When you plug in or out the USB cable from your Android phone, the USB connector disconnected or connected notification appears in the status bar. However, some Android users, especially Samsung mobile owners, report that these messages appear continuously. Whether they put the phone on the charger or connect it to the computer, the notification appears in both cases.
The error keeps waking up the phone, resulting in quick battery drainage. If you are facing the same issue but do not know how to fix it, you have come to the right place. In this article, you will find the best ways to counter the Samsung USB Connector Disconnected Connected.
Start with the port and the cable, not a reset. A loose, dirty, or damp USB-C port and a damaged or non-data cable are the most common causes of repeated connected/disconnected notifications. Unplug, check the port and cable, try a different known-good cable and charger, and restart. If you see a water-drop moisture warning, stop charging and dry the port first – that is a different warning from the connected/disconnected notification. Only then move to USBSettings cache, software update, and settings reset, in that order.
Key Takeaways:
- Android’s USB connector notifications issue is common on Samsung devices due to damaged hardware and software glitches.
- You can eliminate it by using the original charger, fixing the port, and trying a different cable and charger.
- To resolve this issue, update the OS, change default USB configurations, clear the USBSettings app cache, restart, or reset the phone’s settings.
8 Fixes for the Samsung USB Connector Disconnected Connected Issue
Though the USB connector issue is more likely to occur on a Samsung phone, it can happen on any Android device. Here are 8 fixes to try on your mobile:
Water-drop icon = moisture protection, charging disabled, dry first. Connected/disconnected notification without a water-drop icon = port/cable/software issue, follow the methods below.
Method 1) Check the Port Condition
The most common reason for this error is the malfunctioning of the USB port, which could have accumulated dirt or been damaged by the water. Even if the phone never comes in direct contact with water, moisture in the air can harm its components.
Power off the phone first. Inspect the USB-C port with a flashlight and wipe the outside with a dry cloth. If lint is visible, remove it only with a non-metallic tool and only if you are confident. Do not insert metal objects and do not use heat. If the port is blocked or damaged, get it cleaned professionally. For a moisture warning, unplug the phone, wipe it dry, shake it gently 5-10 times with the port facing down, dry it in a well-ventilated area or with a fan, and restart only once it is completely dry.
Method 2) Use the Original Charger
Using a phone charger of another brand can also cause issues, such as the USB Connector Disconnected Connected notifications on Samsung. The charger’s output might not be enough for the phone or could have been broken.
Every manufacturer recommends charging the phone using the original charger. You can use the charger in the box or purchase one directly from the device maker.
Method 3) Take Out the USB When Fully Charged
Unplug the phone when it is fully charged and note whether the notification stops. Try a different cable and charger to isolate whether the cable or charger is causing the repeated detection. If the notification stops with a different cable and charger, use that cable and charger.
Method 4) Restart the Mobile Phone
A glitch in the system can also cause the USB connector connected/disconnected notifications to keep popping up. Restarting can resolve such issues and allow the phone processes to run smoothly.
Follow the steps to restart the Android mobile phone:
Step 1) Hold the power button on the right side of the device.
Step 2) Choose the Reboot option.
Wait until the phone reboots completely to check if the notification is gone. Put the device on charge, then disconnect it to ensure everything works properly.
Method 5) Tweak the Settings to Recognize Charging
The issue could arise when your phone does not use the correct default USB configuration.
Follow the Samsung steps below:
Step 1) Go to Settings > About phone > Software information.
Step 2) Tap Build number 7 times, and enter your PIN if asked.
Step 3) Go back to Settings.
Step 4) Open Developer options at the bottom of Settings.
Step 5) Turn on USB debugging.
Step 6) Open Default USB configuration.
Step 7) Select “Charging phone only” or “No data transfer”. USB debugging is a developer tool – turn it off again after testing if you do not need it.
Method 6) Clear the Cache for the USBSettings App
Samsung Galaxy devices collect cache for the USBSettings app, which could become corrupted and result in a USB connector disconnected connected error. Clearing the cache can fix the issue.
Follow the steps to clear the USBSettings cache:
Step 1) Go to Settings > Apps, tap the Filter and sort icon, select Show system apps, tap OK, then tap USBSettings.
Step 2) Tap Storage, then tap Clear cache. Restart the phone after clearing the cache.
Only clear data/storage if clearing the cache alone fails. Clearing data resets USB preferences, not personal files.
Method 7) Check for OS Updates
Android operating system devices often get system updates to address the bug. Failure to download the latest updates on time may result in system malfunctions. Therefore, always check the mobile settings for the newest update or set them to automatic installation. Download and Install only does something when an update is available. Menu names vary by Samsung model, One UI version, and Android 14-16 – use Settings search for “Software update” if the tab name differs.
Here are steps to check for the latest OS Update:
Step 1) Open the settings app and move to the Software update tab.
Step 2) Enable automatic updates and tap on Download and Install.
Step 3) If the update is available, download it.
Restart the device after installing the update for the proper installation, then check if the issue is resolved.

Method 8) Reset Your Phone
Reset all settings should be the last option to fix the USB connector error. Reset all settings resets settings only, not apps or personal data. Do not use a factory reset for this notification issue, as it would erase your data.
Use Reset all settings only, as it can also be effective for the USB Connector Disconnected Connected error.
Here are steps to reset settings on Samsung mobile:
Step 1) Move to the General management in your mobile settings.
Step 2) Open the Reset section.
Step 3) Select Reset All settings and confirm your action by providing your screen passcode.
