Apple is on the safe side with once-weekly releases for iOS 11.4.1 Beta. Exactly seven days after Beta 3 came out, Beta 4 was delivered to developers and public beta testers on Monday, June 25th. As before, there are no new features or known enhancements or bug fixes. Apple has confirmed that iOS 11.4.1 will only be used for enhancements below the surface, as the beta version of iOS 12 has already been released.
There is no information in the iOS 11.4.1 Beta 4 release notes for developers. The only thing Apple has noticed is that there are "bug fixes and improvements" according to the install screen, and so far that has been the case for the entire iOS 1
To install the latest version of iOS 11.4.1, you must be a public beta tester developer with a valid configuration profile. Once done, open the Settings app, tap General, and then choose Software Update. After that, just follow the instructions on the screen to download and install iOS 11.4.1 Beta 4 on your iPhone.
Overall, iOS 11.4.1 was very boring from a user-facing direction. And that's probably because iOS 12 will be released to public beta testers very soon, in late June, and there are a lot of new features to play with.
