Apple launches iOS 12.5.1 to fix covid-19 tracking system

Even if Apple wasn’t present at CES 2021, Apple decided to pick the opening day of one of the biggest technological achievements to launch the iOS 12.5.1 update for older iPhone models. According to the company, it “corrects an issue where exposure reports could incorrectly display the language of the registration profile”.

IOS 12.5 was released along with iOS 14.3 last December, and both brought support for reports of exposure to the new coronavirus. These systems send an alert from anonymous Bluetooth IDs at close range.

These are the devices that should receive the update released today:

iPhone 6 Plus
Iphone 6
iPhone 5s
iPad mini 3
iPad mini 2
iPad Air
iPod touch (6th generation)
To install the update, go to Settings> General> Software Update and choose ‘Download and Install’. You can also do this through iTunes, connecting the device to a computer.

Tracking the coronavirus

For those who don’t know what an exposure notification system is, it was created by Apple and Google as a way to use cell phones to alert the user of contact with a person infected with Covid-19.

The system relies on a tracking application (Brazil has one, the Coronavirus – SUS), for which cell phones generate their own anonymous identification. When two people with cell phones meet, they exchange this code via Bluetooth, that is, each smartphone generates its own code and stores the code sent by the devices of the people it interacted with.

In a positive test for covid-19, the patient uploads these anonymous codes to a server. This in turn will send this code list to all smartphones with the tracking application. If someone recognizes their own code in that list, the user is warned that they have been close to a person infected with SARS-CoV-19 for sufficient time and distance to allow contamination.
