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

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.

My thoughts on the Galaxy Nexus

Hello. Thought I'd add my thoughts into the mix, kind of a mini-review but not very well written and missing lots of things.
The hardware is awesome. The screen really is amazing, and in particular I like the way that it displays blacks so well. Because of this you usually can't see the edges of the screen and it looks fantastic, and coupled with the lack of hardware buttons the front of the phone is really sexy. The back on the other hand isn't as impressive, but it's ok. The "hyperskin" is more hyperbole, and doesn't really help you grip the phone much. Overall it's quite slippy really and I do feel I'll probably end up dropping it sooner or later.
The processor seems to handle everything fine and keep everything running smoothly. GPU I haven't really tested with any 3d games so can't comment on that. Battery life I've found much better than I expected, although I haven't done extensive testing on this. Here are the current battery stats, 18 1/2 hours with about 13% left:

}
I haven't really tried out the camera yet so can't comment on that. Call quality is good. Oh and size, I find it a bit awkward sometimes to pull the notification bar down or to hit the back button in the top left of the screen, ie. in the market app but overall I find the size to be good (I have quite small hands). The light weight and thinness kind of make up for the large size.
In terms of software it's as you'd probably expect - awesome. Face unlock doesn't work well in low-light which is kind of annoying. I'm not sure if I'll keep using it but I like it as on my old phone I only used swipe-to-unlock, so it's a bit more secure with this. I'm not exactly worried about someone taking a picture of me and then robbing me anyway.
The hardware acceleration makes a huge difference. The UI is nice and fluid and it's just really enjoyable to use. There is also an option to force hardware acceleration for apps as well which makes a big difference too. For example Twitter was a bit jerky and laggy before enabling it, yet with it on it's perfectly smooth and fluid. The News and Weather widget however doesn't seem to be accelerated; it's really jerky and slow.
Auto-brightness is something that needs tweaking I think. It's often too low (to save battery no doubt), and needs to be raised a little. On top of that sometimes it doesn't even seem to work properly. Earlier on I was looking at it and thinking how it's too dark and then it suddenly jumped up to a decent level of brightness, even with no change in the ambient lighting. I've seen this a few times so I think maybe it's a bug which needs to be ironed out.
The people app is really brilliant, and the G+ integration is really great (if only more of my friends used it..). The swiping thing they've got going on now in various apps is really good and hopefully we'll see more of it in the future. The dialler app is nice, but I am disappointed that you still can't start typing the letters of your friend's name to bring them up like you can on HTC phones.
That's everything I can think of for now, but overall I love the Galaxy Nexus

SGS Screen Booster

So I've been looking around at how to increase screen FPS/Sensitivity/Overall responsiveness and came across this app today. I've been using it all day and I can notice considerable increase in screen response. Typing has been much easier and I've made less mistakes and scrolling has never felt easier. I recommend everyone give it a shot and hopefully this could be built into ROMS/Kernels. It says SGS only but many have found it to work on their devices.
https://play.google.com/store/apps/...Nob3A0YXBwcy50b3VjaHNjcmVlbmJvb3N0ZXIuY29tIl0.

So what does this app actually do? Does it simply just adjust built-in variables in Android for screen response (like the touch threshold, etc)? Or does it do something else entirely? Or maybe placebo? =P (although I doubt that last one is the case, based on the app reviews)

I don't have a clue how it works. All I know is that the screen should be this sensitive out of the box. I ran 12k in Temple Run after I did this and my highest previous run was 6k.

It certainly seems to work, great spot! ;-D
What settings have you found optimal?

Do you use an own configuration or a pre-installed one?

Don't know if it's a placebo effect, but now the phone feels a snappier

While I don't use this on SGN, I can vouch for it working. Used it on my old Hannspad (gTab) and it worked wonders for the sensitivity on that, so much so the device was unusable without it.
Regards.

The better responsiveness is especially noticable when you use a screen protector.
It just works perfect in my opinion

I'm def gunna try this on my Transformer Prime.

Going to run this on my xoom, that thing has terrible sensitivity

i dont really notice a difference at all. what setting are you using? regardless, i am going to use it on my touchpad and see if that helps with its lack of sensativity.

I use the super optimized preset. Make sure you apply the settings.
You guys can also try these this build.prop mods to see if it helps.

Is there any risk to using this app at all? There is a reset button to reset it to the default settings, right?

No risks so far. Yes, there's a default settings option. But you also have a check box to set on boot and if you don't check it the settings will go to default on the next reboot.

didn't notice any difference on my galaxy nexus

I used this on my former HTC sensation that had terrible screen responsiveness in its first days. Worked great. Didn't feel the need for it so far on Gnex.

[Q] upgradeability ,text sharpness and screen burn in?

hi,
as someone who wants to finally board the android train, and is particulary impressed by the note's concept, i was waiting for thw GN2 to be avilablele, but i have a few questions:
1. i intend to use my next device for approximately 2-3 years. i've read here about concerns regarding the GN2's "outdated" hardware. normally it wouldn't bother me, but it's my understanding that the A15 is a huge leap forward, and in light of HTC's announcement about updating only to 2012 devices, i wonder if the A15's could become the new standard and when key lime pie (or the next one) comes, it would be too demanding in samsung's eyes and it won't be officially supported. in addition, some devs. dropping development for exynous based phones combined with the fact that afaik, CM doesn't support the s-pen's features (which are a main part of why i chose this device) may leave it behind for me. is it reasonale to expect at least 2 years of support by samsung?
2. has anyone used the handwriting recognition to solve math problems (i.e. infinitisimal calculus)? does it work well?
3. how much time can i keep the screen on wih a still background before i risk screen burn in?
4. does the screen appear not so sharp while viewing text, due to the somewhat low pixel density?
5. i've read here a comment about the note 3 supposedly released on march 2013. is that a popular\ reasonable opinion?
thanks a lot for the patience reading this post, and in advance for your much needed help!!

