Short answer: the device shipped with Google’s mobile operating system 9 (Pie) and received an official upgrade to Google’s mobile operating system 10 paired with One UI 2.0; there is no official build from the manufacturer for Google’s mobile operating system 11.
Out of the box the unit came with One UI 1.x layered over the base OS 9 (Pie). The official firmware roll-out to OS 10 arrived in mid‑2020 for most regional variants (check your model code SM‑A207F). After the OS 10 update, the device continued to receive periodic security patches for roughly 12–18 months depending on carrier and region.
To verify your current software: open Settings → About phone → Software information to see the build number and base OS level. To fetch official updates use Settings → Software update → Download and install. Before applying a major update, ensure at least ~3 GB of free internal storage, battery above 50% (or connect the charger), and create a full backup (cloud or local) of contacts, photos and apps.
If you need a newer major release than OS 10, vetted community builds (LineageOS, Pixel Experience and similar) are the primary path for this model; search for builds explicitly supporting SM‑A207F. Unlocking the bootloader and flashing custom firmware voids warranty, erases data, and can introduce instability – proceed only if comfortable with those risks and follow device‑specific installation guides.
Recommendation: keep the handset on the latest official OS 10 firmware with the most recent security patches available for your region. Pursue third‑party builds only after confirming active support for SM‑A207F on trusted developer sites and after making a complete backup.

Factory firmware rollout occurred around September 2019; the out-of-box build includes One UI 1.1 and the security patch level contemporaneous to that release. Confirm the original build by opening Settings > About phone > Software information and checking Base OS, Build number and Security patch level.
To receive later platform upgrades and monthly fixes, check Settings > Software update > Download and install or consult the manufacturer’s support portal using your exact model code and region/CSC. When acquiring a used unit, prefer devices already updated to at least the 10.0 major release for stronger security; avoid unofficial firmware unless you can back up data and follow reliable flashing instructions.
Original Android version at release
First action: open Settings → About phone → Software information and write down the model code, build ID and the OS base label before applying updates or flashing firmware.
- How to read originals: Settings → About phone → Model number (example format SM‑A207x), Software information → OS version and One UI Core entry; note the CSC/region code for correct firmware matching.
- Before updating: back up full device image (cloud or desktop tool), connect charger or keep battery ≥50%, use a stable Wi‑Fi, and free at least 3 GB of internal storage to avoid update failures.
- Security and app compatibility: devices left on the factory platform miss newer security patches and may fail to install apps that require later API levels; install available system updates immediately or limit sensitive activities until patches are applied.
- If you plan to reflash stock firmware or install custom builds: download files only from official support portals or well‑known firmware archives, verify the build corresponds exactly to your model code and CSC, and expect a full data wipe and potential warranty effects.
- Troubleshooting update issues: clear temporary cache in recovery mode, retry update via desktop companion tool if OTA stalls, and collect model/build data to provide to support if problems persist.
- When in doubt, contact manufacturer support with the model code, build number and current security patch date to get authoritative guidance on update eligibility and available upgrade paths.
