My wife has the Samsung Galaxy J3 2016, I had to delete her fitbit App because she was having problems, I have gone into Google Play Store to reload the app onto her phone but it wont download it says already installed, when it isnt, any help muchly appreciated.
Go into your playstore app and press the 3 lines icon in the search bar and press the My Apps and Games option and look at your library as the app on question may still be there.
Also look in settings and Apps to see if the app is still there even though you've gone through the uninstall sequence @Tankie1rtr

The advice I offer is my own and does not represent Samsung’s position.
