Enable “Developer option”

USB Debugging is in the “Developer Options” menu item and it is hidden. You will need to reveal it first:

  • Go to -> “Settings”

  • Go to -> “About Phone”

  • Tap 7 times on “Build Number” - in some cases it can be “Android version". On your third tap, you should see a message indicating that you only have 4 more taps to ‘become a developer’.

Android 2.3

  • Go to -> “Settings”

  • Go to -> “Applications”

  • Go to -> “Development” 

  • Check -> “USB debugging”

Before Android 4.1

  • Go to -> “System Settings”

  • Go to -> “Developer options”

  • Check -> “USB debugging”

  • Un-check -> “Verify apps over USB”

Android 4.2 and higher

  • Go to -> Settings

  • Go to -> “Developer Options”

  • Check -> “USB debugging”.

  • Un-check -> “Verify apps over USB” / ”Install via USB”

For Xiaomi with MIUI, to enable “USB debugging” and “Install via USB”, it will be required to have a SIM card inserted in the phone and also to be logged in to your Mi Account.

If you are running Android 8.0 or later, you must also enable the installation of applications from "Unknown Sources" for the "Forensic Connector" app.

  • Go to -> “Settings”

  • Go to -> “Apps”

  • Select -> “Forensic Connector”

  • Allow -> Install unknown apps

Huawei devices

If you are turning on USB debugging on a Huawei device, make sure to also "allow ADB debugging in charge only mode". This can be found in the Debugging section of Developer Options. This will prevent most of the cases where USB debugging is turning itself off because of EMUI.

For EMUI 5.0 and higher, it might be necessary to connect the phone to the PC prior to enabling USB debugging, because it may otherwise keep turning itself off automatically.
