Samsung’s OneUI 8.5 Beta 4 update is rolling out to Galaxy S25 series devices ahead of the Galaxy S26 launch — and while it mainly focuses on bug fixes and stability updates, teardowns and leaks have uncovered several hidden features and quality‑of‑life improvements that users may not notice at first.
🔍 1. Direct Voicemail With Live Transcripts
A subtle but useful addition in Beta 4 is Direct Voicemail — the ability to send calls straight to voicemail and view live transcribed messages inside the Phone app. This can be helpful for quickly checking voicemail content without listening to audio.
🛠️ 2. Bug Fixes That Improve Core Functions
Although not advertised as new “features,” Beta 4 includes hidden refinements that improve everyday usability:
-
Fixes for search history glitches in the Phone app and smoother Bluetooth call handoffs.
-
Phone app behavior improvements such as proper handling of pasted numbers after tapping call links.
-
Better behaviour from the AI Select tool so it closes promptly after copying content.
📸 3. Camera Feature Access Changes
Earlier OneUI 8.5 beta builds brought back niche camera functions like Single Take and Dual Rec (which were missing in an earlier beta), but these are now tucked away inside Samsung’s Camera Assistant app rather than visible in the main camera modes — a hidden change that advanced users may want to explore.
🌐 4. Hidden UI and Visual Tweaks
Leaks and test builds have hinted at additional visual or interface refinements that may not be obvious straight away:
-
Expanded blur effects across panels for a more premium look.
-
Customized Quick Settings rearrangement and independent sliders for brightness/volume.
-
Lock screen weather animations that match real‑world conditions.
-
Improved Now Bar functionality with alarm support.
-
Hidden gallery features like Private Album access and improved browsing.
🛡️ 5. Privacy‑Focused Enhancements
Code leaks suggest OneUI 8.5 may include a Privacy Display feature that limits screen visibility from side angles — useful in public places — and expand privacy tools such as auto‑blurring sensitive photo data when sharing (likely using on‑device AI). These enhancements focus on subtle protection rather than headline‑grabbing UI changes.
📌 What’s Still Missing (But Expected Later)
Some of the most talked‑about features — such as AI‑powered notification summaries — are not currently present in Beta 4 and may be held back for the official OneUI 8.5 launch tied to the Galaxy S26 launch event.
In summary: Beta 4 of OneUI 8.5 isn’t a dramatic overhaul, but it hides meaningful refinements that enhance daily use — from smoother telephony behavior and voicemail tools to camera access tweaks, visual polish, and expanded privacy options. These subtle improvements, combined with behind‑the‑scenes AI and interface changes, show Samsung preparing OneUI 8.5 for a polished public release later this year.
