If your device is already root, you can install it directly. If there is no root, you need to go through a very very very complicating operations to enable Ice Box. Please read the full description before making decision. Ice Box is a box to freeze and store the apps you rarely used. Apps in box will be HIDDEN from launcher and won’t be able to steal your battery or cellular data in background. You can easily launch them from Ice Box, just like launch from a home screen folder. They’ll be frozen automatically after screen lock or back to launcher and can’t do anything in background.
