The device comes with Helio G70, the only smartphone in this segment to sport this powerful chipset. The device came out of the box with Android 10 under Realme UI 1.0 skin.

Realme C3 Overview

The Realme C3 sports a 6.52-inch IPS LCD display with a resolution of HD+ i.e. it has a resolution of 720×1600 pixels and with a waterdrop notch. The display has a pixel density of 269 pixels per inch ( PPI ) and with an aspect ratio of 20:9. This display has also come with a Corning Gorilla Glass protection. Underneath the Realme C3, it sports the latest octa-core MediaTek Helio G70 chipset; this chipset has awesome capabilities. Coming to the internals of this octa-core G70 SoC, it has two Cortex-A75 cores which clock at 2GHz and to the rest it has six Cortex-A55 cores which clocks at 1.7GHz. This SoC is built on the 12nm process and this SoC is a major upgrade over the Helio P22 which was inside the Realme C2.

Further, the device pairs with 3GB and 4GB of RAM. It has either 32GB or 64GB internal storage options. This internal storage is also further expandable via a micro SD card slot up to 256GB. The device has a dedicated SIM card slot, unlike the hybrid SIM card slot which we have seen on many devices. In this type of SIM card slots, we can insert two Nano type SIM cards and at the same time a micro SD card too.

Coming to the optics department, the Realme C3 sports a dual rear camera setup. This rear camera setup packs a 12MP primary sensor with an f/1.8 aperture value and a pixel size of 1.25-micron. For assisting this sensor, there is a secondary 2 MP sensor with an f/2.4 aperture value and a pixel size of 1.75-micron. The camera on Realme C3 will offer features like Chroma Boost, slow motion video recording, HDR, and panorama selfie. To the front, the device sports a 5 MP sensor that will be used for selfies and video calling.

The Realme C3 packs a 5,000 mah battery and still has a micro USB port. We don’t know when will Realme start using USB type C port in their budget smartphones. And this battery doesn’t come with support for fast charging. The device runs on the latest Android 10 which is based on Color OS 7. Connectivity options on the Realme C3 include Wi-Fi 802.11 b/g/n, GPS, Bluetooth v5.00, USB OTG, Micro-USB, FM radio, Wi-Fi Direct, 3G, and 4G (with support for Band 40 used by some LTE networks in India) with active 4G on both SIM cards.

Android 13 and Its Features

Google has finally started rolling their stable Android 13 update to the public. As expected, only Google has released the update to their Pixel lineup, but no OEM has started cooking a stable yet.

Regarding the Android 13, it seems that the Android 12’s successor has plenty of additional features and improvements to its predecessor. We’ve already seen and used the major UI and design element changes in Android 12 last year, known as ‘Material You.’ This materialistic theming design enhanced the Android user experience from the minimal subtle look, rounded corners, improved pop-ups, etc.

Whereas the improved scrolling screenshots, optimized one-handed UI mode, better privacy & security features, improved app notifications, per-app basis language preferences, app permissions to send notifications, BT LE Audio support, auto theme icons, updated now playing widget, etc. Users will also find intuitive QR scanner support, enhanced silent mode, tap-to-transfer media controls, multiple profiles for NFC payments, and more.

How to Install AOSP Android 13 on Realme C3 (RMX2020)

Pre-Requisites

Before we begin with this procedure, I would strongly recommend you create a backup of your device storage and all your files stored on your device. Moreover, following the steps mentioned in this post carefully is advised to avoid permanent damage or bricking your device.

It’s highly recommended to charge your handset before unlocking the bootloader to avoid your device from shutting down occasionally while going through the process. Make sure to keep at least 50% of charge or higher for a smooth operation.

Using the ADB and Fastboot command (platform-tools), you’ll be able to boot your Android device into the bootloader mode (download mode), which will be easy for you to proceed with further steps. ADB (Android Debug Bridge) creates a connection or bridge between the device and computer to sideload files.

Fastboot is a more advanced command utility tool for Android devices that works with computers. You can download ADB and Fastboot Binaries (Platform-Tools).

Download Realme USB Drivers

A USB Driver is a set of files that allows you to create a successful and strong connection between a mobile device with a computer properly using a USB data cable. It’ll be useful to transfer files between the connected devices, flash files on the handset, and more.

It’s also worth mentioning that mobile devices and other external devices can use and run USB Drivers on a Windows computer. Such as a mouse, keyboard, printer, external hard drives, speakers, USB flash drives, etc. You can grab Realme USB Drivers here.
