Samsung Galaxy A15 (SM-A155F) Firmware Overview
What is the latest SM-A155F firmware?
A155FXXSCEZH3, released August 26, 2026 with Android 16. It is a security update on bootloader binary 12. The archive holds 103 official builds across 45 regions (CSC).
Is the Samsung Galaxy A15 still getting updates?
Yes. The newest build is from August 2026, and 20 of 45 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-A155F firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 9 to 12:
- Binary 12 — since Aug 2026
- Binary 11 — since Jul 2026
- Binary 10 — since Feb 2026
- Binary 9 — since Jan 2026
A phone already on binary 12 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 12 build. How to read a build number.
