Apple today pushed the iOS 15.7.5 update (internal version number: 19H332) to iPhone users. This update is 14 days after the last release.
It should be noted that due to the configuration cache problem of Apple’s regional node servers, there may be a slight delay in the detection of upgrade updates in some places, usually within half an hour, not too long.
In the official update log, Apple only stated that it has enhanced security features and has not introduced any new functions/features. Apple says the iOS/iPadOS 15.7.5 update provides “important security fixes” and recommends that all users upgrade as soon as possible.
The list of devices applicable to the iOS / iPadOS 15.7.5 update is as follows:
