Security Evaluation

Criterion	Value	Proof	Comment
Known hardware tampering	None	🔗 Proof	The brand follows a transparent design concept, with no known cases of hardware-level malicious tampering. iFixit's teardown report also did not find any abnormalities.
Known vulnerabilities	Rare	🔗 Proof	Promises regular security updates, and as a relatively niche brand, it is less targeted by large-scale attacks. Identified critical vulnerabilities are patched through monthly security updates.
Prior attacks	None	🔗 Proof	As of now, there have been no publicly reported large-scale successful attacks specifically targeting the Phone (2a).
Updatability	Very common	🔗 Proof	The official promise to provide 3 major Android version updates and 4 years of security updates makes the update strategy very clear and common for mid-range devices.
Category Score	Score: 2 / 3

Criterion	Value	Proof	Comment
Authentication with other systems	Full	🔗 Proof	As an Android device, it fully supports authentication integration with Google services (such as Google accounts) and other systems through standard APIs (such as OAuth).
Communications	Encrypted with up-to-date encryption	🔗 Proof	The system defaults to enforcing the use of TLS and other encryption protocols for network communication, in line with modern Android standards.
Storage	Encrypted with up-to-date encryption	🔗 Proof	Devices are shipped with file-level encryption (FBE) or full-disk encryption (FDE) enabled by default to protect user data.
Category Score	Score: 1 / 3

Criterion	Value	Proof	Comment
Account management	Full	🔗 Proof	Supports a complete Google account management system, including adding, deleting accounts, and synchronization management.
Authentication	Secure	🔗 Proof	It provides both under-display optical fingerprint recognition and facial recognition for biometric authentication, offering higher security than using passwords alone.
Brute-force protection	Exist	🔗 Proof	After multiple consecutive failed attempts of fingerprint or password, the system will enforce a delay or require the use of the master password to unlock, preventing brute-force attacks.
Event logging	Access event logged	🔗 Proof	System-level events such as login successes/failures are recorded, but ordinary users cannot directly view the complete logs.
Passwords	Require change after setup with complexity requirements	🔗 Proof	When setting up or changing the screen lock for the first time, the system requires a password/PIN/pattern that meets minimum length and complexity requirements, and prompts for periodic changes.
