Isn't Android File.exists() case sensitive?

Question

I've created a new folder "sdcard/dd" by:

File album = new File(albumPath);

if (album.exists()) {
   Log.d(TAG, albumPath + " already exists.");
} else {
   boolean bFile = album.mkdir();
}

And Again, I create the second folder "sdcard/DD" by the same code, but, this time the album.exists() returns true, which indicates the "dd" is equals "DD".

Anyone know why the File.exists() can NOT check the case of the folder name? Thanks!

As per Android documentation 'Android supports devices with traditional storage, which is defined to be a case-insensitive filesystem with immutable POSIX permission classes and modes.' https://source.android.com/devices/storage/traditional.html
