Epic Touch 4G screen question - Samsung Epic 4G Touch

Hey guys , I have a problem, whenever i browse a site with a gray background, the screen is all the way down from its brightness ( since i use it indoors most of the time) i see like a semi black blurry line coming down top half the screen, you can notice it more in a gray background/image then with a color, but if you notice where the blurry line is, and is actually quite thick, though after you notice it, and switch to other colors, you can tell that there is a contrast difference between the color background and where the line is..
Im taking the phone to the sprint rep, i've already mentioned it to the Phone operator, and she mentioned she will note it, and i can just take the phone in.
( taking a screenshots odviously is useless, I'll bring up photoshop and somewhat portray what i see on the phone screen when i get home from work )
Though my phone hasn't been suffering with the android OS over percentage usage or anything of sorts, no LOS or nothing else, just the Wifi Scanning Bug..
If u over look it, you wont see much different and more when the screen is fully bright, but when the brightness is taken all the way down,you can see it! wtf... so i might as well take the risk, and see if i can get it replaced and hope that the next phone will be good too eh?
Could it be some Semi-dead LED, or burnt?..
I know that the way i write makes no sense lol, sorry english is my second language, im cuban

If your within your 30 or 14 day return why not? Obviously its bothering you so get new one. But do it right before your 30 day is up cause hopefully the second batch of epic touches will be out

Anyone with a VZW Gnex have screen burn-in? I have 0...

Just wondering because I've seen a few posts already about screen burn-in, but I've had my Nexus since launch and have no problems at all. Is it because the people that are having the issue are using the GSM version and have had it longer? Is it because those people have their screens on all day?
I'm just trying to get a baseline to understand where the problem might be coming from. Don't get me wrong, I'm not in highschool so I have no need to keep the phone screen on 4+ hours a day (I average somewhere around 1:30 a day, but most of that is reading and answering texts/emails)...but just curious.
For anyone with burn-in problems just post which version you have (and when you got it, if you could) and the average screen on-time per day that you have. Maybe this could lead to a "best practice" document to keep it from happening to others!
I am afraid that this might be a redundant post you just made.
There is no physical difference between GSM and CDMA variation's SAMOLED screens. There should be more difference between which factory and/or country it was made than between GSM and CDMA.
I know you have already, but please refer to the posts made on:
http://forum.xda-developers.com/showthread.php?t=1509123&page=2
And I'll re-post the post I made over there on here as well for your information.
----------------------------------------------------------------------------
This will probably happen to all of us to some degree sooner or later.
The image retention that lasts 1-3 seconds we might see within a month or two usage is actually one of the characteristics of AMOLED "Ghosting effect"
which is not the same as AMOLED "reverse led fatigue" (or although technically incorrect but more widely understood term "Burn-ins") which maybe seen as permanent image retention shown as yellowish outlines of icons / keyboard outlines, etc.
Sadly, there's really nothing you can do about this problem after the fact, except to change the screen itself if it is really bothersome. Or you may try to change/delete/make transparent of the permanently placed icons/other objects/pictures to try to reverse these effects.
The only preventive measures would be changing screen rotation from vertical to horizontal, and make sure you don't have the screen on at a stay still image (preferably set auto screen off to 30seconds or so.)

I'm sorry, you misunderstood my point of the post. I realize the hardware is identical (as far as the screen is concerned), I'm more interested in kind of how much screen on-time has a strong chance of creating permanent burn-in. I have a max of around 1:30 of screen on-time per day and I haven't seen a hint of burn-in...so I'm wondering if there's some magic number of on-time that will cause the problem to a much higher degree.
What I'm really hoping for is that, for instance, if we find people with 2:30 of screen on-time seem to really have the issue but people with 2 hours or less don't...then it might be a helpful practice to kind of keep screen time to a minimum above that. I realize it's not really helpful for most people (because nobody wants to curve their usage), but it's a limitation of the hardware.
Or maybe if a majority of the people with the problem seem to keep on the screen for 15-20 minutes at a time...that would help, as well.
Its going to happen. All amoled screens get it. The 2 verizom demo units at the store here have it really bad cause the screen is on all day. If you use transparent top and bottom bar, full screen in browser, and rotate your screen periodically, you can avoid the issue.

