Hello, yesterday my phone started to show some green color on the screen, it started by once, I didn't drop it or something. Few seconds it's working good, but then it returns to all green or all mixed. And when i lock my phone, it starts to become green, even when it's locked?? Tried going to safe mode, soft and master reset, nothing is working. Any ideas? Thank u guys!

Open a ticket with Samsung and send it in for a screen replacement. if there is no water damage or physical damage they will fix it for free under warranty.

Green Screen of Death :(

Very sorry to hear about it

While my S8 was messed up, my sisters s7 Edge had the exact same problem...

Now slowly, the green screen would start to flicker at times and lo one day, it would turn into a pale green light. You wont be able to do anything with the phone.

My IMMEDIATE ADVICE ...
TAKE a COMPLETE BACKUP of your data as soon as you read this message.

Secondly
Try turning the Blue Light filter off, Change the saturation of the phone and see if you are still seeing the green shade,
Send this device to service center.

EDIT :- Just now noticed the OP's date is almost a year old.

I have fixed my phone twice with this problem. You need to heat up the screen. Full brightness then record video for an hour. You should see the greenness recede. If there are green lines st the bottom which don't disappear, use a hairdryer on the screen. You will see the green vanish in 30seconds. When the phone cools, it will come back. You need to keep regularly reheating your screen to get rid of it, like every 20 minutes for a day or, 2. Eventually it will clear up. It's a pixel what issue. Heating the screen repeatedly restores functionality, after least in my case.

It is correct that it works in full brightness. Turn off the adaptive brightness and voila you can continue to work with full brightness. However, you can also reduce your
pixel to full HD from QHD to continue in this mode. I have been working on this for last few days else the ****sung care only want's to replace the screen combo .
Will try the heating methodology. I have doubts about battery also and planning to change and see.

Same issue just popped up today for me. Rooted nougat ROM with safestrap. It's definitely not the screen itself, and it's behavior is Sunday strange, it'll show up on webpages or other screens that are mostly white, but not on the dark mode applications.

so it's green on this thread and it gets less green when I open Chrome's settings on the top right.

Reboot fixes it. Until it comes back again.

Started to face this green tint issue on my S8 recently, the phone worked well for the past two years until suddenly one day this green **** happened. Never dropped the phone and never rooted it. For now rebooting the phone solves the issue, until it comes back. Till now it happened 5-6 times in a week. Rebooting fixes it and then it runs normally for sometime (or somedays) then it happens again.

Any solution?

Apparently it is a software problem, something about some screens batch that does not received well those new patches. i took my s8 g950fd at a Samsung authorized store and is was what they told me, but they don't fix it for free if it is not on warranty even though it is a Samsung software problem. I have tried to root and change roms, but it seems my cellphone does not accept root or new roms. if some one know how to help me id be grateful.

Sounds like a firmware bug* on at least some of these. Samsung tech support sucks elephant balls bad. Obviously Samsung is well aware of this issue by now.

*during a production run Samsung will substitute smaller chipsets and components as needed. This can cause erratic firmware/update behavior as the substituted components don't have the correct values and/or code. If so you're in a fubar because Samsung is unlikely to supply the needed patch at this late date.
You can try flashing the original firmware, be wary of updates. It could be a system apk update as well.

It could also be a hardware failure on a whole batch(es) of these phones.
