This is my first open-source project, created from my real experience using a low-end Android phone with an open EngineerMode system. The purpose of this project is to help others activate full GPU rendering using ANGLE Vulkan without root, through ADB Shell.

Everything here has been tested and tuned carefully, from setprop properties to audio syncing and GPU optimization. I’ve made this as a complete package, not just random tweaks. It’s all explained in detail, step-by-step, and I include video tutorials, screenshots, and downloadable files to make it easier for everyone to follow.

This project goes far beyond just GPU rendering and audio tuning. It covers full system-level optimizations:

Everything is done directly from the phone, without root access or extra devices. No PC, no laptop, not even a virtual cable—just one phone and pure intention.

I just want to share my experience, hoping others who need it can also benefit from it. No clickbait, no complicated tools, no misleading info—just clean, direct help based on real usage.

The entire process of this project—including testing, debugging, scripting, publishing, even creating a GitHub repository—was all done using just one Android phone. No root, no laptop, no PC, no OTG cable, no ADB over network. Purely from one device without USB debugging and such, for everyone.

Thank you for everyone who supports and appreciates this project!
