Android file creation permissions

I have tried that form the smb.conf, but it seems to be overridden by the app.
Here is the snipit from my smb.conf for the share:

[lab-test]
	comment = Lab test
	path = /mnt/lab-test
	browseable = yes
	public = yes
	guest ok = yes
	share modes = yes
	create mode = 666
	directory mode = 777
	writeable = yes


Just so you know this is a test for a project I am working on, hence
the share comping from /mnt and the very laxed permissions. So please
no comments about it being really insecure.
