Touch screen mobile phones can be divided into resistive screen and capacitive screen mobile phones, which refers to a kind of mobile phones that use touch screen technology to apply this technology to mobile phone screens. There is no clear boundary between touch-screen mobile phones and other mobile phones. The biggest feature is its large screen.
