I am a big fan of the Nex cameras and have recently got the nex 6 thinking I can take industrial photos from the top of a pole and activate the shutter from my Galaxy Note 2. Anyway you know the rest of the story. If you fix your software I think your sales will go up due to the Note being the most practical android partner for the Nex in this scenario (based on screen size and clarity).
Currently our engineers are aware pictures will not wirelessly transfer to the Galaxy Note 2.
What we have noticed, is Play memories Mobile will see the camera, say its connected but then after a few seconds a disconnected error occurs. All we can suggest at this time is to make sure you are running Android 4.1.1, Once we have more information it will be posted.
