Great news for Samsung fans! The One UI 8.5 beta update has officially begun rolling out to devices participating in the beta program. The Galaxy S25 series is the lucky first recipient of this new software, which is built on Android 16. It’s hitting select markets now, bringing with it a handful of tweaks and bug fixes. This isn’t Samsung’s first rodeo with this beta; they released the third One UI 8.5 beta earlier this year. Looking ahead, we expect the upcoming Galaxy S26 series to come with One UI 8.5 right out of the box, with its grand unveiling likely set for February 25 at Samsung’s first Galaxy Unpacked event of the year.

We’re talking about a chunky 1.5GB update here, which also bundles in the February 5, 2026, security patch. It brings a welcome array of bug fixes, including a noticeable fix for the lock screen clock, which was previously prone to shifting downwards.
This newest One UI 8.5 beta from Samsung also tackles common frustrations: it resolves issues with search history in the Phone app, improves Bluetooth headset call switching, and fixes problems when pasting phone numbers into the keypad after tapping a call link. Plus, it smooths out some kinks with the AI Select feature.
In related news, rumors about the Samsung Galaxy S26 Series launch date have already started circulating.
In another discovery, tipster Tarun Vats suggests that the fourth One UI 8.5 beta introduces a handy “Direct Voicemail” feature for the Galaxy S25 lineup. This means you can set your phone to automatically send all incoming calls to voicemail after a specific duration. You’ll also have the option to manually redirect calls straight to voicemail. The best part? All your voicemails will appear directly in the Samsung Phone app, and you can even read a text transcript while the voicemail is being recorded.

It’s widely anticipated that Samsung will officially launch One UI 8.5 alongside the Galaxy S26 series, with the much-awaited Galaxy Unpacked event reportedly scheduled for February 25. This major update is expected to introduce several exciting additions, such as enhanced Pro camera presets, a new Network Battery Saver mode, and improved Priority Notifications. Furthermore, users can look forward to a revamped LockStar module (version 8.5.00.8) which promises hundreds of new unlock animations, offering even greater personalization options.
