TL;DR
- Samsung has released the fourth One UI 8.5 beta (firmware ZZAL) for the Galaxy S25 series, including the February 5, 2026, security patch.
- The 1.48GB update resolves issues with the lock screen clock, Bluetooth headset call switching, and AI Select closing behavior.
- A new Direct Voicemail feature allows users to send calls to voicemail automatically or manually, with real-time text transcripts available in the Phone app.
One UI 8.5 is Samsung’s next big software release, but it will only launch in its stable avatar with the Galaxy S26 series in the coming weeks. In the run-up, the company has been testing One UI 8.5 beta releases on the Galaxy S25 series. The first two One UI 8.5 betas were released in December, while the third was released in January. A month later, we now have the fourth One UI 8.5 beta release for the Galaxy S25 series.
