Samsung has issued software updates for various Galaxy devices. Older models, including the Galaxy S8, S8+, and Note8, received firmware updates intended to improve performance, stability, and reliability, though these did not include new Android versions or recent security patches.

Following the transition to Android 17 (One UI 9), Samsung released a series of stability-focused updates for the Galaxy S25 flagship lineup, including the S25, S25+, S25 Ultra, and S25 Fan Edition. In South Korea, an unusual 698 MB firmware update (build suffix DZJB) was released in lieu of the expected November security patch to address unresolved terminal stabilization issues. This has since expanded into a global rollout aimed at fine-tuning One UI 9.0, addressing minor bugs, and optimizing performance without introducing new functional features. File sizes for these updates vary by model, with the S25 Plus receiving approximately 712 MB and the S25 FE receiving roughly 465 MB.

Additionally, reports indicate Samsung may be reviewing its software support policies for older Galaxy Watch models. While these devices might continue to receive security updates, they may no longer receive new features or operating system upgrades, potentially limiting future support compared to newer series.
