A smartphone is a mobile device designed for making phone calls but also has computer-like functionality through apps and internet access. Research has found that smartphones affect productivity, communication, social engagement, and education. Smartphones have connected people globally for social networking and can be considered a basic need, but have also increased access to threats like pornography and enabled suicidal attempts. Smartphones have also improved productivity through organization, access to company networks, and allowing work to be done anywhere. However, they have reduced physical workloads and made society more relaxed. Smartphones have benefited education by giving students global access to information anywhere through internet and apps, improving understanding with multimedia. They allow information sharing between students and teachers regardless of location.
