The update amounts to 138MB and adds the color optimization settings that help bring the red hues down in the display settings menu. There are some stability and performance improvements sprinkled into the firmware too.
If you're not familiar with the problem, some Galaxy S8 and S8+ devices have a reddish tint to their Super AMOLED out of the box, which Samsung claims is due to "natural variation" in screens. Still Samsung promptly targeted user indignation via a software update that resolves the issue.
Lmao. I think its hardware issue (Super Amoled) issue used to has the same issue on my S7 edge pearl black 128gb white looks excellent, but still red tint is there some time even more noticeable.
Found a fix for the edges. it is in settings, display, screen mode, advanced option, screen edge color balance. Adjusted to cool, by default it is set to "balanced" between cool and warm. Unfortunately Red tint pops out really bad when in Amoled Cine...
