The launch of the device is a key step for the South Korean tech firm as it seeks to move on from last year’s humiliating withdrawal of the Galaxy Note 7 over exploding batteries, which hammered the firm’s once-stellar reputation.
The Galaxy S8 started over-the-counter sales in the US and its home market but South Korean users who per-ordered the phones complained their screens displayed an unusually reddish hue.
Online images of their phones went viral on social media but Samsung denied a hardware flaw and maintained that users could manually adjust the color range according to their preferences.
As more users voiced doubts, Samsung said Monday that a software update would fix the problem by allowing them to readjust colors over a wider range than at present.
“Samsung... has decided to release a software update starting from this week which will provide consumers with a further enhanced ability to adjust the color setting to their preference,” it said in a statement.
