Samsung Galaxy Buddy3 (SM-A156L) Firmware Overview
What is the latest SM-A156L firmware?
A156LKSUAEZJC, released October 19, 2026 with Android 17. It is a feature update on bootloader binary 10. The archive holds 12 official builds across 1 region (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy Buddy3 still getting updates?
Yes. The newest build is from October 2026.
Which Android versions did it get?
The SM-A156L builds in the archive run Android 14 to 17. The earliest build we have for each version:
- Android 17: A156LKSUAEZJC (Oct 2026), 1 build in total
- Android 16: A156LKSU6CYIA (Oct 2025), 8 builds in total
- Android 15: A156LKSU5BYE3 (May 2025), 2 builds in total
- Android 14: A156LKSS5AYB1 (Mar 2025), 1 build in total
Can I downgrade the SM-A156L firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 5 to 10:
- Binary 10 — since Apr 2026
- Binary 9 — since Feb 2026
- Binary 8 — since Jan 2026
- Binary 7 — since Dec 2025
- Binary 6 — since Aug 2025
- Binary 5 — since Feb 2025
A phone already on binary 10 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 10 build. How to read a build number.
