Smartphones often interface with USB devices. Additionally, the smartphone ports and software get better; this communication will only increase in frequency. That said, USB connections don’t always go as planned when discussing smartphones. 

In this article, we’re talking about the USB connector disconnected error notification on Android, its causes and what you can do to fix the error. 

What causes this error?

The error often shows up when no USB device is connected and can be caused by several reasons. Some of the most common reasons are as follows:

  • Mechanical damage to the phone’s USB port.
  • Dirt or debris causing improper contact. 
  • Faulty USB charging or data transfer cable.

How to fix this?

Here are four fixes you can try out. 

Inspect your charging port

The first thing you should do is check to see if the USB charging port on your phone is free of any dust, debris or damage. Broken, bent, or corroded pins inside the charging port can cause the phone to think a USB device is connected.
