Check Your USB Cable

One of the most common culprits behind the “Samsung A51 USB connected disconnected” issue is a faulty or subpar USB cable. A low-quality cable can lead to unreliable connections, frustrating interruptions, and data transfer problems.

Visual Inspection

Start by examining the USB cable for any visible damage. Look for frayed wires, bent connectors, or any physical defects. If you spot any issues, it’s a clear sign that the cable needs replacement. Even minor damage can disrupt the connection.

Try a Different Cable

To rule out the cable as the problem, swap it out with a different USB cable that you know is functioning correctly. If your device connects reliably with the new cable, you’ve found the source of the issue.

Check Compatibility

Ensure that the USB cable you’re using is compatible with your Samsung A51. Not all USB cables are created equal, and using one that isn’t designed for your device can lead to connection problems.
