Perhaps you have not thought about it yet, but you can connect on the Samsung Galaxy S6 a card reader with which SD cards, USB sticks and Micro SD cards can be read. Especially for the Samsung Galaxy S6 (no memory card slot) is this function very useful because data can be backed up fast to an external memory device.
The card reader is plugged in the Micro USB port of the Samsung Galaxy S6. You can then access via a file manager on the connected devices such as memory card or USB stick.