Oddly enough none of my previous amoled based devices (captivate, SGSII, Galaxy Note) shows any signs of burn in but GNex shows slight ghosting/slight burn in of the notification bar. It's feintly visible when i open the xda app

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!

screen slowly fading (a bit different case)

If you dont care to reply, dont read. except moderator ofcourse.
tl;dr- screen black. not overheat .. touch works. even after black fading to complete black..d855... no paper/eraser/microwave stupidity..
Before you say its a common thing and is a repeat topic, let me tell you right away, its not..
Description-- D855.
phone screen goes off, more like fades away like some screwed up crt(i can see it going black from the sides and then slowly the whole screen)
when it happens -- anytime. at any moment.
what all i tried-- none. i find the paper logic stupid. i believe that if its such a bad processor, i might as well throw it away and buy anew one. i dont think its cpu problem..
why i think its not a cpu problem-- bcoz my touchscreen works perfectly even when device is fading. in fact at times when i lock and unlock again, all gets back to normal. no temperature related behaviours. it can happen even in a freezer. when it doesnt light up(the screen), phone still remains usable. i infact unlock the device with swipe up and go on home screen and i know where music icon is, and i click and then play cyanogenmod music player ((so use its viper4android even if screen is screwed).
no one mentioned whether during black screen the touch and all were working or not. mine is... so i feel its either the screen unit or the wire that connects it.
woyld really appreciate a proper answer if anyone could help me with this. i mean the word 'proper'/.. if any extra details needed, let me know, i will update. i just wanna pinpoint the thing thats causing the issue so that i can get part replaced if not super expensive. thanks.
PS- my battery has red indicator. like real bad since 3 months or something after it got in contact with water/. no device damage though. last time when it turned red, phone simply used to reboot randomly bcoz of low power for device to consume, but never used to look like some CRT screen slowly fading to black from sides crap.. so yeah.. thanks again
i think its the battery

Image Retention

Hey guys, got the phone for a few days.
already got burn ins from whatsapp. the white textbox is two times burned in (keyboard/without)
if u open up a dark grey picture u might see it as well.
just have seen it by an accident when opening "simple gallery", its base backround color was grey, so i found the burn ins.
i am not sure if all displays are affected by the burn ins, i will return mine :/
oh no. can u install aida 64, click on display, whats the panel id.
I've been using mine for almost 1 month and I have no image retention (btw it's image retention, it goes away . Only amoled's burn -in)
tianma td 4310.

Thx for your answere. This morning it was a way better. I know that only amoleds were known for burn-ins. so yeah, seems like it´s only "image retention", anyways for just a few days usage i am pretty disappointed.
will keep the phone for now and hope that it´s not getting worse

Are you on MIUI or some custom rom?
If you are on a custom rom, go to display and then to live display and then to colors and from 100% go to 95% to all of them. This happened to tianma panels on Redmi Note 4 too on custom roms.
This also happens to every LG since G4. Low-quality LCD Panels.
There is nothing wrong with your phone , you can rest assured.

atm RR, so far the best rom i guess. but still the only one i tried. had the RMN4 as well, but never issues with the display (except yellow spot, soon warranty/repair)
i just hope for some aosp roms in the future like AEX and custom kernels
but atm the phone is pretty new on the market and we need to wait a little bit
Yeah, it would be nice to have selection of different ROMs.
Can someone post a picture of burn-in...

actually it´s image retention, not a burn in. so it´s not good, but it seems to be okay.
i am not able to take a photo, cuz u would need a better camera for it.
i guess it depends on the apps that u use and how often.
if u want to see if u got it as well, you could try to download a simple grey picture.
for me grey/dark grey worked good to check it. then open it in fullscreen. u might see the buttons from the navbar slightly.
i´ve been using whatsapp a lot the last few hours, so i could see the white textbox.
atm i am on RR and i recently found out that u barely get max brightness on autobrightnes maxed out. after using max brightness (manual) it seemed to be better. dunno why may be on max brightnes, the pixel get "reset" better. i don´t know.
all in all. it´s okay for me and i guess if u got it, u can recalibrate it.
I installed aida 64 from playstore but I don´t get any panel info in "display"... where do you guys find that Info about panel manufacturer?
Everything is going to be alright. It's just a low-quality screen, nothing can be done except:
Go to display, live display, color tweak and tweak the colors. From 100% go to 95% and voila, everything is going to be normal. Tinama screens are pretty bad, you can go to the redmi note 4 forum and then look for image retention. There are a lot of topics about that and it seems that only tinama screens are affected.
tl;dr: nothing to be worried about. You probably wont have problems on MIUI because the screen is calibrated

