Samsung Galaxy S23+ (SM-S916U) Firmware Overview
What is the latest SM-S916U firmware?
S916USQU8GZIF, released September 30, 2026 with Android 17. It is a feature update on bootloader binary 8. The archive holds 102 official builds across 11 regions (CSC).
Is the Samsung Galaxy S23+ still getting updates?
Yes. The newest build is from September 2026, and 10 of 11 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-S916U builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: S916USQU8GZIF (Sep 2026), 6 builds in total
- Android 16: S916USQS6EYL1 (Dec 2025), 96 builds in total
Can I downgrade the SM-S916U firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 6 to 8:
- Binary 8 — since Jun 2026
- Binary 7 — since Feb 2026
- Binary 6 — since Dec 2025
A phone already on binary 8 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 8 build. How to read a build number.
