Samsung has kicked off one of its busiest update cycles of 2026, combining a rapid expansion of the One UI 8.5 beta program with a critical April security patch fixing 47 vulnerabilities. The rollout, active between April 5 and April 12, now covers a wide range of Galaxy devicesâfrom the latest S25 lineup to older flagships like the Galaxy S23 seriesâmaking it one of the most aggressive software pushes in recent months.
The update is not just about new features. With multiple critical Android-level vulnerabilities addressed, Samsung is urging users to install the latest patch as soon as it becomes available in their region.
One UI 8.5 Beta Expands Across Galaxy Flagships and Midrange Phones
The biggest development this week is the expansion of the One UI 8.5 beta program. Samsung has now officially rolled out the first beta build for the Galaxy S23, S23+, and S23 Ultra, bringing its 2023 flagship lineup into the latest software testing cycle.
At the same time, the company released the first One UI 8.5 beta for the Galaxy A36 in markets like India, signaling that Samsung is not limiting early access to premium devices this year. This move could help accelerate adoption across both flagship and midrange segments.
Meanwhile, newer devices continue to receive frequent beta updates. The Galaxy S25, S25+, and S25 Ultra have now received their eighth One UI 8.5 beta build in select regions including India and Poland. Similarly, the Galaxy S24 series and Galaxy S25 FE have received their second beta update, showing steady progress toward a stable release.
Samsung is also preparing to expand the beta further. The Galaxy S23 FE has already appeared with its first One UI 8.5 beta build on internal test servers, suggesting a public rollout could happen as early as next week. In addition, beta community pages are now live for both the Galaxy S23 FE and Galaxy A35, hinting at imminent availability.
Reports also indicate that beta registrations have opened for foldable devices like the Galaxy Z Fold5 and Galaxy Z Flip5 in select regions, reinforcing Samsungâs plan to extend One UI 8.5 across its entire ecosystem.
New Features Include Cross-Platform File Sharing and System Fixes
One of the most talked-about additions in the One UI 8.5 beta is enhanced file sharing between Android and iOS devices. Samsung has introduced improved Quick Share functionality that enables Galaxy users to send and receive files more easily, even when interacting with iPhones.
This feature, often compared to Appleâs AirDrop, was previously limited and is now being rolled out more broadly across devices like the Galaxy S24 and S25 series. For users who frequently share files across platforms, this could become one of the most useful upgrades in recent years.
Alongside this, the beta builds include a range of improvements such as camera enhancements, Bluetooth stability fixes, and lock screen optimizations. While these updates may appear incremental, they contribute to a smoother and more refined user experience.
However, Samsung continues to position the beta program as a testing phase. Users opting in should be prepared for occasional bugs, performance issues, or app compatibility problems.
April 2026 Security Patch Fixes 47 Vulnerabilities
Beyond new features, the April 2026 security patch remains the most critical part of this rollout. Samsung has confirmed that the update fixes a total of 47 vulnerabilities, including multiple high-risk issues identified by Google and its security partners.
According to Samsungâs official security updates portal, the patch includes 14 critical Android-level fixes that could leave devices exposed to attacks if not updated. These vulnerabilities impact core system functions, making timely installation essential for user safety.
The update is being distributed across a wide range of Galaxy devices, including:
- Galaxy S26, S25, S24, and S23 series
- Galaxy Z Fold and Z Flip lineup, including newer foldables
- Midrange models like Galaxy A54, A55, and A56
Samsung has also expanded the March 2026 security patch to entry-level devices such as the Galaxy A05 and Galaxy A06 in select regions, ensuring broader protection across its portfolio.
This wide coverage reflects Samsungâs increasing focus on security, particularly as smartphones continue to store sensitive personal and financial data.
For users, installing the update is straightforward. Samsung recommends navigating to Settings, selecting Software Update, and tapping Download and Install. Ensuring sufficient battery and avoiding overheating during installation can help prevent interruptions.
With One UI 8.5 beta expanding rapidly and security updates rolling out simultaneously, Galaxy users now face a clear decision. The beta offers early access to new features, including improved cross-platform sharing, but comes with potential instability. On the other hand, the stable update delivers essential security fixes without the risks associated with beta software.
What remains clear is Samsungâs pace. The company is moving faster than usualâbringing new features to older devices, expanding beta access across categories, and prioritizing critical security fixes at scale. With more beta rollouts expected in the coming days, including for the Galaxy S23 FE and additional A-series devices, the update cycle is far from over.
