If you’re using a OnePlus Ace 2 Pro 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 OnePlus Ace 2 Pro. In this guide, you’ll learn how to safely install Android 16 on OnePlus Ace 2 Pro and enjoy its latest features.
The OnePlus Ace 2 Pro (2023) is still a very powerful phone thanks to its Snapdragon 8 Gen 2 chipset, UFS 4.0 storage, and up to 24GB RAM. Performance remains excellent for gaming, multitasking, and everyday use, while the 6.74-inch 120Hz AMOLED display is sharp and smooth. One of its biggest highlights is the 150W fast charging, which can take the 5000 mAh battery from near empty to full in around 20 minutes. Even in 2026, it feels fast and responsive.
Its main weakness is the camera system. The 50 MP main camera with OIS is capable of good photos, but the 8 MP ultrawide and 2 MP macro are average, and there is no telephoto lens. It also lacks features now common on newer flagships, such as IP68 water resistance, wireless charging, and longer software support.
Overall, if you want flagship-level performance and ultra-fast charging at a lower price, the OnePlus Ace 2 Pro remains an excellent value choice.
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 OnePlus Ace 2 Pro. 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 OnePlus Ace 2 Pro and your computer. These drivers enable file transfers, flashing, and other operations between your devices.

Unlocking the bootloader of your OnePlus Ace 2 Pro. is essential before you can install any custom ROM. Make sure to follow OnePlus’s official instructions for unlocking the bootloader. Unlocking the bootloader will wipe your device, so back up your data beforehand.

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!

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 OnePlus Ace 2 Pro, you’re extending its life and unlocking modern Android features that OnePlus may never officially provide.
