iOS 10.2.1 beta 3 was released just a few minutes ago on iPhone, iPad and iPod Touch by Apple for iOS application developers. The new version of the operating system comes a few weeks after the previous version was released, Christmas forcing Apple to extend the testing program of this new version of iOS.
iOS 10.2.1 beta 3 is currently offered only to developers of applications for the iOS platform, not to users of the public beta testing program. In this idea, if you have the public beta version installed, you will have to wait until a suitable version is released by the Apple company, so do not rush to do any search.
According to the information provided by the Apple company, iOS 10.2.1 beta 3 only contains solutions to operational problems and improvements to the user experience. Apart from these changes, Apple does not announce anything else and it is unlikely that you will discover any visible changes after installing this version of iOS 10.2.1.
In fact, until now no major news has been discovered in iOS 10.2.1, so it is unlikely that Apple will make any important changes. The implementation of a new notable function is announced for iOS 10.3, so iOS 10.2.1 is most likely an intermediate update, intended to solve some problems and close some vulnerabilities.
UPDATED: watchOS 3.1.3 beta 2 and tvOS 10.1.1 beta 2 and macOS Sierra 10.2.3 beta 2 have been released.
