[MyPrevail]

samsund galixy prevail getting low memory warning already purchased 32G SD card and moved some of the games and programs that would let me move them. Why cant I move the preloaded programs to SD card? I am also getting automatic updates for programs Im not even using or want to us, like scvngr, layar Poynt and Hookt. Idont like the fact that I was given apps I dont want and wont use and cant get Apps loaded that I do like and want to us because there is no room on my phone.

Some apps just won't let you move them, especially system apps. This is why most people root their phone. Then you can move or even remove whichever apps you want to.

Also, if you go to My apps in the play store, you can go to the apps you don't want to automatically update and uncheck the box that says "Allow automatic updates"
