I have a Galaxy Core Prime and I seem to have used up all the free space on my phone. I just put in a 16GB card in it, but that didn't seem to make any difference. Out of the few apps I have, only about 5 can be moved to the card. Everything else is grayed out so I can't move them or uninstall them. I'm using Galaxy S Launcher. My phone specs are as follows: Model: SM-S820L Android Version: 4.4.4/KitKat Hardware Version: S820L.05 Internal Storage: 8GB My storage information: System Memory: 2.86GB Device Memory: 4.5GB used/700MB free Used Space: 1.22GB Cached Data: 7.30MB (and that's after clearing the cache) Misc. Files: 3.27GB Available space: 663MB I have 13.50GB space left on a 16GB SD card. Apps currently installed: Flashlight Avast Mobile Security DU Speed Booster Facebook Galaxy S Launcher Google App Google Play Services Goggle Play Store Messenger Zedge Spotify You Tube Anything I can do to make more space?
