Are you tired of dealing with the frustration of your Samsung phone constantly saying “USB connected” then “disconnected”? You’re not alone. This issue is a common problem that many Samsung users face, and it can be caused by a variety of factors. In this article, we’ll explore the possible reasons behind this issue and provide you with some troubleshooting steps to help you resolve it.
Understanding the USB Connection Process
Before we dive into the possible causes of the “USB connected” then “disconnected” issue, let’s take a brief look at how the USB connection process works. When you connect your Samsung phone to a computer or other device using a USB cable, the phone’s operating system recognizes the connection and establishes a communication link with the device. This link allows you to transfer data, charge your phone, and use other USB-related features.
However, sometimes the connection can be interrupted, causing the phone to display the “USB connected” then “disconnected” message. This can be frustrating, especially if you’re trying to transfer important files or charge your phone.

So, what causes the “USB connected” then “disconnected” issue on Samsung phones? Here are some possible reasons:
Loose or Damaged USB Cable
A loose or damaged USB cable can cause the connection to be interrupted, leading to the “USB connected” then “disconnected” message. Try using a different USB cable to see if the issue persists. If you’re using a third-party cable, try switching to a genuine Samsung cable.
