Got my mid 9742 two weeks ago, very happy with video, audio and 9.7'' size. However, there are 2 problems bothering me, I am the first time android user, not sure is tablet's problem or not.
1. mini SD card. I bought a 32 g mini sd card, mid 9742 recognized it right away, but when I tried to copy a picture from the internal storage to the mini SD card, it won't work. However, it seems I can copy somthing from mini SD card to the internal storage. I use ES File Explorer.
The miniSD card is called a microSD
Sounds like your microSD card is set to ReadOnly ( needs to be set to Read/Write)
What Name microSD Card?
What Class microSD Card?
Also, please take time to explain how you are trying to copy to and from.
Example - Is the microSD plugged into your tablet or plugged into your computer?
If the microSD card is plugged into your computer Using an Adapter ,
take a close look at the Adapter amd make sure its no the the LOCKED position
(there is a little slider on the side of the Adapter)
if the Adapter is locked position, slide to the Unlocked position.
(push the slider down to make it Read/Write).
