Comment
|
| Known hardware tampering
|
Rare
|
🔗 Proof
|
Android Verified Boot provides an integrity-verification framework for boot and system partitions, helping to detect unauthorized modifications to system software. However, software integrity protection is different from resistance to physical hardware tampering. No model-specific statistics on malicious hardware modification of the realme 16 Pro 5G (RMX5120) were found. Rare is a provisional estimate and is not directly demonstrated by the cited source.
|
| Known vulnerabilities
|
Rare
|
🔗 Proof
|
The October 2026 Android Security Bulletin documents vulnerabilities affecting Android components. The realme 16 Pro 5G uses Android 16, making platform security advisories relevant. However, the bulletin does not establish which specific vulnerabilities remain unpatched on RMX5120. Rare is a provisional assessment rather than a verified model-specific vulnerability frequency.
|
| Prior attacks
|
None
|
🔗 Proof
|
The reviewed public manufacturer security information did not establish a confirmed botnet attack or successful exploitation incident specifically targeting the realme 16 Pro 5G (RMX5120). The manufacturer's security page is not a comprehensive attack database. None is therefore a provisional classification, not evidence that this model has never been attacked.
|
| Updatability
|
Rare
|
🔗 Proof
|
realme provides over-the-air system and security updates. Its published security-support policy lists the realme 16 Pro series with support extending into 2032, while public RMX5120 firmware reports document security patches during 2026. However, the available evidence does not establish consistent monthly delivery, and an update was reported as delayed in September. Rare is selected conservatively for observed update frequency rather than the length of the support commitment.

|
| Authentication with other systems
|
Partial
|
🔗 Proof
|
The Android-based device can access Google Account services protected by two-step verification and passkeys. realme UI also provides local authentication and privacy controls. However, the authentication policies used by third-party apps, wireless accessories, and remote services vary, and universal mutual authentication has not been demonstrated. Partial authentication is therefore selected.
|
| Communications
|
Encrypted with up-to-date encryption
|
🔗 Proof
|
Android 16 supports modern encrypted network connections through TLS and HTTPS. Android's Network Security Configuration disables cleartext network traffic by default for applications targeting Android 9 or later unless an exception is configured. These platform protections are available on the realme 16 Pro 5G, although not every third-party network connection is guaranteed to be encrypted.
|
| Storage
|
Encrypted with up-to-date encryption
|
🔗 Proof
|
The realme 16 Pro 5G was launched with Android 16. Devices launched with Android 10 or later are required to implement file-based encryption to protect stored user data with cryptographic keys. realme UI also provides privacy-password protection for sensitive app data. This rating is based on Android platform requirements rather than an independent audit of the RMX5120 storage implementation.

Comment
|
| Account management
|
Basic
|
🔗 Proof
|
realme UI 7.0 provides System Cloner, which creates a separate environment with its own password or fingerprint and isolated application data. The main environment can manage and remove this clone. The phone also supports management of connected service accounts. However, System Cloner is not equivalent to a fully verified local multi-user account system with independent privilege levels. Basic is selected conservatively.
|
| Authentication
|
Secure
|
🔗 Proof
|
The realme 16 Pro 5G supports an in-display optical fingerprint sensor, facial recognition, and screen-lock credentials. realme's official instructions require a screen-lock password before fingerprint registration. App Lock and Privacy Password provide additional access controls for sensitive applications. These features support multiple authentication methods, although the security strength of face unlock has not been independently established.
|
| Brute-force protection
|
Exist
|
🔗 Proof
|
Android uses rate-limiting mechanisms to protect PINs, patterns, passwords, and authentication-bound cryptographic keys against repeated guessing. Such controls make automated brute-force attacks more difficult. The exact lockout intervals and hardware-backed implementation on the realme 16 Pro 5G have not been independently measured.
|
| Event logging
|
Partial logging
|
🔗 Proof
|
Android provides a Privacy Dashboard that records selected application permission access events, such as access to the camera, microphone, and location. realme UI also provides privacy-related controls. However, the available documentation does not confirm a complete audit log of every device unlock, failed authentication attempt, or account login on RMX5120. Partial logging is selected.
|
| Passwords
|
Require change after setup
|
🔗 Proof
|
realme UI supports user-created privacy passwords, including numeric, pattern, and alphanumeric options. Password recovery can involve security questions, a recovery email, or a linked account. No shared factory-default screen-lock password has been documented for RMX5120. The Wiki-IoT option Require change after setup is only an approximate match because a mandatory change of a preinstalled password has not been established.
