Samsung’s One UI 8 Beta 4 Turns the Moon Purple – Here’s the Fix

Samsung’s latest One UI 8 Beta 4 has an unusual glitch—it’s turning the moon purple. If you’ve ever wondered what an extraterrestrial lunar landscape might look like, just zoom past 30x with Intelligent Optimization cranked up to max. The result? A surreal, violet-hued moon that definitely doesn’t match reality.

Thankfully, Samsung’s beta team is already aware of the issue. But until a fix arrives, the only workaround is dialing back Intelligent Optimization. I guess you could call this a rare “purple moon” moment—just not the kind anyone expected.

Why Is the Moon Turning Purple?

One UI 8 Beta 4 is Samsung’s newest test build based on Android 16, available for Galaxy devices enrolled in the beta program. As with any beta, bugs are expected—but this one is particularly eye-catching.

Here’s what’s happening: When you zoom in beyond 30x with Intelligent Optimization set to “Maximum,” the live preview shows the moon’s natural gray-white color. But the moment you snap the photo, AI post-processing kicks in, transforming it into a vivid purple mess while also degrading image quality.

Normally, Intelligent Optimization is supposed to enhance photos by adjusting brightness, contrast, and sharpness. On One UI 7, for example, 100x zoom shots would sharpen craters and maintain realistic tones. But in this beta, the AI seems to have gone rogue.

How to Fix It (For Now)

Beta testers in the U.S., U.K., and India have confirmed the issue on the Samsung Community forums. Since the problem occurs during processing—not in the preview—switching camera modes or disabling Scene Optimizer won’t help.

The only temporary solution? Lower Intelligent Optimization from “Maximum” to “Medium” or “Minimum.” This prevents the overzealous AI from tinting the moon an unnatural shade.

When Will Samsung Fix It?

Samsung usually rolls out three to six beta updates before a stable release. One UI 8 Beta 5 is expected next week for the Galaxy S25 series, potentially the final beta before the official launch in September. However, wider updates for other devices may take until October.

Meanwhile, Samsung has also begun testing One UI 8 Beta on the Galaxy S24 series, Z Fold 6, and Z Flip 6, with more devices joining soon. Here’s hoping the purple moon bug gets squashed before the stable release—because while a lavender moon might be fun, it’s not exactly what photographers are looking for.

Would you keep the purple moon as a quirky feature, or is this one bug that needs fixing ASAP? Let us know in the comments!
