After rolling out the March 2026 security patch to the Galaxy S25, Galaxy S25+, and the Galaxy S25 Ultra in Europe and South Korea, Samsung is now offering it in the US.
At the moment, the brand seems to have released the latest security update to the carrier-locked variants of the three phones. The update is 570.65MB in size and carries version S93xUSQS8BZBB (via @FlamezzHitz and @tarunvats33). Factory-unlocked versions of the three devices should also get the update soon.
The March 2026 security patch fixes 65 security issues, making these devices more secure. To get it, go to Settings > Software update > Download and install. You can also download the new firmware from our database and install it using Odin.
