i tried searching the forum but couldn't find one specifically similar to mine.

Everytime I reboot the phone, there will always be a 'Charger Disconnected' signal for about 1-2 seconds. It doesn't charge and there seems to be no signs of defect at the port or the charger... I don't feel any significant lag or battery drain that seems to be bothering but I was just wondering... because I did drop my phone i think like.... 3 times, from probably knee high or slightly higher...

what is the problem?
