Is anyone else's connection via the USB very loose when connecting to a PC of some kind? Mine has a tendency to connect and disconnect over and over because it seems the connection is very sensitive. Not a fan of that at all. I remember transferring some files and accidentally nudged the Note 2 and it disconnected, therefore cancelling the transfer. This is my 2nd Note 2 with a different USB connector and it still does the same as my first one.
