I have just bought the Aosu V8S doorbell camera. The problem I am having is when someone rings I tap on the alert on my phone which brings me to where I can view the person outside and on either side I have a Red or Green Phone icon I push the Green one nothing will happen and in a few secs that screen is gone and back to the Home Screen if I were to push the Red Phone icon it works and hangs up. I have rebooted wifi deleted app reinstalled changed wifi from 2.4 to 5G tried on different phones even. The only work around is the person rings the doorbell the app opens to the screen where I see them then I press Red phone icon which brings me back to the Home Screen I push the play button wait for it to connect then push the microphone icon that says talk and now I can communicate both ways. It this the norm or I missing something.
Thanks in advance
