Recently I've encountered a glitch on my brand new Galaxy Tab 4. I bought the tablet plus the micro SD card less than a month ago, and already I'm having issues. Basically, every hour or so my tablet cannot detect the files on the SD card. The only fix I came up with was to un-mount and mount the SD card, but I still have issues with it. This isn't a huge inconvenience, since the all I have on the SD card is music, and the whole process of unmounting and mounting takes less than a minute, but it's odd that after such little time of owning the tablet and micro SD this has already happened. I can only assume that if I keeps doing this, then somehow it'll only get worse.
