Samsung Galaxy A33 5G (SM-A336M) Firmware Overview
What is the latest SM-A336M firmware?
A336MUBUKGZI3, released September 16, 2026 with Android 16. It is a feature update on bootloader binary 20. The archive holds 149 official builds across 44 regions (CSC).
Is the Samsung Galaxy A33 5G still getting updates?
Yes. The newest build is from September 2026, and 32 of 44 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-A336M firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 16 to 20:
- Binary 20 — since Aug 2026
- Binary 19 — since Jul 2026
- Binary 18 — since May 2026
- Binary 17 — since Feb 2026
- Binary 16 — since Jan 2026
A phone already on binary 20 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 20 build. How to read a build number.
