Yes. The newest build is from August 2026.
Can I downgrade the SM-A336M 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 20:
- Binary 20 — since Aug 2026
- Binary 19 — since Jul 2026
- Binary 18 — since May 2026
- Binary 16 — since Jan 2026
A phone already on binary 20 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 20 build. How to read a build number.
