Galaxy S23 Ultra One UI 8.5 Update: Uncovering the Missing Features and Omissions

Samsung has officially begun the global rollout of the stable One UI 8.5 update, bringing a wave of fresh enhancements to its flagship lineup. While the Galaxy S23 Ultra is among the elite devices receiving this firmware, many users are discovering that the experience isn't quite identical to that of the newer Galaxy S25 or S26 series. Despite Samsung's reputation for long-term software support, certain "cutting-edge" features seem to have been left on the cutting room floor for this 2023 powerhouse.

The Reality of Software Fragmentation in Newer One UI Versions

It is a common trend in the mobile industry: a new software version arrives, but the "hero features" remain exclusive to the latest hardware. For owners of the One UI 8.5 update on the Galaxy S23 Ultra, this reality is setting in. While the core stability and UI refinements are present, the gap between the S23 Ultra and the S25 series is becoming more apparent, specifically within the Galaxy AI suite.

Samsung often cites hardware limitations—such as NPU (Neural Processing Unit) performance or RAM constraints—as the reason for these omissions. However, considering the raw power of the Snapdragon 8 Gen 2 inside the S23 Ultra, some fans argue that these are deliberate choices to encourage upgrading to newer models.

Specific Galaxy AI Tools Missing from the S23 Ultra

One of the most noticeable absences is within the "Call Assist" feature. While the S23 Ultra supports basic AI assistance, it completely misses out on the sophisticated new call screening capabilities seen in the Galaxy S25. This feature allows the AI to handle calls with much higher nuance, a tool many users were looking forward to.

The "Photo Assist" gallery tool has also been trimmed down. Specifically, the "Create" tab is missing the text icon, and the "Style" tab—which allows users to transform photos into artistic watercolor or sketch styles—is nowhere to be found. These creative AI edits are currently reserved for the latest generation of Samsung devices.

The Missing Audio Eraser and Video Enhancements

Perhaps the most frustrating omission for content creators is the "Audio Eraser." This tool, designed to remove background noise or specific sounds from recorded videos, has been a highlight of Samsung's recent AI marketing. Unfortunately, despite the S23 Ultra having more than enough processing power for high-end video editing, this feature has been excluded from its version of One UI 8.5.

To see a side-by-side comparison of what is present and what is missing, you can watch the detailed breakdown by our colleagues. It provides a comprehensive look at the firmware differences that might impact your daily usage.

Does the Galaxy S23 Ultra support the new One UI 8.5 update?

Yes, Samsung has released the stable One UI 8.5 update for the Galaxy S23 Ultra, and it is currently rolling out in most global markets.

Is the AI Call Screening feature available on the S23 Ultra?

No. While the S23 Ultra has "Call Assist," it lacks the advanced call screening capabilities found on the newer Galaxy S25 and S26 models.

Can I use the Watercolor photo style on the S23 Ultra?

Currently, the "Style" tab for Galaxy AI photo edits, including the watercolor effect, is missing from the S23 Ultra's One UI 8.5 firmware.

Why did Samsung exclude the Audio Eraser from this model?

Samsung has not provided a specific technical reason, but it is likely due to a combination of hardware optimization focus for newer chips and maintaining feature exclusivity for the latest flagship series.

Will these missing features be added in a future patch?

While Samsung occasionally backports features in smaller "x.1.1" or security updates, there is no official confirmation that these specific AI tools will ever come to the S23 Ultra.

🔎 While the One UI 8.5 update remains a vital and welcome improvement for the Galaxy S23 Ultra, the omission of several key Galaxy AI features serves as a reminder of the inevitable march of technology. The S23 Ultra remains one of the most capable smartphones on the market, yet it is clear that Samsung is beginning to draw a line between its "legacy" flagships and the new era of AI-first devices. For most users, the update is still worth installing for the security and UI refinements, even if the most futuristic tools remain just out of reach.
