Samsung Galaxy A27 5G (SM-A276B) Firmware Overview
What is the latest SM-A276B firmware?
A276BXXU3BZIF, released September 29, 2026 with Android 17. It is a feature update on bootloader binary 3. The archive holds 103 official builds across 70 regions (CSC).
Is the Samsung Galaxy A27 5G still getting updates?
Yes. The newest build is from September 2026, and 46 of 70 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-A276B builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: A276BXXU3BZIF (Sep 2026), 20 builds in total
- Android 16: A276BXXS2AZG1 (Jul 2026), 83 builds in total
Can I downgrade the SM-A276B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 2 to 3:
- Binary 3 — since Aug 2026
- Binary 2 — since Jul 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.
