This answer would be better if it explained a little bit about why it's "emulated".
I believe Android does some hack to fake a FAT fs that's actually backed by something better, but I don't know the details and clicked this question hoping to learn something new. Here's an excellent article about it: xda-developers. Read Android's Storage Journey for details, the summary is: Early Android devices were short on internal storage and relied on physically external SD cards that traditionally use FAT family of filesystem to ensure compatibility with most of the PCs refer to Microsoft's dominance on PC world.
UMS exposes the device at block level and disconnects the SD card from Android framework un-mounts , thus making whole data unavailable to apps and possibly breaking many functionalities.
MTP doesn't expose block device but works through software stack. MTP host runs on Android as an app android. Execute the commands again: See the difference in permissions of same files and directories.
Irfan Latif Irfan Latif I think I misunderstand the part about MTP. If not, couldn't Google use ext4 filesystem for FUSE implementation as that could also enforce permissions checks needed for an app to access only their data in shared storage? Firelord when discussing emulation, focus isn't on MTP implementation.
Google already made changes to MTP protocol to meet certain Android needs and possibly they could implement it through some native Linux filesystem. But the point is we need a FAT-like permission-less filesystem that used to be in the early days of Android to ensure backward compatibility and that meets the design of Android's External Storage concept. I've made an edit to elaborate my point. I was having a similar issue, I could find the location, but no videos would populate. I have to change the usb connection mode from Camera to Media I know, duh.
