Apple has released iOS 12 beta 2 for public beta testers, now available to download. The new update should address a variety of bug fixes, while also introduce features debuted in the latest beta build released earlier this week for developers. iOS 12 public beta 2 is the same build as iOS 12 beta 3 for developers.
Public beta testers can install this iOS 12 beta update by going to Settings > General > Software Update on their iPhone or iPad.
Some bugs associated with iOS 12 beta include GPS location issues, missing associated numbers in iMessage settings, plus also random resprings when waking up iPhone X. This release hopefully should address these bugs and more.
