Hello,
So my S7 edge got a replacement display due to being broken like 2 months ago. Today purple smudges started to appear, when I used the device for quite some time heavily and it got quite hot. They disappear when I change display mode or when brightness changes. But sometimes reappear. Is this a defective Display, should I get it replaced via warranty again?
Mine does the same thing, but it has never been repaired or suffered any kind of serious damage. It's not that annoying either.
Could it be some kind of factory defect?
When googling I found it clearly is a hardware display fault. As I had my display swapped by a third party mobile repair shop, they would be the ones to make accountable.
It only occurs at certain brightness settings, and not in all apps/states of display - mostly in those which are really bright like chrome browser without tab open, or dict.cc dictionary app.
I'll keep an eye on the issue and just demand warranty, as this display isn't even 2 months old now. They give 6 months of warranty on exchanged parts. So if it does not go away, I'll just get it replaced again.
It just occured today out of the blue, after flashing custom rom / flashing some stuff and constantly playing on the phone, and it became a bit hot.
It occurred exactly the same to me, after flashing a custom Rom. Now I can't remember which one, but it changed the screen's aspect ratio to simulate the S8's.
After that I flashed stock and the problem kept happening
But I don't think this can be caused by a custom rom... it's a hardware fault.
I hope so because I really wanna install a custom rom ;(
Google the issue - it happened a lot apparently and there is literally no connection to custom Roms - it's a defective Display. I did not have the issue anymore BTW.
I have to get back at this again. I recognized that I can Only see these smudges under certain conditions. I can not see them when I am inside. Only outside, and Only from specific angles - also dependant on screen brightness. When I cover the screen with my hand they disappear.
At first I thought it could also be some fault with the transparent protection skin I also applied one day before first noticing this purple screen problems. But the thing is - they move when scrolling, Only in a small portion of the screen but they go up and down.
The fact I can Only see them in daylight makes me wonder if it's got anything to do with the surrounding brightness sensor that does the automatic brightness and display mode for you.
I find it very strange that I can not provoke the issue indoors, also not if I set up brightness to max.

Hello all,
I've got the SGS II for about 1 week now and at first I thought it was a software issue. The thing is, when I'm on a very light colored background ( Market, facebook, whatsapp or whatever ) You see smudged out stripes from the text or any picture that is on there. They're all faded stripes. I thought it was banding but this is something totally different.
What's even more weird- it only happens when I'm outside the house, so my guess is that the brightness sensor plays a part in this? When I'm inside the effect is minimal to none but when I go out or to a very bright place, the stripes are extremely annoying. ( will take pictures for reference when I get the chance )
Would you say this is a manufacturing fault?
Please help if you've encountered something similiar.
Thanks!
Here are some images, the stripes are not that evident right now. They seem to get worse when I'm in the sun.
Looks like some polarising effect.
Should I return to the shop to get this swapped? It seems to me that the screen is defect???
Return!! It seems alot of people are having screen problems.
Same issue on my SGS2.
Was perfect during one week then theses anoying stripes!!!
Did you perform a 1:1 exchange?
There were similar problems on the Sensation forum and it was found to be app/widget conflicts.
If you turn off auto-brightness and also the power saving lcd brightness mode under display in settings does it still happen? You mentioned it happens when you go outside so was curious if you adjusted brightness manually if it still happens
Sooooo....
Yesterday evening I changed form litening 1.5 to the stock rom on KF1 with full wipe.
After that stripes where still there.
Went to bed.
Woke up this morning: Big surprise stripes were almost invisible!!!
Battery 40%
BUT
today I used the GPS google navigation during 1h and discovered that theses stripes appeared again and they are very strong.
- No link with app/widget, nothing installed .
- Didn't touch on settings display auto-brightness before the problem. Tried after but nope.
I tried this today
(all credits to Cost from french forum tmaddict)
Flashlight to use white light during half an hour.
Stripes almoust disapeared...
Then picture with high contrast and color.
Stripes came back.
Conclusion :
With SGS2 you can encounter a display refresh problem.
Not solved btw => screen defect => exchanging it today.

