Samsung Galaxy M23 5G (SM-M236B) Firmware Overview
What is the latest SM-M236B firmware?
M236BXXUEEZF3, released July 7, 2026 with Android 14. It is a feature update on bootloader binary 14. The archive holds 42 official builds across 26 regions (CSC).
Is the Samsung Galaxy M23 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-M236B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 13 to 14:
- Binary 14 — since Feb 2026
- Binary 13 — since Dec 2025
A phone already on binary 14 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 14 build. How to read a build number.
