' to repair - but i certainly wasnt complaining!
Awesome phone, had it for two days, rooted it fine using Odin and superoneclick - fantastic tool..
After rooting i re-flashed with stock kernel again.
All was absolutely fine, i was using my phone without problems until a few hours later (yesterday evening) when after putting it down for five minutes and picking it up again, there was a pixel wide horizontal line running across the screen.
They are not dead or stuck pixels, as they change colour with the background- they just appear extremely brightly, so stand out from the rest of the display.
No amount of adjusting has resolved this, rebooting/hard reset etc. the line remains prominently running from the right side, and slowly fading to the left.
Ive searched online but cant see any issues with screens like this, just dead pixel lines and stuck pixels.
If anyone may have an idea on whether this could be software related problem or hardware related would be great to know your thoughts.
Cheers, Alex

I would be taking it straight back . I got a couple of sgs2 handsets back in may when they were 1st released and i had numerous screen issues. i got one a few days ago an my friend got one yesterday and the screens are pretty much bang on (tiny tiny yellow tint if you go looking for it)
No lines , no dead pixels , beautifull screens even with the slight yellow tint
I hated my 1st screens so there are defo some bad ones knocking about and some that are literally 10x nicer to look at
Like i say take it back buddy
Good luck with it and let us know how you got on
Also pictures of the problem could be interesting

Yep I definitely will...
Just whether to un-root and reset flash count first or not - probs a good idea im thinking.
Aside from that i agree its a lovely display- ive heard about the yellow tint but noticed it on mine.
Will try and get a pic up before it goes back..
Cheers for the input!

2.3.5 and Yellow Tint on Galaxy S2, Need Feedback!

Users that have installed the Official 2.3.4/2.3.5 on their S2's, has the yellow tint alleviated in any way? Provide your responses on this thread!
I have asked this same question on other threads (i.e. Display problem/yellowish left side) but looks like this question is off-topic for those threads and I am not even getting the appropriate response.
I am currently running 2.3.3 (unrooted) and the yellow tint is still there. Apparently, the yellow is tint is a drawback of SAMOLED+. Many have claimed that by installing later firmware, the yellow virtually disappears. I need some assurance here because this tint is seriously below my expectations for such a premium device. I'm sure most of you are also in the same dilemma.

i cant say for 2.3.5 because i havent flashed it (i'm on Cognition 1.5.1) but i CAN say that i DID have the yellowish left side but what FIXED it for me was the Voodoo Screen Dev app by supercurio
i think its actually listed on the market as "Screen Tuning dev channel"
there's a thread in the dev section somewhere
but once i installed this app and changed between the "native' profile and "Samsung" profile, the yellowish tint disappeared for me
100% sure i HAD the yellow tint and im 100% sure its gone
Easiest way for me to see it was pulling down the notification bar - or on any grey backgrounds
But im pretty sure you need to use a custom kernal that supports the profile settings. I'm using Ninphetamine 2.1.3 but i remember installing SpeedMOD kernal and i saw the yellow tint again
THIS IS JUST MY OBSERVATIONS
im not entirely sure if this works for everyone , but it did for me
so good luck
recap:
I'm running
ROM: Cognition 1.5.1 (2.3.4)
Kernal: Ninphetamine 2.1.3
App: "Screen Tuning dev channel" on "Samsung" profile setting
Left side yellow tint is gone

Used to be there on KH4, On 2.3.5 it has disappeared.

Interesting,
I don't want to void my warranty, is going by the above safe?
Also, I do see a slight whitish discoloration on the top right display. When applying the yellow-fix is the whole whole screen calibrated or is it only the area on the left where majority are facing this yellow-tint issue?
Thanks again.

Why don't you update your phone through Kies like I've told you in the previous thread? Like I said, the '2.3.4' update fixes the yellow tint

No yellow tint on 2.3.3 2.3.4 2.3.5

No yellow tint on 2.3.4 2.3.5 for me

No yellow tint in all the roms that I tested.

mine no yellow tint so far on Leo2.7, but yes, camera pink spot still there..

I had this problem, fixed by going into display settings -> screen mode -> change from movie to standard.

2.3.4 is not available in my region yet, and looks like 2.3.5 will be available directly when released according the company
Those that have unofficially flashed into different ROMs must have had yellow tint before. Yellow tint exists on all devices which are shipped out from samsungs factory. if you have not rooted and loaded an unofficial rom then yellow most likely exists. some devices display the yellow very prominently whereas others don't because that area is overlayed with darker hues.
i have a funny feeling the company is actively working on this and making sure it doesn't happen to their successive displays

None here ^_^..... Very fast!!!! 4000 quadrant wooohh!

2.3.4 removes yellow tint as well as as 2.3.5.

Sorry but this is absolute rubbish. I have not, and many others have not, got or had yellow tint. People can bang on all they like about it, but just because you have it does not mean I have. I HAVEN'T. Deal with it, because it's not going to change. Yours is faulty. END OF.

