Forgive me if the answer is obvious or if this is posted in the wrong place .... My Acer A500 is new. i bought a 16GB card and it will not mount. ive formated it using singleFAT and nothing. this has been done several times. i cant use markets "mount all" apps because those required root access which i dont have since i cant root without an SD card present . Ive done the "noob" troubleshoot i.e. reboot, poke the reset button, turn off and on with the card in and so on ... nothing. Ive cleaned the card and air dusted the sd card holder for any possible obstructions too. AND.... ive used a secondary MicroSD card to ensure the 16GB wasnt faulty and same result ... nothing . The acer does recognize the card under settings>storage>externalSDCard however theres no icon present and no mount/unmount option nor does it show when using ES File Explorer ... so the acer picking it up eliminates the socket not working WTF am i missing??!! genuine answers please im not a tech idiot who post about changing my wallpaper issues. i know what im doing i just needhelp on this one. thanks.
