A mobile phone has many visible outer parts and internal parts that support display, touch input, calling, charging, storage, and connection. The main groups include the phone body, screen and front parts, side buttons, back camera area, ports, and internal parts, while smaller features such as the bezel, SIM tray, flash, speaker grille, and antenna help each section perform a more specific role.
