Samsung Galaxy A33 5G (SM-A336N) Firmware Overview
What is the latest SM-A336N firmware?
A336NKSUGGZI2, released September 15, 2026 with Android 16. It is a feature update on bootloader binary 16. 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 Galaxy A33 5G 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.
Can I downgrade the SM-A336N firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 12 to 16:
- Binary 16 — since Aug 2026
- Binary 15 — since May 2026
- Binary 14 — since Feb 2026
- Binary 13 — since Jan 2026
- Binary 12 — since Dec 2025
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.
