HELPFULL TRICK FOR MOBILE FACEBOOK USER TO CANCEL FRIEND REQUEST...

Suppose by chance u sent a friend request to a wrong person and u want to cancel it but in fb mobile view there is no option for that.BUT I FOUND A TRICK
First go to that users profile.BLOCK THAT PERSON AND UNBLOCK IT AGAIN.

FRIEND REQUEST WILL BE CANCELLED AUTOMATICALLY

I know there will be comments switch to full site etc. Etc..BUT IF NOTHING WORKED THIS IS LAST OPTION.I found it useful so i shared it...
