There are several way to free up space on Samsung Galaxy S6, you can do the following steps in order to clean your smartphone.
Get an application of cloud storage
The cloud storage is another good way to free up space used by multimedia files. We've already provided a list of the best for Android, and it's something you should consider. In most cases, you can configure these applications to make an automatic backup of the pictures you take, which means that you can delete photos from the storage of your device at any time, and they will remain on your device.
Delete applications you do not use
If you do not want to install another application as recommended above, then you should consider uninstalling some applications. The applications vary in size, in which the most demanding games occupy the most space. If you do not use any application, why is installed? Uninstall applications is a quick and easy way to free storage. You can always reinstall them later if you want.
Use an external SD card
One of the best things about the Samsung Galaxy family devices come with a slot for microSD cards (up to the arrival of the Samsung Galaxy Alpha). An SD card can essentially act as an additional hard drive for your smartphone - you can move images, videos, and even application data instead of storing them in your device. You'll have to buy a microSD card, but you can choose from various sizes in Amazon .
For multimedia files go to Applications> My files and plays on Options (three-dot button at the top right side), then click on them to move the microSD card (if you have one).
Erase application data
Delete application data can save you some valuable megabytes, but has a price. To do anything in an application, Android stored data can be your preferences, habits, anything you've done since you installed the.
Think of them (data) as your customizations, which allow you to re-enter an app and continue where you left off. These data are useful for applications you use frequently, but not so good if you have applications that you have not touched in a month full of data. Delete them to free up some space: go to Settings> Application manager, then click on an application and, on the next page click "Delete data".
