Apple released the fifth developer beta for iOS 12 on Monday, July 30, only 13 days after the release of dev beta 4 and 12 days after public beta 3. Until this release, Apple kept a consistent two-week schedule for developer beta updates, so we were a little surprised to see this one drop one day early.
The new iOS 12 developer beta 5 appears to mostly include bug fixes and security patches, including for an issue where you couldn't wake your iPhone if put to sleep while the brightness was fully dimmed as well as an issue where cellular data stats would continuously refresh. There is also a new haptic feedback for attempting to launch the app switcher when no apps are in the background.
If you want to update your iPhone to iOS 12 dev beta 5, you need to be a registered developer with a valid configuration profile. If you have iOS 12's new "Automatic Updates" enabled, you can let the software update overnight. To download the new beta right now, however, open the Settings app, tap "General," then "Software Update." Select "Download and Install," then follow the on-screen prompts to download and install iOS 12 dev beta 5.
While this beta release is only available to developers, public testers received the update the next day. Public beta 4 is exactly the same as this developer beta 5.
One of the biggest changes to come with dev beta 4 and public beta 3 was a patch for the popular game Fortnite. Fans of the game that installed iOS 12 from the beginning were quickly displeased to find that the software would cause the game to crash frequently, making Fornite near-impossible to play on the beta, but that's no longer an issue.
Here are some of the issues affecting previous beta versions that iOS 12 dev beta 5 fixes:
- An error message might appear while attempting to install an app. (41858048) — Workaround: Try installing the app again.
