Ever handed your phone to your child and wished there was a safer way to let them use it? Or struggled to move the cursor just right while editing a message? Smartphones are full of features that most users never discover—some strange, some incredibly useful. From tapping the back of your phone to trigger actions, to setting up guest modes for children, both iPhones and Androids offer hidden tools that can make everyday tasks easier and safer. At Phone Repair NZ, we’ve rounded up some of the most overlooked features that Christchurch families should know about—because knowing your device inside out is just as important as keeping it in working order.

Hidden Features on iPhones

Back Tap (iPhone 8 and Newer)

Back Tap allows users to assign shortcuts to a double or triple tap on the back of their iPhone. This can include taking a screenshot, muting the phone, or launching an app.

How to access: Settings > Accessibility > Touch > Back Tap

Ideal for: Quick actions when multitasking or for accessibility support.

Keyboard Trackpad Mode

Holding down the space bar transforms the keyboard into a trackpad, enabling precise cursor movement.

How to use: Press and hold the space bar until the keyboard grays out.

Ideal for: Editing messages or documents with greater control, particularly for parents or professionals managing tasks on the go.

Sound Recognition

The iPhone can be set to recognise specific environmental sounds—such as a doorbell, crying baby, or fire alarm—and notify the user.

How to enable: Settings > Accessibility > Sound Recognition

Ideal for: Parents, caregivers, or users with hearing impairments, adding another layer of safety at home.

Screen Time Downtime

Downtime restricts access to selected apps during set hours, helping to manage screen habits.

How to enable: Settings > Screen Time > Downtime

Ideal for: Encouraging children to disconnect during homework time or bedtime.

Hidden Features on Android Devices

Guest Mode

Guest Mode creates a clean, limited user profile, preventing access to personal apps and data.

How to enable: Settings > System > Multiple Users > Add Guest

Ideal for: Letting children or friends use your phone safely, without compromising your privacy.

Magnification Gestures

Users can zoom in on any part of the screen, regardless of the app.

How to enable: Settings > Accessibility > Magnification

Ideal for: Users with visual impairments or older family members who need larger text.

Screen Pinning

Pinning an app keeps the user locked into a single screen, preventing navigation elsewhere.

How to enable: Settings > Security > Screen Pinning

Ideal for: Giving a child access to a single game or video without risk of accidental calls or purchases.

Digital Wellbeing Dashboard

This tool tracks app usage and allows time limits to be set, helping manage digital habits.

How to access: Settings > Digital Wellbeing & Parental Controls

Ideal for: Parents monitoring screen time or encouraging healthier phone use at home.
