  • Compatibility layers: Improved backward compatibility for WearOS 4 apps during transition period
  • Development tools: Better debugging and testing capabilities for app developers

What's Removed or Changed from WearOS 4​

Deprecated Features

  • Legacy Complications: Some older watch face complications no longer supported, requiring updates
  • Notification Actions: Certain custom notification actions removed for security and battery optimization
  • Sideloading Freedom: More restrictions on installing apps from unknown sources
  • Custom ROMs: Enhanced security makes custom firmware installation significantly more difficult

Modified Functionality

  • Always-On Display: New AOD system is more efficient but some users prefer the WearOS 4 implementation
  • Tile System: Updated tiles with new functionality but different organization than WearOS 4
  • Voice Commands: Some legacy voice commands changed or removed in favor of more natural language processing
  • Gesture Controls: Updated gesture system may require relearning muscle memory from WearOS 4

Should You Upgrade to WearOS 5?​

Upgrade Recommended If:

  • You prioritize battery life improvements and AI health features
  • You use your watch primarily within Google ecosystem (Android phone, Google services)
  • You want the latest security features and ongoing software support
  • You're comfortable with a brief adjustment period for new UI patterns

Consider Waiting If:

  • You rely heavily on specific apps that aren't yet WearOS 5 compatible
  • You prefer the WearOS 4 interface and don't want to relearn navigation
  • You use many sideloaded apps that may not work properly in WearOS 5
  • Your current WearOS 4 setup meets all your needs without issues

I observe that WearOS 5 represents Google's vision of a more intelligent, efficient smartwatch platform, but the transition requires users to adapt to new patterns while some third-party apps catch up with compatibility updates.
