What is the latest SM-F958N firmware?
F958NKSS4EZJ1, released October 12, 2026 with Android 17. It is a security update on bootloader binary 4. The archive holds 11 official builds across 1 region (CSC).
Is the Samsung Galaxy Z Fold Special Edition still getting updates?
Yes. The newest build is from October 2026.
Which Android versions did it get?
The SM-F958N builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: F958NKSU4EZIH (Sep 2026), 2 builds in total
- Android 16: F958NKSS2CZA1 (Jan 2026), 8 builds in total
Can I downgrade the SM-F958N 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 4:
- Binary 4 — since May 2026
- Binary 3 — since Feb 2026
- Binary 2 — since Jan 2026
A phone already on binary 4 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 4 build. How to read a build number.
