Charger is still fine and phone is 3 months old. Phone charging/usb port is burnt (i donno how) i just left it charging in night. When i went to service centre they said that it was due to short circuit and thus does not covers under warranty. They also said that i have to change the motherboard which costs a lot. But the phone is working fine only problem is that it is not charging. Please provide some solution. I am sure that motherboard is fine as the phone is functioning properly.
