Security Evaluation

1. Device Security

Criterion	Value	Proof	Comment
Known hardware tampering	Rare	🔗 Proof	The Galaxy A37 5G is protected by the Samsung Knox security platform. Knox-compatible devices use a warranty bit to detect certain unauthorized software modifications, such as loading unofficial firmware. This provides integrity protection, but it does not measure physical hardware tampering frequency. No model-specific tampering statistics were established, so Rare is a provisional estimate.
Known vulnerabilities	Rare	🔗 Proof	Samsung regularly publishes security advisories identifying Android and Samsung-specific vulnerabilities and their fixes. These advisories demonstrate that platform vulnerabilities exist, but do not establish a high frequency of unpatched vulnerabilities specifically affecting the Galaxy A37 5G (SM-A376B). The Rare rating is provisional and should not be interpreted as an absence of vulnerabilities.
Prior attacks	None	🔗 Proof	No publicly confirmed attack specifically using the Galaxy A37 5G (SM-A376B) in an IoT botnet or similar campaign was identified in the reviewed sources. Samsung's general security advisories document vulnerabilities, not a complete history of attacks on this model. None is used provisionally and does not prove that the device has never been attacked.
Updatability	Rare	🔗 Proof	Samsung officially lists the Galaxy A37 5G among devices receiving quarterly security updates. Samsung also promises up to six generations of operating system upgrades and six years of security support, while model SM-A376B has multiple documented firmware updates in 2026. Since the official maintenance category is quarterly rather than monthly, Rare is selected for update frequency under the Wiki-IoT rubric.
Category Score	Score: 2 / 3

2. System Security

Criterion	Value	Proof	Comment
Authentication with other systems	Partial	🔗 Proof	Samsung Account provides password-based sign-in and two-step verification for supported account operations. The phone also supports secured app and service authentication. However, the authentication methods of connected third-party services and accessories vary, and mutual authentication has not been established for every connection. Partial authentication is therefore selected.
Communications	Encrypted with up-to-date encryption	🔗 Proof	Android supports modern TLS-protected network communication. For applications targeting Android 9 or later, cleartext network traffic is disabled by default unless explicitly permitted. This provides a modern encrypted communication framework on the Galaxy A37 5G, although individual applications can configure exceptions and not every network connection is guaranteed to be encrypted.
Storage	Encrypted with up-to-date encryption	🔗 Proof	Samsung Knox devices use Android file-based encryption to protect stored data. Credential-encrypted and device-encrypted storage employ cryptographic keys linked to user credentials and hardware-backed security mechanisms. The Galaxy A37 5G runs Android 16 and supports the Knox security platform, providing modern encryption of internal user data.
Category Score	Score: 2 / 3

3. User Authentication

Criterion	Value	Proof	Comment
Account management	Basic	🔗 Proof	The Galaxy A37 5G allows users to add, manage, and remove Samsung, Google, and other supported service accounts. Users can modify account information and security settings. However, ordinary Galaxy smartphones do not provide a full general-purpose local multi-user login system with independently assigned privilege levels, so Basic is selected.
Authentication	Secure	🔗 Proof	The Galaxy A37 5G supports screen-lock PINs, passwords, patterns, and fingerprint authentication. Samsung Knox provides additional protection for sensitive credentials, while optional facial unlocking offers another convenient method. Because facial recognition and weak user-selected credentials have limitations, a strong PIN or password is recommended.
Brute-force protection	Exist	🔗 Proof	Android uses authentication rate-limiting mechanisms to restrict repeated incorrect screen-lock PIN, pattern, and password attempts. Trusted execution or secure hardware can enforce increasing delays after failed guesses. The Galaxy A37 5G uses the Android security architecture, although its exact device-specific lockout thresholds have not been independently tested.
Event logging	Partial logging	🔗 Proof	Samsung's Privacy Dashboard provides records of selected application access to sensitive permissions, including camera, microphone, and location. The device also provides security and privacy controls. However, these records do not amount to a complete audit log of every device unlock, authentication failure, or system access event. Partial logging is selected.
Passwords	Require change after setup	🔗 Proof	Samsung Galaxy devices allow users to create their own screen-lock PINs, passwords, or patterns during setup and change them later. A shared factory-default screen-lock password is not documented. However, the phone does not require changing an existing default password after setup. The selected Wiki-IoT category is an approximate match because the rubric does not provide a separate option for user-created credentials.

The Samsung Galaxy A37 5G (SM-A376B) is a mid-range smartphone introduced by Samsung Electronics in March 2026 and released in selected markets in April 2026. The evaluated UK configuration features the Samsung Exynos 1480 processor, Xclipse 530 GPU, 8GB of RAM, 256GB of internal storage, and a 6.7-inch FHD+ Super AMOLED display with a refresh rate of up to 120Hz.

The device features a 5000mAh battery with 45W Super Fast Charging 2.0, a triple rear camera system consisting of a 50MP main camera, an 8MP ultra-wide camera and a 5MP macro camera, and a 12MP front camera. It supports 5G connectivity, Wi-Fi 6, Bluetooth 5.3, NFC, GPS and USB Type-C connectivity. The device is rated IP68 for water and dust resistance.

The Galaxy A37 5G was originally released with Android 16 and Samsung One UI 8.5. Samsung provides up to six generations of operating system upgrades and six years of security updates, with security maintenance support scheduled through March 2032. The model is included in Samsung's quarterly security update program, and official firmware records document several updates during 2026.

The smartphone incorporates multiple security features, including Samsung Knox, Knox Vault, file-based data encryption, fingerprint authentication, screen-lock passwords, authentication rate limiting, and security and privacy controls. Samsung's Auto Blocker provides additional protection against unauthorized application installation and certain potentially harmful USB operations.

The Android platform supports modern TLS-based network encryption and restricts cleartext network communication by default for supported applications. However, individual applications may configure exceptions, so encrypted communication cannot be guaranteed for every connection.

Samsung publishes security advisories addressing Android and Samsung-specific vulnerabilities. The existence of such advisories demonstrates that software security risks remain relevant even on devices receiving regular updates. The reviewed public evidence does not establish the frequency of successful attacks or malicious physical hardware tampering specifically involving the Galaxy A37 5G (SM-A376B).

This classification is based on publicly available Samsung documentation, Android security documentation and security advisories reviewed as of October 23, 2026. Some ratings remain provisional because device-specific attack statistics, physical tampering frequency data and independent penetration testing results are limited.

The resulting Wiki-IoT security grade is an evidence-based preliminary assessment and does not represent an official Samsung security certification or a guarantee that the device is free from vulnerabilities.
