Which Android versions did it get?
The SM-A156L builds in the archive run Android 14 to 16. The earliest build we have for each version:

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.
