How to use the memory card
A memory card can be used in two different ways:
- as memory for internal storage,
- as memory for external storage.
Let's see the difference:
The mode for external storage is that practiced by all those who pass their memory card from one device to another to view their multimedia files. The card is read by other devices but can not be reformatted with the portable storage memory mode.
This type of storage is recommended with cards of the lower classes (2, 4 and 6).
The use as memory for internal storage is adopted by those who want to increase their internal storage memory to install games and applications.
The card must be formatted on the device that will receive it afterwards. The switchover will be done automatically.
It should be noted that Android formats a card in such a way that it will be impossible to read it on another device.
Turn an external card into an internal storage
This operation is possible thanks to the Adoptable Storage function which came into being with the arrival of Android 6 but which is not widespread on all smartphones.
The storage of applications is done in the device while the storage of multimedia files can be done on the card. It should be noted that you will take cards of class 10 or more.
