Part 1. Notes for Enabling USB Debugging on Android

People usually need to switch on USB debugging when flashing firmware, transferring files through ADB, running diagnostic tools, or troubleshooting a misbehaving app. If your phone still turns on normally and you can navigate its menus, you can simply follow the Settings-based steps in Part 2. But if the screen is locked, cracked, or unreachable, you'll need to enable the feature from a computer instead, which is covered later in Part 3.

Part 3. How to Enable USB Debugging on Android from Computer

If your phone is locked, stuck in recovery mode, or showing a black screen, enabling USB debugging through Settings may not be possible. In these cases, you can attempt to activate USB debugging remotely from a PC using either ADB commands or a USB OTG adapter paired with a mouse.

01Enable USB Debugging on Android Using ADB Commands

This approach only works if USB debugging was already switched on before the phone got locked and your computer was previously trusted by the device. If neither condition is met, ADB generally can't reach a locked screen.

Step 1. Get the Android SDK Platform Tools package and set it up on your computer.

Step 2. Use a USB cable to establish a connection between your Android device and the PC.

Step 3. Open a command prompt or terminal window and run adb devices to confirm the phone is detected.

Step 4. If recognized, run adb shell settings put global development_settings_enabled 1 followed by adb shell settings put secure usb_debugging_enabled 1.

Step 5. Check your phone's Developer options menu to confirm USB debugging is now active.

02Enable USB Debugging on Android Using USB OTG

This method is handy when the touchscreen is cracked or unresponsive but the display itself still shows an image. Pairing a USB OTG adapter with a mouse lets you click through menus as if you were tapping the screen.

Step 1. Get a USB OTG adapter compatible with your phone's charging port.

Step 2. Plug a standard USB mouse into the OTG adapter, then connect the adapter to your phone.

Step 3. Use the mouse cursor on your screen to open Settings and navigate to About phone.

Step 4. Click Build number repeatedly to unlock Developer options.

Step 5. Open Developer options and click the USB debugging toggle to switch it on.
