Samsung Galaxy S26+ (SM-S947B) Firmware Overview
What is the latest SM-S947B firmware?
S947BXXS4BZIG, released September 29, 2026 with Android 17. It is a security update on bootloader binary 4. The archive holds 132 official builds across 71 regions (CSC).
Is the Samsung Galaxy S26+ still getting updates?
Yes. The newest build is from September 2026, and 29 of 71 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-S947B builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: S947BXXS4BZIG (Sep 2026), 29 builds in total
- Android 16: S947BXXS1AZC7 (Mar 2026), 103 builds in total
Can I downgrade the SM-S947B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 1 to 4:
- Binary 4 — since Jul 2026
- Binary 3 — since Jun 2026
- Binary 2 — since Apr 2026
- Binary 1 — since Mar 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.
