The most common Motorola engineering mode code is *#*#4636#*#*, which opens a hidden Android testing menu to view detailed phone, battery, and network information. These codes are powerful tools for diagnostics and troubleshooting, but they should be used with extreme caution.
If you’re a tech-savvy user looking to access the hidden diagnostic and hardware testing menus on your Motorola smartphone, this guide will provide you with the most useful codes and explain what they do.
CRITICAL WARNING: Before You Enter Any Code
These hidden menus can access advanced, sensitive settings on your device. It is crucial that you understand the risks before proceeding.
- Do not change any settings you do not fully understand. Modifying network bands, radio settings, or other parameters can cause your phone to lose cellular connectivity, disable data, or stop working correctly.
- Changing settings may require a factory reset to fix. A factory reset will erase all of your personal data, including photos, contacts, and apps.
- You proceed at your own risk. These menus are intended for developers and technicians.
For most users, these menus should only be used to view information, not to change it.
The Main Motorola Engineering & Testing Codes
To use these codes, open your phone’s dialer app and enter the sequence exactly as shown. The menu should appear automatically after the last character is entered.
The Android Testing Menu (*#*#4636#*#*)
This is a standard Android code that works on most Motorola phones. It provides a wealth of information about your device’s status and connectivity. The menu typically includes:
- Phone Information: Here you can see your IMEI number, current network, signal strength (RSSI/RSRP), and whether VoLTE is provisioned. Warning: This menu also allows you to change your “Preferred Network Type.” Do not change this setting unless you are an expert, as selecting the wrong option can cut off your mobile data and call service.
- Battery Information: This screen shows your battery’s health, current charge level, temperature, and voltage. It’s a useful tool for diagnosing battery problems.
- Usage Statistics: This provides a detailed log of which apps you have used and for how long since the last restart.
- Wi-Fi Information: Here you can find detailed data about your Wi-Fi connection, including the IP address, MAC address, and link speed.
The Motorola CQATest Menu (*#*#2486#*#*)
This code launches a Motorola-specific hardware diagnostic tool called CQATest (Certified Quality Auditor Test). This menu is designed to let you test the physical components of your phone to ensure they are working correctly.
Inside the CQATest menu, you can run diagnostics on:
- Touchscreen sensitivity and accuracy
- Display colors and dead pixels
- Speakers and microphones
- Front and rear cameras
- Sensors (accelerometer, gyroscope, proximity sensor)
- Vibration motor
- And much more.
This is a very safe menu to explore as it’s designed for testing and doesn’t allow you to change critical system settings.
Other Useful Dialer Codes for Your Motorola Phone
These are safe, universal codes that provide quick information on any Motorola device.
| Code | Purpose & Explanation |
| *#06# | Check your IMEI: This instantly displays your phone’s unique 15-digit IMEI (International Mobile Equipment Identity) number. |
| *#07# | Check your SAR value: This shows the Specific Absorption Rate (SAR) information for your device, which is a measure of radio frequency energy absorbed by the body. |
Frequently Asked Questions
Why doesn’t the engineering mode code work on my Motorola phone?
This can happen for a few reasons. Some mobile carriers (like Verizon or AT&T) customize the phone’s software and may disable certain diagnostic codes. Additionally, codes can vary based on the phone’s specific model, chipset (e.g., Qualcomm vs. MediaTek), or Android version.
Can I use these codes to SIM-unlock my phone?
No. Engineering mode codes are for diagnostics only and cannot be used to SIM-unlock your phone from a carrier. Carrier unlocking is a separate process that must be handled by your mobile provider once you meet their eligibility requirements.
I changed a setting and now my phone has no signal. What do I do?
This is the primary risk of using these menus. First, try restarting the phone. If that doesn’t work, go to your main Settings > System > Reset options and try “Reset Wi-Fi, mobile & Bluetooth.” As a last resort, you may need to perform a factory reset, which will erase all your data.
What is “CQATest”?
CQA stands for Certified Quality Auditor. The CQATest app is a hidden diagnostic tool used by Motorola technicians during manufacturing and repair to quickly verify that all of the phone’s hardware components are functioning correctly.
Conclusion
Motorola engineering mode codes like *#*#4636#*#* for system info and *#*#2486#*#* for hardware tests are powerful diagnostic tools. They are excellent for viewing detailed information about your phone and checking if your hardware is working properly. However, you should never change a setting in these hidden menus unless you are an expert, as doing so can cause serious connectivity issues or other problems with your device.
