Hey @LeeYon ,

that doesn't seem right to us. Is this happening with a game in particular? Does this affects any other apps and is the phone only overheating when you play games?

Hi.

There's no app in particular. It also happens in home screen. Maybe in other apps but not that noticable unlike when I am playing. 

The flickering started few days ago. maybe 2 or 3. The green display happened after reset. It is green even when the charging while the phone is off.

Are you able to share a screenshot or a video of this here? Can you try your phone in Safe Mode? Using Safe Mode on a Samsung phone or tablet allows you to force the device to run the essential operating system, and disable most 3rd party applications. It's designed as a diagnostic tool to help solve issues with connectivity, battery life, apps, and more. To do this press and hold the Power button until you see Power Off, Restart and Emergency. Press and hold the Power Off icon until it shows a Shield, tap the Shield and the device will restart in Safe Mode. Once done, monitor the device for two hours to see if the issue persists.
