The chargers will not go in. I think the charging port needs repair. How can this be done on LG Optimus L90
Is the port bent? Are one of the prongs inside the port popped up? If either one of those is a yes. then you need to replace the port on the actual phone. If none of those is thne problem. Try getting a new charger and see if that works. Or try putting it in on an angle. Goodluck! -JR
