Samsung Galaxy A37 5G (SM-A376B) Firmware Overview
What is the latest SM-A376B firmware?
A376BXXS6BZJ1, released October 22, 2026 with Android 17. It is a security update on bootloader binary 6. The archive holds 20 official builds across 20 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy A37 5G still getting updates?
Yes. The newest build is from October 2026, and 11 of 20 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-A376B builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: A376BXXU5BZI6 (Sep 2026), 15 builds in total
- Android 16: A376BXXS5AZI4 (Oct 2026), 5 builds in total
Can I downgrade the SM-A376B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 5 to 6:
- Binary 6 — since Oct 2026
- Binary 5 — since Sep 2026
A phone already on binary 6 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 6 build. How to read a build number.
