USB Display

USB Display allows users to display their Android device screen on a compatible external USB display. It is designed for external USB display applications and compatible USB touch displays.

Connect a compatible USB Display device to your Android device, launch USB Display, and follow the on-screen instructions to start using the external display.

USB Display also supports touch interaction with compatible external USB touch displays. Touch coordinates received from the connected external display are mapped to the corresponding coordinates on the Android device, allowing the user to interact with the Android device directly from the external touch display.

AccessibilityService API Usage

USB Display uses the Android AccessibilityService API as a required component of its external USB touch interaction functionality.

When the user touches a connected external USB touch display, USB Display receives the touch coordinates from the external device, maps them to the corresponding coordinates on the Android device, and uses AccessibilityService to perform the touch action requested by the user.

USB Display uses AccessibilityService only to process and perform touch actions initiated by the user through the connected external USB touch display.

USB Display does not use AccessibilityService to read screen text, buttons, window content, or other on-screen content.

USB Display does not use AccessibilityService to autonomously initiate, plan, or execute actions, and does not make decisions on behalf of the user. Every touch action performed through this functionality originates from the user's physical interaction with the connected external USB touch display.

Data processed for this AccessibilityService functionality is not transmitted to RACER TECH servers, websites, or third-party servers.

AccessibilityService is not enabled automatically. The user must explicitly grant AccessibilityService permission through Android system settings before using USB Display.
