Red Screen of death issue

I have had the Sprint Epic 4G Touch since launch day and today everything on my screen turned into a deep shade of red for a couple of minutes and I thought it was a dead screen I would have to return to Sprint and then the normal color returned out of nowhere. Does anyone know if this is something I triggered or was this just a glitch? The home button, screen off/on, changing screens did not fix this problem. All functions were working from what I could tell and I could make everything out on the screen and it was bright but everything was a shade of red.
My phone is stock and I have Go Launcher running on it with many Go Widgets. I had about 50% battery from what I remember. I may have had the Words With Friends application running at the time if anything. I have a few emulators and ROMs on my external sdcard that were not running but everything else on my phone is normal.

Thos happened to me also. i am rooted with stock kernal. was weird. i rebooted and hasnt done it since then.

it happened to me once since I got my phone but hasnt since. It reminds me of the red render effect in CM 7. That's the best way to describe it.
It's similar to this, not exact but similar..

this also happened to me once for a few minutes...freaked me out...went back to normal and not since

Since a screen shot was made
Its probably a bug sammy overlooked
If we blast sammy's twitter about they will be forced to give us that update
Why you ask
Because the other variants of the gs2 hasnt come out yet and if they wait super long to give us these updates chances are less ppl will buy the gs2 for t mobile and att

then lets blast away!! consumers shouldn't sit aside with faulty products because a company is too big to admit to its faults

This is extremely close to how it looked on my screen. I tried recreating it but couldn't. I'm glad I'm not the only one. Like I said everything was functional I just thought the screen took a nose dive on me. I'll blast sammy's twitter also.

I've had the same strange red shade. Thought maybe it was a hardware problem; glad to see it wasn't just me.
I've had another weird screen mode issue - "safe mode." No idea what this meant, but didn't notice any limitations. Just had a little shaded rectangle at the bottom left of the screen no matter what I did. Had to restart the phone to make it go away.
I've also had a warning that I was overheating the battery by flying through Manhattan in Google Earth with 3D rendering turned on. Not a bug - just didn't think it would be possible to pull that off when the phone is in an environment of standard room temperature.
See the attached screenshots.

[Q] Would this qualify as defective?

My screen shows banding on screens with gradients, like the call log screen, or screens with certain colors, like when I'm playing wordfeud. Even when I'm browsing the white background has faint horizontal and vertical lines.
All of this is only visible when on the lowest brightness setting. So when I'm browsing in bed at night etc it's really annoying.
I went to the (3) store here in denmark, but because it was a well lit room, the problem was barely visible and they said they'd have to send it in for "assesment", and best if i could come back in January and send it in (for 2-3 weeks). I'm just afraid they'll just return it with "problem not found"
I DID manage to report the problem to them on the 14th day after i bought it, their own DOA limit, but I've got a feeling I'm going to get screwed. Especially because the in store phone ALSO seemed to show the same color banding on the call log background.
I've tried taking some pictures that maximize the problem here: http://imgur.com/a/CbKYi#9
Are you guys seeing the same thing on any of your devices?
I love the phone to death otherwise, but it's like a scratch on a brand new car, it's annoying me a LOT.

unfortunately, that's just how they all are. has to do with the display type. both of the nexus' i've had were the same way, as was the display unit in my local verizon store.

You aren't seeing "banding" in the traditional screwed up screen sense, you're seeing the back of the display. I think it's just part of being SAMOLED and Pentile. I never noticed it until I started reading all the threads about people complaining over "banding" (and I don't think you're complaining LOL ).
Bump it up from the dimmest setting just a bit and most of it will go away. Our dimmest setting is REALLY good, at least compared to my old SGS. I also like how are screens don't have that SGS SAMOLED blue tint to them.

go to that call log screen again and press vol down + power. then look at the screen shot on the computer.
it looks the same
the background is ment to look like that

All 4 phones and 7 models that I've gotten to use from Samsung have this problem.
SAMOLED just isn't very good yet.

happy to hear my phone is not defective, but then again im very disappointed that this is a quality issue with the phone.
I read tons off aritcles discussing the difference between Super AMOLED and Super AMOLED plus (pentile and RGB) and this forum probably did the best job of explaining it
now is this also the reason why whites arent really white while having hte phone in auto brighntess? is the screen is dim, my "people" app is not white, actually far from it. but when the brightness is maxed out it looks magnificent

I was disappointed by the screen quality at first too, but the more I use the phone the less I notice it. I've even started to really like other aspects of the display that were lacking in other phones with a "clean" screen. Colors are much more vibrant for one, this is very visible when watching videos on the phone when I'm at the gym.

