Samsung India’s One UI 9 page lists the Galaxy S24 and S25 families among models whose Android 17 upgrade is completed in October 2026. The page, last updated October 13 and checked on October 19, does not list the Galaxy S23. That leaves the S23’s Indian release date unconfirmed by this source; the October 14 S23 release record available from Samsung applies to the Korean SM-S911N model.
The distinction matters as One UI 9 reaches older Galaxy phones. Owners deciding whether to download the update need a record for their model and market, alongside the update actually offered on the device. Samsung’s own update history warns that content can differ by model, country and carrier. A release for one variant therefore cannot establish when every other variant receives it.
Samsung India’s completed-upgrade list

| S23 | Not listed in this October 13 record |
Official page last updated October 13; read October 19. This is a completion list, not a forward rollout calendar or proof of every handset’s current OTA status.
What the India completion list actually records
The India page records September completion for the S26, S26+ and S26 Ultra. Its October entries include S25, S25+, S25 Ultra and S25 FE; S24, S24+, S24 Ultra and S24 FE; Z Fold7, Z Flip7, Z Fold6 and Z Flip6; and A57. These are the models displayed in the completed-upgrade section, not a new schedule promising a future date for every supported phone.
The age and purpose of that list limit what can be concluded about an absent model. The S23 is not shown in the October 13 record, but the page also says more models will be added as rollout continues. Its absence does not prove that the S23 is ineligible or that no Indian handset has received an update since then. The list alone cannot supply a firm day for an Indian S23 download.
What the Korean S23 update does establish
Samsung’s Korean Galaxy S23 history is more specific about its own variant: SM-S911N received build S911NKSU8GZIF on October 14, with Android 17, One UI 9 and the October 5 security patch level. The release notes describe changes including a more adjustable Quick Panel and a Warranty and Care menu. Those details verify a real release for that Korean model, with the stated date and build.
For an Indian buyer or owner, that record confirms progress in the wider rollout without becoming an Indian firmware announcement. It also separates three dates that serve different purposes: publication of the India list, release of the Korean software and the security patch level. None should be substituted for the date on which an Indian phone is offered the upgrade.
Check the version offered to your own phone
Samsung India’s installation guide gives Settings → Software update → Download and install as one update path; some models use Check for updates, or place Software update under About device. Open that menu, read the available update and follow the on-screen instructions if it is offered. Samsung says the phone restarts during installation. Its guide also distinguishes operating-system upgrades from security updates, so a new security-patch month alone does not establish that Android 17 and One UI 9 have been installed.
The evidence currently supports a completed-upgrade list for several Indian Galaxy families and a dated One UI 9 release for the Korean S23. It does not support one shared S23 release day across both markets. Matching the phone’s model and offered software version to the local record gives owners a concrete basis for deciding what is available, while preserving the distinction between the OS upgrade and a routine security patch.
Based on Samsung India’s completion list and installation guide, and Samsung’s Korean SM-S911N release history. The India list was last updated October 13; absence from it is not proof of device ineligibility.
