Visual Interface: Liquid Glass
Adjust Tint/Opacity: Navigate to Settings > Appearance > Liquid Glass and use the slider to adjust contrast.
Reduce Transparency: Navigate to Settings > Accessibility > Display & Text Size and toggle on Reduce Transparency. Note: This global setting overrides individual Liquid Glass controls.
Managing Siri and Writing Tools
How to Limit Siri History: Go to Settings > Siri > Keep Conversations and select 30 Days or 1 Year. Tap Opens To and select A New Conversation to ensure Siri launches with a blank screen.
How to Disable AI Writing Assistance: Navigate to Settings > Screen Time > Content & Privacy Restrictions. Enable restrictions, then go to Siri > Writing Assistance > Don't Allow.
Fine-Tuning Voice and Video Behavior
How to revert to "Hey Siri": To prevent accidental triggers, navigate to Settings > Siri > Talk to Siri and revert the preference from "Siri" to "Hey Siri".
How to turn off automatic subtitles: Navigate to Settings > Accessibility > Subtitles & Captioning. Disable When Languages Don't Match, Show When Muted, or Show on Skip Back as needed.
Editorial Analysis
Apple has increasingly positioned Apple Intelligence as a core system experience, making customization an important balance between automation and user control. Some users may appreciate the proactive assistance, while others may prefer a more manual, traditional interface. Whether these features become "annoying" or "essential" will likely depend on how Apple refines the interface before the final release. These changes reflect a broader shift from static OS settings toward adaptive AI-driven interfaces.
Known Beta Caveats
Feature Variability: Menu names, feature locations, and UI layouts are subject to change.
Hardware/Regional Limits: Apple Intelligence functionality depends on supported Apple Intelligence hardware and is subject to language and regional rollouts.
Stability: Current beta performance is not representative of the final commercial version.
Frequently Asked Questions
Can I uninstall the beta? Yes, but it requires a clean install and typically necessitates a valid backup made before installing the beta version.
How do I leave the iOS Beta Program? Go to Settings > General > Software Update > Beta Updates, then set it to "Off."
Will these settings change after the stable release? Apple has not confirmed that current menu names or settings paths will remain unchanged for the final public release.
