I have only had my hero for 5 months and it all of the sudden decided to act up. The battery symbol in the notification bar is grayed out and has an exclamation point in it. The notification LED is flashing from amber to green to amber constantly. When it is doing this my phone wont take a charge. It occasionally lightens up a bit and takes a charge but then spirals downward more so than less. I've taken the battery out and left it out for a long period of time just to put it back in and have it do the same thing. I have taken it into 3 stores and no one knows what it means. They gave me a new battery and charger and still no luck. Anybody have an idea what is going on? Thanks!
