When charging, phone stays at percentage, doesn't increase or decrease. If i turn my phone off and put the charger in, itll say i have water in my charger port. If i flip the charger bit tht i put into the port then itll charge. If i then turn my phone on once the charge symbol shows, it stops charging. If i plug it into a pc it works fine. What is going on here and how do i get my phone to charge while its on?
