What Is USB Debugging?
Debug mode allows users to access the inner workings of their Android device on a computer via a USB connection. Turning on USB debugging is required to use the Android software develop kit (SDK), which programmers use to build and test new apps. It also permits users to send advanced commands to their phones from their computers with the Android Debug Bridge (ADB). That said, there are several reasons why average users would want to enable debug mode. For example, you can:
Root your Android device so you can install a different operating system. Use ADB to install APK files from your computer and push other commands over USB connection. Use Fastboot to recover a bricked Android device. Make a backup copy of all of your data using the Android SDK.
How to Enable USB Debugging on Android
Enabling debug mode requires access to the developer options menu, which is hidden in your system settings.
How to Disable USB Debugging on Android
To turn off USB debugging, return to the Developer options menu and tap the USB debugging toggle switch again. To reset which computers can access your Android device in debug mode, return to the Developer options menu and tap Revoke USB debugging authorizations.
Security Risks of USB Debugging
Putting your device in debug mode leaves it more vulnerable to malware and outside attacks. For this reason, you’ll receive a security prompt each time you connect your device to a new PC. Avoid plugging your device into public charging ports or using public Wi-Fi networks with debug mode enabled. If you lose your device with debug mode turned on, a tech savvy thief could access your personal data without knowing your passwords. Therefore, you should always turn off debugging when you don’t need it.
Android Debugging Apps
There are apps available in the Google Play store that purportedly make it easier to enable USB debugging; however, considering how simple the process already is, there’s no reason to download an app for this purpose.
How to Enable USB Debugging With a Broken Screen
If your Android’s touchscreen is broken, yet you can still see the display, it may be possible to use a mouse to activate debug mode, provided your device supports On-The-Go (OTG) technology. If it does, connect a mouse via an OTG cable to navigate your device settings without using the touch screen.
