How to Use Secret Codes on HONOR 90 Lite: The Ultimate Guide to Hidden Menus In the world of smartphones, what you see on the surface is rarely the whole story. Beneath the polished MagicOS interface of your HONOR 90 Lite lies a hidden layer of diagnostic tools, engineering menus, and statistical counters. Accessing these features doesn’t require root access or third-party apps. Instead, you can unlock them using USSD codes (often called secret codes or MMI codes). If you have ever wondered how to test your hardware, retrieve advanced device statistics, or perform a quick factory reset without navigating through the Settings app, this guide is for you. Here is everything you need to know about how to use secret codes on HONOR 90 Lite .

What Are Secret Codes (USSD Codes)? Secret codes are sequences of numbers and symbols (usually starting with *# or *#*# and ending with # or #*#* ) that trigger specific functions in the Android system. On HONOR devices (a subsidiary of Huawei), these codes interact with the phone’s radio interface layer (RIL) and built-in testing software. Important Disclaimer: Not all codes work on every device. HONOR has locked down some codes in newer versions of MagicOS. Additionally, be extremely careful with codes that initiate resets or formatting—they cannot be undone.

Preparation: What You Need Before You Start Before you learn how to use secret codes on HONOR 90 Lite , follow these steps:

Open the Stock Dialer: Secret codes only work in the default HONOR Phone app. Third-party dialers like Google Phone or Truecaller may block them. Disable Dialer Add-ons: Turn off "Caller ID & Spam Protection" temporarily, as these services sometimes intercept codes. No SIM Required: Most diagnostic codes work perfectly in Airplane Mode or without a SIM card. Enter Codes Quickly: Type the code exactly as shown. Do not press the call button—most codes execute automatically as soon as you type the final character ( # ). How to Use Secret Codes on HONOR 90 Lite

The Most Useful Secret Codes for HONOR 90 Lite Below is a verified list of codes that work on MagicOS 7.1 (and later) running on the HONOR 90 Lite. 1. The All-in-One Diagnostic Menu: *#*#2846579#*#* This is the most powerful code on HONOR devices. It opens the Project Menu (also known as the Engineering Menu). Unlike basic testing menus, this provides hardware-level information. What you can do here:

Background Setting: Enable full USB debugging and engineering logs. Network Information Query: Check your IMEI (International Mobile Equipment Identity), MAC address, and Bluetooth address without going to Settings. Software Upgrade: Force a micro-upgrade check (useful for unreleased updates). Veneer Information: View PCBA (printed circuit board) serial numbers and manufacturing dates.

Pro tip: Use the "Network Information Query" > "IMEI" to quickly copy your IMEI numbers for carrier unlocks or warranty claims. 2. The Standard Testing Menu: *#*#0#*#* On Samsung phones, this is a full diagnostic tool. On the HONOR 90 Lite, this code triggers a LCD & Touchscreen Test . Your screen will cycle through red, green, blue, and white colors. Tap the screen to exit. This is perfect for checking for dead pixels or backlight bleeding. 3. The Complete Hardware Test (HONOR/Huawei Specific): *#*#121314#*#* This code launches the HONOR Auto-Test Suite . It runs a sequential diagnostic of: How to Use Secret Codes on HONOR 90

Vibration motor Earpiece and loudspeaker Microphone (primary and secondary) Proximity sensor Ambient light sensor Fingerprint sensor (HONOR 90 Lite has side-mounted fingerprint)

Unlike manual tests, this one prompts you to confirm each function, making it beginner-friendly. 4. Battery and Charging Stats: *#*#121314#*#* (Reused for Health) Wait—the same code as above? Yes. When you run the auto-test, one of the modules checks battery temperature, voltage (in mV), and charging current (in mA). For a quick view of your battery health without running the full test, try *#*#121314#*#* and cancel other tests, or use *#*#2846579#*#* > "Background Setting" > "Power Monitor". 5. IMEI and Serial Number: *#06# The universal standard. Type *#06# and your HONOR 90 Lite will immediately display both IMEI 1 and IMEI 2 (for dual SIM) along with the MEID. Take a screenshot of this—it’s essential for insurance claims. 6. Usage Statistics and Timer: *#*#4636#*#* This Android classic opens the Testing menu . While some features are restricted on HONOR, the following sections work:

Phone Information: View signal strength (RSRP in dBm), cell tower information, and network type (LTE/NR). You can also set "Preferred Network Type" (e.g., force LTE only to save battery). Usage Statistics: See which apps you have opened recently and for how long (app timers). Wi-Fi Information: Show detailed Wi-Fi connection logs. Instead, you can unlock them using USSD codes

Note: The "Battery health" section is often blank on MagicOS; use the auto-test instead. 7. Camera Firmware and Calibration: *#*#34971539#*#* This code reveals the Camera ISP (Image Signal Processor) firmware. On the HONOR 90 Lite’s 100MP main camera, you can:

View camera sensor type (Samsung or Sony). Check lens calibration date. Update camera firmware manually (if available).
