[Q] Display fault. Hardware/software? - Galaxy S II General

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!

Dead/Bright pixels problem?

Hi guys.
I'm interested to know whether Hero sets from overseas are experiencing this problem. apparently, users who bought it in Singapore (where i live) have this problem, and it's pretty widespread.
just curious to see if the problem is limited to Singapore or it affects other territories as well
Hi. I have T-mobile G2 in UK and I also have dead Pixels. As Fact I know people have this problem and It's not rare. I didn't send it back cos I Can live with it but i know people who sent it few times and still have received with dead pixels. Sad but its true.
i got 1 tiny little bright one.
annoying at first but i forgot about it after a couple of days. theres more important things in life to worry about. besides, most bright pixels right themselves after a few days/months...
i'd live with one or two dead pixels myself, but people have reported up to 8 dead/bright pixels, so it's kinda worrying
I do have around 8-10 dead? pixels but you can't notice them. One of them is bright enough to notice on black backgrounds and menus, but you hardly notice the other ones.
It's kind of weird though, they all appeared after 1-2 days of usage.
I have 1 bright pixel after 2 weeks using. The shop don't change the device with one dead pixel. Sad. In Hungary/Europe.
2 bright spots here. they are really tiny tho and i only ever notice it while booting which is not that often. no dead/stuck pixels on my hero *yay*
stuck = bright
sounds like someone needs to create an app for Android, like the apps to fix bright pixels on normal computer monitors, where u select the region on the monitor where the bright pixel is and the app constanly flashes different colors...sometimes rectifies bright pixels after a couple of hours.
i believe some of the bright pixels might well be enclosed dust ...

i have to say that i don't have ONE dead pixel on my screen. It's really great. My past device (xda orbit 2) also had another problem: dust gathering beneath the display. i don't have any issues with the build quality with my htc hero and i'm really picky too.
it's an unbranded german white HTC Hero.

If it was dust though, wouldn't we notice an increasing number of bright pixels as the days pass?

i haven't looked into this myself ... just quoting other people here.
the people in the other thread seem to have come to the conclusion it is dust enclosed in the assembly process. the seal around the displey seems to be quite good ... so no new specks of dust over time

Me too, I have 8 - 10 dead pixels but it hardly to notice them! you will notice them when boot the device.

i am not sure if mine is considered dead pixels but when the device boots up, the upper right side seems to be brighter than the rest of the screen (light shining out more from there)
however, once the device is booted up, it is no longer noticeable, maybe becoz the screen is not totally black. the only way thus far i can replicate this is to shutdown and boot it up.
does anyone have this issue?
Yeah, I also got the brighter screen in the upper part of it during boot, I think it is because of the backlight to the device so I don't think it's you really need to worry about.
But concerning the topic, I also experience dead/bright pixels during the boot up, around 3-4. I didn't even notice them during boot before I saw this thread and decided to take a closer look, not that a huge problem for me as i can only see them during the boot, and neither got I the patience to wait for it when it is at service.
first day with my hero from orange france and 1 dead black pixell !! RRRRRR

How often is the "dead pixels" problem?

