Hi I am using a samsung s4 it's really old mind and a lot of apps don't work with it but the app used to create the amiibo works fine. So perhaps go for that kind of brand?
Thanks! I only just said to someone else on another post about looking at getting a phone today! at least with a model type i might be able to get hold of a second hand one! do you think the active ones work the same way? I have read they support nfc and if it's hard wearing then i wont be scared to drop it lol.