hey guys
for a long time i am having this issue with my screen.
it flickers sometimes, no pattern of times. but it does flickers almost all the time when i put it on automatic backlight, or if i set the brightness to lowest level, or 1-2 level more than lowest.
at first i thought the battery may be going bad, because i did have battery issues. but now that i have bought a new battery, it still happens.
i read that it might occur because of the s-view covers. but i have s-view covers for almost a year, and it only happens for about 3-4 months.
though i did buy a new s-view cover on august. could this be related? i think i did have flickering problems even earlier than august.
either way, i had removed the s-view cover from my phone, it does seem to flicker less. and weird thing, sometimes it just enters the s-view mode where all screen goes black except the window part... maybe the phone misses the cover
any way. what could be the problem? how can i solve it? maybe i should format the phone and install another rom? i have the latest Omega rom version right now.
thanks everybody.
anybody help?
no one?
I think I've found the best solution out there for most annoying screen flickering issues... Done a substential amount of digging and finally discovered the app "Twillight" works like a charm by enabling backlight control...Just try it out with similar issues and post your review and thank me...Cheers...
So My S5 worked great for 2 months or so but then the screen started flickering at very low brightness. As time passed the flickers increased and now whenever the brightness goes below half, the screen shows yellow flickers. That's not even the biggest problem, when i lock my phone and then press the lock/home button to turn on the screen, it shows a flash on the screen and goes dark again. This takes around 15-20 tries everytime almost (sometimes even A LOT more) to turn back on.
There was no water or fall damage.
I've tried factory/hard resetting, disabling hardware acceleration, disabling google chrome (worked for some people on the internet) still not solved.
I don't have warranty, and i'm willing to pay for some repairs but can someone help me out here and tell me where exactly is the problem? Cause i really don't want to pay for a new LCD. It's kinda costly. Thank You

I have the exact same problem but only at the bottom of the screen...I am sure is not a software problem because I tried everything (from reinstaling soft with odin from4.4 to 5, with kies, to CM12/13). If you find which is the hardware please let me know.
Thank you. I also don't have warranty and i got this flicker from November.

I also have this problem. I did bring my S5 for repair under warranty (but have knox tripped) and they REFUSED to repair it,because they think the problem is caused by ME. I did go to a lawyer, and I am gonna sue them. Will update you if I have new info. I am sure it is NOT a Software problem caused by the user,I also tried changing OS,reinstalling Stock,nothing solved my problem.
any update dear as i have the same problem but for me it happened when there was low light means in darkness so when i un tick the auto brightness it will be okay no more flickering issue
Same here. Flickers, stays black. Tho I can fiddle around and it will pick up touches, and have gotten it to reboot.
It will work fine charging. Batt icon works. It only seems to be an issue while its running.
Happens on stock and cyanogen 14.
I have noticed it seems to happen more when cold.
Same problem here on cyanogen 13.0, tried factory reset to no avail. I'm about to try flashing another ROM, just need to figure ou what.
Just done wiping and reinstalling new ROM, bumped up to 7.1 and the problem is still the same.
- Screen has difficulty turning and flickers when the brightness setting is low.
I guess it must be a hardware issue.
My fix for the moment is to disable automatic brightness and never set the brightness too low, so as to avoid have trouble turning on the screen.
Same here. It's a typical problem.
Same...

I have a feeling that the problem is caused by overheating when charging. I fell asleep and woke up with the phone underneath me, it was blazing hot. It has been doing what the rest of you describe since then.
I am not 100% sure, but I've heard that it's due to the low voltage (brightness) being applied to the screen which is causing the flickering. Unsure why it's only the bottom half (Also happens on mine).
A work around for this is to install a screen-dimmer such as Darker, set the brightness on your phone to be above the flickering amount, then use Darker (or whatever app you use) to lower the brightness down.
Because Darker (or whatever app you use), is a filter, it won't change the voltage, thus no flickering.
do any of you have the always on feature enabled on the screen?
This problem is soooooooo often. Internet full of it.
Is AMOLED designed only to work for 2 years???
Anyone any information about that?
try downgrade firmware back to Android 4.0
Edit: nevermind, this didn't work
Perhaps AMOLED life time is short.
I will buy a LCD display next.
Same here only below the screen. It happened last month

How can we up to low brightness voltage? Is this possible?
It happens only at low temperatures. When you make your phone warmer, the flickering at low brightness stops.
Has anyone tried to check if some kind of cleaning the flex connector helps? I'm thinking about buying LCD sticker and give it a try.
I have the exact same problem and its related to temperature, I never face this problem in the summer.