Completely false, I have official MIUI 9.5.6.0, I have the phone for 2 days, it created image retention like crazy, god fing damn i didnt expect xiaomi to have such **** panels, so disappointed
@Kusie
Open Xiaomi dialer app and type *#*#6484#*#* and click "software version"
Tianma 4310 display as well. 7 days of usage. 22,75hr + of total SOT. Auto-brightness enabled. Contrast mode : high. Colours mode : standard. Mainly using tatatalk with night mode anabled , XDA labs with dark there as well and SimplePro for FB with white theme. Google keybord green theme. At late night hours auto-reading mode kicks in (100% set)
No image retention/tiny and barely visible navigation bar (or it's just placeboo).
Interesting. Some people here with the same panel face instant burn ins and some don't...
It has to be connected with color schemes of apps, which you are using or brightness levels, which you are mainly on

I saw image retention the first day I got the phone. Changed the color settings to cold (MIUI) and no problem since then.

And why should we be forced to use ugly Cold mode? We lose color accuracy just by doing that, along with the screen having an unnatural blue hue which is also bad for the eyes, I want color accuracy not a screen looking like it's frosted
Hi,
i am on "Linageos 15.1" and today i saw that the color of the screen went to dirty. Before i had very good color representation and now it is like gray, no saturation, no big hue.
While rebooting the phone i saw the last Apps i was running. I can see the Statusbar while i am on bootloader-animation.
My phone runs for about 1,5 months and this issue appeared immediately from one second to another.
So there is no solution to get the display working as it should?
So i have to buy a new phone?
I got a replacement device b/c of the image retention. The display manufacturer is not Tianma anymore but Shenchao. The model number stays the same.

Part of Note 10+ Screen Goes Black

This problem just started today, I've done nothing with settings, have not installed any apps recently, did not drop it, expose it to water, or anything that could possibly cause damage. What's happening is that basically about 1 inch-1 inch 1/8 of the bottom of the screen turns black, and at almost random, sometimes it could go a minute and half or so, sometimes 30 seconds, sometimes within 5 or less seconds. The strangest part? The part that goes black still operates fine to touch, so if an icon or letter of the keyboard, or whatever, is located in that area, it can still be selected/operates. Taking a screenshot to try to show it is worthless since it'll show the screen as just fine, so I attached a picture and a video of the problem from an old phone of mine. The blacked out are will go right back to normal if you turn the screen off, wait a second, and turn it back on. Also, if the blacked out area is there, it'll go away after about a half a second when the screen dims right before the screen inactivity turns the screen off. I've only had this phone for a couple months, I got it back on December 7th 2019.
I learned something else. If I manually lower the brightness to a particularly low level, the black goes away, so it seems to in some strange way be related to the phones brightness level (I use auto brightness), this also might explain why the black comes at differing intervals, as my brightness is adjusting constantly to my surroundings, the time before it comes is either shortened or lengthend based on the brightness.
It doesn't seem that strange that the touch still works in that area as the digitiser and the display are two different things. I would factory reset (because Samsung will make you do this anyway) and if still an issue, take it directly to Samsung, that does not look good.

I was just thinking I might have to do factory reset, if that doesn't work, and it needs repair/replacement, do I go to an authorized Samsung repair place (I know I have one within about a couple miles of my house), it's
obviously well within warranty, or take it to At&t store as I do have that AT&T Protect Advantage coverage for my phone?

Did the factory reset, turned out to be a waste of time. That black bar was showing immediately, right at the setup screen. So I guess it's safe to say that it's a hardware issue, defective whatever. Funny story is that when I bought this phone, my att store only had two of them left, one was immediately defective, it wouldnt get past the main logo screen, and now I got this one and it became defective within just a couple months, got to love it.

Just left AT&T store where I initially purchased the phone. They're shipping out a brand new note 10+ to me today and I'll get it tomorrow ?
Glad to hear! That definitely sounded like faulty hardware. Funny you saw two failures, I guess it will happen with such complex devices.
Note 10 plus screen goes black
Hi i thought i was crazy until i saw your thread. The same thing is happening to me but it does not go continuously so id see two red squares first theyre really small and they appear anywhere on the screen then if try to screenshot them they show upblack in the screenshots instead of red . I just need to know if anyone found a solution yet because my phone came with the warranty booklet but it wasnt filled out.

You just need the proof of purchase, or, if you got it on contract, the contract itself will suffice
