Apple announced that App in App Store in China does not support Callkit function.
Apple has announced to all iOS developers that all App on App Store in China cannot support Callkit.
it may be unfamiliar to you to mention Callkit. What you are most familiar with is that under the lock screen interface, applications such as Wechat can directly display "reject" and "answer" full-screen interfaces, which is almost no different from the traditional phone call experience.
However, according to the regulations of the relevant departments, this function must be blocked in China, and this has the greatest impact on applications such as Wechat, because when there are voice or video calls, under the frequency lock interface, you will not see the direct kind of clear prompt to answer or hang up. Instead, you will need to enter the App for a new message.
in addition to iOS, Android phones actually provide this function, and the network call interface pops up directly on the lock screen, which is more or less inconvenient for users, but considering the traditional call business, it is easy to understand.
