I recently purchased a 512 GB SD card from eBay for 10 dollars. I used it for my Samsung Galaxy Tab A and attempted to transfer all of the apps stored in the tablet to the SD card at the same time. Later on, the tablet froze and restarted itself for some reason. After this, I found out that all of the apps that I was trying to transfer had a different thumbnail and I wasn't able to open them (possibly corrupted?). I then tried to transfer the remaining apps to the SD card, but was given the caption "Insufficient storage on micro SD card. Now every time I put the SD card in my tablet, it makes the tablet freeze. Why, and what should I do?
