Apple has just released a bunch of updates over the past few days. Today, we get the fourth public beta of iOS 13 and iPadOS 13 as well as the fifth developer beta of watchOS 6 and the fourth beta of tvOS 13. These come after the developer beta five of iOS 13 was released yesterday. For the public beta of iOS 13 and iPadOS 13, you can get the update via the Settings app on your device. It’s rolling out now and should come to most users running the public beta soon.
The notable changes that came with the fifth developer beta of iOS 13 and iPadOS 13 include being able to adjust the Home screen icon density. This means you can choose between having a 4 x 5 grid of apps or a 6 x 5 grid of apps. Other changes in beta 5 include new wallpapers in the Home app and a redesigned share sheet that now groups actions by apps.