White spot or white pixel on white, what is it exactly?

Im quit perplexed about this so if someone with experience can explain

i posted this a lot before but i want to know, there is some grain visible in bright angles, and actually i have two of those white spots visible at angles, one of them is pixel size the other as you can see in the pic is quit few pixels size
but it doesn't show on black, very minimal on blue, shows on every other bright color
whats is itexactly, a dead pixel would be black and appear on white, a stuck pixel would be white and appear on black, dust would appear under sun light or flash light when the phone is turned off
but its not any of those, is this imperfection to the screen glue or dust in the glue or back light bleed?
The grain i assume is just glue imperfection but this white dot is driving me crazy it's mid screen and ruins the nice view angles of the One X, the screen is fit well actually
I tried pixel fixers but no luck, right now i'm trying to leave JScreenFix running for two hours

I have one of these, I think it's just a hot pixel. I emailed Clove and after seeing a photo of it, they said HTC won't replace for one bad pixel. Same thing as yours, only visible on white screens at odd angles, can't see it when looking at the phone straight on, and can't see it all on anything other than bright colours. Wish it wasn't there, but it's not a big deal to me, the rest of my phone is fine. Let me know if a pixel fixer works for you, haven't had luck so far. But I haven't noticed it lately.

a typical hot pixel should appear on all the time even dark background, anyway no luck with JScreen except that the device crossed 55degree lol

Got the same issue. Send it for repair today, it bugs the hell out of me. If they wont replace my screen for i'm gonna ask a refund.

I just noticed that I have one as well. Not sure what to make of it really, could be a lot worse but its pretty peculiar. Anyone managed to shed some light as to what it is or been able to remove it? Or if HTC will repair it?

I have one in the middle of my transformer prime, irritating but prob the least annoying type of screen deffect. Only noticeable on white backgrounds

white spots while charging in off mode
I m facing some strange issue in my canvad hd...i seen some white dots on screen during charging in off mode..when cell is not on...the charging image shows..in just above i seen white dots...i thought it dead pixel...but when i on my cell ..this dots gone...no dots there...only in off mode charging...they shows..what is this..ny idea...
Or nyone facing this issue ?

Strange screen issue

I've found something odd with my screen, and although I intend to do an exchange on my S3 I figured I'd share it here to see if anyone else has seen it too.
What it seems to be is that a couple chunks of pixels go entirely black when their section of the screen calls for being black, while the rest don't. I'll try to show you what I mean:
This is a shot of my screen, running a screen test app on an all-black image. It's extremely hard to get a picture of a dark screen in a dark room with a cheap point-and-shoot, and you'll have to ignore the stuck pixels on the camera's CCD, but the red arrows point you to the bits in question (I've also turned the contrast all the way down, and brightness all the way up, in photoshop because otherwise the spots weren't very clear... and still aren't in focus... but in person these are easily visible as two dark spots in an otherwise gray background when you look at the screen in a dark place). You'll want to view it at full size, and again I'm sorry the image is so blurry but viewed in person the "blobs" in the image are in fact crisp edged vaguely tetris-block-shaped pieces of total blackness surrounded by dark gray.
For comparison this is my girlfriend's Sprint S3 screen shot with the same camera under the same conditions and with the same photoshop effect applied.
If you want to see if yours does the same thing, download "Screen Test" from the market, turn the screen's brightness up all the way, change it to the black screen (the second testing screen), then go into a totally dark room. You may have to look just off to the side of the device to see them at first, but once you've done that and seen the spots you can't un-see them.
Lest you think I'm being overly picky (although I would argue any defect in a device I paid $550+tax for is one defect too many) it IS possible to notice this even under normal usage conditions. I kept seeing a spot on the Facebook app every time I would reload a page, and every time I thought a piece of something had gotten onto the screen, but before I could wipe it away it had disappeared. It may be a minor annoyance, but it really bugs me, so I'm going to exchange it. I figured I'd document it before I did, though, just in case anyone else had seen the same things.

