Android devices are packed with features that go beyond the standard user interface. One of these lesser-known features is the IoT Hidden Menu android —a secret diagnostic and configuration tool used primarily by developers and technicians to test hardware functions and gather system information.
What Is the IoT Hidden Menu?
The IoT Hidden Menu is a special settings panel embedded in many Android devices, particularly from manufacturers like Samsung, LG, and Motorola. "IoT" in this context typically stands for Internet of Things, but in Android's hidden menu, it refers more broadly to system-level testing tools for sensors, connectivity, and input/output components.
This menu gives users access to advanced diagnostics, including:
Sensor testing (accelerometer, gyroscope, proximity sensor, etc.)
- Touch screen and display calibration
- Vibration and speaker tests
- Wi-Fi, Bluetooth, and network diagnostics
- Hardware button functionality
- Battery status and charging tests
It's not designed for regular users but is a powerful tool for developers, support technicians, or power users trying to troubleshoot hardware issues.
How to Access the IoT Hidden Menu
The IoT Hidden Menu is not available on all devices, and access methods may vary depending on the manufacturer. The most common way to open this menu is via dialer codes—special codes entered in the phone app that unlock hidden settings.
Here’s how you can try accessing it:
Open the Phone app.
- Dial the secret code:
- The most common code is: #0#
- This typically works on Samsung devices .
If the code works, the IoT Hidden Menu will open immediately without confirmation.
Navigate through various diagnostic options and tests from the menu.
Note: On some devices or newer Android versions, these codes may be disabled or require developer settings to be enabled. Some carriers also restrict access.
Important Warnings
Use with caution: The hidden menu can change hardware settings or activate diagnostic modes that may interfere with normal operation.
No undo button: There’s often no confirmation or “undo” option after performing a test.
Warranty concerns: Altering hidden system settings could potentially affect your warranty if misused.
Device-specific: Not all Android phones support this menu. Pixel phones, for example, may not include it at all.
Final Thoughts
The IoT Hidden Menu is a fascinating look into the deeper layers of Android. While it’s not built for everyday users, it can be extremely helpful when diagnosing hardware problems or running quick performance tests. Just make sure you proceed with caution and understand the implications of using advanced system tools.