If that's the case, MAY I REQUEST you to POST A PICTURE of your phone with the notifications area or gray background displayed. AFAIK, only one user managed to prove he did not have an faked up display. The rest of the owners that have claimed they did not have yellow tint FAILED to post up a snapshot proving themselves. I don't want to sound intrusive or anything, but this is an issue that encourages every XDA user that owns an S2 to look into. This is not a joke. Thank you.
Apparently, all of you are claiming no yellow tint, may I please request to those that can--upload a picture displaying your notifications area / grey background on your phone with (10%, 20%, 50%, and 100% brightness). thanks

No we won't and why should we, none of us have had yellow tint. You got what is possibly a faulty phone contact your nearest samsung sc if you are still having problems.

well i had yellow tint on stock india firmware 2.3.3 but then on 2.3.4 (KH3) it was gone n its not present on 2.3.5 KI3 also

There's a large handful of folks having this issue; a lot "were" having yellow tint (check out this thread! http://forum.xda-developers.com/showthread.php?t=1079444) until they updated their firmware to 2.3.4/5.
The issue doesn't lie in the hardware of my phone; it is more because of the software used to to calibrate the screens. the algorithms are not set right for particular batches at samsung's number of factories.
i went through three replacements and first two were not severely yellow, as a matter of fact, i thought my second to last replacement was perfect until the next day, there was a vertical line that wouldn't go away, coincidentally that vertical line was in the same area where many reported seeing yellow tint.
btw, asking to take a picture was a small request, this is a community, thank you

In the pics it seems as if they are yellow stains on the screen. Are they permanently fixed at one place? It seems like a hardware problem...
If i'm wrong about yellow stains and if the whole screen is yellowish then you can try flashing CM and use render effects, there's an effect which adds a bit blue to yellow colours so it gives a cool effect which is quite an eye candy. Try that.

[Q] Screen red/burgundy tint on blacks in darkness?

Hi,
Samsung S4 owners please help. Just received mine and everything looks good, however the screen has a red/burgundy tint on blacks in total darkness.
For testing I closed the camera lens and took picture so it's totally black, when you look at the picture in the dark it's not black and has red colos in it comparing to my Note ii and LG Optimus G.
If you have the same problem please post, so I can return it in two week period or switch for HTC ONE.
Thanks,

My screen is 100% black on darks. It looks like its completely off.

I have this too, it's not the OS as the screen was very very dark red when I was soft-bricked.

Confirming
Just back from 2 AT&T stores to check if demo S4 has the same problem, and confirming YES the blacks in total darkness is more like super dark dark red not 100% black.
The AT&T rep confirmed and said "If you don't like it, return it".
Also I found topic that covers this problem regarding red subpixels being active when displaying black , but the international version is fixed after firmware update.
So I think only US AT&T models affected with no fix for now.

Another thing I found is that if I scroll really fast on a black background there's a reddish haze on the screen.
Turn your brightness all the way down, go into a dark room, open settings, and scroll really fast up and down.
Does this happen to everyone else?

I Have the Sprint model and also experience this problem. There are several issues I have with this phone. Lag, software glitches, keyboard issues etc. And these occur on every S4 I have used which is several, none Exynos versions though. They rushed the release is what I think. They should have fixed the issues being compained about before release.

There is a long thread in the international S4 forum discussing this. There are two different screen problems, either red pixels are on when displaying blacks, or you get smearing on greys/purples over blacks. Samsung just released a firmware updste for the intrnational version that gets rid of the red pixels for those who had that issue, but it makes their screen smear. So no everyone has the smearing problem with tbe international version. Hopefully they can address the smearing problem with firmware soon. I can imagine some games being affected pretty badly by this issue.

Samsung S4 AT&T Version Red subpixels on black stay on.
See attached sample image. Easy to see in total darkness when brightness all the way down, red pixels visible on any black, picture, menu, web etc.. except boot logo.
The image made in total darkness, for black sample opened 100% black background.

I also have the red subpixels on my sprint sgs4

I had this on my first S4. My GF didn't on hers. I took it back to the store and they looked at me like I was crazy (didn't argue that fact).
Rep took it to the back to show manager and pull another phone and he told me that this was common enough that they got an email about it from HQ.
New unit didn't have the problem.
Not only are blacks with a redish tint, but another way to tell if the screen has this problem is press the menu button. Then, it is easier to tell a good screen vs a messed up screen because they are clearly a different color. Easier to show them that instead of minimum brightness, in a dark room, you can see it I swear kind of argument.
I wish I would have taken a pic to post the differences.

Thanks for reply,
So you just went to store and replaced bad one for good one? So maybe it's a first ones with this problem? I visited 2 different stores and demo units red as well, they said that all devices they have in stock is the same shipment 60 or so units. Will try next week.
Thanks again.

Yea, just head over to AT&T and swap it out. A display issue such as this is very rarely addressed in firmware and has to be replaced.
I replaced my unit yesterday no questions asked(kinda) as they're very aware of the myriad of issues some early devices have. Just don't use too much tech jargon like "pixels" "true black" "contrast ratio" etc. or you might get blank stares as I did lol. Good luck.

