Hello, I'm using a Samsung Galaxy Note 2 and it was working just fine till before I updated it with the latest "Software Update" the device had recognized two days ago. Now the device got successfully updated, but when I tried charging my phone yesterday, it didn't charge. In fact, using any wall charger it does not charge. It does however get frozen on the current screen as soon as you put the micro USB in the slot regardless of if the other end is connected or not. And it goes back to the normal state when taken out. Also, the device is charging normally through the computer but the PC is not recognizing the device. In fact, even the "Connected as Media Device" option doesn't come. Also, sometimes that message keeps popping up on connecting (doesn't charge but) - "Connected to dock". What could be the issue?
