PDA Phone

A smartphone is a mobile personal computer with a mobile operating system with features useful for mobile or handheld use. Smartphones, which are typically pocket-sized (as opposed to tablets, which are much larger in measurement), have the ability to place and receive voice/video calls and create and receive text messages, have personal digital assistants (such as Siri, Google Assistant, Alexa, Cortana, Bixby), an event calendar, a media player, video games, GPS navigation, digital picture camera and digital video camera. Smartphones can access the Internet through cellular frequencies or Wi-Fi and can run a variety of third-party software components ("apps" from places like Google Play Store or Apple App Store). They typically have a color display with a graphical user interface that covers more than 76% of the front surface. The display is almost always a touchscreen and sometimes additionally a touch-enabled keyboard like the Priv/Passport BlackBerrys, which enables the user to use a virtual keyboard to type words and numbers and press onscreen icons to activate "app" features.
