My iOS devise goes blank or freezes when someone rings the Nest hello doorbell. When it was installed, I payed for additional points simply to be sure of connectivity. I’ve read plenty of similar concerns so I thought that I would CHIME in. The delivery person is long gone before I get a chance to communicate.
Sorry for my late response. Thank you for all of your patience while waiting for a reply. I can definitely understand how frustrating your situation must be. I just wanted to make sure that your issue is addressed.
Please let me know if you need further assistance.
I and several others have been reporting that the Nest Hello goes off line when someone pushes the button. Mine recovers in a minute or so, but video of visitor is lost. I reset my nest hello, but it did not fix this issue.
