The official version of iOS 14.0.1 has just been released, and Apple has suddenly “started” on iOS 14 devices. According tomedia reports, Apple has stopped system verification for iOS 14, which also means that devices that have upgraded the system are not allowed to downgrade in previous versions. Stopping signing means that users can no longer download outdated operating systems from Apple’s servers, and Apple is used to stopping signing old code regularly after the release of a new version of iOS to prevent users from installing past iOS versions.
This approach protects users from new threats and ensures that the device is running the latest software.
iOS 14.0.1 fixes an error that could cause a third-party application to be set to default, and problems occur after the iPhone restarts, in other words, the iPhone will work fine after changing the official default app.
This update also addresses a bug that may prevent the iPhone from connecting to some Wi-Fi networks and fixes an issue that may prevent some mail carriers from sending e-mail messages.
