iOS 12.5.1

I believe that some fans who have been following Mingmei Infinite to this day should know that Apple has been on holiday before, and it feels that we have not received the update push of the iOS system for a long time.

Apple released iOS 14.3 a month ago is the latest official version of the system, in addition, Apple also launched the iOS 14.4 beta system.

Now, Apple has finally released a new version of the system update, but only for old models.

iOS 12.5.1

First of all, what Mingmei wants to mention is that Apple’s iOS system is known for its smoothness and safety. Apple’s iOS system is still doing a good job in upgrading and updating. iOS system upgrading and updating also take care of older iPhone models, such as the latest. The iOS14 system supports all iPhones that can be upgraded to iOS13.

Of course, there are still many old iPhone models that do not support iOS14 system upgrades, such as iPhone6 ​​and iPhone6 ​​plus phones. Now Apple has pushed the official version of iOS12.5.1 upgrade to iPhone6 ​​and other old models. The updated version number is 16H22. Upgrade update package The size is 199MB.

For this update, the biggest feature is that the bug in the “exposure notification” function has been fixed. After the previous iOS 13.7 system, this function can be used on iPhones. The biggest function of the exposure notification is that it can use alternate random Bluetooth symbols to determine whether the user may be exposed to a patient who declares to have been infected with COVID-19 without infringing on privacy. This function helps users to detect and prevent COVID-19 to a certain extent. When this function appeared in the early stage, it was also well received by users.

iOS 12.5.1

Last month, Apple pushed the iOS 12.5 system update to the old iPhone/iPad, which mainly brought the exposure notification function.

So how is the COVID-19 exposure notification used?

When the user enables this feature, the device will periodically send a beacon containing a random Bluetooth identifier via Bluetooth. When two people get close to each other, their phones exchange and record these Bluetooth identifiers.

If someone tests positive for COVID-19, they can proactively report the positive test to the exposure notification app in their area. The Exposure Notification API will also download a list of beacon keys that have been verified as belonging to users who are confirmed to be positive for COVID-19, and check with the list. If there is a match, it may notify the user and inform the user of the next action.

Exposure notification API is the touchstone of privacy. The biggest privacy protection of Apple and Google’s Exposure Notification API is that location data has no role in the way they work. The two companies stated that these applications should collect as little data as possible. This Bluetooth-based approach does not require location data.

iPhone 6

In addition, it is worth mentioning today that Apple has extended the exposure notification function to iPhone models that do not support iOS 14, including the iPhone 6, which set an iPhone sales record.

After seeing this notice early in the morning, many netizens said that my iPhone 6 could be used for another two years. In fact, what many people don’t know is that the iPhone 6 and iPhone 6Plus in the post-Jobs era are the highest-selling series in the world so far, and this series has the most old users. And this time, iOS 14 does not support the iPhone 6 series, but supports the iPhone 6S series. So many people say that the iPhone 12 series will be replaced by the old users of the iPhone 6 series. Now iOS 12.5.1 is pushed, it is estimated that these old users will still be able to use it for a while.

Specific iOS 12.5.1 models that can be updated include: iPhone 5S, iPhone 6, iPhone 6 Plus, iPod Touch, iPad Air, iPad mini 2, iPad mini 3.

In addition, in other aspects, the updated iOS 12.5 also provides users with important security updates, and Apple recommends that all users install it. However, some of these features are not available in all regions, nor are they applicable to all Apple devices. Users who hold these older models can find the system version update in Settings-About Phone, or open the latest version of iTunes on the desktop and press “Shift + Update” to update.

In addition to the “exposure notification” repair, there are currently no repairs in this version in terms of battery life, power saving and performance.

However, it can also be seen from this that Apple really puts user safety and privacy in the first place. After all, for some brands, a machine produced in 2014 (taking iPhone 6 as an example) can still perform Function increase and optimization, this is really not common in the entire mobile phone industry!

Of course, don’t expect Apple to take care of the old models. They will definitely give up when they should. Unless there is a major problem, you see that the previous models of the iPhone5 (including it) series have now been abandoned. Of course, Apple has done enough to maintain the old models. No one brand in the Android camp can do this at all. Don’t let the models from five years ago, even the ones from three years ago, have several Android camps that can be updated and maintained.

In addition, for the iOS14 system iPhone, Apple recently closed the iOS14.2 system and iOS14.2.1 system verification channel, all iPhone phones that have been upgraded to the iOS14.3 system will not be downgraded to the iOS14.2 system Up.

Finally, what Mingmei Wuxian wants to say is: Although Apple suddenly released the official version of iOS12.5.1 today, it really warmed the hearts of our fans, but with the recent frequent release of this situation, What many of our apple fans should do now is to protect themselves and their relatives and friends from infection.

In this regard, if you have anything to say about the official version of iOS12.5.1 released by Apple today, please leave a message in the comment area to Mingmei Unlimited to participate in the discussion!
