InstaShare 2

InstaShare 2 is an app designed for seamless wireless presentation and collaboration, enabling smooth streaming of media files and 4K videos. Users can mirror their display to BenQ displays and control content from PCs, tablets, and smartphones.

Touchback, powered by the TouchFeedback For Instashare 2 accessibility service, lets you control the phone from the large display. To enable it: open Settings, tap the prompt to go to Accessibility, locate TouchFeedback For Instashare 2 in Installed apps/services, and enable. Once enabled, you can perform touch gestures on the display to control your device. If you choose not to enable this service, screen casting remains functional but remote control is unavailable. Privacy: the app uses the AccessibilityService API only to send gestures and explicitly disables window content retrieval, so it cannot read text or sensitive information from your screen.
