The Galaxy A34 5G moves from One UI 8.5 to One UI 9 and Android 17 in Europe, the Middle East, Africa and Asia-Pacific. It's the phone's fourth major Android upgrade, and it keeps the October 2026 security patch.
Samsung has started rolling out One UI 9, based on Android 17, to the Galaxy A34 5G outside South Korea. Samfrew's catalogue picked up the new firmware early on November 9, 2026:
- Galaxy A34 5G (SM-A346B), Europe: A346BXXUHGZJ8 in 20 CSCs, from 03:17 UTC
- Galaxy A34 5G (SM-A346E): A346EXXUGGZJ9 in 41 CSCs, mostly in the Middle East, Africa and Asia-Pacific, from 06:59 UTC
Korea got there first: the Korean model (SM-A346N) has had One UI 9 since November 4.
Inside the firmware
Samfrew reads these details straight from the firmware files:
- Software: One UI 9.0 on Android 17 (API level 37), up from One UI 8.5 on Android 16
- Security patch: October 5, 2026. That's the same level as October's update, so this release brings new software, not newer security fixes.
- Build number: CP2A.260605.016.A346BXXUHGZJ8 (Europe)
- Bootloader revision: H on the SM-A346B and G on the SM-A346E, both unchanged from October's update
- Linux kernel: 6.6.127, up from 6.6.92
- CSC: A346BOXMHGZJ8 in every European CSC. On the SM-A346E it depends on the market: A346EOJMGGZJ9 in the Middle East and Africa, A346EOLMGGZJA in Asia-Pacific, A346EOLEGGZJA in Indonesia and A346EOXEGGZJA in Ukraine, Georgia and Kazakhstan.
- Download size: 10.2 GB for the European firmware
Its fourth major Android upgrade
The Galaxy A34 5G launched in March 2023 with Android 13. Samfrew's catalogue first saw Android 14 for it in November 2023, Android 15 in June 2025 and Android 16 in October 2025, which makes One UI 9 its fourth major Android upgrade. The builds it replaces, A346BXXSHFZJ4 in Europe and A346EXXSGFZJ4 in the other markets, were October security updates on One UI 8.5.
Where it's rolling out
- Europe (SM-A346B): all 20 European CSCs in Samfrew's catalogue. That's unlocked phones in the EEA (EUX) and the rest of Europe (EUY), plus the UK, France, Italy, Poland, Portugal, Ireland, Austria, Switzerland, the Czech Republic, Croatia, Slovenia and Serbia.
- Middle East and Africa (SM-A346E): Türkiye, the UAE, Saudi Arabia, Iraq, Israel, Egypt, Libya, Tunisia, Morocco, Nigeria, Ghana, Senegal, Kenya, South Africa and other southern African countries, plus Pakistan and Afghanistan.
- Asia-Pacific (SM-A346E): Australia, New Zealand, Singapore, Malaysia, Indonesia, Thailand, Vietnam and the Philippines.
- Ukraine, Georgia and Kazakhstan (SM-A346E).
Not there yet:
- India, Bangladesh and Nepal (SM-A346E): still on Android 16.
- Latin America (SM-A346M): got October's security update on Android 16, but no One UI 9 yet.
- Taiwan and Hong Kong (SM-A3460): still on Android 16.
As with every big release, not every phone will see the update notification on day one.
How to update
On the phone, open Settings → Software update → Download and install. Rollout timing can vary by country and carrier.
If you'd rather flash it yourself, use firmware that matches your exact model and CSC. A Galaxy phone won't accept firmware with a lower bootloader revision than the one it already runs; this update keeps October's revision. On Samfrew:
Every other CSC is on the SM-A346B and SM-A346E firmware pages. Samfrew's release pages also show a Software details box with the One UI version, security patch and build number read from the firmware.
