It's a Corelectrics stick, and android Sony Xperia Z android phone. I've managed to pair it but when I try to take a picture it operates the zoom. Likewise if I haven't got the camera app open it increases the volume, not just on the phone but on my PC as well, The volume knob being the zoom knob when IN camera mode. The box suggests installing the camera 360 app (there's loads of camera 360 apps and I've tried the top 3). I've checked the internet, and the Sony Q&A site, and there are similar questions, but no replies. Any ideas?
