Guys this trick is for specially facebook mobile users.
 

Suppose by chance you sent a friend request to a wrong person and you want to cancel it but in fb mobile view there is no option for that.But i found a trick-
 

1. First go to that users profile.

2. Block that person

3. Unblock it again.

 

Friend request will be cancelled automatically.
