Samsung continues testing One UI 8.5 beta for its flagship Galaxy phones. Besides rolling out the eighth beta build for the Galaxy S25 series and the second beta for the Galaxy Z Fold 7, it has also expanded the program to include its 2024 flagship: the Galaxy S24.

The One UI 8.5 public beta program initially opened in the second week of December 2025 for the Galaxy S25 family. Following its public release on the S26 series in early March, Samsung opened the program to include the Galaxy Z Fold 7 and Flip 7. Now, it’s extending the beta to more devices, bringing the Galaxy S24 lineup into the fold.

The ZZCD One UI 8.5 beta for the S24 Ultra, S24+, S24, and even the S24 FE is currently live in South Korea, India, and the UK. You can grab it after enrolling in the One UI beta program through the Samsung Members app. Tap the banner, accept the terms and conditions, and wait for a few minutes for the OTA to appear on your phone.

The 4.4GB firmware contains the March 2026 security patch along with a bunch of changes, such as a smarter Bixby experience, Storage share, enhanced Weather widget, and more.
