Apple released an IOS 12.5.1 update to fix a problem with the new covid-19 exposure notification feature for the old iPhone in December.Previously, Apple released the key exposure notification function of IOS 12.5 for devices that cannot be updated to IOS 14. Users of older devices are encouraged to update and check if their region participates in the covid-19 tracking API.
This update applies to:
iPhone 6 Plus
iPad mini 2
iPad mini 3
When using the exposure notification API, the user will be prompted to select the living area to determine whether the function can be used. When the function is turned on, the devices between users will exchange codes in private and safely to mark the people they have contacted.
If the user or others test positive for covid-19, the person concerned will record this in the exposure notification system. After doing so, everyone who exchanges with the device will be notified of the exposure.
