Why One UI 9 could be last One UI update for Galaxy S23 series

Key Points:

• Samsung's Galaxy S23 series, including S23, S23+, S23 Ultra, and S23 FE, is expected to receive Android 17 with One UI 9 in the latter half of 2026, marking the final major OS upgrade under Samsung's four-generation update policy.
• After One UI 9, the S23 series will likely not receive any new One UI versions or major feature updates, although security updates will continue for at least one more year.
• The limitation stems from Samsung's handling of mid-cycle updates like One UI 8.5, based on Android 16 QPR2, which introduced significant platform changes making it difficult to backport to older devices; One UI 9.5, expected to be based on Android 17 QPR2, will likely follow the same pattern.
• Samsung's update policy, which now offers seven years of updates for the S24 series and newer, was not applied retroactively to the S23 series, making exceptions for extended support unlikely despite comparisons to Apple's longer update cycles.
• Other 2023 devices under the four-upgrade policy, such as the Galaxy Z Fold 5, Z Flip 5, Galaxy A54, A34, and Tab S9 series, may face similar update limitations, with Android 17 potentially being their final major OS upgrade and One UI 9 the last feature update.
