Summary: I bought these mini sd cards for my granddaughters tablets. However, I was not able to move any of their apps to the card. I tried the card in my camera and as soon as I put it in and turned the camera on, it said the card was locked. I made sure that the lock on the side of the adapter was set to unlocked, but it still would not work. I searched the internet and tried numerous directions for unlocking the cards and nothing worked. I worked on this for 3 days.
