A:AnswerYes this can be used with a smartphone. I use an iPhone and the compatible app is called MiniPrint from Canon which can be downloaded from the App Store.
A:AnswerI don't have a note myself, but I do know it won't work with older Iphones. The printer uses an app in order to print your pictures, so you could check if it's compatible with your phone's software by going to the app store and trying to download it. Just search "cannon mini printer" and the app should pop right up. As long as the app works on your phone, the printer will work! Hope this helps.
