Your Android desktop,
on the car screen.
KoalaMirror gives the factory Android Auto head unit its own Android display — not a copy of your phone's screen. Any app on the dash, phone free, screen off if you like. No custom ROM, no flashing, no laptop.
Full Android on the car screen
Your phone stays yours
The car has its own desktop. Use your phone separately or turn its screen off while projection continues.
Supported root setups
Works with Magisk, KernelSU and APatch. If Zygisk is missing, deployment installs ReZygisk for you.
Your Android apps
Use navigation, music, video and messaging apps on the car screen, beyond Android Auto's app list.
Private by design
Minimal diagnostics and signed remote config. Your files, contacts, and messages never leave the phone.

Rotary knobs, D-pads and steering-wheel buttons, not just touch.
Rotary and D-pad head units
The dial steps through items on the projected screen, the four-way nudge switches areas, the center press opens.

Button shortcuts
Press a button on the wheel and KoalaMirror learns its signal — one action on tap, another on long press.
Back, Home and Recents
The navigation bar lives inside Android Auto's interface, not floating above it — so a rotary knob can reach it.
Android Auto split view
Prefer Android Auto's split view? Turn the layout rewrite off in Mirror settings — the navigation buttons stay.
Unmapped buttons keep their Android Auto behavior. Rotary movement, D-pad navigation, confirm and back stay reserved for navigation and cannot be reassigned.
Three steps to the car
Install and deploy from your phone. No computer needed.
Start with a rooted phone

Install & deploy
Install KoalaMirror, tap Deploy and reboot once. The app sets up the module for you.

Plug into Android Auto as usual — your desktop appears on the head unit.

Common questions
Do I need root?
Yes. KoalaMirror runs with root and needs a Zygisk runtime. Magisk works out of the box; on KernelSU or APatch, the app auto-provisions ReZygisk during deploy.
Do I need a custom ROM or to flash anything?
No. KoalaMirror is a regular APK. Install it, tap Deploy, reboot once — the app provisions everything by itself. No flashing zips, no command line, no computer.
Does it work with my car?
If your car or aftermarket head unit runs Android Auto, KoalaMirror can project to it. It rides on the standard Android Auto connection your car already supports — nothing is installed on the car side.
Can I map my steering-wheel or head-unit buttons?
Yes, with full features. KoalaMirror detects the button you press and lets you assign one action on tap and another on long press — projected Home, Recents, Back, opening a specific app, or running a root command. Buttons you leave unmapped are passed to Android Auto unchanged.