Two years of support will definitely happen. The old Note 1 is still getting updates, and recently includes the multi-tasking sidebar.
I've used the handwriting with equation inputs. It does not solve calculus for you. You just get to input it.
Not sure about burn in. But on HDAMOLED screens. I've heard upwards of 2 years on moderate usage.
The PPI thing is personal preference. I came from iPhone 4, and while the Note 2 PPI is lower. It does make up with its monster display.
Note 3 rumours need to be taken with a pinch of salt. I don't see it happening. Although anything can happen. There are credible reports of Apple releasing i5S as soon as feb or march.

I can only comment on text sharpness. And in my opinion it is perfectly fine. Words still look great when zoomed in etc. All the round letters look round abd not jagged

that's very reassuring. does "support" usually mean implimentation of certain features or the full ver. of android?

i read about the partnership with wolfram alpha, since i check many of my results on their site and given the note's ability to recognize handwriting, i thought it would save me a lot of time. is it not possible or did you not try it on wolfram alpha?

full version of android. seems like my old galaxy s2 will still receive full jelly bean even though it is 1 1/2 years old. Samsung is actually quite good with updates compared to other oems (except google and apple of course)
I used s note with wolfram alpha a little. It does work flawlessly for what I tried. Didn't try it excessively though.

thanks for the rapid responses!
since it's pretty much why i need the s pen, can anyone with n7100 try to write some short random integral/ derivative with Exponentiation with the s-pen to see if wolfram can use it? it would erase every shred of doubt i have, and assert this phone as the chosen one..

[Q] Screen brightness auto-changes without any auto-adjust on.

I have all possible options that can auto-control the screen brightness unchecked, and the mode set to Dynamic (even if it's on any other one too), and my brightness set at 45 (again this doesn't matter as I changed it to other brightnesses), but I still see the brightness auto-adjust from time to time. It doesn't matter what app I'm in, or just looking at the home screen. Does anyone else have this happen? Is there a way to make it stay where I have it set? It's not really annoying, but I do notice it, and would like it to stay put.

I had this happen on the S4 and note 3. Supposedly it's a Samsung thing. I did see this though

It's happening to me I made a thread on it too, I've called Sammy and done everything I could I think it's a software issue or one of the sensors is jacked up. In any event I gave it a few days and it's not getting any better it's very annoying to me so I'm returning my phone and getting another one just to make sure it's not a hardware issue. It's the only reason I haven't rooted yet

Its exactly what you see there TW has A " feature ' that dims screen a bit When Itgets a little hot that ls all it is, not hardware problems mine does It when its hot near the camera

Well mine is going back anyways so i can rule out Hardware failure before i root it, Also when i talked to samsung about it they said return the device

So you rule out hardware issues? Maybe the software like I said?. And by the way Samsung always says return. Everything...it's their go to answer for everything lol

Listen to what i wrote i said im returning it to rule out hardware issues, if the new device does it then its definitely software and illl wait for some kind of an update or wait for a dev to get a handle on it. S4 from doing research had the same issues so yes most likely its software but i have to rule out hardware by returning it and getting a new device. My Note 2 did not do this so im assuming its a TW 4.3 issue

Ok...

Other than that i love the phone , awesome device

In the last week I bought a S3 and a N3.
Both do this almost identically.
I thought I was going nutz...

Returning it won't help. It was happening on three S4s of mine.

Conclusion: It's not a phone defect.
I have done some testing, and concluded (at least for me) it is software/hardware combo as said previously (heating up). Since I have the phone set up exactly how I want it (rooted and all), and I really don't want to return it since the phone itself is perfect (no physical defects with buttons, screen, etc), I kept a really good watch on when it does it, and it only does it after I have the screen on for like an hour or so, and the phone itself gets warm/hot. If the temp stays below 95F the brightness stays constant. Only if it gets up in the 100s I start to see it, so I do believe it's auto-dimming to cool off the phone. I can live with that since it doesn't get that hot all the time. Mostly playing games, or heavy browsing on the web using desktop mode, and when it does do it the change is slight. I only really notice it on white screens. I was worried since I thought it was a defect, but that doesn't seem to be the case. I'm super happy with this beast. Best phone I ever owned.
On a related note I do remember my GSII doing it on TW. After I put CM on it I never saw it.

No lux is not the answer I tried that too. I just got my new phone after returning it and it does the same thing . As BobbyPhoenix stated I think it's software related too and it's when the phone gets warm and I think how much it adjusts is based on how hot it gets. I guess I'll have to live with it because I love this phone the screen when full blast puts all others to shame. Hopefully a dev will have a workaround soon

My wife's S3 does the same on Lux, maybe acts a little different but basically overall it's schizophrenic. It's possible it's goofier with Lux installed. Now there is another layer to manage.
