Samsung SM-J337R7 Firmware Overview
What is the latest SM-J337R7 firmware?
J337R7WWUABUJ2, released November 30, 2021 with Android 9. It is a feature update on bootloader binary 10. The archive holds 16 official builds across 1 region (CSC).
Is the Samsung SM-J337R7 still getting updates?
Most likely not: there has been no new firmware since November 2021, so Android 9 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-J337R7 builds in the archive run Android 8 to 9. The earliest build we have for each version:
- Android 9: J337R7WWU4BSG1 (Jul 2019), 12 builds in total
- Android 8: J337R7WWU2ARK2 (Nov 2018), 4 builds in total
Can I downgrade the SM-J337R7 firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 2 to 10:
- Binary 10 — since Jul 2021
- Binary 9 — since Oct 2020
- Binary 8 — since Jun 2020
- Binary 7 — since May 2020
- Binary 6 — since Dec 2019
- Binary 5 — since Oct 2019
- Binary 4 — since May 2019
- Binary 3 — since Feb 2019
- Binary 2 — since Nov 2018
A phone already on binary 10 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 10 build. How to read a build number.
