Samsung’s beta testing of One UI 8 for the Galaxy S25 series has been going longer than anticipated. Despite the program starting in late May, the company has yet to push the stable version to its 2025 flagship. Even the pace of new beta build rollouts has been slow, with the fourth test firmware arriving in late July, a month after the last one. Now, three weeks later, Samsung has seeded One UI 8 beta 5 for Galaxy S25 users enrolled in the program.

The ZYH6 firmware primarily focuses on squashing all the reported issues, including those with the Quick Settings panel and mobile data hotspot. The 1.7GB update also contains the August 2025 security patch. For S25 owners who are not a part of the beta program, a One UI 7 update with the August security patch is already live.

If you are part of the Galaxy S25 Android 16 public beta, you can grab the new build from Settings > Software Update > Download and Install.

The full release notes of the update are as follows:

  • Fixed hotspot connection error
  • Fixed the issue of the size of the clock on the lock screen getting smaller
  • Fixed S Pen Air command exception
  • Fixed issue of Quick Settings window not appearing
  • Fixed the issue that overlap the Quick Settings and Notification Windows
  • Fixed the exception when capturing screen in the app in the secure folder
  • Fixed the issue of moon appearing purple when taking a picture with 100X Zoom
  • Fixed an issue of Do Not Disturb Mode’s settings resetting
  • Fixed the issue of Now Brief briefing content disappearing
  • Stabilizes SW with multiple App Update
  • Applied August security patch

The ZYH6 firmware is already live in the UK, India, and Germany.

Stable One UI 8 for the Galaxy S25 lands in September

This could be the last or penultimate One UI 8 beta firmware for the Galaxy S25 ahead of the public release next month. Samsung has already confirmed it will push out the stable Android 16 build to its 2025 flagship phone in September.

While the Galaxy Z Fold 7 and Flip 7 also run on One UI 8 out of the box, the S25 should run a newer build with possibly more features and changes. Here’s hoping it brings the artistic watermark available on the Chinese firmware.
