2 horrible kind of problems – gt chat for Google Hangouts chat, call, gtalk Review

There are 2 problems with this app. The first one is that even when a person installs this app u cannot call them I was trying to call my friend a, and they installed this app but it will still say " this person has to install gt chats. The second problem is that it will only show ur friends not anyone else. These are the 2 things the app creators should fix.
