The Galaxy S25 Canada update missed its expected November 10 rollout window, leaving Canadian owners on the September 2026 security patch. On November 11, 2026, tipster Tarun Vats spotted a new One UI 9 build (S936WVLUDDZJB) for the Canadian Galaxy S25+ on the XAC channel right after leaker CID called out Samsung Canada for still not shipping the October patch.
If you use a Canadian Galaxy S25, S25+, S25 Edge or S25 Ultra, you can check Settings > Software update > Download and install, though Samsung’s public update server in Canada had not pushed the new build over the air at the time of writing.
Where the Galaxy S25 Canada update stands today
According to Samsung Canada’s official Galaxy S25+ release notes and update server data for the multi-carrier XAC code, all four Canadian models are still running the One UI 9 builds that rolled out on October 6, 2026 with the September 5, 2026 Android security patch.
| Device | Canadian model | Live XAC build (Oct 6) | Spotted test build (Nov 11) | Live patch level |
|---|---|---|---|---|
| Galaxy S25 | SM-S931W | S931WVLUCDZIF | Not listed in post | September 5, 2026 |
| Galaxy S25+ | SM-S936W | S936WVLUCDZIF | S936WVLUDDZJB | September 5, 2026 |
| Galaxy S25 Edge | SM-S937W | S937WVLU9DZIF | Not listed in post | September 5, 2026 |
| Galaxy S25 Ultra | SM-S938W | S938WVLUCDZIF | Not listed in post | September 5, 2026 |
Why did Canadian owners expect the patch yesterday? Samsung Canada did push a Tuesday firmware batch on November 10, 2026, but the S25 lineup wasn’t in it.
Our firmware feed recorded Canadian Galaxy Z Flip 7 units (SM-F766W, XAC) receiving build F766WVLUDCZJB on November 10 with the October 5, 2026 security patch and a stability and reliability changelog. On that same day, the Galaxy S25 series in Taiwan (BRI) and Hong Kong (TGY) picked up its own DZJB update across SM-S9310, SM-S9360, SM-S9370 and SM-S9380, yet Canadian S25 phones were left waiting.
What build S936WVLUDDZJB changes on Canadian models
The full string Tarun Vats shared for the Canadian Galaxy S25+ is S936WVLUDDZJB/S936WOYVDDZJB/S936WVLUDDZJB, replacing the current S936WVLUCDZIF release.
Look at the fourth character from the end: S936WVLUDDZJB uses U in VLUD rather than an S security-only tag. That matches the DZJB builds that landed in Taiwan and Hong Kong yesterday, as well as the ZJB foldable rollout we covered in our Galaxy Z Fold 7 and Flip 7 stability update report, where Samsung focused on One UI 9 stability alongside the October 5, 2026 security patch.
The fifth character from the end also steps up from C (bootloader binary 12) to D (binary 13). As we explain in our Samsung firmware version guide, that character tracks the anti-rollback fuse on your phone. Once your Galaxy S25+ installs a binary D update, Odin will reject any attempt to flash back to the older C-binary DZIF build with SW REV CHECK FAIL.
If the Canadian DZJB package mirrors the SM-S9360 build from November 10, it will bring the SMR-OCT-2026 security patch detailed in our October 2026 security bulletin breakdown rather than jumping straight to the November patch. Samsung has not published an official Canadian release date for S936WVLUDDZJB yet, so treat it as an upcoming test build until the XAC server flips it live.
How to check your Canadian Galaxy S25 firmware
Once Samsung Canada and carriers like Rogers, Bell and Telus clear the DZJB build for release, your phone will pull it over the air. Follow these steps to check your current build number and poll for the Galaxy S25 Canada update manually:
- Open Settings > About phone > Software information and look under Build number and Android security patch level to see if your phone is still on DZIF and the September 5, 2026 patch.
- Go back to the main Settings screen and tap Software update > Download and install.
- Connect to Wi-Fi and keep your battery above 50 percent before tapping Download if the new DZJB update appears.
You can also enter SM-S931W, SM-S936W, SM-S937W or SM-S938W with CSC XAC in our Samsung firmware checker to see the moment Samsung’s server switches from DZIF to DZJB. Are you still waiting on the September patch on your Canadian Galaxy S25, or has your carrier posted a new schedule date? Drop your model number and carrier in the comments.