Hi guys!
I'd like ask all of you how often is this problem in Hero series?
I bought one a month ago and it has some stucked pixels, but I heard that the chance of getting even worse phone is bigger, so I decided to keep this one, because these dots are practically invisible during the common work with the phone.
I can see one or two if I set the brightness level to full, but thats my second question- how many of you use brightness on full or you do prefere to keep it on automatic? I discovered that on manual setting the phone loses light sensor function, am I right?
A couple of dead pixels here too... But can only really see them when I boot, so it's ok. So far...
p.s. I use half of the brightness. Full brightness i s great to show off but sucks up too much battery!!!
A few can been on boot on my phone too. Not really a big deal though.
From all opinions I got (plus from the other forums)- here is the statistics:
38 people don't have any/ 34 do have this issue...
Not good for HTC...
Hardly an exhaustive sample! Plus, you're more likely to get "positives" based on the thread title, because it's far more likely that people with dead pixels will read it!
That being said, it is *very* common, and not just on the Hero. You don't need to google for long to find that the iPhone has similar issues.
Regards,
Dave
Yes, you are right, but still.. even those people with this problem are enough evidence that it's something wrong with the quality control. I am not saying that it's happened only to HTC Hero, but it's a big problem in general and I don't agree to give 400+ boxes for getting stucked/dead/bright and so on pixels. This is just kind of thinking, and when the manufactures realize that it would be much painless for us- the clients. It's all about the quality control- in general- monitors, TV's, cameras, laptops...esspecially when the items go above define price. You get it what I mean..there is no room for joking with the clients. Ok, I am gonna change the device- once, twice, three times, but where goes the starting point that has made me convince to buy exactly this model? Nowhere..the same with Iphone, Sony Ericsson, Nokia... We are living in 21st century and the perfection is tide connected with this time..or at least that's my point of view...
The issue is that the yield of 100% "perfect" LCD displays is actually quite low. As this article states (under Quality Control) it is economically prohibitive to throw away otherwise perfectly good LCD panels for the sake of a few dead pixels.
Unfortunately, as it currently stands with LCD manufacturing methods, for us all to be *guaranteed* screens free of any dead pixels, we'd probably have to pay an awful lot more for our devices since many screens would end up having to be thrown away.
Regards,
Dave
Ive got none however I do have a little light leak in the top right of the display
I have 2. But I dont think they're dead pixels but dust that's visible on the black background with booting. Cannot see them at all with normal use.
If they were completely dead pixels it might have been more nasty.
It's in the nature of fabricating lcd displays. And has been a problem for a long time. Anyway, with my Hero I can't be bothered about it.
If you have stuck pixels, try JScreenFix. Its free from the Market. worked for me!
i had alot on my first device.. i traded it in.. this one has 2.. they only show up during booting.. so i guess its not a big deal
I've had a couple of Heros by now:
1. very visible dead pixel (centered in market search field) -> returned
2. Really large gap on top side of display glass -> returned
3. happy until after 3 months suddenly loads of dust appeared below display glass -> returned
4. dead pixel in prominent place -> returned
5. I'm very happy again. hope that dust will stay away from underneath the display glass.
So, my personal record so far: 4/5 Heros are flawed (3/5 Heros on arrival).
That's really sad as it is such a great phone otherwise.
I've posted about this before, if they appear as bright white specks when brightness is up full (such as during the boot animation) then it's dust, not dead or stuck pixels. You can open the phone up and remove them. I've seen it on multiple handsets, turned out to be dust every time.

In my case the first pixel was permanently green, while it was a red pixel in the second case, definately not dust. (I think these are correctly called hot pixels, not dead ones.)
i hab a dead pixel on the first day after i bought it. But i went to the T-Mobile shop immediatly and they changed my hero with a new one without any problems! With my "second" Hero i dont have any Problems till now. Seems like there are 2 generations of displays!
*edit*
my dead pixel was near the upper left corner and it was totally white. actually you could only see it if the rest of the screen was red or black. but as it was a mistake i changed my hero anyway!

Week old nexus one, already dead pixels.

Well I received my nexus one about a week ago and I absolutely love everything about it...
Unfortunately I've just noticed two dead pixels on the screen. One top left and the other bottom right. Both about an inch in from the screens edge.
I've seen a lot of posts of people complaining about clicking edges and dust under their screens but I'm pretty sure this is not dust. The specks look identical to each other and are tiny in size. They are mainly visible on light/white backgrounds.
Unfortunately I live far away from any of the Google supported countries so doing any kind of exchange is going to be really difficult :-(
Anyone seen similar issues? Any suggestions?
There's a coupla apps on the market to check for dead pixels.
All they do is flash up white, black, red, green, blue so you can see what pixel is stuck. It might be worth trying one of those just to make sure they are actually dead pixels.
If they were working before, they might just be stuck pixels, and alot of toggling between colours may unstick them.

But if it was a stuck pixel then you would see it lighting up on dark backgrounds but these are only noticeable on white or bright backgrounds.
BTW I have already tried the market apparently and no joy.
Has no one else been noticing these?
I had one stuck pixel that appeared a couple days after i got my phone
but i fixed it and it came back like 5 times.
But knock on wood its been 4 weeks and it hasn't come back.
Mine was weird it would only show on the lock screen and it was very random but once i swiped to unlocked it went away so it wasn't that bad.
If i were you I would return it especially were its two pixels and software isnt fixing it.

OLED have very deep blacks so its hard to tell if its stuck on black or if it is dead
...anyhow if you cant fix it you should return it.
Man returning it is a such a mission as it was bought in Singapore and I'm not even there any more...
I suppose I could find a way to send it back there and then from there back to the US.... heh. The problem is that I only received the handset about a week ago so if these kinds of problems have been reported since the launch whaat says the replacement wont have the exact same issue? Which would then be a massive waste of time and money ;(
Thats the problem i even set up an RMA to return mine but had a gut feeling i would regret it. So i canceled my RMA and prayed the pixel would eventually not stick anymore.
I didn't want to take a chance of getting a referb phone with other issues.
I feel your pain EVERY device that I get now days that has a LCD screen ALWAYS has at least one dead pixel. But to my surprise my Nexus One is 100% fine .

