Does your Samsung Galaxy phone keep showing the “USB connector connected” and “USB connector disconnected” notifications? These alerts can be extremely frustrating, as they keep your screen awake and drain the battery of your phone. There can be several reasons for this, ranging from incorrect settings to a faulty USB port or cable. This guide includes all the possible solutions that will help get rid of USB connector connected or disconnected notifications on your Samsung Galaxy phone.
1. Clean the Charging Port and Check the USB Cable for Damage
A common reason why your Samsung Galaxy phone may repeatedly show the “USB connector connected” and “USB connector disconnected” notifications is if there’s a problem with the charging port. Hence, the first thing you should do is clean the charging port using a cotton swab and remove any dust, lint, or other particles.
If you only encounter these alerts while charging your Samsung Galaxy phone, consider using a different USB cable. This will help you determine whether a damaged charging cable is triggering the USB connector connected or disconnected notifications on your Samsung Galaxy phone. Likewise, if you observe these warnings while using an OTG cable or adapter, it may be damaged or faulty.
2. Clear USB Cache and Data
Corrupt or outdated USB cache data on your Samsung Galaxy phone can also give rise to such alerts. Several users on a Samsung community post reported fixing the issue almost instantly by clearing the USB data. You can also give it a go.
1. Open the Settings app on your phone and navigate to Apps.
2. Tap the Filter and sort icon and enable the Show system apps toggle. Then, tap OK.
3. Scroll down to tap on USBSettings.
4. Go to Storage and tap the Clear cache option in the bottom right corner. Then, tap the Clear data option.
3. Enable USB Debugging and Modify the Default USB Configuration
At times, your Samsung Galaxy phone might misinterpret the connected charger as a USB flash drive or computer, resulting in repeated Android System notifications. To fix this, you will need to enable USB debugging and change the default USB configuration on your phone.
1. Open the Settings app and scroll down to tap on About phone.
2. Go to Software information and tap the Build number seven times to activate the Developer options menu.
3. Return to the Settings menu and tap on Developer options. Then, enable the toggle next to USB debugging.
4. Scroll down to tap on Default USB configuration and select the Charging phone only option.
4. Turn On Your Phone With the Charger Plugged In
Another thing you can do to make the “USB connector connected” and “USB connector disconnected” alerts go away is to unplug the charger, power off your Samsung Galaxy phone, and then reconnect the charger. Once your phone begins charging, try turning it on and check if the Android System alert persists.
5. Force Stop Android System
Android System is an important app that manages some of the core features and services on your phone. If there’s an issue with it, your Samsung Galaxy phone could misbehave and show USB connector connected or disconnected notifications.
You can try force-stopping the Android System app to see if that restores normalcy.
1. Open the Settings app on your phone and navigate to Apps.
2. Tap the Filter and sort icon and enable the Show system apps option. Then, tap OK.
3. Scroll down to tap Android System.
4. Tap the Force stop option in the bottom right corner and hit OK to confirm.
6. Inspect the Charging Port for Water Damage
There’s a chance that the presence of moisture within the charging port on your Samsung Galaxy phone is causing it to display USB alerts and keep the screen awake. If that’s the case, you must power off your phone and gently shake it to remove any excess moisture from the charging port.
After that, restart your phone and check if the alert still appears.
7. Reset Your Phone
If all else fails, you can consider resetting your phone. This will restore all custom settings to their default values, without affecting your apps and personal data.
1. Open the Settings app and tap on General management.
2. Scroll down to tap Reset and select Reset all settings from the following menu.
3. Tap on Reset settings and enter your device PIN or password to proceed.
USB Alerts, Be Gone
It can be frustrating when your Samsung Galaxy phone keeps showing notifications about the USB connector connected or disconnected and keeps the screen from turning off. Hopefully, one or more of the above tips has helped to stop the “USB connector connected” and “USB connector disconnected” notifications on your Samsung Galaxy phone and restore normalcy.
