Install It If You're Using Up Tons of Data
If you find yourself chewing through your data plan, consider downloading the Android Nougat update soon after it arrives for your Galaxy S6 model.
Android 7.0 Nougat features Data Saver, a feature that can help you do exactly that when it's turned on via your Settings.
Nougat's Data Saver function allows you to cut data usage off from apps that don't necessarily need to be eating up data in the background.
It also cuts down on the data usage of apps that are currently in use. For example, some images might not be shown until you tap on them.
The feature gives you some control over what apps get access to unrestricted data. This way you can make sure your most important applications are whitelisted.
