I love your answers, I am not a scientist of gsm and drones. in your zino launch at any time we do not warn future buyers of any problem that we might encounter on android. it's your job before selling it. more when I buy a mobile seller or in the user manual at any time it is stipulated too.Samsungs are renowned for being problematic with various third party apps due to the modification made by Samsung to pure Android even worse if you have purchased a Telco branded model. If as your said you have no problems using your Zino with an iPhone then the issue is your Samsung not the Zino,this is not a Hubsan issue but a Samsung one.
