If I wiggle the cable were it enters the bottom of the phone slightly it starts to charge, but I have to have in a certain position, I've had the phone 2 months, never dropped it or forcibly shoved the charging part into it. Now I have to pay attention to it or it doesn't charge. Anyone run into this, is this normal ? I'm hoping its the cable, don't have another to try it out with, probably gonna buy the lg vortex drop in charger.:-\
