Android Question Joining Cisco Video Conference on Samsung smartphone

Hi I have a requirement to connect to a Cisco Meeting Server and join a video conference. The following code works well on a couple of vanilla flavoured Android 7.0 phones but when I attempt it on a Samsung Galaxy I am unable to join the meeting. I have tried on a couple Samsungs, an S8 and P7 with the same result. I get as far as entering my name to join the meeting but do not get passed the next screen actually into the meeting. I am using the following code:
Sub Activity_Create(FirstTime As Boolean)
Activity.LoadLayout("1")
rp.CheckAndRequest(rp.PERMISSION_CAMERA)
Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
If Result Then
rp.CheckAndRequest(rp.PERMISSION_RECORD_AUDIO)
Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
If Result Then
Dim i As Intent
i.Initialize2(
i.Initialize(i.ACTION_VIEW, "https://xxxyyyzzz,com") ' the Cisco Meeting server with meeting id and authentication
i.SetComponent("com.android.chrome")
StartActivity(i)
End If
End If
End Sub
