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. receiving, but no success.
Later, I have tried with my other friend's Samsung Galaxy Note, but no success.
Nobody around me has an LG device with WiFi Direct feature.
Can someone tell me why is that going wrong?
