Apple Says iOS 27 Fixes iPhone Wi-Fi-to-Cellular Lag

Summary
iOS 27 sharpens how iPhones switch between Wi-Fi and cellular, aiming to eliminate the brief no-data gap users often hit when leaving a Wi-Fi network.
Apple framed the change as part of broader platform improvements focused on making the software more responsive, reliable and faster in everyday use.
The lag has historically forced some users to manually disable Wi-Fi in Control Center to trigger cellular service; Apple says that workaround should no longer be necessary.
After 2 months on the beta, the report's tester said the iPhone maintained a solid connection during network transitions, though wider user results will depend on the public release.
