I have purchased a 2 device and a 3 device licence. Unfortunately the 3 device appears to be PC only whereas the 2 also works on Android. What I have done is use one of the 2 device on my laptop and now unable to protect S5 and tablet. So what I need to do is swap the one on laptop to S5 and use one of the other (one of the 3 Device) onto laptop. Hope this makes sense. Cheers
