Immediate verification steps: open Settings → About phone → Software information and record three items: the platform release name, the build string shown as "Build number" and the Security patch level (displayed as YYYY‑MM‑DD). Also copy the Model number and IMEI from the same screen.

These four values are the minimal checklist to validate any vendor file you download.

Safe install prerequisites: connect to a reliable Wi‑Fi, free at least 3–4 GB of internal storage, back up apps and data to cloud or local PC, and deactivate screen lock/FRP if you will flash manually. Use the device's Local upgrade or recovery option to apply full packages; prefer automatic over‑the‑air delivery when available because it preserves user data in most cases.

Manual flashing notes: download only the package that exactly matches your Model number, verify the package checksum (MD5 or SHA‑256) before flashing, and do not proceed if the checksum or model mismatch. If a bootloader unlock is required, export accounts and keys first – unlocking clears user data. Keep at least one full backup copy off the handset in case rollback is needed.

Maintenance guidance: check the Security patch level date frequently; devices released in 2020 typically receive major platform upgrades for one to two cycles and security patches for roughly two to three years. If the patch date on your C3 is older than 2022‑06, prioritize applying an official cumulative package from the vendor site or an authorized service center.

Current Android version on Realme C3

Keep the C3 on the latest official firmware: platform level 10 with the manufacturer's UI 1.0 skin; the last security patch for the model was released in March 2021 and the vendor has not issued an official platform uplift to level 11 for this handset–only third‑party builds provide newer platform images.

Verify build and patch level via Settings → About phone → Build number / Security patch level and compare those entries with the device page on the manufacturer's support site. To install an official package, download the full or incremental firmware to internal storage root and apply it through Settings → About phone → Local install (backup user data first, keep battery >50% and use Wi‑Fi). Avoid unofficial packages unless you accept bootloader unlocking, warranty voidance and potential instability; retain the vendor rollback package to restore stock when needed.

Original Android version at launch

Use the factory build based on platform 10 (codename Q) with ColorOS 7.0 that shipped on the C3 when you need the stock software state and full manufacturer support.

Device launch: announced in early February 2020 and distributed out-of-the-box with the platform 10 base and the vendor's ColorOS 7.0 skin; commercial model code is RMX2020 and initial security patch dates fall in early 2020.

To restore or confirm the factory build, download the full firmware package for RMX2020 from the official support site, verify the file checksum (SHA256), then apply via the vendor recovery or the official flashing utility. Backup all personal data first, ensure battery >60%, and use a reliable USB cable and a stable PC connection.

Avoid flashing images meant for other model codes. Unlocking the bootloader will erase data and may void warranty; unofficial packages can break Widevine L1, banking apps and safety features. If you require later platform releases, obtain them only through the manufacturer's channels or the device updater to preserve security and certification.
