When will it end? Galaxy S25 series gets tenth One UI 8.5 beta

If you were hoping to taste Android 16 on your Galaxy S25 series flagship, you’ll still have to wait a bit more. Samsung is back with yet another One UI 8.5 beta, now at Beta 10. Tarun Vats reports on X that One UI 8.5 beta 10, with firmware version ending in ZZDD, is rolling out to Galaxy S25 series owners in South Korea, India, Germany, and the UK.

Given Samsung’s previous plans, this update should also roll out to the Galaxy S25 series in the US very soon, and comments on the post indicate it’s already happening.

This ZZDD build is approximately 915 MB and includes the April 5, 2026 security patch level. Big highlights from the changelog are “new AI features” and a ton of bug fixes:

• Added new AI features.
• Fixed an issue where the incoming call screen appears late or shows a black screen when receiving a call.
• Fixed a proximity sensor error during calls.
• Fixed an issue where green lines appear when recording videos in 4K HDR with the camera in certain 3rd party apps.
• Improved Bluetooth crash issues.
• Improved multi-touch malfunction after using accessibility magnification.

While we appreciate that Samsung is doing its best to fix bugs, it’s still a little disappointing to see the company’s ex-flagship still running an outdated Android version, even though Android 16 has been out for months. We hope Samsung allocates more resources, fixes bugs, and rolls out a stable One UI 8.5 update for the Galaxy S25 series soon.
