USB debugging expands our possibilities when we connect Android to our computer via the USB cable. It is not necessary to do this if we just want to transfer files between both computers, but it is necessary to use ADB software and be able to send commands from the PC. This is more important than it seems, because when there is a problem with the mobile phone, this procedure can allow us to create a backup of the device, install APKs, restart or restore the mobile phone, control it by on the PC if the screen is broken and much more.
Enabling USB debugging is a very simple process. Just access your Android system settings and tap here and there. After activating and connecting the mobile phone to the computer with the USB cable, you will see a «Allow USB troubleshooting» window on the mobile, which you must accept in order for the connection to be established correctly with that PC. Let’s take a closer look at him.
Enable developer options
USB troubleshooting is found in the developer options, a menu hidden in the system settings. Therefore, to enable USB debugging, you must first make the Scheduler menu visible as follows:
- Access Android system settings.
- Tap ‘About phone’ or ‘About tablet’
- On the next screen, tap «Build number» seven times in a row.
- At the end of this touch sequence, a message should appear indicating «You are now a programmer». The «Developer Options» menu should already be visible in the main Settings or Configuration menu of the Android system.
Enable USB debugging
As I said, after doing the above, the «Developer Options» or «Developer Options» menu should already appear in System Settings. So do the following:
- Go to settings and tap «Developer options.»
- Just switch the «USB Troubleshooting» switch to turn it on.
- When you connect your device to the computer with the USB cable, you need to «Allow USB troubleshooting», as shown in the image above. In other words, in the application window, click «Accept».
Note: On some devices, when you enter «Programmer Options», you may see its options inactive, disabled, or grayed out, including the «USB Troubleshooting» option mentioned. This is because this screen with developer options is disabled. You simply need to activate it from the switch that is usually at the top of this screen.
Disable USB debugging
At first I explained that USB debugging allows you to do advanced things, and you’ll probably want to leave it turned on if your cell phone screen breaks. This way, you’ll be able to connect it to your computer and manage it using several applications available for this task.
However, USB debugging also allows you to install an APK on your computer without having to touch your phone. The downside is that you will leave a «door open» and with it the possibility of a virus entering your Android device. This is perfectly possible and in fact there are viruses that are passed from the computer to the mobile phone simply after connecting via USB.
From the above, you may want to keep USB debugging off and only enable it when needed. And based on the same, Avoid connecting your mobile phone to any public computer. Obviously, turning off USB debugging is as simple as turning off the same switch used to turn it on. You don’t have to turn off developer options, just the debugging option.
