Samsung Galaxy Z Fold4 (SM-F936B) Firmware Overview
What is the latest SM-F936B firmware?
F936BXXSCIZF1, released June 12, 2026 for region MM1 with Android 16. It is a security update on bootloader binary 12. The archive holds 2 official builds for this region.
Is the Samsung Galaxy Z Fold4 still getting updates?
Yes. The newest build is from June 2026.
Can I downgrade the SM-F936B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 10 to 12:
- Binary 12 — since Jun 2026
- Binary 10 — since Jan 2026
A phone already on binary 12 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 12 build. How to read a build number.