I have the T-Mobile version and have this also. I noticed it when I first turned it on. I had an S3 before so I know how black the AMOLED screens can get. I don't mind much since it's just when it's displaying blacks and I haven't seen it much except for boots. I think I have the smearing too but I just look at it as motion blur :silly:

Try turning off the auto brightness. My S4 does the same thing only when auto brightness is on.

does this happen on all models, random models, or only white/black models?
I'm curious to see if this is a potential side-effect of that semi-transparent digitizer (like the notification screen-glow thing that was mention in other threads).

[Q] Note 4 (910F) off white / yellow tint display

Hi , my name is Stefan and i am new on the forum ...
Regarding yellow tint display if somebody have an advice ,anything to solve this.
I must confess that although I have changed three screens, I have the same problem ...the display is not trully white .
The comparison is made in the same conditions : both phones are on 5.0.1 Lollipop,brightness is on maximum,adaptive mode display,auto adjust screen tone.
If somebody can tell me what is the problem , please because i don't understand why and how is possible ?
Screens can be recognized by a code, a serial number or manufacturer / supplier or is there something to differentiate between them ? From where to buy or achieve a display that have non tint yellow screen ?
Any advice is welcome because here i think is my last chance to find out what is it about...
Thank you

Have you tried to remove screen protector, just to check that its not that?

Yes , sure that i removed also screen protectoon but is the same yellow tint dispay !

And another important aspect also is , if you look carefully to my pictures beside that my dispalay has yellow tint , the colours are less vivid

Did u change the display settings

if you have the cinema mode for display selected then its because of that

You can't make anything to fix it. Mine screen is like yours. Also change my phone 3 times and always the screen is the same.
I've white phone like you. I think the problem is with white phone manufactured during 2015. I think 2014 phones doesn't have this problem.
Cheers.

No way ! My phone is always on adaptive display screen mode and auto adjust screen tone
These are the most recommended settings for Note 4, so far i know ...

I never thought at this ...what are you saying is incredible for me , this don't solve the problem but i must confess that i' m really very shocked !!! And yes , indeed you are right ! I took an app, from Play Store called Phone Info *Samsung* and manufacturing date is 2015.02.03 ,made in Vietnam
If you are right is something unbelievable !!!

So for me it's easy to find out if you're right about what you said, because tomorrow I will go and i will check if all phones that have white screens compared with my phone are manufactured in 2014.
And after that, I'll post the results here !

As i promised i'm back with the results after i checked today 4 phones that have white screens from different suppliers and situation is as follows :
1.From 2 different Orange stores i checked 2 phones both on black colour ( they sell only black colour) , first one SM-910F(snapdragon variant) was manufactured on 2014.10.08/made in Vietnam and the second SM-910X(demo unit phone) don' t appear any date of manufacturing just made in Vietnam.
2.From Media Galaxy store i checked 1 phone SM-910C (octacore exynos variant) white colour and this was manufactured on 2015.01.19/ made in Vietnam.
3.From official Samsung store i checked SM-910X (demo unit phone) ,don't appear any date of manufacturing just made in Vietnam.
While I was in the official Samsung store, I met someone, who had bought a Note 4 from same supplier as me and the phone was the same colour white , same model (SM-910F) but this person told me that bought the phone in 2014 and we checked together with the Phon Info app and yes indeed the phone was manufactured in 2014 / made in Vietnam but this phone don't have white screen !!! but the phone screen although it was manufactured in 2014, the screen was more yellow than my phone which is made in 2015 !!!
And another thing would be that my phone which is compared in pictures with the phone screen from Media Galaxy store, but it is also manufactured in 2015 , the same as mine,this phone has a white screen and not a yellow screen like my phone .
So the final conclusion :
is NOT TRUE that all the Samsung Note 4 phones manufactured until year 2015 have white screens and the phones manufactured after year 2014 have a off white/ tint yellow screen !!!

Ok, It was a guess, because in my country almost Note from 2015 have this yellow screen, also new Galaxy S6 have too.
It's true that if you search you can find a good screen but I think 75% of probability is to find bad screen.
Cheers.

I got my note 4 shortly after it was released in Oct 2014. The past month I noticed only the upper half of my screen has a yellow tint to it. I've already tried display settings. Also tried resetting the phone and clearing system cache. It isn't the screen protector. I've investigated many forums and took every advice I can find and still the upper half of my screen has a yellow tint. I see a ton of people have this issue. This phone is supposed to be good for video and video editing along with photography Kind of hard to determine a good picture if half the screen is yellow. I am sure Samsung is aware of this issue but why have they not resolved it? Seems like a recall would have been made on the phones and replacements sent out. Paid over $800 for this phone, I could have kept my old Note 2 and invested in a good camera instead. This really needs to get fixed. If Samsung customer service is going to be this bad I will go with HTC or Iphone.

Try to set it like that!!!
