When will Android 15-based One UI 7 be available on your Samsung Galaxy device?

The big One UI 7 upgrade, which is based on Android 15, is keenly anticipated by Samsung Galaxy customers. Samsung, one of the largest companies in the Android ecosystem, is lagging behind as Google and other manufacturers have already released the most recent OS.

This year, Samsung’s upgrade procedure has not gone smoothly. In late 2024, the business first launched a One UI 7 beta program. Samsung now plans to release a stable upgrade beginning in April 2025 after experiencing setbacks. Here is what we currently know about the schedule and what to anticipate.

One UI 7 Beta Rollout Timeline:

Beta Launch: Starting with the Galaxy S24 series (S24, S24+, and S24 Ultra) in a few countries, including the US, UK, Germany, South Korea, Poland, and India, the One UI 7 beta program got underway on December 5, 2024. This was the initial wave, which qualified users may access through the Samsung Members app.

Beta Expansion: (March 2025): On March 5, 2025, Samsung officially expanded the beta program to additional devices. The Galaxy Z Fold6 and Z Flip6 joined the beta in countries like India, Korea, the UK, and the US starting that week. Later in March 2025, the beta will be extended to the Galaxy S23 series (S23, S23+, S23 Ultra), Galaxy Tab S10 series, and Galaxy A55.

There are several beta builds available for the Galaxy S24 series: The company published other betas following the initial one on December 5th; see below for details.

• Beta 2: December 16, 2024
• Beta 3: January 6, 2025
• Beta 4: February 19, 2025 (followed by a hotfix on February 21, 2025)

The beta period, which will last from December 2024 to at least March 2025, has been noticeably extended as Samsung fixes faults and refines the update, which includes major UI improvements.

One UI 7 Stable Rollout Timeline:

• Initial Stable Release: The stable version of One UI 7 debuted with the Galaxy S25 series (S25, S25+, S25 Ultra) on January 22, 2025, unveiled at the Galaxy Unpacked event. These devices shipped with One UI 7 pre-installed, marking the official launch.
• Stable Rollout Start: Samsung confirmed on March 5, 2025, that the stable One UI 7 rollout for existing devices will begin in April 2025. No exact date was specified, but April is the official starting point.
• First Wave (April 2025): The Galaxy S24 series is expected to be the first to receive a stable update in April 2025, given its extensive beta testing (four builds by February 2025). The Galaxy Z Fold6 and Z Flip6 are also likely candidates for early April, following their beta inclusion.
• Second Wave (May 2025): The Galaxy S23 series, Galaxy Tab S10 series, and Galaxy A55, which joined the beta in March, are slated for a stable update shortly after the S24 series, likely in early May 2025.
• Broader Rollout: Older flagships (e.g., Galaxy S22, S21 series, Z Fold5, Z Flip5, and eligible foldable) and additional mid-range devices (e.g., Galaxy A54, A34) are anticipated to receive the stable update gradually through Q2 2025 (May–June), though exact dates remain unconfirmed. Budget models may extend into Q3 2025.

A leaked timeline from a Samsung Romania workshop added to the above schedule by speculating on specific dates such as April 18 for the S24 series and May 23 for the S21 series. It is speculative, though, as Samsung has not formally verified (refuted by the official moderator).

The end is finally in sight for Samsung Galaxy users who have been patient—or not so patient—waiting for One UI 7. Samsung’s major Android 15 update is expected to give millions of devices a smooth, updated experience as beta testing comes to an end and the stable distribution begins in April 2025. Although the delays have caused Samsung to lag behind rivals such as Google, the additional time may result in a One UI 7 that is more feature-rich and seamless.
