Samsung Galaxy A3 (SM-A300G) Firmware Overview
What is the latest SM-A300G firmware?
A300GXXS1BPL1, released October 7, 2020 with Android 4.4.4. It is a security update on bootloader binary 1. The archive holds 20 official builds across 4 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy A3 still getting updates?
Most likely not: there has been no new firmware since October 2020, so Android 5.0.2 is the last version this model got. The final builds below are still the best choice for a clean reinstall.
Which Android versions did it get?
The SM-A300G builds in the archive run Android 4.4.4 to 5.0.2. The earliest build we have for each version:
- Android 5.0.2: A300GXXU1BOF1 (Jun 2015), 13 builds in total
- Android 4.4.4: A300GDXU1AOB1 (Feb 2015), 6 builds in total
Can I downgrade the SM-A300G firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. All decodable builds in the archive share binary 1:
- Binary 1 — since Jan 2015
