When will Galaxy S25 get One UI 8.5? Tipster calls a new date after Samsung missed the last one

Source: Android Authority

TL;DR

• Samsung is now rumored to release a stable version of One UI 8.5 for the Galaxy S25 later this week.
• The update was originally expected at the end of April, but that deadline was missed.
• The new rumor is based on a rollout timeline reportedly shared by a carrier.

Samsung’s One UI 8.5 has been officially available for over two months, but only on new devices. Owners of older models are still waiting for a stable update, even after almost a dozen beta versions (see beta list). The stable rollout was previously expected (earlier leak) at the end of April, a deadline Samsung missed.

New Rumor from a Tipster

Tipster @theonecid posted on X about the One UI 8.5 rollout schedule. According to the post, the rollout for the Galaxy S25 series, as well as the Galaxy Z Fold 7 and Z Flip 7, could begin around May 8. The dates are reportedly pulled from a carrier’s rollout schedule (source).

The tipster notes that these dates refer to Canada, suggesting a broader global rollout could occur on or around the same date.

Expected Timeline for Older Devices

In addition to the Galaxy S25, the update for older phones—including the Galaxy S24 series—is expected to follow “shortly after.” This assumption is based on a comment from a Samsung Community moderator, shared by user @galaxyupdatesx on X (tweet link).

A “Beta Moderator” in the Samsung Community (via SammyFans) clarified that beta schedules remain flexible until Samsung finalizes them, and “timelines may change based on testing.” This flexibility likely contributed to the missed April 30 launch timeline hinted at by another support staff member earlier.

Additional Speculation

SammyFans also speculates that May 4 could be the day Samsung initiates the One UI 8.5 release in its home market, South Korea, before a wider global rollout. Whether this turns out to be accurate remains to be seen.
