FaceTime: It is the built-in video calling software of Apple's iOS operating system devices. It can access the Internet through wifi or cellular data to realize video call between two devices equipped with FaceTime. In 20 13, apple released a new IOS system, adding FaceTime audio, and the second function is FaceTime at night. From then on, FaceTime can realize voice call. FaceTime was officially announced by Apple CEO Steve Jobs at the iPhone4 launch on June 7, 20 10. According to the official, FaceTime can only be used for devices connected to Wi-Fi networks and does not support 3G networks. Therefore, Jobs said that operators need to work harder to make FaceTime support mobile wireless networks. At least at 20 10, FaceTime cannot support 3G, but only supports Wi-Fi.
Support applications:
FaceTime(3) FaceTime can be used between iPhone4 and 4 generation iPod Touch and Mac OS X; And neither the old iPhone nor iPod Touch supports this application. ?
In iPhone4, the call function has a FaceTime application built in, which must be activated by setting before use. The simplest activation method is to let iPhone4 users who have activated FaceTime dial the iPhone4 that needs to activate FaceTime through FaceTime. ?
Unlike iPhone4, which directly uses the phone number of its SIM card as FaceTime account, the fourth-generation iPod Touch needs to register an Apple ID as FaceTime account through its own email to use FaceTime. Because the fourth generation of iPod Touch does not have the call function, FaceTime is an independent application software in iPod Touch. ?
Similarly, FaceTime used by Mac OS X system is an independent application software, which requires users to install it independently and register an Apple ID as a call account by email. However, Mac OS X system does not need Wi-Fi to support its FaceTime function, and can only be used by connecting to home broadband.
Safety performance:? Martin Vigo, a security engineer at FaceTime Salesforce, reported this problem to Apple. The vulnerability is marked as CVE-20 16-4635, which is a common software vulnerability. Vig said on Twitter on Monday that other related vulnerabilities of FaceTime still need to be fixed. Apple is unlikely to release more vulnerability information before the fix is completed. ? As in the past, Apple advises users to upgrade to OS X El Capitan v.10.11.6 and iOS 9.3.3 as soon as possible to prevent attackers from exploiting this vulnerability. ?
