When to revoke USB debugging access?

When you connect your Android smartphone to a computer via USB cable, you will be asked whether or not you would allow the computer to access your phone’s system. If you deny access, the connection remains closed and the computer won’t be able to access your phone’s internal storage even when connected. If you allow access, the computer will be able to access your phone’s system. 

By then, your computer would be all set to view and manage files from any of your phone’s system directories. Keeping this setup is only ideal for trusted computers. Revoking USB debugging access is therefore recommended to void all prior access you’ve granted to your Android device.

And that’s all about revoking USB debugging authorizations on the new Samsung Galaxy Z Flip 4 smartphone
