I own a samsung phone running android L. Having apps that occupy bigger space like Facebook, I have atleast 1.8 GB remaining internal memory. So i bought a 4gb SD card to transfer this app so i can free some memory. The transference was successful however I checked the phone memory but it's still the same. Nothing happened. How is it possible ? I dont really understand the process of transferring an app to SD Card tbh. Did i just waste my money for the SD card?
