Samsung has officially begun rolling out the One UI 9.0 update, based on Android 17, to its 2023 flagship family: the Galaxy S23, Galaxy S23+ and Galaxy S23 Ultra. Distribution started with beta testers in South Korea, and the update is expected to reach a much wider audience in the coming days.

The series' major update tally is complete

The update marks the end of an era for the S23 family. The series launched with Android 13 on board, and Samsung promised these phones a total of four major Android version updates at launch. One UI 9.0 fulfills the fourth and final item of that promise. In other words, the Galaxy S23 series has now received its last major Android upgrade.

While interim releases such as One UI 9.5 could arrive down the line, Samsung has not made any announcement on that front yet. According to available information, the series will not be moving to One UI 10, based on Android 18.

Security support continues until 2028

The end of OS upgrades doesn't mean the devices are done being maintained. Samsung committed to 5 years of security updates for its 2023 flagships. Accordingly, the Galaxy S23 family is expected to keep receiving security patches until early 2028.

S23 users can manually check for the update via the Software Update section in the Settings menu.
