If there is any flaw with the $700+ flagship from Samsung then it would be the slightly red tinted display. Samsung promised that they would release a patch update to fix it soon. Last week in South Korea, the OTA went live but now its available for other S8 and S8+ users too. Its an 138 MB update aimed to fix the colour issues. It basically adds two option to tweak the colour. But if the user is not satisfied then they will replace the phone.
