Dead Pixel?

Anyone get a dead pixel on their Incredible? I noticed mine in the NANDROID screen when the screen was all black. Any way to fix this aside from an exchange?

I got one. Started almost right when i got it. I Dont know how to fix it.

I tried a program called Pixel Fixer v2 from the market. Didnt work. It allows you to set the background to all white or black to see the pixel and then it flashes colors in a limited radius to try and get it unstuck. Give it a shot it may work for you.

Only real way to fix a dead pixel are to hope it becomes un-stuck on its own or to try to gently massage it a little bit. You may just have to deal with the dead pixel though, they're not usually fixable.

Turns out mine isn't actually a dead pixel. Ass the underlying pixel on mine actually still works. My screen just has a little black dot under it.

yellow screen tint/spot FIX!

1) go to display settings and set sleep to never turn off and brightness to full
2) install 'dead pixel detect and fix' from market
3) open 'dead pixel detect and fix' select colors, custom then a nice bright yellow
4) once your screen is bright yellow put on charge and leave for the night
I'm unsure if this fixed my problem or just a coincidence that my screen got better over night anyway but I thought I would share to see if it helps anyone else.

It had been 2 days and is still good. I read up that a lot of one x's have the same problem, yellow smudges appears about 3 days after purchase but suppose to fade after about 2 weeks. So I don't think it will return this is just to speed things up a little.

I thought that it was due to hardware, but maybe not so much?

Well ill try to work on it for few days on full brightness, maybe it will reduce the glue grain, I noticed its on all one Xs they just vary in intensity

Sometimes pixels get stuck at a colour and flashing the area between different colours really fast can fix it.

Unfortunately my screen is yellow at the bottom and every pixel app I find has the menu bar there. What I did do though was leave chrome on the settings page and it did help to reduce it., however I've just been playing some fruit ninja. My phone got hot the touch screen stopped working correctly and the yellow is back worse than before

I am trying this now and will let it run overnight.
I currently have 2 yellow spots on the top of my screen. Hoping this will make them go away faster.

My yellow blobs was at the top of the screen, so the black menu bar at the bottom wasnt a concern for me. I am currently using tripndroids cm9 build that takes the black bar away and gives you full resolution use. Only attemp cm9 if your boot loader has allready been unlocked, so you can still replace your phone if things dont improve.
for anyone using cm9 they dont have the option to turn display sleep off completly, so i would recomend downloading an app callled 'screen on' that does the job from the market.

The yellow tint/spot isnt a hardware fault. It comes from poor manufacturing processing. If you squeeze hard on the edge of the screen for prolonged time, the yellow tint/spot appears. Once the pressure on the screen is normalized, the tint/spot will be gone. However, there is a chance that prolonged pressure will cause permanent damage, it is wise for you guys NOT to put your H1X into your jeans pocket!

That can be achieved by just clicking fix on the dead pixel app, when i attempted this for about 2 hours i never saw any changes as after just trying a constant yellow i instantly saw that my screen got brighter, whiter and the yellow smudges on top of my screen started to fade. I compare to my partners one x to check for improvements.

Any luck?

I do hope that this solution help you with that problem.. however there must be a reason why HTC help support keeping my HOX at their location , as far as I know they waiting for new battery as well as NEW LCD..according to that information must be smth wrong with LCD... (yellow dots of course)
So I need to switched back to my HP pre 3 for a while..

Hi i have the same problem with my HOX, my HOX is perfect except for the blue spot when i turn my screen brightness to full and use a black wallpaper you can see the blue spot, i dont know what i must to do because it is my second HOX and it took me 2 weeks to get a replacement unit from virgin if any body in here has experience with htc australia service centre please let me know thanks (i did try to use the app but no luck)

Alright -
I let it run for like 12 hours last night.
My yellow spots are about 75 percent gone!!!!
I am going to let it run again tonight and will give another update.
For those of you will yellow spots I would suggest giving this a shot. So far it seems to be working for me. Although I will keep an eye on it to see if it comes back or gets worse again.
Thanks!

any idea if this deals with the glue grain too?

I don't think the color really matters - what metters is that it is left alone AND getting warm.
I guess if you put a book on top of it while running a 3D game, 90% of the spots will be gone momentarily, but as soon as you start using it they will creep back because it is a lamination problem and not a screen problem...
And for those who claim their spots "disappeared" after a week - yes, they did disappear for me one day, but were back once I started using it heavily.

the spots problem will not appear for those who have a flawlessly fit screen
this is why i advice those with lamination issues to get rid of the phone, lamination issues = spots, uneven whites and chance of dust get in

Does anyone have any further evidence that this works? I've got a very light yellow haze/spot in the bottom right hand corner of my screen which I'm not too happy about.
Hoping that it does work because I don't really want to go through the hassle of acquiring a replacement. I will do if the problem is terminal though.
Thanks.

