Bringing the latest software to as many phones as feasible
In the ongoing negotiation between technological progress and economic accessibility, Samsung is extending its One UI 9 operating system to the mid-range and budget Galaxy devices that most of its global users actually carry. This expansion — methodical, selective, and still unfolding — reflects a quiet but consequential commitment: that the benefits of new software need not belong only to those who can afford flagship hardware. The boundary conditions of this generosity, however, remain real, as certain older and less capable models will be left behind, a reminder that inclusion in the digital age is always partial.
- Samsung is pushing One UI 9 beyond its flagship walls, initiating compatibility testing on Galaxy M and A series phones that serve the majority of its global user base.
- The expansion is not universal — select Galaxy S and A models have been quietly cut from the upgrade path, creating a fault line between supported and abandoned devices.
- Engineering resources are actively being directed toward mid-tier models like the Galaxy M56 and M35, signaling that stability testing is serious and the rollout timeline is real.
- Samsung's Good Lock platform is being updated in parallel, with LockStar and NavStar gaining One UI 9 support and Galaxy Flip devices receiving new cover screen unlock animations.
- The current testing phase positions Samsung for a broad, multi-tier launch later in the year, aiming to deliver meaningful software longevity to users across economic segments.
Samsung is methodically widening the reach of its One UI 9 operating system, moving beyond the flagship Galaxy S phones that traditionally receive updates first. The company has begun compatibility testing on Galaxy M-series and A-series devices — the mid-range and budget phones that represent the bulk of its worldwide installed base. Models like the Galaxy M56 and M35 are already in development for One UI 9 support, a signal that Samsung is investing engineering resources in feature parity across economic tiers, not just at the premium end.
The expansion is selective, not universal. Certain Galaxy S and A models have been excluded from the One UI 9 upgrade path, a standard industry practice that reflects the reality of hardware limitations — older or underpowered devices can be degraded rather than improved by newer software. The line between supported and unsupported devices is a quiet but meaningful one for millions of users.
Alongside the core OS rollout, Samsung is updating its Good Lock customization platform for One UI 9 compatibility. LockStar and NavStar — tools governing lock screen personalization and navigation gestures — are both receiving support, while Galaxy Flip owners will gain new cover screen unlock animations that leverage the foldable form factor.
The timing places Samsung on track for a broad, multi-tier launch later in the year. By testing across device categories now, the company is positioning One UI 9 as a genuinely inclusive update — one that extends software longevity and modern features to users who chose capability over cost.
Samsung is methodically expanding its One UI 9 operating system beyond the flagship Galaxy S phones that typically get first access to major updates. The company has begun testing the new software on Galaxy M-series and Galaxy A-series devices—the mid-range and budget phones that make up a substantial portion of Samsung's installed base worldwide. This expansion means millions of additional users could eventually receive the update, though the rollout will be selective and phased.
The testing phase is already underway for specific models. The Galaxy M56 and Galaxy M35 are among the devices currently in development for One UI 9 compatibility, according to Samsung's internal timelines. These are not flagship devices; they occupy the middle tier of Samsung's portfolio, aimed at users who want a capable phone without flagship pricing. The fact that Samsung is dedicating engineering resources to bring One UI 9 to these models signals confidence in the update's stability and a commitment to spreading new features across a wider economic range of consumers.
However, the expansion comes with a clear boundary. Not every Galaxy S or Galaxy A phone will make the cut. Some popular models in both lineups have been excluded from the One UI 9 upgrade path, likely due to hardware limitations or Samsung's strategic decision to reserve the update for devices with sufficient processing power and RAM to run it smoothly. This selective approach is standard practice in the industry—older or less capable devices can become sluggish when forced to run newer software, degrading the user experience rather than improving it.
Beyond the core operating system rollout, Samsung is also enhancing its Good Lock customization platform to support One UI 9. Two specific tools—LockStar and NavStar—are receiving One UI 9 compatibility updates. LockStar allows users to customize their lock screen experience, while NavStar handles navigation and gesture controls. For Galaxy Flip users, Samsung is introducing new cover screen unlock animations, a feature that takes advantage of the unique form factor of its foldable devices. These additions suggest that One UI 9 will bring meaningful visual and functional refinements, not just under-the-hood improvements.
The timing of this expansion is significant. Samsung typically announces its major operating system updates in the summer, with broader rollouts following in the fall and winter months. By testing One UI 9 across multiple device tiers now, Samsung is positioning itself to launch the update to a genuinely broad audience when it becomes official. The company's strategy appears to be one of inclusion—bringing the latest software to as many phones as feasible while maintaining quality standards for devices that can actually benefit from the upgrade. For Galaxy owners in the mid-range segment, this expansion represents a meaningful commitment to software longevity and feature parity with more expensive models.
The Hearth Conversation Another angle on the story
Why does Samsung bother testing One UI 9 on mid-range phones like the M35? Wouldn't it be simpler to just focus on flagships?
Because mid-range phones are where the volume is. Millions more people own a Galaxy M or A than own a Galaxy S. If Samsung only updated flagships, it would be leaving the majority of its users behind.
But the article says some popular Galaxy S and A phones won't get the update. How do they decide which ones qualify?
It comes down to hardware. A phone needs enough processing power and memory to run One UI 9 without becoming sluggish. Older devices or those with weaker chips simply can't handle it smoothly. Samsung would rather exclude a phone than ship a bad experience.
What about the Good Lock updates—LockStar and NavStar? Are those just cosmetic?
Not entirely. LockStar lets you redesign your lock screen, and NavStar controls how you navigate the phone. Those aren't trivial. And for Flip users, new unlock animations on the cover screen—that's actually useful because the cover screen is how you interact with the phone when it's folded.
So One UI 9 feels like a genuine upgrade, not just a version number bump?
From what's being tested, yes. It's not revolutionary, but it's thoughtful. New features on the lock screen, better customization, foldable-specific improvements. It's the kind of update that makes people feel like their phone got better, not just different.
