iPhone The Complete Manual

From the first setup screens to the finer points of iPhone apps, this illustrated manual takes a practical, feature-by-feature look at using an iPhone with iOS 26. It begins with the essentials, then moves into the operating system’s Liquid Glass design, built-in apps and selected newer features—so readers can start with what they need and explore further as they go.

Start with the essentials

The opening chapters cover the everyday foundations: buttons and ports, getting set up, Apple ID, Face ID, the Home and Lock Screens, folders, internet access, email, calls, the touchscreen, keyboard and Control Centre. This makes the guide useful for getting oriented as well as for looking up a particular feature when a question comes up.

Make sense of iOS 26

A dedicated introduction explains what iOS is, why the version number changed to 26, and what the Liquid Glass interface means for the look and feel of the iPhone. The guide also surveys selected changes involving apps and features such as Games, Preview, accessibility, AirPods and CarPlay.

Get more from the built-in apps

App-focused sections explore Mail, Safari, Reminders, Messages, Notes, Calendar and Contacts. Topics include email setup, undoing a sent message, voice and video messages, recovering deleted messages, and using Notes to type, write or sketch. The emphasis is on understanding what familiar apps can do and where to find their useful functions.

For newcomers and curious iPhone users

The contents move from introductory guidance to more advanced subjects, including iCloud Drive, StandBy and Siri. That makes this manual a practical reference for people learning the basics and for existing users who want to explore features they may not yet use.
