Android
1. Default App Settings
- Pre-selected Google services and apps as defaults
 - Making it multi-step process to change default apps
 - Prompting users to switch back to Google apps when using alternatives
 
2. Privacy Controls
- Spreading privacy settings across multiple menus and submenus
 - Using confusing terminology for privacy options
 - Making privacy-protective options require more steps than data-sharing ones
 - Presenting data collection as necessary for "improved services"
 
3. Google Account Integration
- Repeatedly prompting for Google account sign-in
 - Making certain features unavailable without Google account
 - Suggesting that device functionality will be limited without Google services
 - Making it unclear which features require Google services versus Android core features
 
4. App Store Manipulation
- Promoting Google Play Store apps over third-party app stores
 - Making installation from alternative sources require multiple security confirmations
 - Using security warnings that may overly discourage third-party app installations
 - Making it complex to use alternative app stores
 
5. Location Services
- Persistent prompts to enable location services
 - Bundling useful features with location tracking
 - Making it difficult to understand which apps use location in background
 - Using vague language about location data collection purposes
 
6. Notification Management
- Making notifications opt-out rather than opt-in
 - Requiring individual management for each app's notifications
 - Using persuasive messaging to keep notifications enabled
 - Making bulk notification management less accessible
 
7. Data Backup and Sync
- Presenting Google backup as the only reliable backup solution
 - Making it unclear what data is being backed up and when
 - Using fear of data loss to encourage cloud backup enrollment
 - Making local backup options less prominent
 
8. Update System
- Making system updates difficult to defer
 - Using persistent notifications for updates
 - Bundling privacy policy changes with feature updates
 - Making it hard to understand what changes updates bring
 
9. AI and Assistant Features
- Making AI features opt-out rather than opt-in
 - Presenting AI features as essential for normal operation
 - Bundling useful features with increased data collection
 - Using unclear language about AI data usage
 
10. App Permissions
- Making permission management complex
 - Using vague descriptions for permission requirements
 - Making it difficult to revoke permissions after granting
 - Bundling necessary and unnecessary permissions together
 
11. Device Setup
- Fast-track setup that skips privacy options
 - Making custom setup more time-consuming
 - Pre-selecting data-sharing options during setup
 - Using "recommended" settings that favor Google services
 
12. Performance Optimization
- Suggesting that third-party apps impact performance more than Google apps
 - Making battery optimization more aggressive for non-Google apps
 - Using battery warnings to discourage certain app usage
 - Making custom optimization difficult
 
The impact of these patterns is particularly significant because Android is a dominant mobile operating system globally. These designs can:
- Create dependency on Google services
 - Make privacy-conscious choices more difficult
 - Limit user awareness of alternatives
 - Increase the complexity of maintaining privacy
 - Lead to unintended data sharing
 - Create friction when trying to use non-Google services
