EXTENDED KNOWLEDGE

1. What is USB Debugging Mode?

USB Debugging Mode is a mode that can be enabled in Android after you connect the Android device to a computer via a USB cable. This mode is originally used to facilitate a connection between an Android device and a computer Android SDK (software development kit), which is a software suite specially designed to aid in the development of Android apps.
After enabling USB debugging and connecting your Android device to computer, you can transfer data from Android to computer, and vice versa; install and uninstall application on Android; and even read the log data on Android.
By default, access to the USB Debugging Mode option is hidden. To enable it, you should tap the "Build number" seven times quickly to activate "Developer Option" and then, you can check the box next to "USB debugging" to enable it.

2. Why we need to enable USB debugging?

It is necessary to distinguish USB Debugging Mode from MTP:
1) If you only need to transfer data between an Android phone and a computer, you just need to turn on the MTP mode.
2) If you want to have a full control on your Android device, such as installing apps, backing up data, rooting Android, etc., you need to enable USB Debugging Mode.

3. The Authority of USB Debugging Mode

After enabling USB debugging on your Android phone, you can connect it to PC and the PC will have an ultimate control over the phone. It can read all kinds of data stored in the phone, install apps, root Android and even break the lock screen password with some downloaded software.

4. What is the difference of the USB Debugging Authority between Android and iOS?

Once you built the connection between Android and PC, on one hand, the computer can read data stored on Android (copy data from Android to PC, and import data from PC into Android). On the other hand, you can use your phone to download pictures or run apps during the connection.
