| Operating System | Android version support | Support the Android versions officially stated by the watch operating system and companion application. | Android compatibility is not universal; Wear OS watch and companion-app requirements vary by Wear OS generation and manufacturer implementation. | Request a published compatibility matrix and test results for current Android releases. |
| Operating System | Wear OS support | For Wear OS products, provide access to Google Play services and the Google Play Store where officially supported in the target market. | Wear OS is Google's smartwatch operating system. Available applications and services can differ by watch model, operating-system version, country, and account configuration. | Verify the exact Wear OS version, update policy, regional availability, and required Google services. |
| Operating System | Non-Wear OS support | For proprietary operating systems, provide an Android companion application with documented minimum Android requirements and supported devices. | Proprietary systems commonly depend on a mobile application for setup, synchronization, notifications, health data, firmware updates, and account management. | Check installation, pairing, synchronization, and update performance on representative Android phones. |
| Wireless Connectivity | Bluetooth Low Energy | Bluetooth Low Energy should be used for routine watch-to-phone communication to reduce power consumption. | Bluetooth Low Energy uses the Generic Attribute Profile (GATT) for structured data exchange between compatible devices. | Confirm supported Bluetooth version, profiles, range, reconnection behavior, and coexistence performance. |
| Wireless Connectivity | Bluetooth version | Bluetooth 5.0 or later is a practical baseline for a new Android smartwatch supply program. | Bluetooth 5.x can provide improvements in range, throughput options, and power-management features compared with earlier Bluetooth generations; actual performance depends on implementation. | Obtain the Bluetooth qualification identifier and verify the exact radio configuration. |
| Wireless Connectivity | Phone-call capability | If calling is required, support the relevant Bluetooth Hands-Free Profile or an officially documented cellular implementation. | Bluetooth calling generally requires a paired phone, microphone, speaker, and compatible phone operating-system behavior. Cellular models require additional network and carrier support. | Test incoming calls, outgoing calls, contacts, microphone quality, and reconnection after signal loss. |
| Mobile Application | Companion-app distribution | Provide a stable Android application through an official distribution channel, with clear version history and permissions disclosure. | The application should support account creation, device pairing, notification settings, health-data synchronization, firmware updates, and data export where available. | Review application ratings, release frequency, privacy disclosures, and support response procedures. |
| Mobile Application | Android notifications | Support configurable notifications for calls, messages, calendar events, and selected third-party applications. | Notification behavior depends on Android permissions, battery-optimization settings, background execution limits, and the companion application's implementation. | Test notifications under locked-screen, low-battery, background, and interrupted-Bluetooth conditions. |
| Health Features | Health-data handling | Clearly identify which measurements are wellness features and which, if any, are regulated medical functions. | Heart rate, blood oxygen saturation, sleep, menstrual-cycle, and activity features can be affected by fit, skin contact, motion, physiology, and software algorithms. | Require measurement limitations, validation documentation, and regulatory statements before making medical claims. |
| Data Security | Data in transit | Use authenticated and encrypted communication between the watch, Android application, and cloud services. | HTTPS using current TLS configurations is a common baseline for cloud communication; Bluetooth pairing should use the strongest security mode supported by the devices. | Request a security architecture, encryption details, certificate-management process, and penetration-test summary. |
| Data Security | Data at rest | Protect stored health, account, and authentication data on the watch, phone, and backend systems using access controls and encryption where appropriate. | Protection should include secure credential storage, least-privilege access, protected backups, and restricted administrative access. | Review storage locations, retention periods, deletion procedures, and access-control evidence. |
| Data Security | Privacy and consent | Provide a clear privacy policy covering data collection, purpose, sharing, retention, international transfers, and user deletion requests. | Health and personal data should be collected with appropriate consent and processed according to applicable privacy laws in the target sales markets. | Confirm privacy-policy language, consent screens, account deletion workflow, and data-export capability. |
| Firmware and Support | Secure firmware updates | Support authenticated firmware packages, protected update delivery, rollback safeguards, and documented update procedures. | Firmware updates should be digitally verified before installation and should not expose the device to unauthenticated update packages. | Ask for the update-signing process, update frequency, end-of-support policy, and failure-recovery method. |
| Firmware and Support | Vulnerability response | Maintain a documented process for receiving, assessing, and remediating security vulnerabilities. | A mature process includes a security contact, severity assessment, remediation targets, release notes, and customer notification procedures. | Request vulnerability-disclosure documentation and recent security-update records. |
| Quality Assurance | Android interoperability testing | Test across multiple Android versions, screen sizes, chipsets, manufacturers, and power-management configurations. | Compatibility should cover pairing, synchronization, notifications, calls, GPS-assisted functions, health-data transfer, and firmware updates. | Require a test report with device models, Android versions, test cases, pass rates, and unresolved issues. |
| Supply Reliability | Documentation and traceability | Provide product specifications, software-version records, component traceability, warranty terms, and a defined after-sales process. | Complete documentation reduces compatibility, compliance, maintenance, and product-recall risks during long-term supply. | Prefer suppliers able to provide revision-controlled technical and compliance documentation. |
