Changes in iOS 26 Beta 4
iOS 26 Beta 4 brought notable updates from the previous beta. Adjustments were made to enhance legibility, including a slight decrease in transparent UI elements and enhancements to the Liquid Glass design. Notification summaries for News and Entertainment were re-enabled after being disabled previously.
Further changes included modifications to the Camera app icon and Call Screening features. Navigation through the Notification Centre was improved in the initial iOS 26 beta 4 by darkening the background slightly to address legibility concerns reported by early testers.
Apple is anticipated to launch iOS 26, unveiled during WWDC 2025, alongside the iPhone 17 series this year. While details of the phone launch are pending confirmation, leaked specifications are already circulating online.
