1. Turn on the emergency call screen
Each phone is set up with an emergency call feature in case of emergency. To activate the emergency call button, the user holds down the power button and the volume up button (Volume +) on the iPhone at the same time for about 3 seconds, then the screen will display 3 features including power off, display the phone owner’s medical information and emergency call.
If you do this continuously, the phone will display a countdown timer and automatically call the emergency number after the countdown ends. Note that to use the automatic emergency call feature, the user must set up an emergency phone number in Settings, enable providing information about the situation and locating the device, data about the phone owner’s blood type and medical conditions will be sent to the rescue unit in case of emergency.
2. Turn off the power or Find My
The power off operation using the volume button is very familiar to many iPhone users. Users just need to hold down the volume up key and the power button for 3-5 seconds and select Power Off.
In addition, Apple also supports the Find My off feature, which means that when the phone is turned off, the device’s location will also be turned off. When the phone is turned on, the Find My service will work again.
3. Camera control
The volume button of iPhone models can replace the on-screen photo capture button. This operation is to support users in case they take selfies or it is inconvenient to press the capture button on the screen.
To use this feature, users turn on the iPhone camera application, then press the volume up button after posing to take a photo.
The text outlines three features available on iPhones related to emergency calls, power management, and camera operation.
1. Emergency Call Screen: By holding the power and volume up buttons for about 3 seconds, users can access the emergency call screen, which includes options to power off the phone, view medical information, and initiate an emergency call. Automatic emergency calling can be set up by configuring an emergency contact in settings.
2. Power Off and Find My: Users can turn off the iPhone by holding the volume up and power buttons for 3-5 seconds. The Find My feature can be toggled off when the phone is powered down, and will reactivate once the device is turned on again.
3. Camera Control: The volume button can be used as a shutter button for taking photos, allowing users to capture images without tapping the on-screen button—simply press the volume up button while using the camera app.
