iOS 10.2.1 beta 4 was released by Apple for developers of applications for iPhone, iPad and iPod Touch just two days away from beta version 3. The appearance is completely surprising because Apple is not in the habit of acting in this way with beta versions of iOS, but the release of the public version is probably rushed, so that's probably why we have more beta versions available more often.
Exactly as in the case of the previous version, iOS 10.2.1 beta 4 has specified as changes only solutions to operational problems and general improvements. No one knows how these changes affect the general functionality of our iDevices, but we can assume that the general experience of using iOS 10.2.1 beta 4 will be better than in the case of the previous beta build.
iOS 10.2.1 beta 4, like previous versions, does not bring visible changes to the operating system, but only internal changes, which are not easy to discover. The Apple company has not implemented new functions in iOS 10.2.1 beta 4, but only internal changes, so don't expect to find anything major visible, because you will be deeply disappointed.
iOS 10.2.1 beta 4 has been released
The public beta version of iOS 10.2.1 beta 4 has not been released by Apple yet, and this is normal because this build is probably not secure. In this idea, if you have used a public beta version and you want iOS 10.2.1 beta 4, I recommend you to stay away, because you may encounter problems with the terminals.
If you have another beta version of iOS 10.2.1 installed, then you can also install iOS 10.2.1 beta 4 right now using the system Software Update, Software Update. All you have to do is navigate to Settings > General > Software Update, Configurations > General > Software Update, and follow the instructions there.
