Apple has released the fourth developer beta of iOS 27 to give developers and early testers another look at the upcoming iPhone software update before its public rollout. The latest beta brings small but useful changes across apps like Photos, Siri, Camera and Apple TV. Apple has also made a few interface tweaks and removed one feature that was introduced in the previous beta. While this update is mainly meant for developers, users who are enrolled in Apple’s Developer Program can also install it. Before installing the beta software, don’t forget to back up your iPhone, as the update may have bugs. Here is everything you need to know about the iOS 27 beta 4 update, including what’s new, how you can install it and which devices support it.
iOS 27 beta 4 adds a new Automatic Downloads option in the Apple TV settings. When enabled, the next two episodes of shows in Continue Watching will download automatically and will be removed after you watch them, reports MacRumors.
Apple has also introduced a “Zoom Photos to Fill” option in the Photos settings. It slightly enlarges photos that almost match the iPhone’s screen size. This feature is turned on by default. Furthermore, the wallpaper effect added in the Notification Center in beta 3 has now been removed.
Siri has received several updates. The voice selection page has been redesigned, and more voice options are said to arrive soon. Users can now also adjust how many lines appear in Siri previews. In Accessibility, there is a new “Always Show Request” toggle that displays a transcription of what you say to Siri. Apple has also added a splash screen when opening the Siri Search or Ask interface by swiping down.
In the Camera section of the Settings app, you will now see an option to select a ProRes log format if you toggle Apple ProRes on. You can select ProRes Log Video Encoding and choose Log or Log 2.
Other changes include per-network Connectivity Assist controls and a redesigned AirPods section in Control Center with more Adaptive mode options.
