iOS 27 adds Connectivity Assist, paste suggestions, and separate ring alarm volumes

iOS 27 introduces Connectivity Assist to switch to cellular data on weak Wi-Fi, found in Settings under Wi-Fi. Copy-paste now shows a suggestion above text fields for faster access. Ringtone and alarm volumes can be set independently in Settings under Sounds & Haptics by disabling Match Ringtone Volume. These features improve daily usability without major interface changes.
