I have a Samsung Galaxy S4 Mini running Android 4.4.2 (KitKat), and a computer running Ubuntu 12.04.
When I plug the phone into the computer using the USB cable that came with the phone, the phone gives a notification that says "connected as an installer", and it shows up on my computer as a folder containing some unidentifiable files. When I click the phone notification I can change it to connect as either "Media device (MTP)" or "Camera (PTP)".
When I connect with MTP, the phone shows up on my computer as a folder containing all the same folders that it actually contains (as viewed from ES File Browser on the phone), but from the computer those folders all appear empty.
When I connect with PTP, the phone again shows up on my computer as a folder containing all the correct folders, and this time most of the folders' contents are shown as well. However, only image files seem to be shown (for example, I see .gif, .jpg, and .png files, but not .ogg or .mp4 files).
So, two questions:
- Is it possible to make the other files show up, or not?
- If not, is there any app that makes it possible?
