Samsung Galaxy S22 (SM-S901B) Firmware Overview
What is the latest SM-S901B firmware?
S901BXXSOGZH3, released August 18, 2026 for region MOB with Android 16. It is a security update on bootloader binary 24. The archive holds 3 official builds for this region.
Is the Samsung Galaxy S22 still getting updates?
Yes. The newest build is from August 2026.
Can I downgrade the SM-S901B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 21 to 24:
- Binary 24 — since Aug 2026
- Binary 22 — since Feb 2026
- Binary 21 — since Jan 2026
A phone already on binary 24 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 24 build. How to read a build number.
