Samsung SM-A276U Firmware Overview
What is the latest SM-A276U firmware?
A276USQU3BZIF, released September 29, 2026 with Android 17. It is a feature update on bootloader binary 3. The archive holds 20 official builds across 4 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung SM-A276U still getting updates?
Yes. The newest build is from September 2026, and 4 of 4 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-A276U builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: A276USQU3BZIF (Sep 2026), 4 builds in total
- Android 16: A276USQU1AZF1 (Jun 2026), 16 builds in total
Can I downgrade the SM-A276U firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 1 to 3:
- Binary 3 — since Sep 2026
- Binary 2 — since Jul 2026
- Binary 1 — since Jun 2026
A phone already on binary 3 rejects builds with a lower binary in Odin ("SW REV CHECK FAIL"), so it can go back to an earlier Android version only if that version has a binary 3 build. How to read a build number.
