Please ignore the comment about the missing filenames, that was due to breaking out of the for loop. The problem is that the files selected by the user seem to have one substituted by a duplicate of another file selected by the user.  

Do you need to update the test content with a new one?

HTMLInputElement.prototype.files doesn't have guarantee of unique file names. File names are duplicated if multiple files were picked from multiple directories.

Yes I don't expect uniqueness from HTMLInputElement.prototype.files, but in my testing I am getting duplicates when I didn't select duplicates in the photo selector dialog spawned from input type=file so I added that uniqueness test in javascript to demonstrate the problem.

I have updated my test

#4,
Do you mean the size of 'files' array is greater than the number of chosen files?  Or 'files' doesn't contain some chosen files and does contain duplicates instead?

Hi,
I mean that if I select say 20 unique files (with unique filenames) the input type=file control gets 20 files, but one of the files is incorrectly repeated and actually has overwritten one of the other files. 

So I end up with a duplicate when querying HTMLInputElement.prototype.files and a missing file.

If the file input is submitted, the contents of files with duplicated names are identical?

Can you reproduce this issue on other devices?
Can you post screencast?

Hi,
Yes the contents of the file were identical. 

I can only reproduce this on Samsung SM-T580 tablets. But I have reproduced it on 4 different tablets of that model so far.

Thank you for providing more feedback. Adding the requester to the cc list.

It sounds like a bug of Samsung's picker dialog. You should report this to Samsung.
