Hey,
I've had my S4 for a few years, it is unrooted and running the stock Touchwhiz rom 5.0.1.
Whenever the devices screen is about to turn off it flickers green, it started a few months ago and was hardly noticeable, but within the past few weeks it has gotten worse. It sometimes flickers while in use, but usually on flickers when the screen is about to turn off. It seems to only effect the lower 4/5ths of the screen.
I have a video, but I'm a new user and XDA wont allow me to post links yet.

If factory reset doesn't solve it then you should prepare for the screen to die at some point. Or maybe it's the GPU. Either way, something's gonna break.
I had something like this after dropping my phone onto a heavy tiled floor. it started with a dead pixel and whenever the screen dimmed before going off the bottom third of the panel would flicker.
eventually a bright green line went thru that dead pixel from the top to the bottom of the screen.
I lived with it like that for over a year until the digitizer started to become unresponsive.
make sure you get a genuine amoled replacement screen when you finally accept the inevitable. I got conned with a cheap knock off LCD replacement display which has terrible terrible contrast and can't cope with shadows...

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.

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.

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!
How can i tell the difference between them , i have a few little dots on the top left of my screen i notice it when i turn the phone on and also when the screen is off.
If it's in the top left, that's likely dust. That's a problem area in HTC quality control for this device.
Also, if they are there when the screen is off then its' certainly dust.
Dead pixels do 1 of 2 things. They either don't work at all so they are black when the rest of the screen is on, or they stay 1 color constantly lit so they are lit when the rest of the screen is black (not off)
If the screen is powered off, even dead pixels don't stay lit.
Also, dead pixels aren't nearly the common problem they were on LCD screens just 5-7 years ago. I remember going through multiple computers monitors once trying to find a good one when LCD monitors first became affordable. It was a nightmare.
Now...you can buy $1000 big screen LCD TV's and not even worry about it.
Anyone ever come up with a solution to the corner dust problem. I have a patch about 1/2 inch by 1/2 inch in that corner and it's so thick I can't see the notifications in bright sunlight. I'd rather not take it apart and wondered if a powerful vacuum or something might work?
Most people send it back in for a replacement
Very simple - if you can see something even when display is off then its dust else dead pixel.
I am thinking about getting a Galaxy S4 now that my contract is up. I'm a little OCD, and I already know a screen burn-in will annoy me. Will the screen last two years till my next upgrade? I mostly would use the phone to text, listen to music, and browse the web.
If a burn-in has a high risk of actually happening, do you have any suggestions for another phone I could look into? Thanks.
Never had this happen on any Samsung phone I owned before.
I have had both the Captivate and SGS2, never had any screen burn-in with either.
Didn't see any from S1-S4.

amoled screen dont burn, at least not in the traditional way plasma do
One day, i left my S3 on my charger because i was going out of the country for 3 weeks, for some reason, my screen stayed on and it never shut down, it was on for 3 full weeks, the phone was pretty hot but there was never any impact on my screen quality
Well people on YouTube tend to say it burns in...

I've had all the Galaxy S phones and both Galaxy Notes, I've only seen burn in on my GS2. It was on the wifi/network signal portion of the status bar and was only noticeable if I really looked at it.
But then again I didn't have any of them for two years.
no such animal as burn-in. get it. you'll love it
Burn ins do exist....but they typically happen in areas you will never notice
On my Samsung infuse, I got a burn in on the status bar...it was only visible on a pure whit background, and even then it wasn't that noticeable...and since the status bar is up 99% of the tome you would never notice...I didn't notice it until I had my phone for about 2-2 1/2 years
It also got a slight burn in from the Samsung logo on bootups, but this only happened due to my constant flashing of roms and kernels I was compiling...self testing...and a lot of times they wouldn't boot...they would get stuck at the Samsung logo...and often times I would leave it at that logo for hours (pure black screen with Samsung written in bright white)- so three years of development on my own cause a screen burn in...this would never happen to anybody but those who are constantly flashing things they know probably won't boot
So do burn ins happen? - yes
Is it likely you will get one in two years? - no
If you get one will it be noticeable? - most likely not
Do burn ins happen quickly? - no

