Hi,
When I have low brightness the screen the screen shows black horizontal lines as if it was like an interference.. (it's very visible on 0:27 in white background)
Do not know if its a hardware or software problem but when I increase the brightness the lines disappear.

It's very annoying, anyone else experienced this?
I haven't had that issue with mine. Could be software or hardware. If you really wanna make sure just do a factory reset without restoring apps and if it comes back it's a hardware problem.
Hi, anyway to backup everything so I can test ?
I'm also having this exact problem and i only received the phone today.
Mine appears to happen more significantly straight after an unlock of the phone (from the lock screen) , it does not appear to happen as frequently when the brightness is turned up fully however.
I have factory reset the phone (without restoring ANYTHING from other accounts/backups) and this has not helped. What's interesting is this is happening during the phones initial installation/setup also.... so before I've even entered any account info , i lock the screen and then unlock and i'm presented with flickering horizontal lines which remain for about 10 seconds and then the screen eventually rights itself, so this proves that it is not a user data issue.
It's also worth noting that this does not happen every time i lock and unlock. I've tried removing expandable memory, with an without charge cable , with screen brightness set to auto and off auto , taking the sim out, auto rotation on and off and none have stopped the issue. I'm going to call my provider tomorrow to see if i can get a replacement , but if thought i'd add my 2 cents

Hi
yes occasionally it happens with lock screen... and yes with max brightness it seems not happen...
Everything on my phone works perfectly, I don't have any other issues common which are reported here but this it's so annoying :s
I think it's the auto britghtness service but I don't know how to disable it.
Can you test if in VSCO app when you change filter it happens too more strongly (like it happens to me)

I've always just disabled auto brightness using the check box labelled (auto) next to the brightness slider .....?
And I've downloaded that app and yes it's also happening when i change the filters.
I've just come off the phone with my provider (vodaphone) and ordered a replacement which is free, as i only got the phone today
I haven't found any similar threads for this same problem for the S7 specifically (at the time of writing this) , but there seems to be similar issues with some nexus devices too , which also use AMOLED screens so could just be that we're the unlucky ones and have faulty devices. If your's is in warranty i would get it replace

the problem is that I 'm not already within 14 days and I did not want to be several days ( or weeks ) without S7.
How do I know if they give me a new one or try to fix this one ?
Can you show me the links with this similar problem on nexus?
what piece of hardware is faulty ?
what is for sure this is not a software issue. is it a problem of the screen or the integrated graphic chip ?

Black Stripes on the Screen
Hi All,
I have started facing the same issue for the past couple of days. When I increase the brightness to the Fullest Maximum and Tick the Auto box, then the Black stripes on the screen disappears, but if I lower the brightness then they start appearing, the more I lower the brightness the thickness of the Stripes become heavier. Please help me someone on how to fix this issue. My phone barely one moth old. Samsung Galaxy S7 Edge.
hi did samsung change anything in the unit? how did they fix?thanks

Bad news matte, I had the same problem ... I had to put the phone under warranty and there was told they would have to change integrated graphic chip. Now the problem is gone for good

Hi there! Do they have to change the screen also or is the chipset something standalone? Just happened to me today...

Hello,
It seems we have the same problem, I will proceed with warranty.
After a month of purchasing, the brightness sensor is failing, and the screen horizontal white lines. (Image 1)
drive.google.com/ open?id= 0B2Kw-KtTnhcSSGFraExIVEZ1Qzg
Then adjust the sensor to the maximum or minimum lines become smaller. (Image 2)
And finally if I expose the sensor in the sun or in this case to bright light (Figure 3) lines on the screen disappear.

may i know what model is your affected unit? is it s7 edge color black?
same issue here on my girlfriend's s7 edge from EE. im going now to ask for a replacement. i dont bother i have insurance but i'm still curious if it is the oled related problem or other component. in my opinion as technician it's a hardware related issue. I only think about i've never meet any software /os to have that issue ever. how can a software can do that if there are lines overthere specified for drawing certain things, the stripes/lines cannot come out of nowhere
First it was the dead pixels issue on the screen on the s7 n now the screen flickering lines on s7 edge n s7 ... These are not software bugs these are serious hardware issue very disappointing samsung shame even their gorilla glass is also a lie easily scratchable screen
Finally found a complete solution here.
Works like a charm.

Yes, I have my phone 3 years and the screen has been getting more and more dim over the last few months. The bottom 7/8s of the screen is darker thsn the top 1/8.
What is black screen of death??
Plz google it.
For those who are facing this issue.
I was also facing the black screen of death issue from past 3 months.
The only way to avoid it was through rebooting the device.
And by searching web others recomended to replace the flex cable.
Solution:- guys now i am not facing this issue by keeping the brightness greater than 5/10 (>5)percent.
I have tested this persnally for 10 days and i have not faced black screen of death till then.
But when i reduce the brightness to 0% i start experiencing the black screen of death.
I dont know properly what incresing brightness does.
Permant fix can also be done by increasing the minimum brightness value. (I dont know that hiw to do). May be devs can help here.
Those who are facing black screen of death keep your minimum brightness at or above 10% that will fix it.
Will try.
What ROM?

I got the same problem with my nexus 5 too. After lowering down brightness to below half somewhere, the phone screen shuts off but the phone is still on and if i blindly drop down the status bar and increase the brightness by assuming the slider there, the screen again turns on
One thing to note that my screen does not have any dead pixels or display problem at all because I tested it. Also when the screen turns off the task that was carried out on the phone still stays i mean that when i play game at night and lower the brightness, then the screen turns off but i can hear the sound of the game running.
I have tried many roms but the problem still remains.

