Pixel that is really bright and white - Galaxy Tab 4 Q&A, Help & Troubleshooting

It has been 8 months since I got the tablet and my Knox is tripped. I do believe that its a dead pixel and wondering if I can still get it replaced or not. It didn't have this dead pixel until now and it is really irritating me.. This is my first time having a Samsung device so I don't know what exactly Knox is or if my warranty is still valid, assuming its a standard 1 year warranty. Please somebody help me. I really need to know if I can get it replaced or not.

I should also mention that it is only noticeable when I am on a white or bright colored screen. It is t seen on black or any other darkish colors.

Nobody can tell me what to do about it?

Can someone please help me?

Stuck Pixel Desire HD

Hello, i'm sorry for create duplicate thread from http://forum.xda-developers.com/showthread.php?t=1093995 because i did't get any answer, so i decided to open new thread at this subforum, because many ppl look at it
few weeks ago [3 may 2011] i bought a new desire HD
and today, i realized there's a stuck pixel at the top right panel near the clock, the panel gray and the stuck pixel just colour almost same, take time and focus to realize it.
i create a new thread because all other threads of the stuck pixel didn't give me any solution
and this stuck pixel not just stuck in 1 colour
but,
when the screen is white, the pixel is red
when screen blue, its blue [dissapear]
when screen light purple, its light purple
when screen black, its black
when screen green, its blue
idk if the pixel really gone when its blue or purple, but my eyes are normal i guess..
JscreenFix tested, 1 hour, no work
tapping, scrubing, massage method, no work
is there any other method that you recommend?
i didn't root the phone yet because it still in Warranty, and i guess if i bring it to HTC Care, i won't get a new unit, but a new lcd, and the mechanic sure open the phone and broke the void sticker..
any suggestion?
If you have tried all the above I would phone HTC and try and get it replaced...
Good luck as some people have problems replacing phones with dead/stuck pixels as they are allowed a certain percentage of dead/stuck before its deemed a fault

The HTC didn't want to replace it, but i contact the shop where i buy and ask them for replacement, but still is there any other method that someone had test it and work?
I'm not suggesting this, do it at your own risk, don't blame me if you brake anything!!!
There is a way of "unstucking" the pixel by pressing hard on your screen(so I've heard, never had a dead pixel in my life=>never tried it). It looks like that your pixel isn't actually "dead"(it would only shine in one color(white) or wouldn't shine(black) if it was), but rather "stuck"(again, so I've heard, and didn't do any research about it, how and why is this happening, so there's a big chance I'm wrong).
If they won't replace your phone, and you don't really want to try exotic stuff that might break your phone(like pressing hard on the screen/dissassembling the phone and poking the screen from behind with the screwdriver/yelling loud at it), there isn't really anything that you can do about it, except get used to it...
I've had a stuck pixel on my Desire HD since 4 days after i purchased it, which was at the beginning of December. At the time, i tried everything i could to fix it but nothing worked. So now i just learned to live with it.
Btw, i really recommend to not try push/massage on the screen because the glass on the DHD does not flex. If you apply enough pressure you could shatter the glass (considering it's not gorilla glass).
So if JScreenFix doesnt do anything then im afraid nothing can really be done, unless you decide to disassemble the phone yourself (i dont recommend), or brake your phone purposely so HTC will replace it

It takes 3 dead pixels to replace it with a new one, here were I live. I have one on my DHD, but it's in the down right corner, can't even see it, noticed it by accident when i was watching a video that was cropped so it had alot of black around it.
Otherwise, don't see it-don't care
I've even had a dead pixel on my Philips monitor, for 1 year, and then it just dissapeared. And it was a red ugly one, right in the middle of the screen, very annoying.
I've had a stuck pixel for some time now. It's bright red and in the middle of the screen, i just lived it. I barely notice it. Only when i look for it do i find it. I'm tempted to say 2.3 fixed the problem for me but it could just be that i changed my wallpaper from the live sense one to a black one.

[Q] Scren problems - dead (?) and overheating pixels

Hello!
Week ago i sold S3 and bought N4. I'm happy right now, especially from screen (PenTile < IPS ) but...
When turn on white image and look from left side i see two, dark stripes.
Also i have 4 overheated (super bright) pixels, and (I'm not sure here) some dead ones.
I don't know what to do. It's a good point to sent phone on warranty and exchange it to newest revision by the way? (RMA)
And yes... I have blue and orange tilt too.
I saturated photos for better look at my problem.
Bump. (can I?)
Aww thats bad luck...issues like yours are very rare... I suggest you RMA it mate... mostly i accuse people for RMA'ing devices without any good reason but your screen is in pretty bad condition...overheated pixels ? Nahh it seems more like the screen already came defective with some dead pixels included. I've got my Nexus 4 about 2 weeks ago aswell but mine neigher has any dead pixels nor any dark stripes...my tip is just RMA it to google and get a replacement.
Goodluck with it.
Respect
Thanks for advice, but I just realized, that I can't send my Nexus for exchange, because I'm from Poland, so I just have to give it on warranty. Shame.

Rendering black colors

So i been having the s5 for about 3 months now! Sudently on day my screen got a yellowish tint on it! And it was coming and going.... after a while! It went out but now the black color has a lot of noise on it! I've tried the free app screen adjuster and other paid ones that kinda resolve the issue but not quite as a white low density ghostly look stays in the screen. Trying stuff i rooted the device messing the knox counter so i pretty much voided my warranty any one here with this issue that has been able to resolve it????

Screen tinted blue and yellow

My screen just started to change color periodically, and it looks like the screen is tinted either blue or yellow and then it sometimes flickers back to normal. It's not a dark tint but it's definitely noticeable when it changes. I was wondering if anyone else has had this problem? I'm rooted and running one of the delayed Roms. Also I bought this phone from a friend about a month ago so I'm not really sure what kind of warranty is offered or even redeemable in my circumstance
EDIT: never mind im just dumb and didn't realize adaptive display makes the screen look stupid like that. But i am still curious as to the warranty question in case i have any future problems

Pixel turned to green color

Hi please i have a a5 2016 and i noticed few days ago a pixel turned to green . It is a dead pixel ? How i can fix it please reply im worried . It is rare in AMOLED screens ? Thanks
Hi! ..got the same problem, however I can see not only our pixels are dead, also thread stuck in spot..
Phone is new, after two months, in the center of the screen appeared one bright point. I don't know is it dead, hot, or stuck pixel.. It's green and max-bright. Especially annoying at night, while watching/reading with dimmed screen../
Any of repair apps (flashing/snowing) wont work, Odin also - maybe there is some framework, that could at least turn it off (or sth..)???
Did anyone else had that stubborn pixel on this ultra FHD 5,2" 1080/480dpi AMOLED screen?? Anyone can help??
- Did You managed with your green dot??
- Does one bad pixel qualify device to service repair?
Unfortunately you have to replace display. Both of you guys...
Guys, you have warranty if you haven't done any modifications to your phones. In this case, take your phones to your carriers or Samsung Stores and they'll repair/replace them without any question.
