Samsung Galaxy S25 Edge (SM-S937N) Firmware Overview
What is the latest SM-S937N firmware?
S937NKSSBDZJ2, released October 7, 2026 with Android 17. It is a security update on bootloader binary 11. The archive holds 24 official builds across 4 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy S25 Edge still getting updates?
Yes. The newest build is from October 2026, and 4 of 4 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-S937N builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: S937NKSUADZIF (Sep 2026), 8 builds in total
- Android 16: S937NKSS8CZE1 (May 2026), 16 builds in total
Can I downgrade the SM-S937N firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 8 to 11:
- Binary 11 — since Oct 2026
- Binary 10 — since Aug 2026
- Binary 9 — since Jul 2026
- Binary 8 — since May 2026
A phone already on binary 11 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 11 build. How to read a build number.
