May 4 update. This post, first published on May 2, has been updated with further details of when the long-awaited update may finally land.

Samsung’s latest software, One UI 8.5, was expected to launch for millions of Galaxy phones from April 30. But nothing’s happened yet. Here’s what’s going on, and details of exactly when users can expect to see the release.

One UI 8.5 is already on the latest S26 series of phones. But its expected release for the S25 series hasn’t happened yet. When it eventually arrives, it will add new features and visual upgrades without the need to splash out on the latest model.

Samsung has said that April 30 was never the official date for the rollout to start. Since May 1 is Labor Day in Korea, a rollout beginning hours before a public holiday could have proven tricky for support teams.

“Please note that Beta schedules are not finalized until officially confirmed by Samsung, and timelines may change depending on testing results or regional considerations,” the company said in a One UK Beta Team community site.

New Likely Release Window

Which means that Monday, May 4 is the date that seems most likely. This could be for Korean users only, at first, with international rollout beginning after that.

“Samsung plans to release the stable version of One UI 8.5 for most eligible Galaxy smartphones and tablets between May 4, 2026, and May 30, 2026. This means the stable build of the new software for your device could be less than a month away,” SamMobile claimed.

That date has arrived with no sign of the release. However, a new report from Sammy Fans suggests there may not be long to wait. The site claimed that May 4 was being “avoided due to regional considerations, “ and quoted an online chat with a Samsung representative. This didn’t give a new date but said that “we will post an update notice in the announcements section of the Samsung Members app at the time of the product update.”

Sammy Fans went on to give a date prediction. “Our assumptions point to May 6 for South Korea, followed by Global markets within a week. A Canadian moderator ruled out the possibility of a simultaneous rollout for a wide range of models, so an undefined delay is likely.”

There are many updates in One UI 8.5, including support for Quick Share’s latest feature , compatibility with Apple iPhone to make wireless transfer between Android and Apple devices as smooth and seamless as it is with AirDrop.

Other major additions include Perplexity-powered Bixby, AI-driven Photo Assist, and real-time Audio Eraser to filter background noise from media.

“Beta testers also praise the software’s fluidity and stability, as compared to the One UI 8.0 software,” Sammyfans has said.
