Hello my name is ***** ***** help you with your question...
In order to help you better with your request, I need a bit more information:
- Although these MicroSD cards are becoming unreadable on this Tablet, when you get to insert them on a Windows based PC, does it show any type of error message? is it unreadable? or undetectable by the PC? I need to know if the tablet is corrupting the file system in the card.
- Have you fully formatted the MicroSD card on a Windows based computer prior to be inserted into the tablet?
