Hi,
Bought my 520 from overseas and it appears the micro usb has broken after 8 months of usage. I have tried many different cables and none charge. If I forced the cable to one side the computer would recognise it. However I think doing this has dislodged the usb port as it now comes out a bit.
I recognise that I probably have now broken it but this would not have happened if it was working in the first place. Has anyone else had problems like this? It seems pretty poor quality to stop working after 8 months.
