It looks like your laptop is not detecting your mobile device via ADB (Android Debug Bridge). Here are some troubleshooting steps to resolve this issue:
1. Check USB Connection
- Use a different USB cable (preferably an original or high-quality data cable).
- Try connecting to a different USB port on your laptop.
- Avoid using USB hubs; connect directly to your laptop’s port.
2. Enable USB Debugging on Your Phone
- On your phone, go to Settings > About Phone.
- Tap Build Number 7 times to enable Developer Options.
- Go to Settings > Developer Options and enable USB Debugging.
- Set USB Configuration to File Transfer (MTP) or PTP instead of Charging Only.
3. Verify ADB is Installed Properly
- Open Command Prompt and type:
sh
CopyEdit
adb version
If ADB is not recognized, reinstall ADB drivers or platform-tools.
4. Restart ADB Server
- Run the following commands in Command Prompt:
sh
CopyEdit
adb kill-server
adb start-server
adb devices
5. Check for Unauthorized Device
- When connecting your phone, check for a pop-up on your phone asking to authorize USB Debugging.
- Tap “Allow” or “Always allow from this computer.”
6. Install or Update USB Drivers
- If using Windows, update or reinstall your phone’s USB drivers:
- Download OEM USB drivers from your phone manufacturer’s website.
- Install Google’s USB driver (for Nexus/Pixel devices).
- If using Samsung, install Samsung USB Drivers.
- If using Mac/Linux, install ADB via Homebrew (
brew install android-platform-tools) or package manager.
7. Check Device in Device Manager (Windows)
- Open Device Manager (
devmgmt.msc). - Look under “Android Device” or “Portable Devices”.
- If you see “Unknown Device” or a yellow warning sign, right-click and update/install the driver.
8. Try a Different Laptop or OS
- If possible, check if the phone is detected on another computer.
- Try using Linux or Mac to see if ADB works there.
