Samsung Galaxy A23 5G (SM-A236U1) Firmware Overview
What is the latest SM-A236U1 firmware?
A236U1UESHEZI6, released September 17, 2026 with Android 14. It is a security update on bootloader binary 17. The archive holds 21 official builds across 18 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy A23 5G still getting updates?
Yes. The newest build is from September 2026, and 18 of 18 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-A236U1 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 17:
- Binary 17 — since Sep 2026
- Binary 16 — since Aug 2026
A phone already on binary 17 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 17 build. How to read a build number.
