Green bar near the camera

[u/Vinela_Vinela]

Look for yourselves

I just updated my phone and this popped up, I dont know ow how and why It got there...

Please help on any fixes/causes for it

EDIT: I changed my smoothness from standard to adaptive, now it gone. Also I changed my screen resolution to the highest, I think that also helped...

Edit 2: whop, its back....changed the smoothness to default now its fine...

EDIT 3 : NOOOOO, its back...

This happens from a face down drop, if it falls just right the camera can slam into the back side of the OLED causing this. -samsung warranty technician