New phone, weird screen

Hey guys,
I just received a replacement phone from Bell, so now I happen to have two Galaxy S running in front of me. My old phone, for some random reason doesn't have the same colors as my new one.
The old phone, displays white really nicely, whereas the new one, it's more "beige-ish"... Overall the screen colors of the new phone are "warmer" and the old one has more realistic colors. Darker blacks and whites that are really bright.
I don't get it... Is the new phone defective?! Does it need break-in?
Thanks
Same Problem
Dude I got my old bricked phone replaced around a week ago and this new one's screen, like you said, has beige-ish or yellowish coloring whenever I put the brightness down below 20%. My old one was perfect, it showed the whites perfectly. What are you planning on doing? I think im going to take it in to the store. Did you find out the reason for it or take it in yourself to the store?
You guys should post the manufacture dates for your old and new phones. I got a new 9000M after my internal SD died but I never had both phones at the same time. As far as I can tell my new phone's display is just as good (maybe slightly better) than the old one. They were both 10.08 dates.
From what I have heard, a new AMOLED should be slightly blueish because the blue sub-pixels get weaker before the others.
My old one is 10.08 and the new one is 10.11. Old one's screen was perfect..but i dont know whats wrong with this one..its just yellow when the brightness setting is low..
Same here, bought my mother's captivate(not from replacement) and its screen seemed yellowish and darker than mine. However touch button backlight is much brighter than mine.

Any solution for this???
Sorry I have to say this, but it is absolutely normal. Had 2 sgs back in june. One ABSOLUTELY white and great screen (but also a dead pixel)and the other more as described here. Also the warm color is best be seen in an angel of normal use. Annoying, but you get used to it.

So Crypta, will this be looked upon as a defect. Could I possibly take it back to Bell store for a replacement. I cannot get used to this..its pretty bad, the yellow coloring i mean.
I think the speedmod kernel has colour adjustments made. Check it out in the Dev forum
Sent from my GT-I9000m
Kewjoe, could you plz tell me the step by step process of getting my phone to your phone's level. I mean Darky's rom..speed mod etc. Our phones (bell i9000) are extremely fragile and you know that. I wanted to get darky's on it but i dint want to brick it. Also, if i do mod darky's but somehow or another my phone needs repair and I need to take it back to bell, would I be able to bring my phone back to bone stock (bell jl2) conditon? If yes, how is it done? Thank you
Can't say if it is rated as flaw. Kept mine, as it is only a great difference in comparison. Saw 4 sgs screens - all different from blueish to pretty warm. There seem to be a great variation within production range.
sent from my cobra mk3 by a thargoid pigeon
This is normal in the process of screen, that does not come from the same production line.
Took mine in to bell store couple of days back and they shipped it for repair/replacement. They compared my screen to the phone on display in store and even they said mine was really washed out. I also had a loose battery problem so they mentioned that on the repair sheet as well. Hopefully I get it(or a replacement) back soon. They said 10 days..I'll let you know once I get it back.
is it still SAMOLED, does it still have DEEP Blacks? maybe they changed it to SLCD? i hope not!
Yea its still S-Amoled but it was just yellowy so I had to take it back. I dont think they would change it to slcd..lets see.
Chk this out, I think it could be software problem but I flashed many roms and it hasn't seemed to bring it back to normal so I sent it in.

Have you tried to Galaxy Tuner? It's available in the market, you can change the color settings with it.
I Swyped this on my Galaxy S
Different manufacturing batches ==>Different products. It may happen. But if there is too much difference in colors as you said it is a manufacturing defect.

half of the screen has pink shading :(

As always, every samsung device I have owned except note 2 has screen issues. Im starting to hate this amoled tech. I had 3 s4's and everyone of them has this pink shade in some part of the screen. Now this note 3 has the same issue actually its worse. I think I need to get rid of this and buy a phone with lcd screen.
Anyone noticing the same issue or am I getting realy bad luck?

get your phone exchange or refunded asap!
it sound more like a defect than a feature.
LCD also has issues.
Mine had a cream tint over 2/3 of the screen, which was not to obvious until browsing certain forums, where you'd scroll a message up and it would noticeably change color.
I took mine back to the store for exchange, and despite showing them what looked obvious to my eyes, they just couldn't apparently see it... Luckily, they where kind enough to order a new one and exchange it anyway, so will see how the new one does on Tuesday.
Some people are blind to such things, my One X had the yellow spots, so sent that in, and the replacement was much better, to they point I could easily live with it.. My two nexus 7s are fine, and every other Samsung device in their store looked good enough that I'd be happy, so I feel justified in getting an exchange...
I sold mine and bought another, lost about 50$ . Newer one has yellow hue or tint in right bottom cornor in whites and grays. I deserve this I guess, I didnt learn my lesson.
