Am I supposed to hear a doorbell sound from my iPhone ?
Welcome to the Forum Community, @H_Clay!
Depending on the type of device you are using you should get a notification when the doorbell is pressed and possibly, depending on your device settings, a sound also. There’s not a preset supplied “doorbell” sound with the Wyze doorbell itself - it will depend on house your Phone settings are configured.
There are also options with third party integrations such as Alexa if you have access there.
When choosing a sound in the app, the answer is no.