A lot of people have this issue, including me. But since I literally never see it unless I'm using Screen Filter at a low percentage, it's not much of a bother.

The only time I see it is when i play draw something.

Screen blobs....
They have plagued Samsung screens for a while now.
The sad part is.. from my experience with the blobs, Even with a device that doesn't have them they eventually show up.
Found on the following
My s3
Galaxy note (over 6 tested)
Galaxy s2 (a few tested)
Galaxy s2 skyrocket (over 6 tested)
Even the galaxy note 2 I recently examined
They all have them

Damn. Just checked my s3 and have a 1/8 inch line running down the right side of screen

My search led me here! I myself noticed this tonight while I was watching Underworld Awakening in my bedroom with the lights off. I have a nice blotch on the center right and a few spots scattered throughout the screen. Looks like I will have to unroot and watch this out:/ what a pain.
Here is my screen shots may be hard to see from these pics.l but its definitely there.

EDIT: I decided its not that big of a deal. I don't watch a great deal of movies on my phone anyways. I mainly use my tf700t for stiffy like that

Yellowish tint on screen?

Might be being paranoid due to 2 XL screen issues but has anyone notice a yellowish tint to the screen? It almost seems like off axis is more pure white and looking directly on is a warmer white if that makes sense. Might try to take pics but not sure I can capture it.

I haven't noticed any hardware problems with the display yet, although I do have black clipping in movies.

Instead of starting a new thread I decided to post my issue here because it's screen related. I don't have any yellow hue with my screen. I unfortunately have a pinkish hue on the right side of my phone. I saw it immediately after powering up for the first time. Kinda reminds me of the S8+ fiasco. It's just in the right side and starts about the middle of the screen and heads up to the top. I called Google and they took my issue very seriously. They wanted pictures and it's a very hard thing to capture with a video or pic but they said they could see it in one of the pics I sent. They have me play some white screen YouTube video and wanted a picture while that was playing. Anyways, they took my info about the issue to some higher ups and called me back about an hour and a half later. The person I dealt with was nice but a bit pushy with getting pic results. He was concerned about some widespread issue because the phone was just released. So he said that these panels have some color shifting (ok? Already went over that) but offered to send out a new replacement. That is me basically buying another and not getting charged unless my original phone isn't returned on time. I'm very disappointed with the screen having this issue. I went through the whole blue screen last year. I had to get two replacements until I received a "good one." Anyone else having screen issues with color?
Sorry to hear about your yellowish screen issue. If you aren't happy with it I'd return it. There are a few friends of mine that have great screens

Here is what I'm noticing. Maybe that's just the way it is and it's something I've never noticed before. The funny thing is I have a Xs Max and the Pixel looks better. Interestingly enough the second picture (pure white) looks similar to the Xs max if true tone is turned off.

My display is great. Beautiful. I'm grateful too because I went through 7 2 XL's before I found one with a display I could deal with.

Adaptive brightness, if on, will turn the screen yellowish in low light conditions.
Otherwise, I didn't notice anything since I received the phone today. I've been using it all day.

Nope, mine has been fantastic. Looks great.

Going to have to go check other devices in store. Can't tell if what I'm seeing is normal without another unit to compare.

No matter what phone you get an OLED screen is a lottery to how even the whites are or the degree of hues

+1 I've seen some "comparisons" saying the 3 was warmer than the 3XL they saw. I'm opposite here. Received a 3 before launch day. Nice, cool screen (which is my preference). Phone felt way too small for me so I picked up a 3XL at Best Buy yesterday. Quite a bit warmer than the 3. Returning that one today haha.

Haha If it's noticeable straight away and takes away the enjoyment of the screen then a swap is the best way. I've had devices from Samsung, Huawei, OnePlus, Google etc and I've had bad tints or uneven whites on them all..so part of the oled game

Do you have any updates on this? Did you try to contact Google?