I don't have the yellow spots. But the top part of my screen has a yellow tint. This is my second phone and its perfect apart from this. Only had it a couple of days though so I'll give it time to see if it will fade.
I can only do a swap once more and I don't want to end up with a worse phone and have to send it away for repair.
Dilemma!

[q] screen burn in issues?

I have had my note 2 for 8 months now. Only recently i have heard about the screen burn in issue that is the low life of the screen especially the blue pixels. since i have to use this phone for another 2.5 years or such, what should i do about this? can i get the screen repalced while my warranty is still there and what do i say?
pls help!

blue shouldn't really be a problem.
they made the blue subpixels bigger to compensate for their shorter lifespan.
you can also increase your screen's lifespan by using primarily black wallpapers, black themed apps, and night mode in browsers and e-book apps.
a convenient bonus is that this way you'll also increase your battery life, because it costs almost no power to display black on an OLED screen.

I started having the burn in effects after 6months of usage. And it doesn't follow a pattern it's just a random mark that shows on grey colours. I doubt your warranty will cover that as its a widespread issue that Samsung seems to shy away from, but you won't lose anything if you try to get a replacement just make sure you can easily replicate this issue when you try to show it to the service center.

[Q] Anyone else experiencing AMOLED burn-in / Image retention?

Has anyone else experienced bad screen burn-in / image retention issues with their Note 2?
I've only had the phone just over 90 days, but I've already got some pretty severe burn-in. I use an app for equities trading several hours every day and after a few months of use, the icons and other parts of the app that remain static are plainly visible at all times on any screen that isn't completely black.
For now to slow it down I've re-themed the app and replaced as many static elements as I could with transparent .PNG files and no text.
Any idea if Samsung will replace the display under warranty for these types of issues? (From what I've been able to find, it sounds like they refused to cover it for the S3, then reversed their position and began covering it for some folks - curious what their policy is now)
Here's an example screenshot - this is a blank white screen. It's MUCH more noticeable in person.

Although I havent had it in my note 2 yet, my galaxy s2 had it. I went in to sprint and they swapped it for me because I had insurance. Didnt pay anything. Goodluck though.

I had it bad on my S2. The notification bar and active apps icons were visible on all white and blue screens and so was my keyboard. Sprint sent me home said they don't see that as an issue and the phone works fine so as long as it worked they don't care. Samsung on the other had took down notes then asked me to ship it to them. Never got to send though because the lady refused to be without a phone. As of now my Note 2 has been burning in the notification bar again after about a month of use. I think that's why they made the S4 notification bar the same as whatever ur background is.

Because the damage cannot be reversed, try inverting your screen colors to see if you can get the other pixels to burn in and equalize. I did about 5 minutes of Google research and saw that the blue pixels burn out the fastest, so trying a negative color should burn the rest of them. Inverting colors can be found in Settings --> Accessibility or (in CM10.1) Settings --> Advanced (under device) --> Screen (tab).

Thanks for the suggestion..
I'm giving that a try, but I imagine it'll be hard to even out ~3 months worth of 4-6+ hour a day usage..

Probably, but it is a fix. Your only other option is to let it continue burning out the pixels as before, without inverting the colors, in the hope that you may be able to RMA/warranty the thing. I guess AMOLED screens are known to have this issue. Call up Sprint or Samsung and see what they will do if the problem gets worse.

All monitors will do it, given enough time.

Apparently for Samsung's Amoled displays, "enough time" equals ~90 days of several hour a day usage.
I was aware that the display could suffer from burn-in/image retention, but I had no idea it would happen this badly and this quickly.

Pixels

Hello there guys.
I just wanted to ask you this: have your HOV had any issues with dead pixels ever? One day I just noticed a really hard to spot but surprisingly regularly placed dead pixels. It was just another day, I unlocked phone, checked time, kept living my day like I would normally do. Then when I entered my dropbox app, I noticed those pixels. They are only spottable (still you need to focus to see them) on white bright backgrounds. I tried this Dead Pixel Spot and Fix app from google play. It basically flashed my screen with colors for around 15 mins in hope of reviving dead pixels.
Unfortunately it hasn't helped. They are nothing major, but once I spotted them I know their placement and I see them with my brain not eyes if you know what I mean.
I haven't done anything that could harm them. It dropped few times but nothing happened just seconds after. I have it in case too. Tried to press some spots on the phone in hope of fixing it but that seems not to be the case.
Any ideas how to fix it, any feedback on your HOVs?

I think this has something to do with the "wire" or "tape" connecting motherboard with lcd. Is that possible?
