Facebook sdk login issue on device

I'm working on integreting fb login to my game FB.LogInWithReadPermissions (permissions, AuthCallback); When I test on device and show logcat: sending to Unity OnLoginComplete({"key_hash":"xxx=\n","last_refresh":"1462668978","declined_permissions":"","permissions":"user_friends,public_profile","user_id":"1167274103304653","expiration_timestamp":"1467848554","access_token":"xxx","opened":true,"callback_id":"3"}) But issuse is that AuthCallback not called, logcat just show sending to Unity OnLoginComplete and stop there. Anyone else has the same issue?
