Samsung Galaxy J3 (SM-J327R7) Firmware Overview
What is the latest SM-J327R7 firmware?
J327R7WWS5BTG1, released August 14, 2020 with Android 7. It is a security update on bootloader binary 5. The archive holds 16 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 August 2020, 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-J327R7 builds in the archive run Android 7 to 8.1. The earliest build we have for each version:
- Android 8.1: J327R7WWU4BRJ3 (Oct 2018), 5 builds in total
- Android 7: J327R7WWU1AQF1 (Jun 2017), 9 builds in total
Can I downgrade the SM-J327R7 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 5:
- Binary 5 — since Mar 2019
- Binary 4 — since Jun 2018
- Binary 3 — since Feb 2018
- Binary 1 — since Jun 2017
A phone already on binary 5 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 5 build. How to read a build number.
