I was asked whether to use a "smartphone storage" or "external storage"!? -Why that I can't hear now

When I tapped the notification that appeared after inserting the microSD card, I was asked if it was a "smartphone storage" or "external storage"? That is, the purpose of use is to initialize the microSD card (format).I'm asking.If you don't want to initialize, cancel, or if not.

"Smartphone storage" is selected when using the MicroSD card area to be added to the internal storage (flash memory with a built -in terminal).It is almost impossible to physically add internal storage, but this method can make up for the lack of internal storage.It can be used not only as photos, videos, and music, but also as an app storage area.

However, internal storage microSD cards cannot be used on other terminals.Only Android devices that have been used in internal storage can be used to use the data saved in the microSD card.Note that if the terminal that executed the internal storage breaks down, you will not be able to access the contents saved on the microSD card.

On the other hand, the "external storage" is removed and formats in a format that can exchange data with other PC/smartphones.It is not available as an app storage area, but you can save regular files such as photos, videos, and music.

In other words, if you use a microSD card as an internal storage assistant, select "Smartphone Storage", and "External Storage" is selected as data replacement with other PC/smartphone.Either choice is accompanied by initialization, so run only with a microSD card that can be erased immediately after purchase or deleting data.
