The Samsung Galaxy K Zoom makes such good photos, that I no longer use my "normal" camera. Unfortunately, it quickly became full by many pictures of my old little SD card. As a substitute I bought this 64GB SanDisk and no regrets. The smartphone is still extremely fast. Formatting problems or other problems did not occur when moving. I just copied all folders of the old SD card to the PC and then write the copied files from the PC to the new SD card. The time spent was 25 minutes 15 to copy the old and 10 to describe the new map.
