how do i increase the amount of storage on my Galaxy S4

[AC Question]

I download a lot of books. I added a card which has 220g but I can't find out how to access it. Please help.

I don't think the S4 supports 200GB SD cards, only up to 128GB.

If it supports 128GB it supports SDXC, which supports up to 2TB.

To the original poster - you have to tell your book reader app to use the card. If it creates a folder on the card, use that folder to put your books in.
