I have HTC explorer ai310, my SD card is working normally in my laptop but not on my phone though it is shown mounted on my phone and also showing total and empty space of sd card. what should I do to access all datum sir?
Copy card contents to your PC if the data is important.
Now try formatting the card on your phone preferably, or on your PC if you don't know how to format it on the phone.
If card still doesn't work on your phone, throw card away and buy a new one.
