I'm thinking your display is shot.

The good news is I don't think it's the screen. I think you might have fried some of the circuitry in the GPU, meaning that you need a new motherboard.

I'm tentatively assuming your display is still OK, just going by your posted video, and agree that it would be more likely to be some component, like the GPU, overheated and will probably fail sooner rather than later. But if the display is the problem I wouldn't be too surprised.

Whatever the issue is though, be sure you back up all your saved data while you can still use your phone. How long have you had your S8? Any chance there's still any warranty coverage?

thanks for the info , but sadly motherboard costs more than the display and its out of warranty .huawei powerbank is shit .Never will i ever use a powerbank for samsung.

So its either the display or motherboard ? I'm pretty disappointed with samsung , i didnt drop my phone all i did was use a powerbank and my screen/gpu is damaged .Yes i did Backup my phone,SideSync App is quite handy .i've had it for year and a half so its Out of warranty

I don't know that I'd blame the powerbank. The phone is supposed to regulate the current it draws, but Samsung doesn't have a good history with that. I'd keep an eye on the phone temperature for a while. If it got hot enough to damage itself, it might not be safe to leave unattended while charging.

I understand this is a really frustrating situation but at this point I don't think you should jump to any conclusions. Could be a fault with the powerbank, or the phone, or even the cable (a short in the wiring or plug). Or there may be some kind of situation that triggered a component to just fail -- i.e. if the phone was sitting on a blanket the whole time that could have resulted in an accumulation of too much built up heat (a blanket being an insulator, not a conductor of heat).

The same green flicker happened with my former S8 as well after 1 year of usage.

I though the S8 would carry me at least for 2 or even 3 years. The phone was also getting extremely hot after 5 to 6 months especially when am on the internet.

It's really a huge disappointment, do any of you know more durable quality smart phones? How about iPhone 10 and 11 ?