Nah, you should be fine. Unless you leave the screen on for hours with static image on it on higher brightness, you should be fine. And I'd assume it should be much better with newer AMOLEDs when it comes to life span of the screens.
Doesn't seem to be a problem except under extreme circumstances. This is my first OLED phone and it is amazing. I use mine in bed in the dark a lot and the blacks are glorious. I've been spoiled. Don't think I can go back to LCD now.
So the charging cover of my s5 broke off without any undue application of force. I decided to replace it anyways by taking it to samsung. Their incompetent engineers did something with it, the cover wasn't in stock and I got my s5 with a flickering screen under low light. After 2 weeks they finally managed to fix it.
Now comes the real dealbreaker, my screen has started ghosting, whenever i see something black on my screen while reading a webpage and scroll down, there is a noticeable ghosting effect and all screen becomes blur. It happens with other colours too like red and is more noticeable under low brightness. I am afraid to take it back, dunno what they will damage this time. Has anyone else experienced this? Please help.
Hey guys,
Yesterday night before i went to bed, three blue spots appeared on the screen.
The degree if their appearance depend on the content shown on the screen -
*if viewing bright white light (such as an artical with white background) the spots are nearly invisible
*when darker colors are shown, for example when i pull the statues bar down - the spots are visible and annoying.
*when the screen is completly dark, the blue spots are highly visible

I've never dropped\hit\damaged my phone in any way, i had the case\glass a few days before i even had my phone, and yesterday night those three spots just appeared out of no where - what should i do?
Images not working. I haven't got or seen blue dots on screen before. I would suggest contacting Motorola.

get intouch with Motorola , thats a fault
Does anyone know why this happens? I just happened to me after more than six months of peace.
It's happening to a lot of people. Same with me, and the spots on mine were in the center near the bottom of the display.
Happened to me randomly one month after i got the phone. Had to get replacement from moto. Haven't had problems with new. Been about 8 months. Fingers crossed.
My wife and I each have the same phone her's has had the same blue dot for a month or 2 now: http://i.imgur.com/90U6BMR.jpg
Mine just developed a small white dot in the upper right corner of the screen.
ugh.
I believe these are from pressure against the back of the LCD. After I replaced my screen due to cracks I noticed that I had to play with all 20 screws a lot becasue if even one was too tight it would make a spot on the screen and I had to keep adjusting all the screws slightly, it was like putting a head on an car engine, slightly too tight on one screw would often cause inperceptable torque on the LCD and then a spot would appear above a different screw. Took a lot of adjustment and its still not perfect. From the pictures I'm seeing of the large blue spots and their locations, I'm susupicious something got jarred between the LCD and MB which is very sensitive as I said almoast imperceptable screw torques are enough to cause very similar artifacts (though they could also be just causing some kind of ground issue also, they are dead white with light blue around them, very small becasue the screws are small, and also very particularly pronounced.
So WILD guess is three things:
1 something not sharp or pointed moved somehow and is causing pressure on the back of the lcd directly below the blue spots.maybe those 2 rubber boots that cover two connections (you see them immediately and must remove both when doing anything to the phone after the glued on back is off.
2 LCD Failure
Probably 2 but if you are capable and adventurous check 1. Or ship it if still under warrnaty. Anyone know how long is the warranty? If you buy off of MOTO like I did?
I must be the special one. I have a red dot on mine.
I noticed a vague blue spot in my moto g 2015 today as well. When i press it lightly, the center of the spot turns to a small sharp bright white dot.
I aggree it must be caused by internal pressure. I had the same sort of spot on my HTC Desire. When i replaced the battery, the spot was gone. Turns out a drained/old Li-ion cell expands quite a bit, this caused the pressure from the inside on the screen.
My Moto G is only 6 months old so you wouldn't expect the battery to be faulty yet... Too bad the Moto G doesn't let you replace the battery yourself in an easy way like with my old HTC.
Did anyone experience the spot disappearing after replacing the battery with a fresh one? And does anyone know if old Moto G batteries look thicker than normal after they die?
I just started seeing this about a month ago, mine looks like the Pepsi logo, red and blue orb.
