When the app is not showing the camera after a transaction is selected, it is most likely due to the permissions to the camera not being enabled. Please make sure you select Accept Permission when prompted for camera permissions or the app will not function correctly. The first time you use the app, after you select Accept Permission you will be prompted to allow TALK to take pictures. Please select ALLOW. If the permission was denied you can go to your phone's settings and find the TALK app to enable permission from there.
