I have a LG K7 and it hasn't even been a month. My battery wasn't charging instead it was dying. When it died I tried charging it but it wouldnt charge. I thought maybe it was the USB cable cord but as soon as I connect it to my tablet it worked fine. I took out the battery put it back in and still no charging. I checked the port inside the phone and it's not broken also it's clean. I tried different chargers and wall outlet and it is still not working. Is there a solution to my problem?
