What diagnostic tools are available in the IoT hidden menu?
Android smartphones often include hidden menus designed for testing and diagnostic purposes. One such feature is the IoT Hidden Menu, which provides technical information and tools related to the devices hardware components and connectivity. Though not commonly used by regular users, this menuknown as the IoT hidden menu Androidis valuable for developers, technicians, and advanced users who want to check device functions or troubleshoot problems.
What Is the IoT Hidden Menu?
The IoT Hidden Menu is a diagnostic interface found on some Android devicesusually accessible through secret dialer codes or device-specific methods. "IoT" in this context stands for "Internet of Things," referring to the interconnected features of modern devices, though the menu primarily focuses on internal diagnostics rather than smart home integrations. It allows access to a variety of tests and readouts that aren't available in the standard settings.
Diagnostic Tools Available in the IoT Hidden Menu
1. Display Test
This tool checks the screens ability to display colors, brightness levels, dead pixels, and overall screen uniformity. It helps identify any display-related issues, such as color bleeding or non-functional pixels.
2. Touch Screen Test
Users can assess the touch sensitivity and accuracy across the display. This is useful for detecting unresponsive areas or erratic touch behavior, which can result from screen damage or calibration issues.
3. Sensor Readouts
The IoT hidden menu can display real-time data from the devices internal sensors, including the accelerometer, gyroscope, proximity sensor, magnetometer, and light sensor. This helps confirm whether a sensor is working correctly and delivering accurate data.
4. Vibration Test
This function tests the vibration motor, allowing users to confirm that the device can vibrate at different intensities. It's useful for identifying hardware issues with haptic feedback or silent alerts.
5. Camera Test
Users can activate the front and rear cameras independently to test image clarity, focus functionality, and camera responsiveness. This is helpful for troubleshooting camera issues or verifying camera hardware.
6. Audio and Speaker Test
This tool checks the functionality of the earpiece, main speaker, and microphone. It may also test volume levels, stereo balance, and playback clarity. These tests can help detect audio distortion or faulty speaker output.
7. Connectivity Diagnostics
The menu can offer basic checks for Wi-Fi, Bluetooth, and mobile network functionality. Some devices also display signal strength levels or show advanced modem information, making it easier to pinpoint network issues.
8. Button Function Test
The physical buttons of the device, such as the power key, volume buttons, and home or back buttons, can be tested for responsiveness. This is especially useful after hardware repair or to confirm button failures.
9. Battery Status and Temperature
Battery-related data, including temperature, charge level, voltage, and health status, may also be visible. Monitoring this information helps identify overheating or battery degradation.
10. Software and Firmware Information
Some versions of the IoT hidden menu show software build versions, baseband details, and firmware versions. This information is useful when troubleshooting compatibility issues or verifying software integrity.
Access and Caution
Not all Android devices have an IoT hidden menu, and its availability depends on the manufacturer and software version. Accessing the menu usually involves entering a special code in the dialer (such as ##4636##) or navigating through system settings on rooted or developer-mode-enabled devices.
While the tools inside the menu are designed for diagnostics, making changes without understanding their effects can lead to undesired behavior. It's recommended to use the IoT hidden menu for observation and testing, not for altering settings unless guided by technical support.
Conclusion
The IoT hidden menu on Android offers a range of diagnostic tools that allow users to test screen performance, sensors, audio, camera, connectivity, and more. Although primarily intended for advanced users and technicians, this menu can be incredibly useful for troubleshooting hardware or confirming proper device functionality. When used carefully, it provides insights that can help extend the life of your device or pinpoint issues before they become serious.
