Galaxy s5 micro SD card problem

[Dave557]

I just recently bought a 64gb SanDisk Ultra class 10, UHS Speed class 1. When I try to put mp3 files on this card under music, my phone will read some of the songs and the rest of the music files will say " cannot play this file on this device" when all the files are mp3 format. Also when I take pictures or videos and save it to the card the pictures don't come up as anything but a file with a question mark and the videos it comes up as an error message and it says this file cannot be played. I had to reset my phone about two weeks ago because the OS would not display. Could it be my phone or could it be the card. When I save mp3 or pictures on my phone storage it works. I was told by a Verizon Samsung technician that if problems with my phone continue to bring my phone in. My phone works fine but it's annoying that I can't put my own music on my phone and save my pictures and videos to my sd card.  Thank you for your time and I hope that their is a solution!

Did you format the card within the phone?

Try the card in another device, computer, tablet, camera and see if the problem is still there.

Good suggestion, I'll add you might try powering off the phones carefully remove the card let the phone set for about 10min. then reload the card as mentioned by Klue do a format even though usually the phone does this on installation of the card.. once formatting is finished it will say format complete or something similar

How are you putting files on the SD card? Plugging the phone in and putting them directly onto the SD card? Do you remember the eject your phone properly vs just unplugging it?

Thank you for all of your suggestions. I called Verizon today and a technical support specialist told me that they were having problems with SanDisk sd cards with all samsung products. But I'll try it on another device. I drop music files under the folder "Music" on my card and the same for photos. I always use safe eject when I unplug my phone from my pc.

I don't understand why it would not work on the s5 when it can support a card that size.. I'm stumped...
