Turn On Exposure Notifications
In response to the COVID-19 pandemic, both Apple and Googe added a new feature to iOS called Exposure Notifications. The system generates a random Bluetooth identifier that is shared between devices when they come close enough together when out in public. These identifiers are saved for a short period on each phone. If a person becomes sick with COVID-19, the tracing system can then use these identifiers to notify all the people who had close contact with the COVD-19 patient. Though it is available in the iOS Settings app, you can only use Exposure Notifications in those states and geographic areas that support this feature.
