The Realme C11 2021 was released with Android 11 out-of-the-box. Therefore, the Android 12 should be its first major OS update however there’s no update on it yet.
Hence, we should wait for the official announcement from the company for the Android 12 and Android 13 updates as per the predictions, the device might not be eligible for the Android 13 update but again, that's just a prediction.
