Over the last decade, mobile technologies such as smartphones and tablets have become an integral part of people’s daily life. While only 18% of Internet users in Germany used a smartphone in 2011, this rate increased to 78% in 2019, among people aged 16-24 even to 95% (Destatis 2011, 2020), with similar trends observed in other countries (Silver 2019). Smartphones have become an everyday companion that people not only use for calling and texting but also for interaction on social media, news consumption, entertainment, and navigation, among many other things (Perrin 2017).
