Apple today pushed the iOS / iPadOS 15.7.4 update (internal version number: 19H321) to iPhone and iPad users, 63 days after the last release.
It should be noted that due to the server configuration caching problem of Apple’s regional nodes, there may be a slight delay in detecting the update update in some places, usually within half an hour, not too long.
The version number of Apple iOS / iPadOS 15.7.4 is the same as the previous RC preview version. This update is mainly pushed for devices that cannot be upgraded to iOS 16 and iPadOS 16, and there will be no major feature improvements, only bug fixes and optimizations. Devices include iPhone SE (1st generation), iPhone 6S / 6S Plus, iPhone 7/7 Plus, iPod touch (7th generation), iPad mini 4 and iPad Air 2, and more.
