Apple released the iOS 12.1.3 developer beta on Monday, Jan. 7, and the iOS 12.1.3 public beta followed shortly behind. Apple has been pretty on point with its public beta releases for iPhone, always releasing the same day as the dev version unless it's the very start of a beta build (i.e., iOS 12.1.3 beta 1), in which case they come out a day later.

If you're curious what iOS 12.1.3 beta 3 holds in store for you, you've come to the right place. The public release of iOS 12.1.3 beta 3 is exactly the same as the developer released earlier. But as of yet, there aren't any new features or other goodies hiding within this update, but we'll continue to investigate, especially since it's been about three weeks since the last beta release.

In its release notes, Apple only highlighted two resolved issues, the same two fixes highlighted in the second beta. It's safe to say most of the work is deep under the hood. These minor bug fixes and security patches are good, however, and should result in a more reliable version of iOS on your device.

To update your iPhone to iOS 12.1.3 public beta 3, you first need to have a valid public beta configuration profile from Apple. Then, if you have iOS 12's "Automatic Updates" enabled, you can let the software update overnight. To download the beta right now, launch Settings, select "General," then "Software Update."
