On September 10, in addition to the release of new products such as the iPhone 16 series, Apple also pushed the iOS 18 RC version, which users can update in the phone's settings-general-software update.
After upgrading to iOS 18 RC version, the version number is: 22A3354, after the update, in the mobile phone's Settings - General - Parts and Repair History interface, if the user has replaced the original accessory by himself, then the user can restore the "unknown accessory" to the genuine parts logo here.
However, it is important to note that if you are using an iPhone with Lost Mode or an accessory with Activation Lock enabled, the accessory will not pass verification.
In addition, some netizens said that after updating to iOS 18 RC version, there is an additional pause button when recording videos, and the phone is smoother when using it.
But here I would like to remind you that if you are currently in beta and want to wait for the official version to be released before upgrading to the official version, then it is best not to upgrade to the RC version, because if you upgrade to the RC version, you will not be able to receive the official version of the update push later, and the official version of iOS 18 will be released on September 17th.
In addition to the iOS 18 RC version, Apple also pushed the iOS 17.7 RC version, which has no new features added, and is mainly based on optimizations and fixes.
