I own a Samsung Galaxy S4 with 32 GB SanDisk external SD memory. After about a month's use, I frequently started getting the message "Memory card unexpectedly removed". After googling, I learnt that this problem is being faced by many users owning a Galaxy with San disk memory. I have now bought a 32 GB Samsung SD card for my phone. I want to insert the new SD card into my phone and want it to work flawlessly with all the contents as it was before. For this, can I just copy the contents of the existing SD card onto my PC and then insert the new card into the phone and copy back the contents? Or is there any other procedure to keep the applications on my SD card running as before. Please clarify.
