Unlike a Samsung Galaxy or an iPhone, the ZTE Blade L220 is not a full Android smartphone. It runs on a proprietary, lightweight RTOS (Real-Time Operating System) or a stripped-down version of Android (depending on the regional variant).

Firmware is the permanent software programmed into the device’s read-only memory. It acts as the master controller for:

  • The physical hardware (keypad, screen, battery management)
  • The network radios (2G/3G/4G connectivity)
  • The basic user interface and menu system
