iOS 9.2.1 was launched by the Apple company on January 19, and two weeks after its publication those from Cupertino made public a list of 100 security issues resolved by this version of the operating system for iDevices.
On February 5, the Apple company published this list in a support page of its own website, where all the security problems that were discovered by its employees or that were reported by various computer security researchers are listed.
Of these 100 security issues solved in iOS 9.2.1, 30 are related to the Safari browser which allows surfing the Internet, so we are talking about an application that had many more problems than benefits, as it seems.
The rest of the bugs covered by Apple via iOS 9.2.1 they are related to Apple Pay, FaceTime, Wi-Fi networks, the data encryption system and many, many other functions that are implemented in the operating system that works in our terminals.
If you are curious to find out the entire list of changes, well, you can find it on this page.
