If you want to control operations in your own app, nAN-36 and the code here should be a good starting point. 
 If you want to control the OS on the phone, or generic apps, you'd probably have to make a HID over GATT device, and rely on the HID support of the phone OS. HoG is a pretty complicated service, but there are a couple of examples in the nRF51 SDK that should be useful starting points.
