hi every one i've been having an issue with my external memory card recently,which i have a galaxy s4 and bout a 64 GB sd card for it and been using it for a while but some often times for no reason the sd card would be unmounted it self and had to mount it again. So i thought maybe the SD card was not good which was an after market and then i purchased an sandisk brand and i had no issue with mounting or unmounting the sd car any more and worked fine for a while and all of sudden when i wanted to transfer some of my pictures or musics from internal memory to the SD card it would not allow me, i've decided to format the card and the same thing and i bought another SD card also and the new one cant do anything either so i guess there is something wrong with either the phone or setting or something i can't make it to work.

any one can help me please?

Have you tried formatting the card while in your phone?

That sounds like a bad connection pin on the device side, usually what happens is your able to use it fine for a while but over time a bad pin will become lifted so it barely touches the card causing the phone to unmount it.

If you're crafty you can go in and realign the legs and test it from there but even if you get it to work its more likely to fail again soon, I'd put in for a claim and get it replaced.

yes several times and the very newest one i bought sees the sd card but can't neither create an folder from the phone nor move anything to the card.

actually if it was th pin it should do the same with the sandisk SD card also and it was not doing it and now it stays there but the issue is that i can't more anything into the sd card nor create an file in sd car also.

I know this has probably been resolved by now but when there's 3 out of 4 legs connecting it would recognize the card but prevent it from writing, either way it's sounding like a hardware issue over anything else and should be in for an exchange.
