AG Mouse app will let you use your phone as the air mouse for Samsung DeX mode with TV or monitor (not for Samsung Dex app for PC).

Features:
- Mouse cursor movement follows the movement of your phone
- Three basic mouse buttons: Left, Middle, Right (scroll up/down by swiping up/down on "Middle" button)
- Automatically launching and closing app when DeX mode is started and stopped
- Pinch-to-zoom on bottom half of app area to switch between "full screen" app to "mini floating" app window and vice versa

This app does not require root access.

This app uses AccessibilityService API to read gyroscope sensor data to navigate the mouse cursor on the screen as the app feature. By pressing "Allow" button in the "Ask for permission" dialog when opening this app, user allows this app to use AccessibilityService API. Otherwise, pressing "Exit" button to deny and stop using it.

This app requires the API from Shizuku app. So user need to install Shizuku app on Google Play store as specified in below link.
Shizuku app: https://play.google.com/store/apps/details?id=moe.shizuku.privileged.api

The recommendation is to use this app for Samsung phones with the supporting DeX mode on Android 11 or newer because it was tested very carefully on these devices and Android versions. However, the app can still work for other devices like Google Pixel... and other lower Android versions but not all of devices and Android versions were tested. (Please be noted that before buying it and please don't give bad comments/ratings due to using it on unrecommended devices and Android versions. Please email me if you need any technical support for using this app. Thanks)
