The INFINIX Note 11, powered by MediaTek’s Helio G-series chipset, runs on XOS (based on Android 11/12). Like many Android smartphones, it supports a series of USSD (Unstructured Supplementary Service Data) and MMI (Man-Machine Interface) codes. These “secret codes” allow users and technicians to access hardware diagnostics, testing menus, and device information not typically available through the standard settings menu. This paper provides a categorized list of functional codes for the INFINIX Note 11, explains their proper usage, and outlines important safety precautions.

The INFINIX Note 11 is a powerhouse of a budget smartphone, boasting a 6.95-inch display, a 50MP camera, and a 5000mAh battery. But beneath its sleek glass and metal exterior lies a hidden world of diagnostic tools, engineering menus, and system information. This world is accessed via "USSD codes" or "secret codes."

These codes open the , allowing you to test individual hardware components.

*: Sometimes used to access a hidden menu for device information.

The most straightforward way to use a secret code is to open the default Phone dialer app on the INFINIX Note 11. Do not use a third-party dialer. Input the code exactly as written, without pressing the call button; the phone will automatically recognize the sequence and execute the command. For example, typing #06# instantly brings up the device’s IMEI (International Mobile Equipment Identity) numbers—critical information for network locking and warranty claims. Similarly, entering #07# displays SAR (Specific Absorption Rate) values, which indicate the device’s radio frequency exposure. Another useful code is # #225# # , which opens the "Hardware Test" menu, showing details about the battery, temperature, and other hardware metrics.
