My dad has had an android phone for about 3 years now. He just learnt that the big circle at the bottom takes you to the home screen. I love my dad.

What??? How? Did he just somehow never use the home screen? Or just used the back button?

@Toasty He just spammed the back button until he landed on the homescreen. Yesterday he came to ask me for help because he was stuck. He had been using the web browser for a while and was so confused because the back button always took him to the last web page instead of quitting the app
