Samsung Galaxy S22 (SM-S901B) Firmware Overview
What is the latest SM-S901B firmware?
S901BXXSOGZH3, released August 18, 2026 with Android 16. It is a security update on bootloader binary 24. The archive holds 81 official builds across 25 regions (CSC).
Is the Samsung Galaxy S22 still getting updates?
Yes. The newest build is from August 2026, and 21 of 25 regions already have a build from that month; the rest usually follow within a few weeks.
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 23 — since Apr 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.
