Why does my phone say it's connected via USB when it isn't?

Samsung Galaxy S7 Edge

Mike's Galaxy S7 Edge keeps pinging that it's connected to a USB even when it isn't. Leo says that could be a ghost issue. He should turn off USB debugging in the developer settings. He needs to go to into Settings > About Phone, and tap the build number 10 times. Then he'll get into the developer's menu. He should check his phone's USB port for fuzz. He can also try resetting the phone. Then before he reinstalls his apps, he should make sure it isn't happening. If it does still happen, then he does have a hardware problem. If it doesn't, then an app is likely the culprit.
