Samsung Galaxy J3 (SM-J327R4) Firmware Overview
What is the latest SM-J327R4 firmware?
J327R4TYS2BSD1, released May 3, 2019 with Android 7. It is a security update on bootloader binary 2. The archive holds 15 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 J3 still getting updates?
Most likely not: there has been no new firmware since May 2019, so Android 8.1 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-J327R4 builds in the archive run Android 7 to 8.1. The earliest build we have for each version:
- Android 8.1: J327R4TYU1BRJ1 (Oct 2018), 4 builds in total
- Android 7: J327R4TYU1AQE4 (May 2017), 9 builds in total
Can I downgrade the SM-J327R4 firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 1 to 2:
- Binary 2 — since Apr 2019
- Binary 1 — since May 2017
A phone already on binary 2 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 2 build. How to read a build number.
