My one year old Samsung Galaxy a20 is showing up a notification which reads that " USB connector connected/disconnected " even if I didn't connect any usb device . I even got replaced the USB port at the service center but the problem still persists plz help me 

The phone is finding very difficult to turn off

Look it's showing a notification of usb connector

do one more thing
go to settings >developer option> search for default usb configuration >click on it> and set as charging only and lets see

and if you not yet enable developer option then follow these steps

Steps to enable developer option
settings >about phone>software information >then u find build number >tap 7 times>then back to settings
and at end of settings one new option called developer option
click on it and find that option

and if after all these not work then send feedback to Samsung by using get help section
