How To Fix Samsung Galaxy S7 wifi Connectivity Issue

Connecting your Samsung Galaxy S7 to a computer is a convenient way to backup and transfer files. However, it can be frustrating when your phone is not detected or recognized by your PC. In this troubleshooting guide, we will address two common issues related to this problem: when the phone cannot be detected by the computer and when it is detected but not recognized. We will provide step-by-step solutions to help you resolve these issues and establish a successful connection between your Galaxy S7 and your computer.

Troubleshooting a Galaxy S7 That’s Not Detected by Your Computer

If your Galaxy S7 is not being detected by your computer when connected using the USB cable, there are a few troubleshooting steps you can try before assuming it’s a hardware issue.

Step 1: Connect your phone to other USB ports on your computer

Start by connecting your phone to different USB ports on your computer. Sometimes, the issue may be specific to a particular USB port. By trying different ports, you can rule out any problems with the USB port itself.

Step 2: Reboot your PC if all USB ports didn’t work

If your phone is still not being detected after trying different USB ports, it’s worth rebooting your computer. This can help resolve any system issues that may be preventing the detection of devices. After rebooting, reconnect your phone and check if it gets detected.

Step 3: Verify the USB cable doesn’t have a break or something

Inspect the USB cable for any visible breaks or damage. If you find any, it’s likely that the cable is causing the issue. Additionally, try charging your phone using the cable to see if it charges properly. If the cable is faulty, replace it with a new one that you know works.

Step 4: Make sure the USB option is set as “media device”

On your Galaxy S7, check if the USB option is set to “media device” mode. This mode enables data transfer between your phone and the computer. To check this, pull down your notification bar and look for the USB options icon. If it’s there, simply tap on it and select “Media Device (MTP).” If the USB options icon is not visible, try the following:

  1. Unplug the USB cable from your Galaxy S7.
  2. Power off your phone.
  3. Wait for 20 seconds.
  4. Power it back on.
  5. Plug the USB cable back into your phone.
  6. Check if the USB options icon appears.

If the USB options icon is still not visible, proceed to the next step.

Step 5: Check the charging port on your phone

To rule out any issues with the charging port on your phone, try using different cables. If your phone is still not detected by the computer, inspect the charging port for any debris, lint, or dirt. Use compressed air to clean out any foreign particles. Check if the connection between the cable and the port is secure. If the problem persists, there may be a more serious hardware issue that requires professional assistance.

Step 6: Let the tech check and/or repair your phone

If you have followed all the troubleshooting steps above and your phone is still not detected by your computer, it’s recommended to seek professional help. A technician can diagnose and repair any hardware issues without voiding your device’s warranty. Reach out to the manufacturer or an authorized service center for further assistance.

Troubleshooting a Galaxy S7 That Can’t Be Recognized by Your PC

If your Galaxy S7 is detected by your computer but not recognized, preventing file transfers, follow these troubleshooting steps to resolve the issue.

Step 1: Unplug the cable from your phone and reboot it and your computer

Start by disconnecting the USB cable from your phone. Then, reboot both your phone and your computer. This can help eliminate any temporary glitches or conflicts that may be causing the recognition issue. After the reboot, reconnect your phone to see if it gets recognized.

Step 2: Make sure necessary drivers are installed on your computer

Check if your computer has the necessary drivers installed to recognize your Galaxy S7. While recent operating systems install generic drivers for most USB devices, smartphone manufacturers like Samsung provide their own drivers or software suites for seamless recognition. Visit the official Samsung website and download the software suite specific to your device, such as KIES or Smart Switch.

Step 3: Reset your phone if the problem persists after installing KIES or Smart Switch

If the issue persists even after installing the necessary software suite, you can try resetting your phone to resolve any software conflicts. However, please note that this step will erase all data on your phone, so ensure that you have a backup before proceeding. To reset your Galaxy S7:

  1. Turn off your Samsung Galaxy S7.
  2. Press and hold the Home and Volume Up keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 logo appears, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo appears, release both keys and wait for 30 to 60 seconds.
  5. Use the Volume Down key to navigate and highlight ‘wipe data / factory reset.’
  6. Press the Power key to select the option.
  7. Highlight ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  8. Wait for the Master Reset to complete. Once finished, highlight ‘Reboot system now’ and press the Power key.
  9. Your phone will reboot, and you can then reconnect it to your computer to check if the recognition issue has been resolved.

If the problem persists even after a reset, it’s recommended to seek professional assistance to further diagnose and resolve the issue.


Connecting your Samsung Galaxy S7 to your computer should be a simple process, but issues can arise that prevent detection or recognition. By following the troubleshooting steps outlined in this guide, you can resolve these issues and establish a successful connection. Remember to try different USB ports, check the USB cable and charging port, ensure the USB option is set correctly, and install the necessary drivers. If all else fails, seek professional assistance for further diagnosis and repair.
