Grant Permissions for Hexnode Apps using Android Debug Bridge (ADB)

Android Debug Bridge (ADB) is a command-line tool that allows a computer to communicate with a connected Android device. It empowers administrators to execute various actions on Android devices, such as installing apps, granting app permissions, and more. This article will walk you through the steps to automatically grant several permissions for the Hexnode apps using Android Debug Bridge.

1. Navigate to Settings > About phone > Software information on the Android device. Next, tap on the Build number seven times to turn on Developer mode.
2. Then, head on to Settings > Developer options and enable USB debugging.
3. Now, install ADB on your computer and download the Hexnode UEM app to the ADB folder.
4. Next, open Command Prompt and navigate to the ADB folder. Enter the below command to start the ADB server:
