Understand certain differences in Assistive Access on iPad
Assistive Access apps have been redesigned for cognitive accessibility and include larger text and icons, more focused features, and customizable options. In addition, some features work differently in Assistive Access—this page explains certain important situations where you need to exit Assistive Access.
App permissions
To minimize pop-ups while using iPad, apps won’t ask for permission to access information such as location, photos, and contacts. Instead, you have the option to set access permissions for apps when you set up Assistive Access. To review or change an app’s permissions, you must exit Assistive Access and go to Settings 
> Accessibility > Assistive Access or Settings > Apps > [app name].
Software updates
You must exit Assistive Access and go to Settings in order to install new software updates, because there is no Settings app or notifications in Assistive Access that indicate whether an update is available.
Privacy and device information
Certain app privacy information, status icons, and symbols aren’t available in Assistive Access, including those that indicate network availability, Airplane Mode, Focus, or Bluetooth®, or when an app or website is using Location Services. You can exit Assistive Access to view this information.
Calls and messages
When you set up Calls for Assistive Access, you can choose to allow calls with anyone, all contacts in the Contacts app, or favorite contacts only. If you choose to allow calls to anyone, the person using Assistive Access can call any contact, as well as return calls from anyone who has called them. If you don’t allow calls with everyone, you must exit Assistive Access to call anyone who’s not an allowed contact. Even if you allow calls to anyone, you must exit Assistive Access to call someone who’s not an allowed contact if they haven’t already called you.
When you set up Messages for Assistive Access, you can choose to allow messages with anyone, all contacts in the Contacts app, or favorite contacts only. If you choose to allow messages to anyone, the person using Assistive Access can send a message to any contact, and return messages from anyone who has messaged them. If you don’t allow messages with everyone, you must exit Assistive Access to send or receive messages from anyone who’s not an allowed contact. Even if you allow messages to anyone, you must exit Assistive Access to send a message to someone who’s not an allowed contact if they haven’t already sent you a message.
