Samsung Galaxy J3 (SM-J320ZN) Firmware Overview
What is the latest SM-J320ZN firmware?
J320ZNDOU1ARA1, released January 26, 2018 with Android 5.1.1. It is a feature update on bootloader binary 1. The archive holds 20 official builds across 5 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy J3 still getting updates?
Most likely not: there has been no new firmware since January 2018, so Android 7 is the last version this model got. The final builds below are still the best choice for a clean reinstall.
Which Android versions did it get?
The SM-J320ZN builds in the archive run Android 5.1.1 to 7. The earliest build we have for each version:
- Android 7: J320ZNDOU1AQH1 (Sep 2017), 2 builds in total
- Android 5.1.1: J320ZNDOS1AQE2 (May 2017), 16 builds in total
Can I downgrade the SM-J320ZN firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. All decodable builds in the archive share binary 1:
- Binary 1 — since Apr 2016
