Video explanation
An older Sony phone expands into eight layers, highlighting its display, keypad, circuit board and antenna, then demonstrating power and call states.
Assembly through exploded views
Separating layers reveals relationships between the housing and modules. It is a structural illustration, not a repair sequence.
Input and display
Keys provide input, the circuit board processes state, and the LCD displays updates. The display itself does not handle wireless calls.
Power and radio
A battery supplies energy while the antenna and radio circuitry handle signals. The animation connects these parts with power-on and dialing actions.
