Recently I tried exchanging numbers with a friend who has a burner phone - a replacement for a lost phone.
Yes, good luck with dialling a number or storing a number in the contacts. Even sending a text is a trial of user experience, an intelligence test akin to solving a Rubik's Cube.
So it is good to see that a 12 year old can work out some of these functions. I completely failed to exchange phone contact numbers with my friend, with ten minutes of trying.
