The cause of the "red blotch" phenomenon on the Samsung Electronics Galaxy S26 Ultra display 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 in the center of the Galaxy S26 Ultra screen. After Samsung Electronics collected display units and other samples for examination, it concluded that the issue was due to software optimization, not a display hardware problem.
The "privacy display," first applied to the Galaxy S26 Ultra, uses "LED 2.0" technology that removes the polarizer from the organic light-emitting diode (OLED) to improve color transmittance and power efficiency, and it was found that exposure to strong light at maximum brightness causes changes in color balance. A Samsung Electronics official explained, "Because it is not a hardware issue, the problem is resolved by carrying out color-correction software optimization."
Samsung Electronics is providing a software update to users who visit service centers for this issue. For users who have difficulty visiting a service center, it plans to distribute a software update.
