In popular technology culture, 4636 is also known for an Android-related hidden code. On many Android devices, dialing the sequence *#*#4636#*#* opens a Testing or diagnostics menu. This menu typically provides access to several sections, such as Phone information (which can reveal device and network details), Battery information (level, health, voltage), Usage statistics (app usage data), and Wi-Fi information (current connection details and link speed).

The availability and contents of the hidden menu vary by device, Android version, and vendor customization. The code is not an official standard or supported feature, and its presence is largely at the discretion of device manufacturers and carriers. Consequently, some devices may not respond to the code or may restrict access to certain sections for security or privacy reasons.

Overall, 4636 serves as both a mathematical integer with a defined factorization and a culturally notable reference to an unofficial diagnostic shortcut that has become part of Android lore.
