In this article, we’ll discuss the most common causes of USB connection issues on the Samsung Galaxy S9 and provide troubleshooting tips to help you fix them. We’ll also discuss some additional causes that are specific to the Galaxy S9.

Common Causes

  • Faulty USB cable or USB port. A damaged or dirty USB cable or USB port can prevent your phone from connecting to a computer or other device.
  • Outdated software. Older versions of your phone’s software may not be compatible with the latest USB drivers.
  • Third-party apps. Some third-party apps can interfere with USB connectivity.
  • USB debugging mode enabled. USB debugging mode is a developer setting that can sometimes cause problems with USB connectivity.
  • Hardware problems. A damaged USB port or other hardware problems on your phone can also cause USB connection issues.

In addition to the above, here are some other possible causes of USB connection issues on the Samsung Galaxy S9:

  • Incorrect USB settings. Make sure that your phone’s USB settings are configured correctly.
  • Insufficient storage space. If your phone’s storage space is full, this may prevent you from transferring files over USB.
  • Device compatibility issues. Make sure that your phone is compatible with the computer or other device that you are trying to connect it to.
  • Network problems. If you are trying to connect your phone to a computer over a network, such as a Wi-Fi network, make sure that the network connection is stable.

1. Check the USB cable

Make sure that you are using a genuine Samsung USB cable. Third-party cables may not work properly with your phone. You should also try using a different USB cable to see if that resolves the problem.

To check the USB cable for damage, follow these steps:

  1. Inspect the cable for any visible damage. Look for any cracks, cuts, or fraying.
  2. Check the cable connectors. Make sure that the connectors are clean and free of debris. You can use a can of compressed air to clean the connectors.
  3. Try bending the cable gently. If the cable feels stiff or brittle, it may be damaged.
  4. Try using the cable with a different device. If the cable works with a different device, then the problem is likely with the original device.

2. Check the USB port

Make sure that the USB port on your phone and computer are clean and free of debris. You can try blowing into the ports to remove any dust or lint. You can also try using a different USB port on your computer.


To check the USB port on your Samsung Galaxy S9, follow these steps:

  1. Visually inspect the USB port for any signs of damage, such as cracks or bent pins.
  2. Try inserting a USB cable into the port. If the cable does not insert easily, or if it feels loose when inserted, the port may be damaged.
  3. Try connecting a different USB device to the port. If the other device does not connect, the port may be damaged.
  4. Try cleaning the USB port with a can of compressed air. If the port is dirty, this may be preventing your device from connecting properly.

If you have checked the USB port and it appears to be in good condition, but you are still having problems connecting your device, the problem may be with the USB cable or the device itself. Try using a different USB cable and/or connecting the device to a different USB port on your computer.
