Apple Releases iOS 12.3 Public Beta 4 for iPhone to Software Testers

So far, the iOS 12.3 public betas have been on the heels of the developer betas by just over a day each time, but not anymore. Apple just pushed out iOS 12.3 public beta 4 today, April 29, just hours after the same dev version came out, meaning it's only been six days since iOS 12.3 public beta 3 was released.

Beta 4 doesn't bring too much to the beta table. According to Apple's release notes, the update solves an issue that would prevent 12.3 from installing on devices running previous versions of iOS. It's likely, however, beta 4 adds bug fixes for issues that we've seen in the last three betas, even problems that Apple doesn't address in the release notes.

The upcoming iOS 12.3 as a whole can't quite call itself feature-filled, however, it does bring Apple TV Channels to iPhone, as well as a series of bug fixes that exist in previous beta versions.
