Thanks for your interest! Right now Lampyre is still in beta-testing so there migh be some mistakes present. We’d be really grateful if you could report them here: https://lampyre.io/support. Then we’ll be able to make a better analytical instrument for fulfilling your tasks.
There are different OSINT methods to find info on a Facebook profile by just a phone number.
We’ve recently updated the list of our requests, so please try to repeat your actions.
Also there might be that accounts with hidden friends were the input parameters for the “Facebook common friends by account username or ID” request. If so, this request is not able to get any results.
In order to accomplish you have to do the following: first execute the “Facebook account hidden friends by account user name or ID” for the accounts with hidden friends. Then execute the “Facebook account friends by account username or ID” for the accounts with open friends. After this look into common friends on a combined graph.
Unfortunately, currently we don’t have any tool which would show the request progress. And some of our requests would take a while, so you’ll have to wait patiently for them to be finished.
