Samsung’s older flagship smartphones may soon receive a major software upgrade, as the Android 17-based One UI 9 update is reportedly reaching select Galaxy S23 series and Galaxy Z Fold 5 and Galaxy Z Flip 5 users. The rollout appears to be limited to a small group of beta programme participants in South Korea, suggesting that Samsung may be testing the stable release before making it available more widely.
The update reportedly brings new Galaxy AI features, privacy enhancements, and security tools. If the rollout expands as expected, owners of Samsung’s 2023 flagship devices could soon get access to the latest version of the company’s Android-based software.
Samsung has not been confirmed to have begun a broad global rollout for these devices based on the reported information. Availability may vary by model, region, and software programme.
Rollout
According to reports citing posts on Samsung’s Community forums and updates shared by tipster Tarun Vats, select Galaxy S23 series users in South Korea have started receiving the stable One UI 9 update. The initial release appears to be restricted to users who previously enrolled in the One UI 9 beta programme.
The reported rollout covers the Samsung Galaxy S23, Galaxy S23+, and Galaxy S23 Ultra. However, the update does not appear to be available to all owners yet.
The reported firmware version numbers for the Galaxy S23 series include S918NKSU8GZIF and S918NOKR8GZIF. These identifiers are associated with the reported release, although users should check their device’s software information to confirm the exact version available for their model.
Samsung is expected to expand availability to additional users and markets, potentially including India, in the coming weeks. However, a specific date for the wider rollout has not been confirmed in the supplied report.
Foldables
The reported update is also reaching selected Samsung Galaxy Z Fold 5 and Galaxy Z Flip 5 users enrolled in the beta programme in South Korea.
For the Galaxy Z Fold 5, the reported firmware identifiers include F946NKSU6HZIJ and F946NOKR6HZIJ. The update is said to be approximately 485.41MB in size.
The reported rollout is significant because it suggests Samsung may be preparing to bring its latest software to flagship smartphones launched in 2023. Still, the update’s availability should not be taken as confirmation that every Galaxy Z Fold 5 or Galaxy Z Flip 5 user can install it immediately.
Users outside South Korea may need to wait until Samsung begins distributing the update in their regions. Carrier requirements and device variants can also affect when an update appears.
Features
One UI 9 is based on Android 17 and reportedly introduces several additions to Samsung’s software experience. These include new Galaxy AI capabilities, updated privacy settings, and security-related features.
Reported highlights include Privacy Alerts, Security Brief, My FanCam, an expanded Galaxy AI toolkit, and Scam Detection tools. The aim is to provide users with more useful AI functions while strengthening privacy awareness and protection against potential digital threats.
Privacy Alerts are intended to help users better understand privacy-related activity, while security features can provide additional information about potential risks. Scam Detection tools are designed to help identify suspicious activity or communications.
The availability of individual features can vary by device, region, language, and software configuration. Not every Galaxy AI feature offered on newer Samsung phones will necessarily be available on older models, even after they receive One UI 9.
Timeline
Samsung reportedly began rolling out stable Android 17-based One UI 9 to the Galaxy S26 series in September 2026. The software was previously introduced alongside the Galaxy Z Fold 8 and Galaxy Z Flip 8 series in July, according to the supplied report.
The reported expansion to the Galaxy S23 series and 2023 foldables would extend the update to older flagship hardware. However, a rollout to beta participants does not necessarily mean the update is immediately available to all users.
Samsung typically distributes software updates in stages. The process can begin in selected markets before expanding to additional countries and device variants. Users should therefore avoid assuming that an update is missing from their phone simply because another person has already received it.
Installation
Galaxy S23 series, Galaxy Z Fold 5, and Galaxy Z Flip 5 owners can check their phones manually for available software updates.
Follow these steps:
- Open Settings on your Samsung phone.
- Select Software update.
- Tap Download and install.
- Follow the on-screen instructions if an update is available.
Before installing a major update, connect the phone to a stable Wi-Fi network and ensure the battery has sufficient charge. Backing up important data is also recommended.
If One UI 9 does not appear, the update may not yet have reached the device, region, or software channel. Users should avoid downloading firmware from unofficial sources, as an incorrect package can cause installation problems.
Outlook
The reported One UI 9 rollout could give Samsung Galaxy S23 series owners and Galaxy Z Fold 5 and Galaxy Z Flip 5 users access to newer Android software and updated Galaxy AI features. For now, the release appears limited to selected beta participants in South Korea, and a broader rollout has not been confirmed in the supplied report.
Owners should monitor Samsung’s official software update channels for region-specific availability and check their devices periodically. The key detail is that a reported stable release for a small group does not mean the update is already available to every compatible phone.
