Galaxy s8 red screen

yes you may go to Samsung service centre or ask him

I saw some article over the internet. It seems factory defect.

go to the support section and have a live chat with support staff of Samsung. you will get the right solution. Thanks

go to settings and improve the display colours.. it is not a software or technical issue.. just general settings

Samsung knows this problem and likely will fix it with an update.
if you cannot wait until this update, you can go to sitting > display > screen mode > color balance then decrease the amount of the red light.
please tell me if that worked for you

yes.

update for this is due next week hopfully

any of you facing battery issue.
My S8+ does not stay the whole day after a full charge.

A lot of users have been facing this issue, mainly in Korea. Take it back to your seller for a replacement.