Maybe your power button is broken?
In my A3, the screen flickers when the brightness is low. It goes away if I increase brightness. Didn't drop or do anything to phone.
Exact same problem here. I came across this post when I did a Google search to see if anyone else had the problem and it seems to be an issue that effects numerous Samsung phones, not just the A3. It also seems to be a software issue rather than an actual problem with the screen. I haven't tried this myself yet but I read that if you lower the brightness as low as you can before the screen flicker starts and then download the app screen filter and turn down the brightness further using screen filter rather than the built in control you don't get the flickering which would definitely suggest a software issue rather than hardware, particularly with multiple different Samsung models being effected. It's only really an issue for me when I get to below 5% battery and the screen automatically dims otherwise I never see it happening, it was only after reading your post that I even found I could cause it to happen by lowering the brightness. If you're someone who likes to use the very low brightness then maybe the screen filter thing would be a good workaround for you until the software issue is fixed by samsung, if they ever give us Marshmallow.
My lower half of my Samsung Galaxy A3 flickers on a low light. I read that you have to shut the phone down, take the battery out and leave it awhile before putting the battery in and starting the phone again . However, battery doesn't come out of the phone and my screen doesn't flicker on full brightness either.
Its not solved that way. I took it to Samsung and they replaced the screen now everything it good
Go to developer settings and turn on " Disable hardware overlays" . This will force GPU for screen composting.
This is a common Samsung problem, not just A3. Hardware problem. My phone is knoxed so I'm not sure I'm gonna bother contacting my operator.
Knox isn't a problem. i was rooted and had custom recovery installed yet service centre replaced the display.
As mentioned by OP, the issue is caused by a layer of the AMOLED is bent (due to pressure while in pocket or other reasons).
That is the thinnest and most bendable part of an AMOLED screen.
Only fix is replacing the screen.

It's not working .... :/abhijith.prakash
Hi. I just wanna share it. I found in this (xda comment post by some one I forget him for awhile looking for him to say thanks very much) fix for my s5 g900f with latest modem and bootloader. I use RR 7.1.2 rom.
The app is "active screen filter". That save my life.
Hello guys,
I've had the Samsung S7 Edge since august, have always cared for it (i.e. never dropped it, etc.) when all of a sudden, while I was playing Sky Force Reloaded and charging (with fast charge) when I closed the game and turned the screen off, and back on, it was crazy. The image would be flashing white and this flashing changed with the luminosity (when was full luminosity was fine). I also had AOD, and there were no problems there, the screen worked fine. This was until I restarted the phone (though it was a software problem). After the reboot the problem got worse, and I could notice different brightnesses on different parts of the screen, when I could stabilize the image, using full luminosity (and having the setting fixed. As soon as I clicked automatic brightness, It would go mad even with full luminosity).
Having the phone for such a short time, I went to the samsung responsible repair place in my city (there is no official samsung here), because they work with samsung and evaluate the warranty and fix if the defect is on them.
Well, they told me the screen was broken (there was not a single scratch on the outside, which means that only the internal LCD broke somehow), and told me It was misuse.
My question is... How is it possible to break the internal lcd without a fall, without a scratch on the outside and having it to work on some software settings? Because I don't trust this repair shop, or their technicians (they have several bad reviews involving screen defects... they always assume broken screen), and the screen replacement is not really cheap.
Thanks in advance.
I had a similar issue with mine. It was a pink line across the screen from top to bottom. I contacted Samsung via the Samsung+ app and they had me send the phone to them and they replaced the screen free of charge.
Hardware faults can happen at any time, no matter if you drop stuff or not.
Does your screen flash also in Download Mode? AOD display?
Anyway, your responsible repair place is a sh*thole... "misuse" lol.
If you're not rooted Samsung will give you a warranty repair, at least here they'd do it here at my local Samsung repair center.
