Samsung has confirmed the rollout schedule for its upcoming One UI 9.0 beta program, with the first phase for the Galaxy S26 series set to begin on May 26.
The update marks the next stage in Samsung’s Android-based software development cycle, focusing on testing new features and system stability before a global stable release.
The company initially announced the beta program on May 12, confirming availability in select regions including the United States, United Kingdom, Germany, South Korea, India, and Poland. However, the rollout will not begin simultaneously across all markets.
Early access limited to four countries
In the first phase, only users in the United States, United Kingdom, Germany, and South Korea will receive access to the One UI 9 beta. These regions are part of Samsung’s traditional early testing group, where software is evaluated under high-usage conditions before wider expansion.
Users in India and Poland will have to wait until the end of May before they can join the beta program. Samsung stated that the phased rollout is designed to ensure system stability and gather early feedback from controlled markets before expanding availability.
Devices included in the beta program
The initial One UI 9 beta is expected to support the full Galaxy S26 lineup, including
- Galaxy S26
- Galaxy S26 Plus
- Galaxy S26 Ultra
Samsung typically limits early beta access to its latest flagship devices to ensure performance consistency and to test software optimization on high-end hardware first.
Why Samsung uses phased beta rollouts
Samsung follows a gradual release strategy for its software testing programs, a method it has used since its early beta initiatives in 2018. Unlike companies such as Apple and Google, which often release beta versions across multiple regions at the same time, Samsung prefers a controlled rollout model.
This approach allows the company to
- Identify bugs early in limited environments
- Collect region-specific user feedback
- Improve system stability before global release
Industry observers say this method reduces the risk of widespread software issues during early testing stages.
Comparison with previous One UI beta cycles
Samsung’s staged rollout pattern has been consistent across recent generations. For example, earlier beta programs were introduced in a limited number of countries before expanding globally over several weeks.
Past releases such as the Galaxy S24 and S25 series updates followed similar patterns, where early adopters received access first, while broader availability took place after initial refinements.
What users can expect next
The One UI 9 beta is expected to evolve through multiple update phases based on user feedback. Early builds typically focus on performance stability, battery optimization, and interface improvements before introducing additional features in later versions.
A wider rollout to more countries and devices is likely to follow in the coming months, depending on testing results and system performance.
For now, Samsung users in supported regions will be among the first to experience the next generation of the company’s Android interface ahead of its official global release.
