With pixel-level modifications, the new display prevents shoulder surfers from ogling at your phone’s screen unless you want them to. While the feature works flawlessly, it has led to some qualitative setbacks for the display, according to some users. One that was widely echoed was the eye strain and visibility issues caused by the display changes at the microscopic level, which forced early adopters to return their units. And now, Galaxy S26 Ultra users are encountering another unpleasant display issue.Many user reports on Reddit and the Korean social media platform Naver highlight that the S26 Ultra’s displays are slowly picking up a red tint, rendering hues differently from when the phone was bought. Reports span the past few months, starting in March — just weeks after the phone’s launch — and continue to this day.
