Apple Liuwen always crashes by pressing SMS.

Compatibility of application software plug-ins

As mentioned above, Apple's IOS system is closed. All APP applications running on the IOS system must pass Apple's official certification test. Only the tested app can be downloaded, installed and used by other users in Apple's APPstore. Some APP applications that affect the security of Apple systems or users are banned from going online by Apple. However, jailbroken Apple phones cannot install these APP applications, such as interface beautification, address book management tools, SMS management tools, file management tools and other app plug-ins. Because these plug-ins have not been strictly tested by a third party, it may lead to compatibility problems in the system, which may lead to the automatic shutdown of Apple's mobile phone. The solution to this situation is to uninstall the recently installed APP application plug-in.
