I have a Galaxy Grand Prime sm-g530t with a Kingston 8GB microSD memory card. I would like to add more apps, but there is not a lot of room in phone's memory after T-Mobil put all their junk apps on it that cannot be deleted. How do I move or download apps to the SD memory card? I found in setting under applications, application manager that there is an option to move apps to the SD card but almost every application, IE. Steam, Hulu, Spotify etc. the button is inactive. Only a few apps allowed this. Is there another way to move apps to the SD card? Or alternatively is there a way to safely delete the junk apps from T-Mobil?
