Samsung Galaxy A15 5G (SM-S156V) Firmware Overview
What is the latest SM-S156V firmware?
S156VUDSDEZJ4, released October 6, 2026 with Android 16. It is a security update on bootloader binary 13. The archive holds 20 official builds across 2 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy A15 5G still getting updates?
Yes. The newest build is from October 2026, and 2 of 2 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-S156V firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 7 to 13:
- Binary 13 — since Oct 2026
- Binary 12 — since Jul 2026
- Binary 11 — since Apr 2026
- Binary 10 — since Feb 2026
- Binary 9 — since Jan 2026
- Binary 8 — since Dec 2025
- Binary 7 — since Sep 2025
A phone already on binary 13 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 13 build. How to read a build number.