Try changing the rom which has this issue fixed at around 10℅ brightness.
Bcoz above 50 ℅ is. Huge for battery drain.
I am currently on santosh m 7.1.1 15/12/16 build and i am not experiencing black screen at 10℅ brightness.
Since you play at night ( night modde will also help ).

I have tried Santosh ROM it's still there, but the thing is that this problem I am having was even on the latest stock ROM (till android 6.0.1 Dec).
I don't know why it happens.
Hey guys, I sent my G4 Plus to the Moto Service Centre for the screen burn-in/retention problems. The guys there called it Screen Shadow instead.
They told me it would take a week as the display was to be changed, but I received my device back in 2 days.
Been using the device past 4-5 days and I really don't see any traces of Screen retention. I try to look very hard for it, but all the pixels look perfectly the same when the notification bar is pulled down.
I had an LGD before and I still received an LGD after the repair.
I'll let you guys no if there's any problem I face in the future.
FYI, the service centre is in Noida Sector 18, if you guys happen to live in/around Delhi.
Hey mate, I just got my Moto G4 Plus back from service center also and the problem is also fixed.
I re-locked my bootloader and sent it to repair under warranty. Their diagnostic was the same as yours, "Screen Shadow" and they replaced the whole "module" in 2 days.
They said the module is composed by display, touch module and board. They also replaced the gray edge of my device. Mine was scratched.
I'm satisfied with the service provided. I'm from Brazil BTW.
i live in Delhi and thanks for the heads up ill try this service center once I'm done with my exams
I'll repost in a week or two with an update with the screen status.
Will it cost me anything or is it covered in warranty?
Moto repair impresses me. I had my phone completely replaced, out of warranty, for only 75$. Shipped it and received the new device in 48 hours.

Nope, it won't cost a penny if device is under warranty.
After waiting for 2 weeks, I can see that the screen retention/shadow issue seems to be returning. I can see the ghost battery icons (very light though) after around 1-2 hoursof usage.
I'll be hoping the issue doesn't come back again.
Else rooting will be the only way...
I was also having screen retention issue. I just gave a try to one of the app from playstore( though i believe that an app could not cure hardware problems.) But it actually works. They recommend to use app for 8 hours but i used it for only one and half hour. For now there is no screen retention. You can see in the below screenshot, earlier there were impressions of data and wifi signals but now they are gone.

If you've rooted, you could use the Elemental X kernel and modify the max RGB values for the display. I think that worked for many people.

Yeah that could also be the solution but this seems to work better.
Hopefully it doesn't burn the screen evenly to create a false impression ?
I used blue light filter before the repair, but had to increase the filter from 5 to 15% as the problem worsened later.
Yep, I have all the RGB values set at 240 and no more screen retention.
If i relock my bootloader and give it for repairing, they will replace it ?
They will get to know that my phone was rooted before?

That is not working for me anymore.. it just reduce the amount of burn in..
adjusting rgb values in live display works fine for me in lineage based roms for me..

Does adjusting RGB values remove it permanently (till they are set at 240) ?
And relocking the bootloader and giving for repair depends on the Technical level of the service centre. But most probably they won't take it.
Here is my experience.
I had no screen shadow or burn in on stock for more than 6 months. I decided to root the phone and bam I got the screen shadow. I had to set RGB colors to 91% each or 233 of 256 and that works every time (EX kernel). Any higher and I'd see very light screen retention.
I had some battery issues recently and wanted to test stock kernel again to see if it is kernel related. So I went back to stock without locking the bootloader also in the hopes that it would fix the screen retention. The screen retention is still there.
I am using two apps from PlayStore to fix it on stock:
ScreenAdjuster and Bluelight filter for eye Care. They both work and I like the ScreenAdjuster better. Can't really tell there is a difference in contrast while for the latter (Bluelight) there is a small tint. Set all the values to 5% and have it start on boot. (For Bluelight you need to set it to 6%and pick the dark grey). Then hide either app from notifications and menu. Use only one of these of course.
The screen retention with any of these tricks will go away after about 10-15 min or reboot.
Before my warranty runs out in October, I will lock the bootloader and try to get it repaired.
PS: my battery performance is only slightly better on stock and I will probably go back to Invicta soon. I miss substratum.
Edit: kunalgupta1, anytime the values go back to default, the screen retention comes back over a few minutes. As long as it is set to 233 it will be gone.
Cheers

Read above. Set all three RGB values to 5% and make sure it starts on boot. It may take a few minutes for the retention to go away.

My c5 recently got a problem when I restarted my device. Its screen got dimmer then before. Its brightness control is working but screen brightness at low level is too low that one could barely see. And at higher level it isn't bright then before. As brightness is decreased from a higher level it starts to get a pink or reddish tint which gets higher at lower level with to much dark display.
What problem could it be? Is it a hardware issue or software one?

Try flashing the stock firmware, if it doesn't fix this then it is probably a hardware problem.

I factory reset it but it haven't worked for me. So still should I reinstall a stock rom using the odin method??

Same problem. I think is hardware problem. After around week in full power off state, screen again works normal few days and again get problem. And after few day working with bad brightness screen fully not working (after reboot) and need week in turnoff to return working.
I have a N986U1 with unlocked bootloader running stock One 3.1 UI. I cannot get my adaptive brightness work properly. I have to turn it off and back on before it'll be the correct brightness. It did this with One 3.0 UI too, but I believe it was working properly before unlocking bootloader. Is there a workaround? TIA

I do not think that this issue is caused by unlocking the bootloader.
Hopefully it will be fixed in next firmware updates.
Here is a thread about brightness issues for your device:
