Okay so out of nowhere, my Galaxy Nexus won't charge. While powered off it shows that it is charging but when I actually power it on, it almost immediately powers off from lack of battery power. It's as if it hadn't charged at all when it was powered off. I have tried 3 different chargers and it's always the same result. Also sometimes when I power it on, the whole home screen is rotated sideways. I am running AOKP. Any ideas? Thanks.
