One of the main characteristics of smartphones is the screen. Depending on the device’s design, the screen fills most or nearly all of the space on a device’s front surface. Many smartphone displays have an aspect ratio of 16:9, but taller aspect ratios became more common in 2017.
Screen sizes are measured in diagonal inches. Phones with screens larger than 5.2 inches are often called “phablets”. Smartphone with screens over 4.5 inches in size are commonly difficult to use with only a single hand since most thumbs cannot reach the entire screen surface; they may need to be shifted around in the hand, held in one hand and manipulated by the other, or used in place with both hands. Due to design advances, some modern smartphones with large screen sizes and “edge-to-edge” designs have compact builds that improve their ergonomics, while the shift to taller aspect ratios has resulted in phones that have larger screen sizes whilst maintaining the ergonomics associated with smaller 16:9 displays.
Some audio-quality enhancing features, such as Voice over LTE and HD Voice have appeared and are often available on newer smartphones. Sound quality can remain a problem due to the design of the phone, the quality of the cellular network, and compression algorithms used in long-distance calls. Audio quality can be improved using a VoIP application over WiFi. Cellphones have small speakers so that the user can use a speakerphone feature and talk to a person on the phone without holding it to their ear. The small speakers can also be used to listen to digital audio files of music or speech or watch videos with an audio component, without holding the phone close to the ear.
Cameras have become standard features of smartphones. As of 2019 phone cameras are now a highly competitive area of differentiation between models, with advertising campaigns commonly based on a focus on the quality or capabilities of a device’s main cameras.
