I've got some micro USB cords that fit and others that do not. The Note 2 is the first device I've had that was picky about which micro USB cord I used. For example, my Sprint car charger connector that I bought for my old Evo 4G just falls out of the Note 2 when I drive. Some connectors are too big for the Note 2. The Micro USB standard must allow for really wide tolerances.
