Overview

  • One UI 8 Beta 4 on the Galaxy S25 Ultra applies an incorrect color shift during post-processing that turns images of the Moon vivid purple despite a normal preview.
  • Testers report that toggling Scene Optimizer has no effect but lowering Intelligent Optimization from Maximum to medium or minimum reliably reduces the tint.
  • Samsung’s beta team officially acknowledged the purple moon reports after users in the US, UK and India posted examples on the Samsung Community forum.
  • The bug appears at multiple zoom levels—including 10×, 20×, 30× and 100×—and affects some enrolled devices while leaving others untouched.
  • One UI 8 Beta 5 is scheduled to roll out next week and the stable One UI 8 release is expected in September, creating an opportunity to deliver a patch before broader distribution.
