If the apps don't show up on your homepage or your apps page they are probably pre installed factory apps and incompatible for your device!
Tell ya how to find out.
Go to play store, menu, my apps and games,then all apps. If you find the apps there tap on them. Then it might say -incompatible for your device -. If it does that means when your device was originally programed they installed a standard package of apps! And it's a good bet that some of these apps are for older model phones and they won't work in your phone anyway!
Un fortunately the only way to get rid of them is to reroot your device.
Hope that answers your question
Thank you, Lindsay.
An example of these special apps for my phone is 'Google Play services'.
