Immediate recommendation: Install the latest official Google mobile OS update available for this A-series midrange device – aim for at least OS 12 (One UI 4.x) to obtain current security patches and stability fixes; upgrade to OS 13 (One UI 5) where the release is offered by your carrier or region.
The handset shipped with Google’s mobile OS 11 paired with One UI 3.x. Official firmware rollouts have delivered OS 12 to most markets; OS 13 availability is region- and carrier-dependent. Build identifiers follow the OS mainstream codenames (OS 11 → R, OS 12 → S, OS 13 → T) and One UI numbering maps to those major releases (One UI 3.x → OS 11, One UI 4.x → OS 12, One UI 5 → OS 13).
To verify the installed software, open Settings → About phone → Software information. To update, go to Settings → Software update → Download and install. Before applying a major upgrade: back up user data, connect to a stable Wi‑Fi network, ensure battery is above 50%, and allow 20–40 minutes for the process depending on the update size.
If your carrier or region has not released a needed update and you require newer features or longer support, evaluate community-maintained firmware (for example, well-known custom builds) after confirming the device codename and unlocking the bootloader. Flashing third-party ROMs can void warranty and introduce instability; prepare a full device backup, follow trusted forum guides, and use a recovery + root workflow only if you accept those trade-offs.
Original OS at Launch
Install the newest firmware immediately; the handset left the factory running Google’s mobile OS 11 together with One UI 3.1.
- Launch date: June 2021 (global retail availability).
- Factory software image: Google mobile OS 11 (R-series baseline, build prefixes commonly start with RP1A).
- User interface layer: One UI 3.1 on most SKUs; some regional or budget variants shipped with a trimmed One UI 3.1 Core.
- Typical initial security patch: mid-2021 monthly level (check Software information for exact patch date on your unit).
- How to verify original firmware: Settings → About phone → Software information → OS version / Build number (look for RP1A-style identifiers to confirm the R-level baseline).
Recommended immediate actions:
- Back up personal data before applying updates.
- Check Settings → Software update and install any available system and security patches; carrier-locked units may receive updates later than unlocked units.
- If restoring factory image is required, download the official regional firmware from the manufacturer’s support site or use the maker’s desktop software to re-flash the original build–match the exact model code (SM-xxxxx) and region to avoid mismatches.
Notes on variants: 4G and 5G hardware revisions used different base firmware trees; do not cross-flash between 4G and 5G files. Always confirm model code and CSC/region before altering system software.
Android version shipped
This handset left the factory running OS level 11 with One UI 3.1; if purchasing second‑hand, update to the latest OTA and security patch before adding accounts or restoring backups.
To confirm the exact build, open Settings → About phone → Software information and check the OS release line plus the One UI/skin entry. Regional and carrier firmware will show different build codes even while the base OS number remains 11.
Apply outstanding updates via Settings → Software update over Wi‑Fi; keep battery above 50% or connect a charger and back up data (cloud or local) prior to installing major upgrades.

Install only official over‑the‑air files or vendor desktop utilities to preserve device certification and receive security patches.
Note firmware behaviour: 4G and 5G SKUs shipped from the factory with the same OS baseline but can diverge in UI tweaks, preinstalled apps and update timing. Consult the vendor support pages or carrier notices for exact rollout schedules for your specific model and region.
