Samsung’s fourth One UI 8.5 beta for the Galaxy S25 series introduces a new Direct Voicemail feature alongside bug fixes and the February 2026 security patch.
Beta Update Details
Firmware ZZAL, weighing 1.48GB, rolls out in South Korea, India, Germany, UK, and US. It fixes lock screen clock shifting, Bluetooth headset call switching, Phone app search history, call link pasting, and AI Select closing issues.
Direct Voicemail Feature
Users can auto-route calls to voicemail after a set time or manually, accessing real-time text transcripts in the Phone app—similar to iOS Live Voicemail, working carrier-independent. Availability beyond Korea is unconfirmed.
Software Rollout Context
One UI 8.5 stable debuts with Galaxy S26 in weeks; betas started December on S25 series, with this fourth build enhancing stability ahead of stable release.
