Out of the box: OS build is 12 with One UI Core 4.1; initial security patch for retail units at launch clustered around late 2022. Official over‑the‑air upgrades to OS 13 were released for similar entry models in many regions during 2023, but availability depends on carrier and market.
How to verify and update: open Settings → About phone → Software information to see the current build and security patch date. To pull updates use Settings → Software update → Download and install. Recommended prerequisites before installing a major upgrade: at least 3–5 GB free storage, Wi‑Fi connection, and battery level above 50% or keep the device plugged in. Typical full OTA for a major release ranges from 1.0–2.

Practical recommendations: back up contacts, messages and photos to your Google account or to a PC before upgrading. If performance or battery behavior worsens after an upgrade, clear app caches, check for updated apps in the Play Store, and as a last resort perform a factory reset after backing up data. If an update is delayed in your region, use the official device update tool provided by the vendor or check carrier support pages for rollout schedules.
Identifying the Out-of-the-Box Android Version
Open Settings → About phone → Software information and record the OS release, Build number and Security patch level shown – these three entries reveal the factory-installed system.
-
On-device quick check:
- Settings → About phone → Model number (write it down).
- Settings → About phone → Software information → note: OS release, Build number, Security patch level, Baseband and Kernel versions.
- Take a screenshot of that screen for future reference and warranty/return evidence.
-
ADB check (for users with a PC):
- Enable Developer options and USB debugging.
- Run: adb shell getprop ro.build.version.release
- Run: adb shell getprop ro.build.version.sdk
- Run: adb shell getprop ro.build.id and adb shell getprop ro.build.version.incremental
- Interpretation: the first command gives the user-facing release string, the SDK number is the API level, and build/id/incremental identify the exact factory build.
-
Box and retail metadata:
- Check the retail box sticker for model code, initial firmware label or “software” entry; vendors often print the factory build or release code.
- Use the model code plus region to search official support pages or firmware archives to find the matching initial release and its date.
-
Online firmware lookup:
- Search manufacturer support or well-known firmware repositories using the model number and region/carrier code.
- Match build IDs and release dates – the earliest firmware listed for that model is the out-of-the-box build.
-
Using IMEI/serial on support portals:
- Enter IMEI or serial at the official support lookup page to retrieve exact initial firmware shipped with that unit (if the portal provides firmware details).
Recommendation: record both the numeric release and the SDK/API level plus the build ID. If the factory build is older than the current security patch you expect, apply available over-the-air updates and keep the initial screenshot for comparison after updates.
Check model code and region to determine OS
Confirm the handset’s model code and CSC/region code before installing any system update or custom firmware.
Find the model code and build string: open Settings > About phone > Model number and Build number (or Software information). Record the exact model ID (pattern like SM-XXXX) and the full build name – that build string is the fastest way to identify the shipped operating-system build.
Locate the region/CSC: Settings > About phone > Software information or Service provider fields often show the CSC/region tag (three-letter codes such as BTU, XSG, INS, EUX). If the UI hides it, check the retail box label, purchase receipt, or run an IMEI lookup on a reputable site to get the assigned CSC.
Use targeted lookups: paste the model ID and build string into authoritative sources – the device maker’s support portal, GSMArena device page, XDA Developers forum threads, or firmware repositories – to see which OS build was shipped to that region. Search terms that work well: “modelID firmware”, “modelID CSC”, or “build-string changelog”.
Interpret firmware names: official firmware packages and changelogs typically include a numeric major-release marker (for example “13” or “14”) or a release code in the filename. Match that marker against the build string you recorded to identify the installed major release without guessing.
If the model and CSC indicate a different release than expected, do not flash random files. Use the manufacturer’s official updater tool or the carrier’s OTA channel for your specific model+CSC. Flashing firmware from another CSC can disable local network bands, break carrier features, or void warranty.
Quick checklist: 1) Record model ID + build string. 2) Retrieve CSC/region from Settings, box, or IMEI lookup. 3) Verify against official firmware pages and forum changelogs. 4) Use only region-matching official update tools or authorized service if an update is required.
