Accessibility is not one “easy mode”. Choose and test the combination of vision, hearing, mobility, speech and cognitive features with the person who will use the phone.
Build around tasks
| Need | Features to test |
|---|---|
| Low vision | Text size, magnification, contrast, screen reader |
| Hearing | Hearing-device streaming, captions, vibration and visual alerts |
| Limited dexterity | Voice Control/Voice Access, AssistiveTouch, Switch Access, one-handed mode |
| Cognitive support | Simplified home screen, reduced motion, guided access and clear routines |
Test before relying on it
- Set the intended text, sound and control options.
- Make an ordinary call and read a message.
- Try the recovery passcode and emergency information.
- Restart the phone and confirm shortcuts remain usable.
- Record the setup for a trusted helper without taking ownership of the account.
Keep ownership with the user
Use the owner’s own Apple or Google account and explain what a helper can access. Accessibility should increase independence, not silently transfer control of photos, messages, payments or recovery to another person.
Run a real-world trial
- Let the intended user perform the setup, not only watch a helper.
- Test calls, messages, camera, payment and recovery.
- Try the phone in noise, bright light and the usual grip.
- Confirm that shortcuts survive restart and lock-screen use.
The strongest feature list is irrelevant if the user cannot reliably recover from an accidental gesture, update or locked screen. Independence and reversibility are core accessibility requirements.
Build the setup around one independent outcome
Use this hub to identify the barrier before choosing a feature: seeing content, hearing calls, touching controls, speaking commands or understanding a complex interface. The right route may combine hardware, system settings and a better-designed app rather than enabling every accessibility option at once.
- Choose one task the user currently cannot complete reliably.
- Test the smallest set of changes that solves it.
- Record a shortcut and support route so the user can recover if the interface becomes confusing.
Choose the right decision guide
Use this section to identify the actual barrier—seeing, hearing, touch, reach or text entry—and test the relevant feature with the person who will rely on it.
- Check or verify: Hearing Aid Compatibility with Smartphones.

When this hub has done its job
The user should complete the target task independently and know how to undo an accidental setting or reach help without losing account ownership.
