Samsung Galaxy M33 5G (SM-M336B) Firmware Overview
What is the latest SM-M336B firmware?
M336BXXUGGZF2, released July 3, 2026 with Android 16. It is a feature update on bootloader binary 16. The archive holds 65 official builds across 26 regions (CSC).
Is the Samsung Galaxy M33 5G still getting updates?
Yes. The newest build is from July 2026, and 1 of 26 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-M336B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 15 to 16:
- Binary 16 — since Feb 2026
- Binary 15 — since Jan 2026
A phone already on binary 16 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 16 build. How to read a build number.
