What you need to know
- Samsung is expanding the stable One UI 9 (Android 17) update to the Galaxy A36 globally, landing in Europe after its initial South Korea launch.
- The over-the-air update (version A366BXXUCDZIF) weighs in at over 2.3GB and bundles the September 2026 security patch.
- The Galaxy A36 release is rolling out alongside updates for other A-series models, including the Galaxy A56, A37, and A27.
Samsung is rolling out its stable One UI 9 update to the Galaxy A36 in global markets, with Europe among the first regions outside South Korea to get the software. The rollout started on October 19, so owners of midrange phones can now enjoy Android 17 and Samsung’s latest interface improvements without having to buy a newer Galaxy device.
The update carries firmware version A366BXXUCDZIF and includes the September 2026 security patch, as spotted by X user @Kailash0729 (via SammyGuru). The download is over 2.3GB, so make sure you have a good Wi-Fi connection and enough free storage before you begin installing. Just don’t expect Samsung to port every flagship feature to its more affordable hardware.
One UI 9 brings interface tweaks, more customization features, and security improvements. The update also is based on Android 17, while Samsung continues to customize some features for individual devices. The more advanced Galaxy AI features are still largely limited to compatible higher-end phones, so the A36 misses out on some of the more fancy additions.

It starts with a first stable release in South Korea on October 15, where the Galaxy A36 was shipped with the firmware version A366NKSU9DZIF. Samsung has since started to roll out availability outside of its home market, as well as updates for other Galaxy devices, including the Galaxy A56, A37, and A27.
But a global rollout doesn’t mean every country gets the update at once. Samsung typically releases major software updates in phases, so some owners may have to wait days or longer for the download to appear.
