iOS 11 public Beta 4 is out now!

Apple has released the iOS 11 public beta 4 for iPhone and iPad. Users who are not registered developers can test pre-release versions of iOS for free.

Those who want to join the beta testing program can sign up on Apple's beta testing website, which gives users access to iOS, macOS, and tvOS betas. Betas should only be installed on a secondary device because the software is not stable and includes many bugs that have yet to be resolved.
