How would I play an MP4 on a USB Flash drive connected to the Nexus 10? The drive was formatted with Ubuntu with ext4 format. I have the MX Player but it does not see the USB Flash drive.

  • First question: Assuming you are using an OTG cable, is your phone able to detect the USB drive using a file manager?

  • Yes, I have an OTG cable. I haven't seen a file manager on this Nexus 10.

  • Try installing File Expert or something similar. Let me know if your phone can see it.

  • I've installed File Expert HD. I'm not familiar with this application but I don't seem to be able to find the USB Flash device attached via OTG cable.

  • See my latest answer. Try using a different OTG cable. Or try the app I suggested.

Usually Android can use only FAT32 because of permissions in ext file systems. If you have a terminal emulator installed + root + busybox you can do it like that:

  1. Open terminal;
  2. Type su to get root;
  3. Insert cable and flash drive;
  4. Type dmesg to get device name;
  5. Make a folder using your file manager;
  6. Try to: mount -t ext4 /dev/(device name) (path to folder you make);
  7. Enter the folder: cd (path to folder);
  8. Change the file permissons: chmod 777 (your file);
  9. Go to that folder with file manager and play.

Or you could just use StickMount.
