One UI 9 Beta: Subtle Changes, Big Control Gains
The One UI 9 beta is shaping up to be a meaningful refinement rather than a radical redesign, and its most interesting upgrades sit at the intersection of interface and security. Beyond headline additions like expanded Quick Panel customization and new text spotlighting tools, Samsung is quietly targeting long-standing pain points for everyday Galaxy phone users. Two of the most notable tweaks are a new option to hide app handles in split-screen view and a dedicated menu that collects all sideloaded apps in one place. On the surface, these sound like minor preferences toggles. In practice, they reshape how people manage multitasking and Galaxy phone security, placing more emphasis on user awareness and control. Together, they show Samsung using One UI 9 not just to polish visuals, but to streamline split-screen view customization while tightening oversight of software installed outside official stores.
Cleaning Up Multitasking: Hiding App Handles in Split-Screen
Multi Window mode has long been a productivity staple on Galaxy phones, allowing two apps to run side by side with a draggable bar dividing them. In previous versions such as One UI 8.5, that experience was cluttered by persistent app handles at the top of each window. These icons are useful—they let you swap apps, pop them out, maximize, or close them—but they were always visible and impossible to hide. One UI 9’s beta changes that with a new toggle in Settings > Advanced features > Multi window. Users can now choose whether app handles appear while multitasking. For those who found them distracting or visually intrusive, this split-screen view customization makes the interface cleaner without sacrificing functionality, since the handles can be re-enabled at any time. It is a small tweak that underlines a wider philosophy: letting users decide how busy or minimal their multitasking canvas should look.
Managing Sideloaded Apps with the ‘Manage Unknown Apps’ Hub
On the security side, One UI 9 introduces a new ‘Manage unknown apps’ submenu under Settings > Security and privacy > More security settings. This hub automatically lists software installed from non-approved sources—anything outside the Google Play Store or Galaxy Store. Instead of trawling through potentially hundreds of installed apps, users get a curated list of sideloaded apps that may not have passed the same security and privacy checks as store-distributed software. From this screen, it becomes far easier to spot tools you no longer recognize or trust and remove them. Samsung complements this sideloaded apps management approach with improved protections that warn about high-risk apps, can block their installation or execution, and recommend deletion through security policy updates. The result is a clearer distinction between vetted apps and unknown quantities, giving users a straightforward way to audit what’s really running on their phones.
Balancing Usability and Galaxy Phone Security
Taken together, hidden app handles and the Manage unknown apps menu illustrate Samsung’s attempt to balance usability with security in One UI 9. On one side, multitasking becomes less visually noisy, allowing power users to retain full functionality while decluttering their split-screen sessions. On the other, Samsung tightens Galaxy phone security by surfacing sideloaded apps that could otherwise hide in a long app list, while relying on the existing safeguards of the Google Play Store and Galaxy Store. This dual emphasis suggests a design philosophy where control and transparency are key: users choose how their interface looks and feel, while also gaining a clearer view of potential vulnerabilities. If these features make it to the stable release, they will give Galaxy owners finer-grained control over both their on-screen workspace and the software ecosystem they rely on every day.
