I too have used HC-05 and my HTC One M8 (Android) phone to connect and control many BT things I have built (mainly RGB lighting and simple on/off switching)
I too use Bluetooh Terminal app... I have also used S2 Terminal for Bluetooth app..
My projects are set up to take some serial data.. so using these apps I can tailor my serial data to meet my sketches needs.
As Runaway Pancake mentions... throw some AT commands at it.. change the name.. and then try again.
