Hi! We understand your concern and we'd be glad to help! Here are the steps you can do to enable AsssistiveTouch if you're having trouble using physical buttons on your iPhone:
- Go to Settings
- General
- Accessibility
- Scroll down until you see AssistiveTouch
- Enable it on the next screen. A dark grey square button should appear on any side of your screen.
You can customise which controls will appear once you open AssistiveTouch by tapping Customise Top Level Menu...
You can also assign specific actions when you either long-press or double-tap the AssistiveTouch button.
I hope this answers your question. Have a great day!
