    Default SD card unable to play SOME mp4 files?

    Not really a galaxy s4 issue.. however

    Just got a 64gb sd card. I have some MP4 movies that I want on my phone.

    The mp4 files work fine on my pc, they play just fine in any media player no issue.
    I then move them to the SD card, half the movies play fine, the other half either dont play at all and give me an error like "Unable to play" or work for hlf the movie and then stop and give me the same error.

    Same thing when put in the phone.. Half the movies work while the others either dont play or only half the movie plays before "unable to play".

    If I delete the file, then reinstall it, after 4-5 tries it sometimes works just fine..
    I clicked the "reformat" on the galaxy s4 for the card..

    Im at a loss, any ideas?

    Thanks in advance

    Are they bigger than 4gb? If so, format your card on your pc in the ExFat format. That supports larger file sizes and could be causing some of your issues. The S4 only formats the card in Fat32.

    Most are 1.5gb or less but I will try that, cant hurt to try.

    Try a different video player and see if that solves your problem. Here is a link to one.

    The files that work, seem to work on all video players.
    THe files that dont, wont even run on VLC. However if I move the files from the sd card to my desktop.. they then work fine?

    I will be trying he ExFat later this evening, just have not had the time yet.

    Thank you!

    Its not a player issue guys.. The files work fine on the pc, I even put them on another sd card and they work. They just dont work on this sd card.

    Trying to reformat now.

    was there ever a remedy to this...i am having the same problem... i have reformatted several times...in the device (note1)....i have a 64gb card that is recognized...but when i download music and mp4 to the card...most movies won't play...and the music files don't even show up...sometimes i go to the folder for mp4 and the phone only gives me the option to play thru music apps...sometimes i try to play a movie and the screen stays black and i hear static...i don't know what is going on....i can take another sd card out of another device and everything is fine with that one....i copy music and mp4 files to this new card and problems...i also got a new 32gb thinking maybe 64 was just incompatible...but that one is the same thing...so i think it is a problem w/ the format...i formatted the 64gb in the device first..and problems i tried fat32 from my laptop and lost half the memory... so i formatted again in the device it sees the memory but the files are all messed up...i keep hearing fat32...but that didn't work..i format in the device..but files don't play...only thing i haven't tried is the NTFS...

    any thoughts

    Same EXACT problem here. New Galaxy S4, new Samsung micro SD card (64 gb), and some .mp4 files play just fine, and some don't.

    On my macbook pro, I opened two Finder windows side by side, showing the video file as it lives on the micro SD card, and the file that lives on my hard drive. The video on my hard drive plays just fine in all the video players. Then I tried playing the same video file directly from the micro SD card, and no dice. If I delete the vid from the card and copy the working one from my laptop over, all of a sudden it won't work.

    Guys? Anyone? Someone HAS to have figured this out by now…

    Any luck with this? My micro SD card is made by Samsung, if that means anything...

    Same problem here. My videos are DRM-free, so that's not the problem. Also, they're only 50MB or less in size.

    I hope someone has the answer and sees these posts!!

    I had a similar issue. It actually happened with videos AND music. After trying many different remedies, nothing worked. My buddy suggested that problem is likely with the sd card itself. The one I was using was some brand I never heard before, so I purchased a scandisk, and everything works fine.

    Try another sd card if you have one. That would be my guess.

    I had the same problem.

    Try downloading the app Rescan Media from the Google Play store. The problem seems to stem from Android's file system doing something weird, not the file format or the player as you already know.

    I may have the answer to some of these concerns. I just had the same problems described above on my S4 with an external 32G card and solved the problem. The S4 seems to use the MP3 file "metadata" for its player listings. Just because you can see the file in the Music folder does not necessarily mean the metadata is OK within the file. I downloaded a free app to view and change the MP3 file metadata called "Stamp ID3 Tag Editor". I found that the "missing" files view in the Music player had missing names in the metadata. I supplied the names and woola! It showed up in the player. Hope this helps.

    It will be helpful if you can tell us the Editor that you used and how did you supply the names. I am having the same problem I searched for a Stamp ID3 Tag Editor and did not find it.
    Thank you
