Samsung Accelerates One UI 8.5 Testing Across Flagship and Midrange Devices
Samsung’s software rollout strategy is entering a decisive phase as multiple Galaxy devices—including the Galaxy S23 series, Galaxy Z Flip5, Galaxy A36, and Galaxy A35—receive the second One UI 8.5 beta update. The move signals an intensified push toward refining the user experience ahead of a broader stable release.
Rather than introducing sweeping new features, this latest beta iteration focuses heavily on performance stability, bug fixes, and usability improvements, a typical pattern as Samsung edges closer to final deployment.
A Broad Rollout Across Key Galaxy Devices
The second beta wave covers a diverse portfolio, reflecting Samsung’s effort to unify software quality across both premium and midrange segments.
According to the update rollout:
- The Galaxy S23, S23+, and S23 Ultra are receiving the update in India and South Korea, with firmware versions ending in ZZDP and a download size exceeding 700MB.
- The Galaxy Z Flip5 is getting its update in South Korea, carrying firmware F731NKSU6ZZDN and weighing around 760MB.
- The Galaxy A36 beta is rolling out in India with firmware A366EXXU8ZZD7, requiring roughly 650MB.
- The Galaxy A35 update is also live in India, exceeding 1GB in size with firmware A356EXXU9ZZD9.
All updates include the April 2026 security patch, aligning with Samsung’s broader push to address vulnerabilities and maintain device security.
What’s New: Focus on Stability and Real-World Fixes
Galaxy S23 Series: Refining Core Performance
For Samsung’s 2023 flagship lineup, the update zeroes in on fixing persistent issues reported by users:
- Improved incoming call screen behavior, addressing delays and black screen glitches
- Better proximity sensor handling during calls
- Fixes for green line artifacts in 4K HDR video recording
- Resolution of Bluetooth crashes
- Improvements to multi-touch responsiveness, particularly after accessibility adjustments
These fixes are particularly important for a device family that remains widely used globally, thanks to its flagship-grade hardware, including a 200MP camera system and high-performance chipset.
Galaxy Z Flip5: Polishing the Foldable Experience
Samsung’s foldable lineup continues to receive targeted improvements:
- Enhanced speaker call volume and in-car audio clarity
- Improved contact display information during incoming calls
- Added brief pop-up notifications even when the screen is off
- Fixes for screen transition issues after saving contacts
- Stability improvements for the Camera app
These updates highlight Samsung’s focus on optimizing usability in foldable devices, where interface fluidity and real-time responsiveness are critical.
Galaxy A36 and A35: Midrange Gets Meaningful Upgrades
Samsung is extending its beta improvements to midrange users, ensuring software parity across price segments.
Both the Galaxy A36 and A35 receive similar fixes:
- Bluetooth Autoscan issues resolved
- Improved Quick Panel responsiveness
- Fixes for message input overlap with navigation bar
- Resolution of System UI ANR (App Not Responding) issues after FOTA updates
This consistency reflects a broader strategy: premium-level software reliability is no longer exclusive to flagship devices.
Context: A Larger Beta Expansion Strategy
This update is part of a wider One UI 8.5 testing phase across Samsung’s ecosystem. The company has been actively expanding beta programs to multiple devices, including foldables, Fan Edition models, and tablets.
Notably:
- The Galaxy S23 lineup and Z Flip5 are among devices receiving Beta 2 in select regions
- Several Galaxy A-series models are also included in testing
- The updates largely focus on bug fixes, smoother performance, and pre-release refinement
At the same time, the anticipated stable One UI 8.5 rollout for the Galaxy S25 series has faced delays, underscoring the importance of thorough beta testing before wider deployment.
Why This Update Matters
1. Stability Over Features
This beta cycle emphasizes software maturity rather than innovation. By addressing bugs across calls, camera, Bluetooth, and UI responsiveness, Samsung is prioritizing everyday reliability.
2. Unified Ecosystem Experience
From flagship devices like the S23 Ultra to budget-friendly A-series models, Samsung is ensuring a consistent software experience across its lineup.
3. Preparing for Stable Release
Beta 2 updates typically indicate that a stable rollout is approaching, though timelines may vary by region and device category.
How to Access the Update
For users enrolled in the beta program, the update can be installed manually by navigating to:
Settings → Software update → Download and install
The Road Ahead for One UI 8.5
Samsung’s aggressive beta expansion suggests that One UI 8.5 is entering its final refinement stage. However, delays in stable releases for newer devices indicate that the company is taking a cautious approach.
Looking forward:
- More beta iterations may follow to address remaining edge cases
- Stable rollout could begin gradually across regions
- Continued focus on security patches and performance optimization will likely remain central
Conclusion
The second One UI 8.5 beta update marks a critical step in Samsung’s software evolution. Rather than chasing headline features, the company is focusing on eliminating friction points that affect everyday use.
By extending these improvements across flagship, foldable, and midrange devices, Samsung is reinforcing its commitment to delivering a polished, reliable Android experience at scale—a move that could strengthen its competitive position as software quality becomes increasingly decisive in the smartphone market.
