A:Answer Technically with the iphone...no because of compatibility of software. with the A21, yes but it depends on how you are using the phone. These phones are really meant for light usage (like checking email, text and phone calls...maybe the occasional picture). If the previous mentioned is all you do with it, then you shouldn't have issues with the buds. The only thing I can think of that would cause issues with the app is if you ran out of space for the system apps to run everything and if you are trying to do to much at one time. Hope this helps.
