Direct answer: The SM‑A025 series left the factory with OS 10 (One UI Core 2.5) and has an official upgrade to OS 11 (One UI Core 3). Official support for additional major releases is limited; expect only security and maintenance updates after the single major upgrade cycle.
Practical checklist before updating: back up contacts and photos; ensure at least 3–4 GB of free internal storage; charge the battery above 50%; connect to a stable Wi‑Fi network; open Settings → Software update and select Download and install. If the OTA is not listed, use the manufacturer’s desktop updater utility or contact carrier support rather than installing unsigned firmware.
Security patch cadence: monthly updates were issued early in the device lifecycle, then shifted to quarterly patches. If you require features from OS 12 or later, plan a hardware upgrade; community builds exist but they require technical skill and void official support.

For day‑to‑day use keep automatic updates enabled and maintain a regular backup schedule to minimize data loss during upgrades.
Do you mean “10 headings”? Please confirm how many sections you want (so I can create each with 4–6 subheadings, with different counts per section).
Recommendation: Use 6 sections. Suggested focus and subheading counts: Section 1 – Hardware & specs (5); Section 2 – Software update cadence & support timeline (4); Section 3 – Performance & benchmarks (6); Section 4 – Connectivity, radios and sensors (4); Section 5 – Battery behaviour & charging (5); Section 6 – Troubleshooting, tips & FAQ (4).
Example subheadings for Section 1 (5): processor model; RAM and storage variants; display type and resolution; camera modules and modes; chassis materials and durability ratings.
Example subheadings for Section 2 (4): current build number and build date; update rollout history; security update schedule; official upgrade path and limitations.
If you prefer 10 sections: use this distribution of subheadings – 4,4,5,5,6,4,5,4,6,4 – with topic blocks such as specs, software lifecycle, performance, connectivity, battery, multimedia, cameras, system tweaks, accessories and compatibility, and troubleshooting.
Action requested: Confirm one of the two options (6 sections with the specified counts, or 10 sections with the proposed distribution), or state the exact number of sections you want and any preferred topic priorities so I can draft each section with 4–6 distinct subheadings.
