Apple promotes iOS 9.3.5 update and fixes security vulnerabilities and recommends all users to upgrade.

Early this morning, Apple pushed the iOS 9.3.5 update to all iOS users. It wasn't a major feature update, but the summary of the update said, "all iOS users are recommended to update." This kind of marking is particularly rare for system updates in the version, and the most important reason is that there has been a major security hazard in iOS recently.

This major security hazard stems from the discovery of powerful spyware on iPhone 6, through which users' iPhone may be subject to continuous mobile attacks, and hackers can use the software to obtain information about various applications on their phones.

It is precisely because of the significant security impact of this vulnerability that Apple recommends all iOS users to update the system.

There is also news that this will be the last iOS 9 system before the official version of iOS 10. The official iOS 10 is expected to go on sale with the new iPhone in early September.
