Samsung Galaxy F16 5G (SM-E166P) Firmware Overview
What is the latest SM-E166P firmware?
E166PXXS7DZG1, released July 9, 2026 with Android 16. It is a security update on bootloader binary 7. The archive holds 24 official builds across 2 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy F16 5G still getting updates?
Yes. The newest build is from July 2026, and 2 of 2 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-E166P builds in the archive run Android 14 to 16. The earliest build we have for each version:
- Android 16: E166PXXU3CYI9 (Oct 2025), 16 builds in total
- Android 15: E166PXXU2BYE5 (May 2025), 4 builds in total
- Android 14: E166PXXU1AYA5 (Jan 2025), 4 builds in total
Can I downgrade the SM-E166P 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 7:
- Binary 7 — since Jul 2026
- Binary 6 — since Jun 2026
- Binary 5 — since Feb 2026
- Binary 4 — since Jan 2026
- Binary 3 — since Jul 2025
- Binary 2 — since Apr 2025
- Binary 1 — since Jan 2025
A phone already on binary 7 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 7 build. How to read a build number.
