USING TITANIUM BACKUP
The most advanced way to control your apps and data is to use Titanium Backup, though it'll cost you RM22.46 to enable all its powers. This is the app that many hardcore users turn to when they want to backup/restore their apps, or remove, disable, or “freeze” them. This is a very powerful app that can be dangerous if not used correctly.
Also, to use Titanium Backup, you need a rooted device. In a nutshell, this means giving yourself and the app you've chosen unrestricted access to the system files. For the most part, we don't recommend rooting your Note5 or S6 edge+. It will trip Knox (a built-in Samsung security feature) and disqualify your device from using security-focused features, like Samsung Pay. It also voids your warranty.
If you like to live dangerously, check out these two forum threads on XDA Developers (gohwz.ws/1NoPm0f and gohwz.ws/1NoPpJs) to find out more about rooting your new Galaxy devices.
For backing up, disabling, and restoring apps, Titanium Backup is the gold standard. But it needs a rooted device.
