I have using same issue last 15 day's, i cant make off the lock screen & connectordisconnected shows always on notification panel, I'm done all possible methods like, reset setting, try in safe mode, update to latest software, clean port by soft brush with hair dryer, etc.
But mine is fixed for temporary.
1) I tried drain the battery to 10 percent and switching off the mobile and connect the charger and charged for 100%. Remove the charger and after 30 minutes restart the phone. It's worked seriously. After that I'm doing just like that. They giving fast charging too in phone after switched off.
