For Xiaomi devices, there are several secret codes you can use to access network and signal information, similar to other Android devices. These codes can be entered in the dialer app to bring up various menus for testing and diagnostics.
1. Check Network Information and Signal Strength
- Use this code to access the Field Test Mode or engineering menu where you can view detailed network information:
This will open a menu with options like:
- Phone Information: Shows real-time network info, signal strength in dBm, network type (4G, 5G, etc.), cell tower info, and more.
- Battery Information: Details about battery status and usage.
- Wi-Fi Information: Displays info related to the current Wi-Fi connection.
- Usage Statistics: Tracks app usage and other performance data.
2. Engineering Mode for Advanced Network Settings
- To access the Engineering Mode for advanced network diagnostics and settings:
This code opens Xiaomi’s internal Hardware Test Menu, where you can view detailed diagnostics and test network components such as LTE, 5G, and Wi-Fi. It’s typically used by technicians for in-depth troubleshooting.
3. Check Signal Strength in dBm
- To quickly check your signal strength in a more detailed numerical format (dBm):
This will display your current signal strength, which is a more accurate measure than the signal bars.
4. Check Network Lock Status
- To see whether your Xiaomi device is network-locked or unlocked:
This will show the network lock status and whether your phone is restricted to a specific carrier.
5. Network Mode Switching
- IF you want to manually switch between different network modes (e.g., forcing 2G, 3G, 4G, or 5G):
From here, under the “Phone Information” section, you can manually select the network type, such as GSM, WCDMA (3G), LTE (4G), or NR (5G), depending on your location and network availability.
6. Wi-Fi Status and Information
- For detailed information about your Wi-Fi network, such as signal strength, speed, and more:
This will show the Wi-Fi MAC address and details about the connected Wi-Fi network.
7. Data Usage Statistics
- To quickly check your mobile data usage statistics:
This code will display detailed data usage information on your Xiaomi device, including mobile and Wi-Fi data consumption.
8. IMEI Number and Network Info
- To display the IMEI number and basic network information:
This code will show the IMEI (International Mobile Equipment Identity), which is unique to your device and important for network identification.
These codes provide an easy way to view and test various network aspects on Xiaomi devices. Keep in mind that some features may depend on your device model, Android version, and carrier-specific firmware.
