The Samsung Galaxy S23 series is nearing the end of its major Android OS upgrade cycle. The upcoming One UI 9 update, based on Android 17, will be the final feature upgrade for these devices.

• The stable One UI 9 update is anticipated between mid-late October and early November 2026.
• Samsung is expected to follow a rollout pattern similar to the Galaxy S22's One UI 8 release.
• Unlike newer flagships, the Galaxy S23 lineup is covered under the previous four-OS-update policy, meaning One UI 9 is its last.
