I have tried 3 different chargers and my nexus will only charge when the charger is forcibly pushed into the port, which is not possible to do for a long time, what can i do to fix the problem as at the moment my nexus has been rendered useless. 
Also if i cannot fix the micro usb port does the new nexus 7 dock need the use of the micro usb port or do the pogo pins charge the device on their own
Thanks in advance
