This article addresses when set up of a Ring product on an Android device either fails, or gets stuck in the middle of the setup process.
The likely source of the trouble you are experiencing is a setting in some Android devices called Smart Network Switch.
This feature is also sometimes called "Mobile Network Switch" or "Auto-switch to mobile network."
To remedy this situation, you'll need to manually navigate to your Wi-Fi settings.
On most Android devices, you can swipe down from the top of your screen to reveal a menu like this:
To get to your Wi-Fi settings, tap and hold on the Wi-Fi icon, until you land on a screen with a list of Wi-Fi networks. If you're in the process of setting up your Ring device, select the Wi-Fi network of your Ring device, which will start with one of the following prefixes: "Ring-", "Chime-", or "ChimePro-"
What you may see is a message like the one below.
The exact message and wording you see may vary due to the numerous makes and models of Android devices. The important thing to look for is a message warning you that the network you are trying to connect to doesn't provide internet access.
Look for the option that will enable you to connect to this network (regardless of its lack of Internet connection).
In the case of the prompt below, you would simply tap OK and then return to the Ring app:
Setup should then complete successfully.
If you don't receive a prompt like the one above, another thing to look for is a feature called Smart Network Switch.
If Smart Network Switch is turned on, your Ring product will almost definitely not set up successfully.
On the device picture below, Smart Network Switch is at the top of the Wi-Fi screen.
On other devices, you may need to locate an Advanced Wi-Fi Settings screen and look for the Smart Network Switch feature there.
Turn this option off, then return to the Ring app and resume setting up your Ring device.
This should solve any issues you were experiencing. Note that if you turn Smart Network Switch off, you can turn it back on after setting up your Ring device.
