The cause of the "red blotch" phenomenon occurring on the Galaxy S26 Ultra display from Samsung Electronics was found to be a software issue.
Samsung Electronics said on the 16th that the cause of the Galaxy S26 Ultra's display issue is "software optimization, not hardware," adding that it "plans to resolve it by providing an optimization update."
Earlier, users reported a red, rectangular blotch appearing near the center of the Galaxy S26 Ultra screen. In response, Samsung Electronics collected display units such as floor models for inspection and concluded that the issue stems from software optimization, not the display hardware.
The "privacy display," introduced for the first time on the Galaxy S26 Ultra, applies "LEAD 2.0" technology that removes the polarizing plate from the organic light-emitting diode (OLED) to improve color transmittance and power efficiency, and it was found that when exposed to strong lighting at maximum brightness, changes in color balance occur. A Samsung Electronics official explained, "Because it is not a hardware problem, the issue can be resolved by carrying out software optimization for color calibration."
Samsung Electronics is carrying out a software update for users who visit service centers due to this issue. For users who find it difficult to visit a service center, it plans to distribute a software update.
