Sign [Q] With IceCreamSandwich, constantly having apps uninstalled?!?!

I have a Samsung Blaze, stock IceCreamSandwich OS.

I keep running out of internal storage and apps keep getting deleted. I've read that the OS hogs a lot, not surprising. I mainly use camera and text/multimedia messaging. Is there a way to change the default storage location for those to go to my SD card?

My apps keep getting uninstalled (greyed out or Android generic icon) so this is very aggravating.

Thanks in advance!
