A phone is a small computer

See your phone as the machine you have already learned about — which means everything you know already applies to it.

A smartphone is not a different kind of thing from a computer. It is a computer — the same processor, the same memory, the same storage, the same connection to the internet — built into something that fits in a coat pocket.

What genuinely is different comes to four things, and none of them changes how the machine works underneath.

Nearly every tap, hold and swipe on a phone can be undone or backed out of. Screens can be left, settings can be changed back, apps can be reinstalled, and there is a Back arrow or an edge swipe on almost every screen ever drawn.

The genuinely permanent things are a short list, and most of them ask you to confirm before they happen — deleting photographs, erasing a phone, closing an account. Buying something is the one that often does not ask again, because your fingerprint or your face has already answered for you. That is the one to slow down for.

What to remember

Try this

Open Settings on your own phone and scroll slowly to the bottom without pressing anything. Reading the list once, with no task in mind, makes it far less intimidating the day you need something from it.
