Samsung has been testing its Android 16-based One UI 8 beta across multiple Galaxy devices, but the stable release is still pending. While smartphones and tablets that launched with Android 15 or earlier are waiting for the update, the Galaxy S25 lineup, introduced earlier this year, is expected to lead the rollout.
According to a new leak, the stable One UI 8 update will begin reaching users on September 18, starting with the Galaxy S25, Galaxy S25+, and Galaxy S25 Ultra. A week later, Samsung plans to extend the rollout to the Galaxy S25 Edge, the entire Galaxy S24 series, and mid-range models like the Galaxy A56 5G and Galaxy A36 5G.
The leaked schedule also outlines updates for tablets and wearables through October and November, though availability will vary by region. Samsung has not officially confirmed the timeline, but the leak suggests Asia will be among the first to receive it.
