ADB Stops Detecting My Phone After a While: Troubleshooting Guide
Experiencing issues with ADB intermittently recognizing your phone can be frustrating. This guide aims to help you diagnose and fix the common culprits behind this problem.
Common Causes and Solutions
1. USB Debugging Enabled?
ADB relies on USB debugging mode to communicate with your device. Ensure it’s enabled:
- Go to **Settings > About phone**.
- Tap **Build number** 7 times to enable Developer options.
- Return to **Settings > System > Advanced > Developer options**.
- Enable **USB debugging**.
2. USB Connection: Check and Reconnect
- Try a different USB cable, ensuring it’s high quality and specifically designed for data transfer.
- Connect your phone directly to your computer’s USB port, bypassing any hubs or extensions.
- Check for any physical damage to the USB port on your phone or computer.
- Disconnect and reconnect your phone. This often helps re-establish the connection.
3. USB Drivers: Update or Reinstall
Outdated or corrupt drivers can prevent proper communication. Update or reinstall your device’s USB drivers:
- **Windows:**
- Open **Device Manager** (search for it in the Windows search bar).
- Expand **Portable Devices** or **Other Devices** to locate your phone.
- Right-click on your phone’s entry and select **Update driver**.
- Choose **Search automatically for updated driver software**.
- **Mac:**
- The latest macOS versions typically install necessary drivers automatically. If not, visit your phone manufacturer’s website for drivers.
4. Power Management Settings: Disable
Windows’ power management features might interrupt USB connections to save power. Disable these settings:
- Open **Device Manager**.
- Expand **Universal Serial Bus controllers**.
- Right-click on your phone’s USB entry and select **Properties**.
- Go to the **Power Management** tab.
- Uncheck the box for “Allow the computer to turn off this device to save power.”
5. Restart: Refreshing the Connection
- Restart your phone and computer. This can often fix temporary software glitches.
6. Check for System Updates
- Install any pending updates on your phone and computer. Software updates can address compatibility issues.
7. ADB Server Issues: Restart
Restart the ADB server if it’s causing connection problems:
adb kill-server adb start-server
8. Phone’s Storage: Clear Cache
- Clearing the cache on your phone can resolve connection issues caused by corrupted files. Go to **Settings > Apps & notifications > See all apps**, find the “ADB” app, and clear its cache.
9. Antivirus Software: Temporarily Disable
If your antivirus software is interfering, temporarily disable it to see if it resolves the issue.
10. Hardware Fault: Check for Damage
- Inspect the USB port on your phone and computer for any signs of damage.
- If you suspect a hardware issue, consult your phone manufacturer or a qualified repair center.
