Configuring an iPhone to be primarily a voice controlled phone.
A family member, with failing sight and unsteady hands, needs a mobile phone. Full voice control is needed. Phones on the market for this don't do the complete job. They require either good vision, or steady hands. If I could disable haptics while keeping voice commands (Siri or Voice Control) available, that would be ideal. Obviously, it would still be necessary to be able to take the phone out of voice-only mode so it could be maintained by other family members, but then easily set back into voice-only mode.
Guided access would seem to be a good option as it does make it possible to turn off the haptics, but voice control appears to be automatically disabled, too (tested on both an 11 and 12 iPhone with Ios 16.1). Also, it would make messaging inaccessible, since it locks the interface to a single app. He would have to exit Guided Access, start the message app and then restart Guided Access. His haptic control is not good enough to enter the Guided Access passcode. (Voice control custom commands can't do this either. As the passcode dialog doesn't respond to either spoken or gesture commands, only physical taps.)
There are some piecemeal configs I have found, like preventing the side button from hanging up, but there is no full solution. Short of reversing the case so it's over the screen and physically disabling the volume buttons, I'm not sure what to do.
Am I missing something?
Can Apple look at this as an accessibility use case and design a solution for it?
Thank you for any help
