Samsung Galaxy S23 series phone users are sure of a new update every month. It’s always predictable when the rollout will start, but difficult to say which region will get it first. The update is rolling out in South Korea, and some units in the US can upgrade.

The new Galaxy S23 update is the March 2025 security patch. It started rolling out last week with the Galaxy Z Fold 6 and Galaxy Z Flip 6 among the few phones to receive the upgrade. Samsung has extended the release to the Galaxy S23 series but limits it to carrier-unlocked variants in the US and those in Korea.
