The Samsung Galaxy S25 series has started receiving the One UI 8.5 beta 5 update. The latest beta software contains several bug fixes and provides stability. This is likely the last beta before a stable release.

Additionally, the February 2026 security patch has been tagged with the latest Beta update. It provides fixes for 25 that come from Google for Android, and 12 are provided by Samsung Mobile for additional protection of the One UI operating system.
The One UI 8.5 Beta 5 software includes an updated Bixby version that improves the usability experience. Moreover, this beta version updated your Samsung apps to the latest available versions.
One UI 8.5 Beta 5 update changelog:
- Version – One UI 8.5, ZZAN

Samsung also revealed that the One UI 8.5 official rollout for the Galaxy S26 series will begin next week. That said, users of these flagships can expect the Stable update next month, and no new Beta will be provided in between.
If you’re already part of the One UI 8.5 beta program, you can get beta 5 on your Galaxy by going to Settings > Software updates > Download and install.
Samsung is working on the One UI 8.5 based on Android 16 QPR2 on the Galaxy S25 series. The One UI 8.5 is Samsung’s latest version of Android customisation for Galaxy smartphones. Now, the reportred tha Samsung may offers more refined UI design for the upcoming One UI 9, which is based on Android 17.
With One UI 8.5, Samsung has replaced the rectangular bottom bar with the rectangular tabs found in One UI 8.
According to @tarunvats33, One UI 9 will further enhance the pill-shaped design across all apps. Therefore, Samsung fans are hoping the company will add frosted glass and smoother animations in the upcoming update.
A tipster shared images of Quick Share from One UI 9.0 on their X handle. As you can see in the images below:
It has a more compact floating pill-shaped bottom bar compared to One UI 8.5, and the tabs also look more rounded.
We expect One UI 9 to officially launch around July 2026, probably alongside the launch of the Galaxy Z Fold 8 and Z Flip 8. On the other hand, Samsung hasn’t yet confirmed when One UI 9 will arrive, so keep an eye on the Samsung Members app for the official roadmap later this spring.
This update will be based on the Android 17 operating system. The foldable devices will be the first to launch with the latest OS pre-installed.
Samsung is gearing up to launch its next flagship S series smartphones, the Galaxy S26, Galaxy S26 Plus, and Galaxy S26 Ultra, and now we have the latest “possible” look via unofficial leaked renders, showing the phones in black from different angles.
Certain tipsters have suggested the design of the new Galaxy S26 series way before its launch. Some said that it could bring a vertical pill shape bump in the base layer, encompassing three rings on the back, just like its predecessor, while others are now hinting at a box-like imaging system.
Amid this confusion, alleged renders of the Samsung Galaxy S26 Plus and Galaxy S26 Ultra are emerging from YTECHB, showing what the devices could actually look like. It may adopt stunning dynamic shades this time: Black, showing the device from all angles.
Looking at the renders in detail, the biggest design change is the rear camera on the Galaxy S26 Ultra. Instead of the old separate rings, it now features a single camera island inspired by the Galaxy Z Fold 7, giving the back a clean, modern look.
With the launch approaching on February 25th, official renders of the Galaxy S26 series have leaked, and we expect more interesting leaks to emerge soon. Samsung has also started taking pre-reservations for it in many countries, including the US and India.
