Nexus 7 says it's charging but it isn't I have had a Nexus 7 since September and today something strange happened.

I plugged it in, as usual, to recharge the battery. It charged up to 36% and now it still says it's charging but it never moves from that percentage.

How can I fix my device?
I solved my issue using a 2A charger instead of my phone 1A charger or the USB port that provides only 0.5A.

I am sure I have been able to charge my nexus with all the power sources, but maybe I left it on charge all night long.
