On my Galaxy S5 I want to upgrade to a larger capacity SD card. I know how to physically open the phone and remove and install the SD cards but I'm not sure if I have to move apps back to my phone memory first. Also, I'm not sure about whether to unmount first or not. Do I have to format the new card?
Could someone provide a step by step procedure to follow where the phone doesn't end up looking for needed files or data on the old card.
