Qualcomm is disputing Apples claims about the iPhone sales ban in China that affected last years models (iPhone X, iPhone 8 and 8 Plus) and older ones going back to the iPhone 6s. Apple statement said that all iPhone models remain available and that iOS 12 doesnt infringe on the software patents in question.
Qualcomm clarifies that the courts ban isnt specific to an OS version, so it applies even to phones updated to iOS 12.
As for Apples other claim, this preliminary injunction apparently came info effect immediately. Apple is already appealing the ruling, but the ban remains in place while the court has another look at the case.
Thats how its supposed to work, anyway, Apple.coms Chinese sub-site still offers the iPhone 7 and 8 phones (the X has been discontinued).
Note that the latest iPhone XS and XR models are not affected by this ban (the suit was filed in 2017), but older iPhones still make up a significant chunk of Apples sales in China.
