Samsung Galaxy A3 (SM-A320Y) Firmware Overview
What is the latest SM-A320Y firmware?
A320YDXS8CTJ3, released November 18, 2020 for region EON with Android 8. It is a security update on bootloader binary 8. The archive holds 2 official builds for this region.
Is the Samsung Galaxy A3 still getting updates?
Most likely not: there has been no new firmware since November 2020, so Android 8 is the last version this model got. The final builds below are still the best choice for a clean reinstall.
Can I downgrade the SM-A320Y 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 8:
- Binary 8 — since Oct 2020
- Binary 7 — since May 2020
A phone already on binary 8 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 8 build. How to read a build number.
