After the Public Beta release last week, Apple has now released the iOS 12 Developer Beta 3 update for all iOS 12 supported devices. If you already have the iOS 12 Beta profile installed on your iPhone, head over to Settings » General » Software updates to download iOS 12 Beta 3 to your device.

The iOS 12 Beta 3 release notes mention a handful of fixes for the existing iOS 12 problems that users have been facing since the first Developer Beta release. If you’re running iOS 12 Public Beta on your iPhone, this isn’t the update for you though. You need to wait for a few days for the Public Beta 2 release.
