Samsung has started testing Android 16-based One UI 8 on the Galaxy Z Fold 5. This big result shows that the Korean tech giant is considering the 2023 foldable, which could also be included in the Open Beta program this year.

After Galaxy S and A series devices, Samsung’s Android 16 optimization for Galaxy devices is in full swing, with foldable models not being added to the testing zone.

A reliable tipster, @Tarunvats has spotted a new One UI 8 build for the Galaxy Z Fold 5 on the testing platform. The testing build, F946BXXU5FYG2, hints that Samsung is actively working on One UI 8 for the Galaxy Z Fold 5.

Notably, last month, a carrier-locked variant (SM-F946U) of the Galaxy Z Fold 5 for the US was spotted on Geekbench running Samsung’s Android 16-based One UI 8.0.

The One UI 8 update will bring meaningful changes to the UI. The company is also working on redesigning apps and core functionality to further improve the appearance and foundation laid by the Android 15-based One UI 7 update.

Samsung has started expanding One UI 8 Beta to Galaxy S25 devices, allowing users to enjoy new features and enhancements ahead of an official release. Meanwhile, the company is also rolling out the June 2025 security update for the Samsung Galaxy Z Flip 5 and Galaxy Z Fold 5 smartphones.

Samsung’s June 2025 security update for Samsung Galaxy Z Flip 5 and Galaxy Z Fold 5 is currently available in Europe, and the company will expand it soon to more countries. The fresh update installs the latest Android security patch released in June 2025 to improve system security.

June 2025 security update for Samsung Galaxy Z Flip 5 and Galaxy Z Fold 5 can be identified via One UI build version F731BXXS5EYF1 and F946BXXS5EYF1, respectively. It is an initial rollout, so it may take some hours or days to reach all models.

It is worth noting that this update is based on Android 15 and One UI 7. Users of these devices will get the One UI 8 update in the coming months. Samsung has not confirmed these smartphones for beta, so it is possible that users may get the stable update directly.
