|---|---|---|---|
| Criterion | Value | Proof(s) | Comment |
| Known hardware tampering | Rare | [2] | As a legitimate brand device, widespread hardware backdoors are uncommon. However, risks in the low-end supply chain cannot be entirely ruled out. |
| Known vulnerabilities | Rare | [3] | Runs an old Android version with no ongoing security patches, leaving it exposed to numerous publicly known vulnerabilities. |
| Prior attacks | Rare | [4] | No widely reported targeted attacks, but the high vulnerability count makes it susceptible to generic malware. |
| Updatability | Rare | [5] | Official support for both OS upgrades and security patches has been discontinued. |

| System | |||
|---|---|---|---|
| Criterion | Value | Proof(s) | Comment |
| Authentication with other systems | Partial | [6] | Supports basic screen lock methods (pattern, PIN, password). Unlikely to have a Trusted Execution Environment (TEE) for enhanced security. |
| Communications | Encrypted with obselete encryption | [7] | Relies on basic knowledge factors (PIN/pattern). Lacks more secure factors like a fingerprint sensor or facial recognition. |
| Storage | Encrypted with obselete encryption | [8] | Likely uses legacy Full-Disk Encryption (FDE) which is considered less secure than modern File-Based Encryption (FBE). The encryption strength may be outdated. |

| User Authentication | |||
|---|---|---|---|
| Criterion | Value | Proof(s) | Comment |
| Account management | Basic | [9] | Supports basic screen lock methods (pattern, PIN, password). Unlikely to have a Trusted Execution Environment (TEE) for enhanced security. |
| Authentication | Basic | [10] | Relies on basic knowledge factors (PIN/pattern). Lacks more secure factors like a fingerprint sensor or facial recognition. |
| Brute-force protection | Basic | [11] | Includes fundamental protections like timed delays after repeated failed unlock attempts. |
| Event logging | Partial logging | [12] | The system has basic logging capabilities, but these are not accessible to users and unlikely to detail security-specific events. |
| Passwords | Require change after setup | [13] | No evidence of forced password change or complexity requirements upon first use. Security relies heavily on user awareness. |
