The fourth beta of iOS 10.2.1 is available in public

It is now possible to install iOS 10.2.1 on its iPad or iPhone. This new version is not yet finalized, but available in public beta.

This is the fourth version of iOS 10.2.1, certainly one of the last if not the last before the release of the final version. Accessible to developers and users enrolled in Apple's test program, it can be downloaded to Apple's beta program portal or directly to OTA via a compatible device.

IOS 10.2.1 is not a major update. It focuses on fixes and improving the performance of Apple's system. The next innovations will arrive later with iOS 10.3 which should bring a mode cinema to iPad and iPhone. The latter would adjust the behavior of the device by lowering the brightness, disabling third-party sounds or blocking calls and messages, so as not to disturb the viewing.
