Samsung’s Galaxy A34 5G is getting stable One UI 9, based on Android 17, in Europe and other international markets. Firmware tracker Tarun Vats (@tarunvats33) spotted the rollout, as reported by GSMArena. Based on Samsung’s own support promise, this should be the 2023 phone’s last major Android upgrade.

Why One UI 9 is the Galaxy A34’s final major upgrade
The Galaxy A34 5G launched in 2023 running Android 13 with One UI 5.1. Since then it has moved to Android 14, 15 and 16. Android 17 makes four OS upgrades in total.
That count matches what Samsung promised when it announced the phone alongside the Galaxy A54:
“Galaxy A54 5G and Galaxy A34 5G also guarantee up to four generations of OS upgrades and five years of security updates.”
With four upgrades delivered, Samsung has met that commitment. The A34 now follows its sibling, the Galaxy A54, which got One UI 9 in Europe earlier this month as its last major update. The A34 is also on our list of Samsung devices getting One UI 9 as their final upgrade.
Galaxy A34 One UI 9 build numbers and download size
The update arrives over the air as a 2.8GB download. The build number depends on your region:
- Europe (SM-A346B): A346BXXUHGZJ8
- Global (SM-A346E): A346EXXUGGZJ9 / A346EOJMGGZJ9
The update carries the October 5, 2026 security patch rather than November’s. That puts the A34 a month behind on security fixes as it moves to One UI 9.
The rollout appears to be going out in waves, so it may take days or weeks to reach every phone. As of November 10, no Samsung statement on the A34 rollout has surfaced. The reports so far cover the international models listed above.
How to check for the update
- Open Settings.
- Tap Software update.
- Tap Download and install.
At 2.8GB, this is a large download, so connect to Wi-Fi first. If nothing shows up yet, check again in a few days.
What support is left after One UI 9
Major Android upgrades end here, but security updates do not. Samsung promised up to five years of security updates from the A34’s 2023 launch. By our count, that support should run into 2028. That is our estimate from the launch date, not an end date Samsung has given.
