Grant Mirror Permission via ADB

Grant Mirror Permission via ADB

Other languages: 繁體中文 | Português (Brasil) | Español | Deutsch

By default, Android displays a permission dialog every time ScreenOnAuto starts screen mirroring. You can pre-grant the Screen Capture (MediaProjection) permission with ADB so the dialog never appears again.

Prerequisites

• ADB (Android Debug Bridge) installed on your computer
• USB debugging enabled on your phone (Settings → Developer options → USB debugging)
• Phone connected via USB (or ADB over Wi-Fi)

Steps

1. Open a terminal (Command Prompt / PowerShell on Windows).

2. Verify ADB can see your device:

   adb devices
   

   Your device should appear as device (not unauthorized).

3. Grant the permission:

   adb shell appops set idv.lzn.screenonauto android:project_media allow
   

4. Launch ScreenOnAuto and start mirroring — the permission dialog should no longer appear.

Revoking the Permission

To restore the default behavior (dialog shown each time):

adb shell appops set idv.lzn.screenonauto android:project_media default

Troubleshooting

• error: device unauthorized — Look for the "Allow USB debugging?" dialog on your phone and tap Allow.
• Dialog still appears — Force-stop ScreenOnAuto and relaunch. If it persists, revoke and re-grant using the commands above.
• Reinstalled the app (or switched between the Play and sideload channels) — uninstalling clears the grant; re-run the grant command after reinstalling.
• Permission resets after reboot — On some ROMs (e.g. MIUI/HyperOS), appops grants don't survive reboots. Re-run the command after each restart, or use ADB over Wi-Fi.
