I have 16 GB on my samsung galaxy s5, and have a new SD card that is 64 to install. I want to add all my old info onto this card and not loose anything. How do I do this? Would really love step by steps.
I have found that the Sd cards are not always reliable. One of the best ways to backup your phone is by computer. I use smart switch and do a total backup of the phone. It will save everything and you could always put it on a flash drive for safer keeping.
kathy65793 makes a good suggestion, but additionally there are a number of free programs/apps for PC and Mac that can copy the old card to the new card via memory card reader.
Do a Google search for "free copy SD card" "free duplicate sd card" "free clone SD card" "free clone SD card" etc. which should give a number of free options to install a program to computer and then format new card and copy the old in it's entirety. Sorry I can't be more specific than this but it has been a while since I have done this myself....
