Horizontal colour lines during pre roll

Hi @user32656. You can try rebooting your Doorbell from the Ring app to see if that helps. Also, verify your Doorbell has a good signal strength, also known as RSSI. If you have tried these steps and are still having the same concern, give our support team a call at one of the numbers available here for further assistance. If you are outside of the US, please visit here to see how to contact support.
