Some customers and even techies are complaining that some of the Galaxy S8 and S8+ displays are currently showing a reddish tint. The red tinge issue was slowly starting to become a headache for Samsung because of all the bad PR that it was bringing to the company. They have only just started to leave the Note 7 disaster behind and move ahead, so this is definitely not something that Samsung would want to see being escalated. Samsung did mention that they will be addressing the problem with an update and they have released that update earlier today in South Korea.
The OTA update with firmware version G950NKSU1AQDG for the S8 will now add one extra setting to the phone's display section, which will give users the power to control "full screen color balance." Hopefully, this will enable users to adjust the screen until the reddish hue disappears. Additionally, another newly added option called the Screen Edge Color Balance can be used to adjust the color balance on the curved edges of the display. Samsung will most likely be releasing this update everywhere, but that isn't official news as of yet.
