Samsung has begun rolling out the January 2026 security update for the Galaxy S25 series in Canada, continuing its commitment to timely software support for flagship devices. The update arrives shortly after its initial release in select regions and is now expanding to North America.
What’s New in the January Update
This update is focused entirely on security and system stability rather than new features. It includes:
- Fixes for 50+ security vulnerabilities affecting Android and Samsung-specific components
- Improvements to overall system reliability
- Enhanced protection against potential exploits and threats
The Canadian firmware version ends in BYLR and has a download size of approximately 554MB, which is typical for monthly Samsung security patches.
Supported Devices
The update is rolling out to all Galaxy S25 models in Canada, including:
- Galaxy S25
- Galaxy S25+
- Galaxy S25 Ultra
Both carrier-locked and unlocked units are receiving the update in stages, so availability may vary depending on region and carrier.
In addition to the Galaxy S25 series, Samsung is expected to roll out the January 2026 security update to other eligible Galaxy devices in the coming weeks. This typically includes earlier flagships like the S23 families, select models from the Galaxy Z foldable lineup, and newer mid-range phones that are still within Samsung’s update support window. Samsung’s continued monthly patch schedule helps ensure that a wide range of Galaxy devices remain protected against the latest vulnerabilities.
How to Install
Users can manually check for the update by navigating to:
Settings → Software update → Download and install
As with all OTA updates, a stable Wi-Fi connection and sufficient battery charge are recommended before installation.
Why This Update Matters
Monthly security updates play a crucial role in keeping devices protected against newly discovered vulnerabilities. Even without visible changes, these patches ensure that Galaxy S25 users continue to benefit from strong security, performance stability, and long-term software support.
