    Default sd card not being detected by galaxy s 3 mini

    Hi I just got a samsung evo microsd card to put music onto my phone and after I had put it into my computer and successfully downloaded my music on it I tried to put the card into my phone and it wont detect it in the slightest. I downloaded an app thats supposed to detect the sd card and allow you to manage the data on it but it can't because it cant even detect that there's a card in the phone. Please help and thank you!

    When inserting the card, was the phone powered down?

    Did you then mount the card in Settings > Storage after booting up?

    Also when removing the card, unmount it first and remove after powering down.

    It's a 2 step process each way to:
    1. Preserve the data on the card
    2. Protect the card from damage
    3. Allow the phone to know when it needs to read the data from a card and index the content

    I did that and when I tapped the mounting/unmount button it wouldnt work still. Its like the phones sd card reader is broken but I just got the phone a month ago and never used the sd card insert until now. Im at a loss...

    Does the card work in anything else like a PC?

    Yes I successfully downloaded music onto it right before I tried putting it into my phone.

    Might be a card incompatibility...

    What phone model? What microSD card exactly?

    OK... The mini will use that class 10 card. Now about formatting. Did you let the phone format the card or your computer? Is it Fat32 or exFat?

    Formatting makes a difference in a huge number of factors:
    • max file size (individual files)
    • max file name
    • maximium # of file names stored in file table for indexing

    Among other issues...

    Start here: What format for sd card
    Maybe poke around the Galaxy s3 forums in general or do a site search here at Android Central for "SD card format."

    Cant remember what format but wouldn't the phone still be able to recognize that there was a card in it at all? Ill try reformatting but I think the problem is with the phone itself.
