We will start with the basic solutions and move to the advance fixes below.

1. Restart your device

The first step that you need to take is to restart your device simply. Restarting the device will remove any temporary bugs or issues causing the device’s USB connector to show a disconnected/connected notification.

If restarting the device once doesn’t solve the issues, you can try restarting it 4–5 times in a row. 

Some users have fixed the issues by just restarting their smartphones multiple times. It might work for you as well.

2. Clean the USB port

The USB port of your phone can become dirty or clogged with debris, which can cause issues with connectivity and error, such as what we are discussing today.

The fix has already worked for many people, and Samsung support also recommends this solution to fix the ‘USB Connector Disconnected Notification.’

With that said, follow the steps to clean the USB port on your device.

Note: Power off your device before proceeding with the steps below:

  • Use a toothpick or small brush to remove debris

To avoid damaging the USB port on your Android device, use a toothpick or a small, soft-bristled brush to gently remove any debris or dirt from inside the port.

  • Blow out debris with compressed air or hair dryer

To remove any remaining debris or dirt from the USB port, use a can of compressed air to blow it out. If you don’t have a can of compressed air, you can also use a hair dryer on its cool setting to blow out the debris.

  • Clean the port with rubbing alcohol and cotton swab

If the USB port on your Android device is still dirty, you can use a cotton swab lightly moistened with rubbing alcohol to clean it.

Be careful not to get any liquid inside the port and wait for a few minutes before plugging in your USB cable to allow the remaining alcohol or moisture to evaporate.

Below are the comments of some users, who have fixed the USB connector connected/disconnected notification by cleaning the USB port:

Nice one just sorted my phone out there was a little bit of dust. Sorted it right out. Cheers!

This procedure solved the problem for my M52. I cleaned the usb C port with a small plastic toothpick whith the phone switched off. When I switched on again the problem was gone. Thanks for the hint.

8. Update your device software

Updating your device software can help fix many issues, including the USB connector disconnected notification on Android devices.

So, if your device is not updated to the latest version, you could have issues with the USB connector.

Here’s how to update your device software:

  1. Go to “Settings”.
  2. Scroll down and tap on “System” or “Software Update.”
  3. Tap on “Download and Install” or “Check for Updates.”
  4. If an update is available, tap on “Download” and wait for the update to complete.
  5. After the update has downloaded, tap on “Install” to begin the installation process.

Your device will restart, and the installation process will begin.

Once the installation is complete, your device will restart again, and you’ll have the latest software version.

9. Changing USB Mode Settings

If you are experiencing issues with your Samsung device’s USB connection, you may want to try changing the USB mode settings.

Here’s how you can do it:

  1. Open the phone app on your Samsung device and dial *#0808#.
  2. As soon as you press the last ‘#’, the USB Settings menu will appear with several options.
  3. Select the last option “RMNET+DM+MODEM+ADPL” and press “Apply”.
  4. Exit the menu and confirm that the setting has been applied.
  5. Press “Apply” again and then press the “REBOOT” button to restart your device.

Once your device restarts, check if the USB connection issue has been resolved. This method has been reported to work for some Samsung users.

If the issue persists, you may want to try other troubleshooting steps.

10. Boot in Safe Mode

Once your device boots in Safe Mode, all third-party apps and services will be disabled, allowing you to determine if the USB connection issue is caused by a third-party app or not.

If the issue is not present in Safe Mode, then it is likely that a third-party app is causing the problem. You can then try uninstalling any recently installed apps to see if the issue is resolved.

Follow the steps to boot your phone in safe mode: 

  1. Power off the phone or tablet completely.
  2. Power on the device and wait for the Samsung logo to appear.
  3. Press and hold the Volume down key.
  4. If done correctly, “Safe mode” will display on the bottom left corner of the screen. If “Safe mode” does not appear, repeat the steps above.
  5. Once in Safe mode, locate and remove the third-party app causing issues.
  6. To exit Safe mode, simply restart your phone or tablet, and it will reboot normally.

11. Connect to a PC or Laptop

Another solution is to attach the smartphone to a PC or laptop’s USB port, which will start charging the smartphone and may remove the “USB connector connected/disconnected” notifications.

12. Factory Reset

Performing a factory reset on a Samsung smartphone can help resolve software-related issues and return the device to its original state.

Note: Factory resetting your smartphone will erase all data and settings on the device (including photos, videos, account, contact, apps, etc), so it’s important to back up any important data before proceeding with the reset.

Here are the steps to perform a factory reset on a Samsung smartphone:

  • Go to the “Settings” app on your smartphone.
  • Scroll down and select “General management.”
  • Tap “Reset.”
  • Select “Factory data reset.”
  • Review the information on the screen, then tap “Reset.”
  • If prompted, enter your device’s password or PIN.
  • Tap “Delete all” to confirm.

Wait for the reset process to complete, which may take a few minutes. Once the reset is complete, follow the on-screen instructions to set up your device as new.

13. Try a new charging cable/Original charger

If you’re experiencing issues with your phone continuously displaying the USB connected/disconnected notification, it could be due to a faulty or damaged charging cable.

Sometimes, a damaged cable can cause your phone to detect a connection issue and trigger the notification repeatedly.

To fix this issue, try using a new charging cable and see if the problem persists. If the issue goes away, then the problem is likely due to a faulty cable.

Also, make sure to buy or use a cable that’s compatible with your phone and has the proper specifications for charging.

For example: I faced the same issue on my Samsung device, where constant “USB connector connected/disconnected” notifications kept my screen awake. The problem arose when I used a high-power charger, causing the notifications to persist even after disconnecting. Switching back to my original charger solved the problem.

14. Try getting a cheap battery backup case

If you’re experiencing USB connected/disconnected notifications and your phone keeps lighting up, you might consider getting a cheap battery backup case to solve the problem.

By using a battery case, your phone will always be plugged in, and therefore the notifications should stop.

This is recommended by a user,  who got a cheap $10 Mophie case off Amazon, which has worked well for him for about 3 weeks.

Although it may not solve the issue completely, using a battery case can be a viable solution as it can help your phone work as it should and provide extra battery life.

15. Disable USB Connected Notification

While putting the USB connected notification on silent and activating minimize notification may hide the notification, it doesn’t completely solve the issue.

Note: The notification still continues to pop up in the notification history, and the constant turning on of the screen can drain the battery to some extent.

Final Words:

So, that’s all for now folks. I hope after reading this post, you were able to fix the USB connector disconnected notification keeps popping up error.

If you are still experencing the issues, you can try contacting Samsung support or visit a nearby service center.
