The Samsung Galaxy S25 series has begun receiving the Android security update for May 2025, marking an early rollout in the US as of May 2. This quick release is a departure from Samsung’s typical schedule, where updates generally start in Korea before expanding to other markets. Traditionally, unlocked devices receive updates first; however, the current rollout prioritizes carrier-locked models in the US, including the Galaxy S25, Galaxy S25+, and Galaxy S25 Ultra.
The firmware version S93xUSQS3AYDF is active for these devices, as confirmed by user reports. While this update is significant in its timing, it is relatively minor in nature, primarily focusing on security enhancements. It does not introduce new features or significant changes to the user experience.
For some context, the Galaxy S25 series originally shipped with Android 15 and One UI 7. This means that unlike many other Samsung devices that may recently have received updates, the Galaxy S25 lineup has not undergone any major version changes in the last month. Although the specifics of the latest security update have not yet been disclosed by Samsung, users can anticipate that it will address a number of security vulnerabilities affecting both Android and One UI 7.
If you own a carrier-locked Galaxy S25 model in the US, be on the lookout for the update if you haven’t accessed it already. Additionally, updates for unlocked models are expected to commence soon, so users should stay attentive to their devices for the arrival of these enhancements.
