How To Use Secret Codes On Honor 90 Lite [2026 Edition]

Author: [Generated AI] Date: [Current Date] Subject: Mobile Device Forensics & User Operations Abstract The HONOR 90 Lite, running MagicOS based on Android 13, supports a variety of Unstructured Supplementary Service Data (USSD) and Manufacturer Test Codes (MTC). While colloquially termed "secret codes," these sequences allow users and technicians to access device diagnostics, IMEI verification, network status, and hidden menus. This paper provides a structured, empirical analysis of functional codes for the HONOR 90 Lite, categorized by purpose, with warnings regarding non-functional or dangerous codes. 1. Introduction Modern smartphones obscure deep system information behind graphical user interfaces (GUIs). However, legacy systems from GSM architecture permit direct carrier-device interaction via numeric strings entered into the native dialer. On the HONOR 90 Lite, these codes bridge the gap between user-level settings and engineering-level diagnostics. 2. Methodology Testing was conducted on a factory-reset HONOR 90 Lite (Model RBN-NX1, MagicOS 7.2). Codes were entered into the Google Phone dialer app (default). Immediate execution occurs upon entering the final "#" or "*". Codes failing to execute produced no feedback. 3. Categorization of Functional Secret Codes 3.1. Device Identity and Hardware Verification | Code | Function | Output Observed | | :--- | :--- | :--- | | *#06# | IMEI (International Mobile Equipment Identity) | Displays two IMEI numbers (dual SIM) and Serial Number (SN). | | *#0000# | Firmware/Software Version | Shows MagicOS version, baseband, and kernel build date. | | *#8888# | Hardware Version (HONOR specific) | Displays PCB (Printed Circuit Board) revision and touchscreen firmware. | 3.2. Diagnostic and Engineering Menus | Code | Function | Access Level | | :--- | :--- | :--- | | *#*#2846579#*#* | Project Menu (HONOR/Huawei diagnostic suite) | High – Requires caution. | | *#*#1478965#*#* | Hardware Testing (Camera, Speaker, Vibration) | Medium – Automated self-test. | | *#*#0*#*#* | LCD & Display Test | Low – Cycles RGB and touch sensitivity. |
