3. How can I access the storage/SD card after connecting the M7 to the computer?
A: M7 uses the MTP protocol and couldn't be properly recognized until the MTP driver installed.
Connect M7 to computer, open the disk named "FiiO"; Then, for Windows computers, copy the "SAMSUNG_USB_Driver_for_Mobile_Phones_1590.exe" file in the folder "Windows" to a local folder on the computer (such as the desktop) and double click to install it; For Mac computers, install the driver stored under the folder "Mac\OS MTP Client". After that, you'll be able to access the storage or SD card of the M7.
