This work analyzes the features of design and user-interface of the smartphones exclusively designed for the elderly citizens in a bid to enhance their usability among people aged 65 or more to overcome digital divide in the ageing society of today. These features are more focused on size of the device, visibility, text-speech function and emergency tools. It was found that ageingfriendly smartphones have metallic body structure, large display, icons and text fonts, simplified navigation, text-to-speech and speech-to-text feature, and technical and emergency support facilities. Although all of these features successfully address the inabilities of seniors and explain the nature of usability of smartphones among them, there is a need to move towards more universal and inclusive designing of user-interface of smartphones for their universal adoption.
