Samsung One UI 8.5 Update: Galaxy S23, A56, Tab S11 and More
is speeding up the release of its Android 16-based One UI 8.5 update for more Galaxy phones and tablets. The update first came with the Galaxy S26 series in early 2026 and became stable for more devices in South Korea earlier this month. Last week, the Galaxy S25 series got the update in India and the US. Now, users on X are reporting that the update is reaching the Galaxy S23 series, some tablets, and mid-range Galaxy A models.
The update reaching the Galaxy S23 series is a big deal. The S23 came out in early 2023, so getting Android 16 now shows Samsung is keeping its promise of 7 years of updates. Samsung is delivering Android 16 to a three-year-old flagship before many competitors have updated their 2024 models. This highlights the value of Samsung's long-term software support, which also applies to the Galaxy S26 Ultra and Galaxy Z Flip 8.
One UI 8.5 Rollout Timeline and Scope
Samsung is rolling out One UI 8.5 in phases. The stable update started in South Korea this month after the Galaxy S26 launch. Last week, India and the US got the update for the Galaxy S25 series. Now, the update is reaching the Galaxy S23 series in India, the Galaxy Tab S11 family, the Galaxy Tab S10 FE in Korea, and the mid-range Galaxy A56 and A36 models.
Samsung usually rolls out major Android updates in phases. They start with the newest flagship, then move to the previous flagship, and finally to older and mid-range models. Including the Galaxy A56 and A36 with the S23 series in this wave shows Samsung is speeding up the One UI 8.5 update for all price ranges, not just flagships.

Samsung is also updating the Galaxy A56 and A36, two popular mid-range phones, in markets like India. Adding these A-series models to the same rollout as the Galaxy S23 shows Samsung is working fast to bring the Android 16 update to more devices, not just premium ones.
For Galaxy A56 and A36 users, One UI 8.5 brings Android 16 and all of Samsung's Galaxy AI features. These tools first appeared on the Galaxy S26 Ultra, and now mid-range users are getting them just months after the flagship launch.
What Is New in One UI 8.5
One UI 8.5 includes several Galaxy AI features introduced with the Galaxy S26 series, now expanding to eligible older devices. The key new additions include:
Call Screening
Call Screening uses Galaxy AI to check incoming calls and block possible spam or unwanted calls before they reach you. It can answer for you, ask the caller a question, and show you a transcript of their reply so you can decide if you want to take the call. This helps cut down on spam calls without you having to deal with unknown numbers.
Agentic AI Tools
Agentic AI means the AI can do tasks for you on its own, not just answer one question at a time. In One UI 8.5, these tools can handle several steps in a row, like booking a restaurant, writing and sending a message, or searching for info and acting on it, all without you having to do each step yourself.
Creative Studio
Creative Studio is Samsung's AI tool for making and editing images, applying art styles, and creating visual content using both on-device and cloud AI. It supports continuous AI image generation, so you can keep changing your images and see updates in real time instead of waiting for each version to finish before making more changes.
Improved Audio Eraser
Audio Eraser is a Galaxy AI feature that removes unwanted background sounds from your video recordings, like wind or crowd noise, while keeping the main audio clear. One UI 8.5 makes this tool more accurate and able to handle more types of background noise.

Final Verdict
The wider rollout of One UI 8.5 shows Samsung is keeping its promise of 7 years of software updates, which benefits Galaxy owners. People who bought a Galaxy S23 in 2023 are now getting Android 16 in 2026, three versions after launch, along with all the Galaxy AI features from the S26 flagship. This kind of update is a big reason why Samsung charges more for its flagship phones.
For Galaxy A series users, One UI 8.5 brings AI features that used to be only for flagship phones, just months after they first appeared. Call Screening, Agentic AI tools, Creative Studio, and the improved Audio Eraser are all big upgrades that make everyday use better, not just small changes.
Because the update is rolling out in phases, some regions and device models will get it before others. If you have not seen a notification yet, check manually and keep checking over the next few days as Samsung expands the rollout.
Bottom line: If you have a Galaxy S23, S24, A56, A36, Tab S11, or Tab S10 FE, go to Settings > then Software Update > and tap Download and Install. The One UI 8.5 update with Android 16 and Galaxy AI features like Call Screening and Creative Studio is rolling out now.

5. What is Call Screening in One UI 8.5?
Call Screening is a new Galaxy AI feature in One UI 8.5 that uses AI to handle unknown or potential spam calls on the user's behalf. When an unknown caller rings, Call Screening can answer the call, present the caller with a question prompting them to identify themselves or their purpose, transcribe the caller's spoken response in real time, and display the transcript to the user so they can decide whether to join the call or decline it. This reduces interruptions from spam calls while giving the user enough information to make an informed decision without having to answer unknown calls directly.
6. What are Agentic AI tools in One UI 8.5?
Agentic AI tools in One UI 8.5 refer to AI features that can autonomously execute multi-step tasks on behalf of the user rather than responding to a single command. Unlike standard AI assistants that answer one question at a time, agentic AI can chain together multiple actions, such as searching for a restaurant, checking availability, composing a booking request, and sending a confirmation message as a single connected workflow initiated by one user instruction. This is a more capable, autonomous form of AI assistance that reduces the number of manual steps required for complex tasks.
7. What does Creative Studio do in One UI 8.5?
Creative Studio is Samsung's Galaxy AI feature for generating and editing images using AI. It allows users to create original images from text prompts, apply artistic style transformations to existing photos, and iterate on generated content through continuous AI image generation, where changes appear in a flowing, real-time process rather than requiring a full regeneration for each adjustment. Creative Studio is aimed at users who want to create social media content, explore artistic edits, or generate custom visual material without requiring professional design skills or third-party applications.
8. Will the Galaxy S22 get the One UI 8.5 update?
Samsung has not confirmed the availability of One UI 8.5 for the Galaxy S22 series in its current rollout information. The Galaxy S22 series falls outside Samsung's 7-year OS update commitment, which began with the Galaxy S24 series. Samsung is committed to 7 years of OS updates for Galaxy S24 and newer devices. The Galaxy S23 series is receiving One UI 8.5 as part of its update cycle, but the Galaxy S22 may have reached the end of its guaranteed major Android OS updates. Checking Samsung's official software update page for the Galaxy S22 on the Samsung India website will provide the most accurate information about whether the S22 is included in any future One UI 8.5 expansion.
9. How large is the One UI 8.5 update file?
The One UI 8.5 update size varies by device. For the Galaxy S23 series, the update is reported at approximately 4GB. For the Galaxy Tab S10 FE, the update is approximately 2.8GB. The size reflects the full Android 16 OS update combined with the One UI 8.5 feature layer. A 4GB download requires a stable Wi-Fi connection and can take 15 to 30 minutes, depending on connection speed. Samsung recommends not using mobile data for a download this size and keeping the device plugged in during the installation process, which can take 5 to 15 minutes after the download completes.
10. What happened to One UI 8, and will my device get it before One UI 8.5?
One UI 8 was Samsung's previous Android update and has already been distributed to Galaxy devices ahead of One UI 8.5. One UI 8.5 is a significant feature update rather than a separate software generation, built on Android 16 and adding the Galaxy AI features that debuted with the Galaxy S26 series. Devices that received One UI 8 will receive One UI 8.5 as an update rather than needing a separate One UI 8 installation before One UI 8.5. If your device has received One UI 8 and is on Samsung's eligible list for One UI 8.5, you can check for the One UI 8.5 update directly in Settings > Software Update,, without needing any intermediate version.
