Samsung Update Rollout

Samsung began rolling out the One UI 8.5 update (version S938USQU9CZDP, 4.4 GB) to the S25 series in United States, covering the Z Fold/Flip 7-6 and Tab S11/S10 series.
The Android 16 update adds the April 2026 security patch, call screening, Bixby, Quick Share to Apple devices, and a Liquid Glass interface.
Samsung said the rollout will expand to the S23 series and A-series phones soon, with carrier-locked devices receiving it later.

Summary

Samsung AirDrop Issues

Users report AirDrop failures that require reboot and occasional animation lag on the Galaxy S25 after One UI 8.5 installation.
The stable rollout began in South Korea, where beta participants received One UI 8.5 a week before the United States.
Samsung will announce One UI 9 with the Galaxy Z Fold 8 and Z Flip 8 later this summer.
Leakers say the Galaxy S26 will be the first test device, with internal builds already downloadable in Korea.

Summary

Samsung Extends Beta

Samsung launched the One UI 8.5 beta on 8 December 2025, starting a five-month testing period.
The beta reached the Galaxy Z Fold 7 in mid-March 2026, extending the program beyond the S-series before the stable release.
Analysts note that the update, a skin refresh on Android 16 that does not change the underlying Android version, has a five-month beta that is unusually long, similar to the One UI 7 rollout in 2025.
