I started my career as a blogger in 2014 and also worked on an Android niche platform to gain extra income. I cover the topic on How to guides, software updates, Custom ROM updates and also product review. I'm 24 years old, completed MBA (Master of Business Administration) from Sikkim Manipal University.
If you’re using a Realme C3 and want to breathe new life into your device, installing an Android 16-based custom ROM is a solid move. Google recently released Android 16 for Pixel devices, and developers have already ported unofficial AOSP builds to older phones like the Realme C3. In this guide, you’ll learn how to safely install Android 16 on Realme C3 and enjoy its latest features.
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 16 introduces Material 3 Expressive, a refined evolution of Google’s design language for smartphones and tablets. While it doesn’t completely reinvent the interface, it represents one of the most noticeable user-facing changes in the OS. Rather than a dramatic visual overhaul, Material 3 Expressive enhances the foundation laid by Material Design 3 by introducing smoother, more dynamic animations, larger touch targets, and bolder typography.
This update arrives at a perfect moment. Material Design 3, first introduced with Android 13, had begun to feel dated. Material 3 Expressive breathes new life into the interface while preserving the familiar look and feel users have grown comfortable with. Instead of overhyping the changes, Google’s own animations showcase the polish and fluidity of this next step in Android design.
Android 16 introduces a wealth of new features, system optimizations, and UI refinements. Some of the highlights include:
These updates aim to improve user experience across different types of devices, including foldables, tablets, and standard phones.
Although Android 16 is rolling out first to Pixel devices, many brands like Xiaomi, OnePlus, Samsung, Realme, and others will follow soon. If you’re impatient, a custom ROM is the best way to get Android 16 today.
Everything seems to be working fine.
If you spot any bugs, report them along with proper logs to the developer.
Always back up your device before flashing any ROM. This prevents data loss if anything goes wrong. Backup guide here.
Charge your phone to at least 50% to avoid shutdowns during the flashing process.
You can skip this part if you have already installed TWRP Recovery on your Realme C3. For those who haven’t, ADB and Fastboot commands (platform-tools) are required to boot your device into bootloader mode, allowing you to perform the necessary flashing operations. ADB (Android Debug Bridge) establishes a connection between your device and computer, while Fastboot is a more advanced command-line utility for flashing and modifying Android devices.
You can download the ADB and Fastboot Binaries (Platform-Tools) here.
You’ll need the appropriate USB drivers to ensure a successful connection between your Realme C3 and your computer. These drivers enable file transfers, flashing, and other operations between your devices.
You can download the latest Realme USB drivers here.
Unlocking the bootloader of your Realme C3. is essential before you can install any custom ROM. Make sure to follow Xiaomi’s official instructions for unlocking the bootloader. Unlocking the bootloader will wipe your device, so back up your data beforehand.
You must install TWRP Recovery on your phone to install any custom ROM on your device. After unlocking the bootloader, follow our guide to install TWRP Recovery on your Realme C3.
You can download the Android 15 custom ROMs for the Realme C3 from the links below:
| OS | Download Link |
| CrDroid OS | Download |
| YAAP OS | Download |
Most AOSP ROMs don’t come with Google apps. You’ll need to flash Android 16 GApps separately.
Note: Flash GApps right after flashing the ROM. Don’t reboot in between.
Warning!
GetDroidTips is not responsible for any issues that may happen to your device if you flash it on another device and brick it. Do it at your own risk.
adb reboot recovery
The first boot after installing a custom ROM may take a bit longer than usual, so don’t panic if it seems slow. After the device boots, you will need to set it up as a new device, just like when you first got it.
By flashing Android 16 on your Realme C3, you’re extending its life and unlocking modern Android features that Xiaomi may never officially provide. While this is an unofficial AOSP build, early reports suggest solid stability. That said, bugs may still appear, so always report them with logs to help developers improve the experience.
If you have questions or run into issues during installation, feel free to drop a comment. Enjoy your fresh Android 16 experience!
