Samsung Confirms Galaxy S26 Ultra Red Tint Can Be Fixed by Software

The company says software calibration—not a hardware fault—resolves the discoloration on affected screens.

Overview

On Tuesday, August 4 Samsung posted a notice in the Samsung Members app in South Korea saying the faint reddish rectangular tint that some Galaxy S26 Ultra owners saw is caused by software calibration.
Affected phones show a rectangular reddish area near the center of the display that prompted early concern about permanent OLED damage.
Samsung is offering complimentary same‑day display calibration at official national service centers for any affected S26 Ultra regardless of warranty status.
The company is preparing an over‑the‑air software update to apply the same calibration remotely but has not provided a release timeline for that update.
The issue followed changes to the S26 Ultra display design that altered viewing characteristics, which helped explain why users feared burn‑in and why a software calibration is now the chosen remedy.
