Red Glow Explained: Night Mode Makes Your Galaxy Watch Ultra Readable in the Dark
Your Galaxy Watch Ultra’s red display isn’t a defect—it’s Night Mode automatically triggering in low light to boost readability. The red glow works only on the Ultra’s Simple Ultra and Ultra Analog faces and can auto-toggle with ambient light. To stop the red glow, customize the watch face and set Night mode to Off (or stay red by keeping Night mode On for a constant glow). This feature is exclusive to the Ultra model.
