Samsung has started rolling out the official and stable One UI 7.0 update (based on Android 15) for the Galaxy S23 series in the South Korean market. This is the next update after the company re-deployed One UI 7 to the Galaxy S24, Z Flip 6, and Z Fold 6 last week.

According to @tarunvats33, Galaxy S23, S23+, and S23 Ultra users in South Korea can now download the One UI 7.0 update with firmware code S91xNKSU6DYD9. For devices that have participated in the beta testing program, the update size is only about 1GB, while devices that have never signed up for the beta will receive a larger update of about 5GB. In addition to performance and feature improvements, this update also comes with the April 2025 security patch.

Samsung has also officially ended the One UI 7 Beta program for the Galaxy S23, which means that all users of this model in Korea will soon receive a stable update in the next few days. It is likely that other international markets will also receive this update within the week.

Users can check for updates by going to Settings > Software update > Download and install. This is a major update, so make sure you have enough battery capacity and use a Wi-Fi connection before updating.
