The Moto G Stylus 5G (including the 2022, 2024, and 2025 models) contains a secret, hidden menu—often referred to as the Testing Mode or Service Menu—that allows users to view detailed diagnostics and advanced hardware information not available in the standard Android settings.
This hidden menu is accessed by entering a specific sequence of characters, known as a secret code, directly into the phone’s dialer app. This is crucial for troubleshooting hardware components, checking battery health, or confirming network connectivity details.
The primary secret code to access the main hidden menu on most Moto G Stylus 5G models is: *#*#4636#*#*
Main Body: Accessing the Hidden Testing Menu
The *#*#4636#*#* code is the most reliable way to access advanced system information on the Moto G Stylus 5G.
Step-by-Step Instructions
- Open the Phone Dialer App: Tap the application you use to make phone calls.
- Enter the Code: Type the following sequence of characters exactly as shown: *#*#4636#*#*
- Automatic Launch: Unlike dialing a regular number, you do not need to press the “Call” button. The Testing menu should launch instantly upon entering the final asterisk (*).
Key Information Found in the Testing Menu
Once the Testing menu loads, you will typically find three main sub-sections:
| Menu Section | Information Displayed | Use for Troubleshooting |
| 1. Phone Information | Detailed information on the IMEI, signal strength (in dBm), data network type (LTE, 5G NR), voice service status, and cellular connection details. | Crucial for optimizing network performance or diagnosing poor signal strength. Some versions also allow access to 5G/LTE debugging info. |
| 2. Usage Statistics | A log showing the last time each application was used and the total usage duration. | Useful for monitoring your own or a family member’s app activity. |
| 3. Wi-Fi Information | Details about your current Wi-Fi connection, including SSID, signal strength, and network status. | Handy for running a basic Ping test or diagnosing connection issues without leaving the menu. |
Other Useful Moto G Stylus 5G Secret Codes
While the 4636 code is the primary hidden menu, several other codes offer instant access to specific diagnostics and system information.
| Code | Description | Function/Purpose |
| *#06# | IMEI Info | Instantly displays your device’s International Mobile Equipment Identity (IMEI) number(s). Essential for theft reporting, warranty claims, and carrier unlocking. |
| *#*#225#*#* | Calendar | Displays information stored in your Calendar, such as event details and sync status. |
| *#*#426#*#* | FCM Diagnostics | Accesses the Firebase Cloud Messaging diagnostics screen, showing connection status and history with Google’s servers. Useful for diagnosing delayed notifications. |
| *#*#2486#*#* | Engineering Mode | On some Motorola models (especially older or carrier-locked versions), this launches a more advanced diagnostic testing suite (CQATest app). |
| *#07# | Regulatory Info | Displays the electronic label showing official model numbers, FCC ID, and required regulatory compliance information. |
Note on Carrier and Model Variations
It is important to know that secret codes are dependent on the specific phone model and the carrier’s software customization. If a code does not work on your Moto G Stylus 5G (especially if it is a carrier-locked version), the code may have been disabled by the service provider.
Alternative: Accessing Developer Options
If you are looking for advanced settings related to the Android operating system, you should enable Developer Options, which is a separate, hidden menu accessible through the main Settings app.
How to Enable Developer Options
- Go to Settings (swipe up from the home screen and find the gear icon).
- Scroll down and tap About phone.
- Scroll down to Build number.
- Tap the Build number seven times rapidly. You will see a message confirming, “You are now a developer!”
- Access the Menu: Go back to Settings, then tap System > Developer options.
Useful Settings in Developer Options
- USB Debugging: Allows communication between your phone and a computer using the Android Debug Bridge (ADB).
- Stay Awake: Keeps the screen on while the phone is charging.
- Animation Scales: Allows you to speed up the interface by reducing window and transition animations.
Frequently Asked Questions (FAQ)
What if the code *#*#4636#*#* doesn’t work on my phone?
If the code does not work, it is likely disabled by your carrier’s firmware. A common workaround involves booting into a special mode to temporarily enable the full diagnostic tools:
- Power down your phone.
- Hold the Power button and both Volume buttons at the same time until the Fastboot menu appears.
- Use the Volume keys to navigate to “BP Tools” and select it with the Power button.
- Your phone will reboot, and an app called “CQATest” should appear in your app drawer, which provides similar diagnostic capabilities.
Is the Stylus Shortcut Menu a “Hidden Menu”?
No, the Stylus Shortcut Menu is a standard, user-facing feature. It automatically appears when you remove the stylus and offers quick access to apps like Moto Note, the Handwriting Calculator, and screen capture tools. This feature is not a hidden diagnostic menu.
Is it safe to use these secret codes?
Yes, the codes listed here are generally safe and non-destructive, as they only display information. However, within the Testing Mode (*#*#4636#*#*), there are advanced network settings. You should avoid changing any network configurations unless you fully understand the technical implications, as incorrect changes could affect your ability to connect to your carrier’s network.
