Other features typically include a personal digital assistant (PDA) for making appointments in a calendar, media player, video games, GPS navigation unit, digital camera and digital video camera.

Features often found in smart phones

  • Create and edit office documents using Open Office, Microsoft Office software
  • Based on advanced operating systems such as Android, Windows Mobile, or Apple IOS.
  • Enabled with sensors such as GPS, Accelerometer, Gyroscope, and magnetometer. GPS can be used to locate places while traveling. Accelerometers handle axis-based motion sensing and can be found in fitness trackers as well as phones-they're the reason why your smartphone can track your steps even if you haven't bought a separate wearable. A gyroscope is a device used for measuring or maintaining orientation and angular velocity. The gyroscope helps the accelerometer out with understanding which way your phone is orientated. Magneto meter is an instrument for measuring the intensity of a magnetic field, especially the earth's magnetic field. A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact.
  • When it comes to messaging, a smart phone will send messages and also emails. A smart phone can synchronize your email accounts with that of the mail server. Some smart phone can support multiple accounts depending on the operating system and the email client software.

Tablets: A tablet, or tablet PC, is a portable computer that uses a touchscreen as its primary input device. Most tablets are slightly smaller and weigh less than the average laptop.
