After a month and a half and a total of 6 betas, the official version of iOS 15.2 is finally here.
In the early hours of this morning, Apple released the official version of iOS 15.2 system, more than a month after the last official version.

The iOS 15.1 release system version number is 19C56 / 19C57, which is the same as the RC version number updated last week.
Users who have previously installed the RC version will not receive today's official version, which is equivalent to using the official version one week in advance.
If the beta user wants to upgrade the official version, delete the profile and wait for the next official version to be pushed.
The official version of iOS 15.2, as the second major version update of the iOS 15 system, also brings some new features.
Includes app privacy reports, legacy contacts, macro control for the iPhone 13 Pro, and new voice-activated solutions for music apps.
More importantly, the ECG function of the Apple Watch that everyone has been waiting for for three years has finally arrived.
Next, Xiaoguo will take you to see what new changes are worth paying attention to in iOS 15.2.
App Privacy Reports
The App Privacy Report is officially available on iOS 15.2.
Go to "Settings" - "Privacy" - "App Privacy Report" to browse your application access history.
With this feature, we can view the access history of each app within 7 days, including location, photos, cameras, etc., which allows us to better manage the access rights of the app.
iPhone repair history
After updating to the iOS 15.2 release system, if your iPhone has been repaired, the "Parts and Service History" option will appear in "About This Mac".
The system will be prompted based on the authenticity of the accessory you replaced, and if it is officially genuine, it will display "Genuine Apple Parts".
If you display a gray exclamation point in the parts column, the part is not the original, or it has been installed on another iPhone, and it was not installed successfully.
Legacy contacts
The "One Click Death" feature is also online in the official version of iOS 15.2.
Users can go to "Settings" - "Apple ID" - "Password & Security" and add a "Legacy Contact".
Heritage Contacts have access to photos, videos, notes, documents, and other personal information.
Hide emails
After upgrading to the new version, users can turn on Protect Mail Activity in Mail to hide personal IP addresses.
You won't be able to see your IP address, which greatly improves privacy.
Voice-activated subscriptions
Apple has launched a new "voice control solution" subscription method for music apps, priced at 5 yuan / month.
Once users subscribe to the program, they can control their music playlists through Siri.
You can also call Siri to make music recommendations based on your preferences, or to access recently played music.
SOS Emergency Contact
With this update, the SOS emergency contact function has been further optimized to make calling more convenient.
Users can now enable auto-call by quickly pressing the side button 5 times, or by holding down the side button and volume button at the same time.
In addition, Apple has increased the reaction time of this feature from the original 3 seconds to 8 seconds.
When the emergency call function is triggered, the user can manually cancel at any time during the 8-second response time to avoid false positives.
Macro control
In the iOS 15.2 beta system, Apple added an opening key to the "Auto Macro" function of the iPhone 13 Pro series cameras.
The user can choose whether to display the auto macro switch in the camera through "Macro Control" in the settings.
ECG
With the arrival of the official iOS 15.2 system, the much-anticipated ECG function has also been officially launched.
ECG features are only available for Apple Watch 4 and updated watches.
This feature is available after updating the iOS 15.2 and watchOS 8.3 release systems.
Start by opening the Health app on your iPhone.
Go to "Browse" - "Heart" - "Electrocardiogram (ECG)".
Click "Settings" and follow the prompts.
Then put on your Apple Watch, making sure the back of the watch fits snugly against your wrist while placing your arms flat on the table or on your lap.
Open the "Mobile ECG Atrial Fibrillation Tips" app, touch the digital crown with the fingertip of the other hand, and wait patiently for 30 seconds to get the specific data of the user's current heart rate.
In addition, the "universal control" function that iPad and Mac users are most looking forward to has also ushered in the latest news.
According to Apple's official website, this feature will be delayed until next spring.
So you'll have to wait.
In addition to the new features, iOS 15.2 also fixes some bugs that existed on previous systems.
According to Apple's official update documentation, iOS 15.2 fixes the following bugs:
1. When VoiceOver is running and your iPhone is locked, Siri may not respond;
2. When viewed in a third-party photo editing app, ProRAW photos may appear overexposed;
3. When the iPhone is locked, the HomeKit scene including the garage door may not be able to run from the CarPlay car;
4. CarPlay may not update the "Playing" information of some apps;
5. The Video Streaming app on the iPhone 13 model may not load content;
6. Microsoft Exchange users' calendar events may be displayed on the wrong date.
According to Xiaoguo's weekly experience of using the RC version, iOS 15.2 performed well overall, although it encountered some bugs in the beta version, but Apple quickly fixed it.
