A mobile phone is logging into my home. If I log in with another mobile phone, what will be displayed on the previously connected mobile phone?

If one mobile phone is logging in to the home application, and another mobile phone tries to log in to the same home account, the previous mobile phone will receive a notice or prompt indicating that the other mobile phone has logged in to the account. The specific notification or prompt form depends on the design and configuration of the home application.

Some applications may display a pop-up window, or inform users that another mobile phone has logged in in an in-app notification. Other applications may send notifications to users through push notifications or text messages. But the ultimate goal is to inform users that someone is using the same account to log in and use the home application, and enable users to take corresponding actions as needed, such as logging out or doing other operations.

It should be noted that family is a common term, and different applications or platforms may use different design and implementation methods to handle multi-device login. Therefore, the specific form of notification or prompt may vary depending on the application or platform.
