Verizon has released the October 2026 security update for the Samsung Galaxy S25, Galaxy S25+, and Galaxy S25 Ultra in the US. The carrier’s release pages for the Galaxy S25, S25+, and S25 Ultra date all three updates October 22, 2026, and list security patches as the change.
If you’re checking your phone today, I’ve put the confirmed firmware versions below. Each model has its own build, so compare yours with the matching row.
Which Galaxy S25 builds are available on Verizon?
Verizon lists October 2026 security updates for all three Galaxy S25 models below, released October 22. Their firmware identifiers end in DZJ1. These are the carrier’s US releases, so the table should be used to check a Verizon handset rather than establish availability for other carriers or countries.
| Device | Firmware identifier | Official release notes |
|---|---|---|
| Samsung Galaxy S25 | S931USQSDDZJ1 | Verizon Galaxy S25 |
| Samsung Galaxy S25+ | S936USQSDDZJ1 | Verizon Galaxy S25+ |
| Samsung Galaxy S25 Ultra | S938USQSDDZJ1 | Verizon Galaxy S25 Ultra |
Verizon puts CP2A.260605.016. before each firmware identifier in its full software version. All three pages list October 2026 as the Android security patch level.
What does the October update change?
The new release notes list Android security patches. They don’t announce a new One UI version or describe camera, battery, or performance fixes. I’d treat this as a maintenance update and avoid expecting a particular problem to disappear unless Samsung or Verizon documents the fix.
There’s a useful distinction in Verizon’s Galaxy S25+ history: the previous release, dated October 5, 2026, brought Android 17 and One UI 9 with the September security patch. The October 22 release moves the security patch level forward.
