Short answer: The 5i left the factory on Google’s mobile operating system release 9 (Pie) and many units received an official upgrade to release 10; for a secure and stable experience, accept the maker’s OTA or the official firmware package that matches your device codename.
How to verify your current build: Open Settings → About phone (or System) → Software information. Check the build number and the security patch level; those fields give the exact release number and the most recent monthly patch installed on the handset.
Advanced verification via PC: Enable USB debugging and run adb shell getprop ro.build.version.release to see the numeric OS release, adb shell getprop ro.build.version.sdk for the SDK level, and adb shell getprop ro.build.version.security_patch for the patch date.
Update routes: Use Settings → System → System update for over-the-air updates from the manufacturer. If you download firmware, use only the official support page and the file that matches the 5i codename. For third-party firmware, expect to unlock the bootloader, install a custom recovery, back up data, and accept warranty/security trade-offs.
Support window for this model typically included one major OS upgrade and about two years of security patches; confirm current lifetime and update availability on the manufacturer’s support portal or in device-specific community threads before planning major software changes.
OS Baseline: Android Version Shipped with Realme 5i
Shipped with Google’s mobile operating system 9 (Pie) paired with ColorOS 6.1; apply the available OTA that upgrades the handset to the 10-based UI release to obtain the next major feature set and recent security patches.
Verify current build: Settings → About phone → Software update. Before installing an OTA, back up user data, connect to a stable Wi‑Fi network, and ensure battery level is above 50%. Allow 15–30 minutes for a major upgrade and reboot when prompted.
If an update fails or causes instability, try clearing the system cache via recovery, then reattempt the OTA.

For prolonged platform support, monitor official support pages for the 5i and prefer official firmware or verified vendor images rather than untrusted third-party packages.
Factory Android version
The 5i shipped from factory with build 9.0 (Pie) running ColorOS 6.0; verify this immediately via Settings → About phone → Software information and Security patch level.
To restore the original firmware, back up user data, charge the battery above 50%, then download the official stock package that exactly matches the model code on the box. Apply the package via the device’s Local Update or official recovery/fastboot procedure; do not flash files built for other model codes.
Initial security patch at launch was approximately December 2019; check the security patch date in About phone to confirm factory state. For OTA updates, retain the stock recovery and do not unlock the bootloader if you want to keep receiving official over-the-air releases.
If you plan a custom ROM or rollback, export IMEI and build identifiers first, keep a copy of the stock firmware, and note that unlocking the bootloader typically voids warranty and disrupts future official updates. When in doubt, use the vendor support site for the exact stock image and flashing instructions.
