Samsung Galaxy A31 (SM-A315G) Firmware Overview
What is the latest SM-A315G firmware?
A315GDXU5DXJ4, released October 5, 2024 with Android 12. It is a feature update on bootloader binary 5. The archive holds 20 official builds across 20 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy A31 still getting updates?
Most likely not: there has been no new firmware since October 2024, so Android 12 is the last version this model got. The final builds below are still the best choice for a clean reinstall.
Can I downgrade the SM-A315G firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. All decodable builds in the archive share binary 5:
