I was trying to transfer a file via my LG optimus L9 (T-mobile) wifi-direct to my friend's Samsung galaxy S3, it got connected successfully however shortly after sending initialization, I got an error "Sending Failed".
then I tried the other way i.e. Recieving, but no success.
Later, I have tried with my another friend's Samsung galaxy Note, but no success.
nobody around having LG device with wifi-direct feature.
Can someone tell why is that going wrong?
