Samsung has been beta testing Android 16-based One UI 8 for the Galaxy S25 lineup for a while now. So far, it has seeded seven beta builds. With the public release scheduled for September, you’d expect the company to start pushing the stable build to S25 owners. Instead, Samsung has just released an eighth beta update for the phones.
The 600MB+ ZYI3 firmware primarily fixes all the reported bugs, including one for the clock stuttering on the lock screen while locking or unlocking the device. The update is already live in India, South Korea, Germany, and the UK (via @tarunvats33).
If your S25 is already running the previous One UI 8 beta, grab the new build from Settings > Software update > Download and install. The full release notes of the ZYI3 firmware are as follows:
Bugs that have been fixed:
– Fixed the issue that Lock screen clock position continues to move down
– Fixed breaking Bluetooth sound
– Fixed the issue that Stretch Font not applied
– Fixed the issue that after the update, the input letters of Nowbar, Status Bar, and Lock Screen PIN are displayed thinly
– Fixed disappearing lock screen quick run icon while using
– Fixed clock stutters when unlocking or locking lock screen
Samsung typically releases five or six beta firmware for its devices before pushing the stable build to the public. For the S25 lineup, One UI 8 appears to need more fine-tuning, pushing the beta count to eight.
Galaxy S25’s One UI 8 beta 7 dropped in late August, while Samsung has pushed the eighth beta just ten days later.
One UI 8 should go public soon
Based on an allegedly leaked public release timeline from Samsung, the stable One UI 8 firmware for the Galaxy S25 lineup should release on September 18. The S24 family will then get the update a week later, on September 25.
These are obviously tentative dates, and Samsung could push the update to the public a day or two earlier. Or it can delay the release if it runs into some last-minute issues, like it did with One UI 7’s public build earlier this year.
