Device Faker Zygisk Module: Per-App Device Spoofing Guide

Device Faker is a Zygisk-based root module designed to spoof device specifications, build properties, and CPU data on a per-app basis. Written in Rust, it uses Copy-On-Write memory mapping to isolate fingerprint modifications without altering global system files or requiring a full system reboot.

Testing this module across various apps, I noticed how cleanly it isolates changes per package using its COW property engine without leaving active background processes. Applying high-end device templates to unlock restricted app features took seconds, requiring only a simple app restart rather than rebooting Android entirely.

Core Features

• Per-app targeting allows you to apply spoofed specs only to selected applications while keeping the rest of your system untouched.
• Built-in WebUI simplifies managing templates, tweaking TOML settings, and assigning phone profiles across multiple packages.
• Memory-mapped property engine alters system props via Copy-On-Write (COW), providing isolated changes per process with zero persistent module footprint.
• Per-app CPU spoofing customizes /proc/cpuinfo output to bypass strict hardware checks without editing core system files.

Support & Requirements

• Root Environment: Magisk, KernelSU, or APatch (Zygisk environment required)
• Android Compatibility: Android 10 and above

How to Install

1. Download the latest Device Faker zip release file.
2. Open your root manager (Magisk, KernelSU, or APatch), head to the Modules section, and flash the zip.
3. Reboot your phone to activate the Zygisk module and launch the WebUI for setup.
