There is no doubt that, in the last ten years, smartphones have not stopped increasing in size. The size of the screen is an important factor when buying a phone for the elderly, since it allows them to view the contents effortlessly.
A larger screen makes it easier to view media content like movies and videos, as well as apps with prominent buttons for those who need extra help interacting with their device.
The goal is to get the largest, highest quality screen possible without making the smartphone too heavy to carry around. Currently, the screen sizes of smartphones range from 4.7 to 6.7 inches.
