However, although there was no new iPhone in the press conference, Apples official website, as previously expected, has just delivered the official version of iOS 12.1 OTA updates in the early morning, suggesting that the iPhone XS series and XR users upgrade as soon as possible, because there are a lot of targeted optimization.
If youve upgraded to the latest version of iOS 12.0.1, the size of the OTA update youve received is about 484.3M. As you can see from the official update documentation, youve done a lot of fine tuning for the iPhone XS and XR series, such as camera preview for depth of field control, improved mobile network connectivity. Connectivity and other very practical new features, of course, for the iPhone 8, iPhone X and other models also have some optimization, specific information will not be detailed, you can see the official documentation.
Of course, its also important to note that while the probability of an iPhone updating directly via OTA is small, its safe to suggest that you backup it with iTunes and then update it.
